♪♪

Its pristine waters are among
the world's most beautiful,

but could the island paradise
of Turks and Caicos

hold the answers to
a long‐standing Nazi mystery?

Magnetometer, ROV‐‐

you name it, it's in our bevy
of electronic tricks.

FISHBURNE: Can a team
of divers follow clues

left by famous
treasure seeker Roger Miklos

to hunt and find
a Nazi U‐boat?

It's sitting in British waters,
in the Caribbean.

INTERVIEWER: But you won't
say exactly where?

No, I'm trying to keep that
protected

as much as I can.

FISHBURNE:
A submarine he believes

is full of gold
and other priceless treasures.

ROGER: There was 18

high‐ranking Nazi officials
on board,

all of them paintings.

There's 50 tons of gold
on that thing.

FISHBURNE: And what can
their search reveal

about the notorious
Nazi regime

and the end of World War II?

The code is cracked.
We now have a location.

Tonight, on
"History's Greatest Mysteries,"

we follow the trail of clues

to search for the Nazis'
top secret lost U‐boat

and its astonishing contents.

Using original documents
never seen by anyone

other than Roger Miklos himself,

a team of divers will attempt
to unlock the mystery

and find what many consider

the most elusive shipwreck
in history.

Guys, I think I got a hit!

I'm Laurence Fishburne,

and tonight, can Mike Fletcher
finish the mission

that Roger Miklos started
so many years ago?

♪

FISHBURNE: Off the coast
of Florida

and just 384 miles from Cuba,

lay the islands
of Turks and Caicos.

Their beauty, color,
and perfect weather

makes these islands
a destination

for travelers worldwide.

But looks can be deceiving.

Under these turquoise waters,

the terrain is jagged,
unpredictable,

and often deadly.

And these islands are
a graveyard of sunken vessels

and lost treasure.

And that's where Mike Fletcher
comes in.

MIKE: You name it,
I've done it underwater.

I started out with a passion
for maritime history

and specifically shipwrecks.

And then when you combine that
with my ability

to dive in deep,
difficult conditions,

I got really good
at finding shipwrecks.

I get a lot of attention
for having found the Carpathia,

which was the ship that saved
the Titanic survivors.

I found three
really significant submarines.

‐ Mike?
‐ I think we got ourselves

‐ a submarine.
‐ Whoo‐hoo!

MIKE: Two famous U‐boats,

so this would be the third.

I went from being
a commercial diver

to a recognized,
international shipwreck finder.

FISHBURNE: Mike has been
finding sunken vessels

for over 40 years.

But today, he begins the hunt
for a shipwreck

unlike any other in history.

Out of the blue one day,

I get a call from this guy
I've never met.

And he says,
"Mike, can we get you

to go on a mission for us?"

Turns out that mission
was following up

on treasure hunter
Roger Miklos's claim

that he had found a U‐boat
full of Nazi treasure.

FISHBURNE: Forty years ago,
treasure hunter Roger Miklos

claimed to have discovered
a U‐boat

on the ocean floor off
an island of Turks and Caicos.

During World War II,

Nazi U‐boats terrorized
the Atlantic,

sinking over 2,500 ships.

NEWSREEL ANNOUNCER:
Official Navy pictures

of the smashing of a U‐boat

surprised on the surface
by carrier‐based planes.

FISHBURNE: By the end
of the war, the Allies had sunk

over 600 of these German subs.

NEWSREEL ANNOUNCER: A direct hit
from a depth charge!

Another Nazi menace destroyed.

FISHBURNE: But the U‐boat
Roger Miklos

claims to have found was not
just any German sub.

For decades there had been
rumors and stories

that in the waning days
of World War II,

the Nazis built a fleet

of nine specially modified
cargo subs

to ferry looted gold,
priceless artwork,

and possibly even top
Nazi officers to South America

as they attempted to flee
a crumbling Third Reich.

We do know that there's
billions of dollars

in looted
personal possessions, gold,

all sorts of valuable material
that went missing

during the war.

It certainly made sense
that some of this

could have been loaded
on U‐boats

to smuggle them out of Europe
and into a safe haven.

FISHBURNE: Over the years,

many U‐boats
have been discovered.

But no one has yet found
the specialized German subs.

Until, in 1981,
Roger said he had discovered

one of these subs.

They welded
all the torpedo hatches up,

removed all torpedoes,

for cargo,
for all the treasure.

FISHBURNE: If he was right,
it would be among

the greatest underwater
finds in history,

but Roger never told anyone
where the U‐boat was located.

Then in 2018, he died suddenly
of a heart attack,

leaving behind
only cryptic documents

and incomplete clues
as to where he found the U‐boat.

But now, Mike Fletcher
has those documents.

Miklos's family has hired Mike
to continue Roger's mission,

and they have turned
all of his records over to Mike.

It is the first time ever
that anyone

other than Roger Miklos
has had access

to these maps and records.

MIKE: No one else
has these documents.

Roger made sure
that no one else saw them.

There was a lot going on
in Roger's world,

but he didn't leave us
really good notes.

So much of what he leaves
behind is cryptic

and you can tell he was
being very secretive.

Roger's the only guy
who knows where it is.

So now we have to look
at his notes

and try and work backwards.

It's as if Roger's working
with us from the grave.

But he's not making it easy.

FISHBURNE: For 37 years,
Roger kept the location

of the U‐boat
a closely guarded secret.

But why?
Well, to understand that,

you need to know the story
of the man who discovered it.

My name's Roger Miklos.

And I've been
in the salvage business

for just about 56 years.

FISHBURNE:
Born in the Florida Keys,

Roger Miklos worked as
a police officer in Reno, Nevada

before the lure
of sunken treasure

drew him back to Florida
to seek his fortune.

Roger Miklos is here.

[cheers and applause]

FISHBURNE: At the time he says
he discovered the U‐boat,

Roger Miklos was already
a treasure‐hunting legend,

having collected between
$200 and $300 million

in sunken treasure
before the age of 40.

Roger was that perfect balance‐‐
a successful treasure hunter

who had the credibility
mixed with the showmanship.

FISHBURNE:
Roger's first major discovery

was the El Capitan,

a Spanish galleon
laden with gold and silver

that was lost off the coast
of Florida in 1715.

The gold pieces here are
all that exists

left of the El Capitan's
treasure.

There is no more available
anywhere.

I didn't think you were allowed
to keep, uh, treasures.

You see, when you salvage
treasure in Florida,

they get 25% for the State of
Florida, for the museums.

So then they turn the other 75%
over to the salvage company.

FISHBURNE: Throughout
his career as a treasure hunter,

Roger would continue to make
significant finds.

The Atocha yielded 148 million.

The El Capitan yielded
86 million.

The Maravillas yielded
a little over 100 million.

FISHBURNE: 35 years later,
Roger Miklos

gave his final interview
before his death.

Well, as far as the‐‐
[stammers]

as far as that I have‐‐
it's that U‐boat.

That's gotta be‐‐
and I'll tell you why.

Because...

You want to get into
the U‐boat?

I'll tell you the story of it.

FISHBURNE: Roger never set out
to find a U‐boat.

The story begins in 1981

when Roger traveled
to the Caribbean

to pick out a crew
for a new expedition.

ROGER: This is
Captain Jon Christiansen.

He is a Viking.

FISHBURNE:
Jon and Roger spent six weeks

sailing around
Turks and Caicos

on the hunt for the remains
of the Pinta,

one of the three ships Columbus
sailed to the New World.

One day, their magnetometer‐‐

the device that detects metal
objects on the sea floor‐‐

picked up something unusual.

ROGER: The magnetic field
is disturbed

by iron and heavy metals,
maybe a car, a refrigerator,

but it's definitely iron, man.

FISHBURNE: Roger went off
on his own to investigate.

This anchor here,
in the deep water,

I take the Zodiac
and take a look at it.

I swam down 45 feet.

I saw the two back
propeller blades

highly polished from going
in the sand,

up and down and in the sand.

And then there's
these enormous zeppelin fins

on this damn thing.

And I, "What the..."

FISHBURNE: Roger knew this
was something extraordinary.

ROGER: And I realized,
"Holy cow!

"This thing goes and goes
and goes!

It's under an island!"

And I got to the top
of the conning tower.

And then I noticed a glint,
a goldy glint color.

They put a commission plaque
in the teakwood deck

on the starboard side
of the conning tower.

And I rubbed
the grass off of it

and there it is, man.

"Blohm & Voss,
Hamburg, 1944,"

with a German eagle and
swastika on the ‐‐‐damn thing.

Now I know it's German.

This is a U‐boat.

FISHBURNE:
Roger returned to the ship,

but never revealed to his crew
what he had found.

The world of treasure hunting
is very cloak and dagger.

When you make a big discovery
like that,

there are people
hiding in the weeds

waiting to take it
away from you.

It's gotta be worth
a fortune, man.

But I don't know anything
about it.

So, I just let it sit.
Nobody gonna discover this.

MIKE:
Roger would've been okay

if he'd have just stayed
focused on the U‐boat,

got permissions
and pursued that.

FISHBURNE:
Instead, Roger continued

to search for the Pinta.

Days later, his crew
made a discovery‐‐

an anchor they believed to be
several centuries old.

This is us at the surface
transferring it

from the Captain Jack
to the Heather Glynn

and I'm a little shocked,
there standing.

This thing weighed
about 1,400 pounds

so they really had to get it
good and lashed

to swing it over on that boom.

FISHBURNE: What the crew
didn't know

was that the Turks and Caicos
government

had declared that Roger's permit
to salvage items

from the shipwreck was invalid.

And the next morning,
law enforcement officers

approached Roger's ship
with orders

to arrest him and the crew.

I told Christiansen,
"Pour the power on, dude.

We're outta here."

So all of a sudden,
I see the two cops

jumping in their little skiff
with this diesel motor in it,

and here they come, man,

firing away at us
with M‐16s.

Man, the bullets are ricocheting
off of my hull.

[gunfire]

I collected 168 rounds...

of bullets off of my deck.

FISHBURNE:
Roger and Jon escaped,

but the government
of Turks and Caicos

had now cut Roger off
from ever returning

to find his submarine.

Could the sunken sub
that Roger claimed to have found

be one of these modified
Nazi U‐boats?

Now, after examining
Roger Miklos's documents,

Mike has assembled a team
to look for the U‐boat.

Diver and underwater
photographer Chris Atkins.

When it comes to diving,
it's Chris Atkins.

He's very trustworthy.
He works hard.

He's my dive partner.
He's the underwater shooter.

FISHBURNE: An undersea
electronics and robotics expert,

Sam Macdonald.

MIKE:
Beyond Chris and myself,

we need somebody
with the tools.

We need the magnetometer,
we need the side scan,

we need an ROV because
we don't know how deep

we may have to go.

Sam Macdonald is the person
I turn to

for underwater robotics.

She not only develops and
operates this stuff,

she invents this stuff.

She brings all of the stuff
we need.

SAM: What have you got
for us today?

MIKE: We're gonna go
to the Caribbean

and look for one of
Hitler's missing U‐boats.

It was en route,
according to the story,

from Germany
to maybe South America

loaded with treasure
pilfered out of Nazi Europe

at the end of the war.

‐ Really.
‐ Wow.

Now Roger never told anybody
exactly where he'd found it.

All we know is it's
in the Turks and Caicos.

But Roger wasn't allowed
to go back into the country.

I am.

I've gone through that box.

I've read all the articles,

looked at the maps,
read the reports,

I think I've cracked the code.

FISHBURNE: Diver Mike Fletcher
is on the trail

of the lost Nazi U‐boat
claimed to have been discovered

40 years ago by treasure hunter
Roger Miklos.

Miklos was the only one
who knew the exact location

of the sub, and he wasn't
giving it up to anybody.

MIKE: I notice,
watching footage with Roger,

that he often carried
a briefcase.

And I know for a fact
he carried a .45.

He wasn't letting anybody know
what was in that briefcase.

But now I've got
that briefcase.

I get to look at the records
that Roger held so dearly,

that nobody else got to see.

Where is it?

Sitting in British waters
in the Caribbean.

But you won't say
exactly where?

No, I'm trying to keep that

protected as much as I can.

FISHBURNE: Now,
Mike has assembled his team

to go look for the U‐boat.

That is, if he can decipher
the mountain of clues

Roger amassed throughout
his decades of research into

the murky origins
of the Nazi submarine.

NEWSCASTER: This diagram,
superimposed

on an ordinary U‐boat,
shows that it has

special modifications for
long underwater journeys.

He says it's
in perfect condition.

FISHBURNE: Roger's research
convinced him

that this sub had been modified
to carry treasure.

ROGER: Here's the normal
conning tower

and all these machine guns
and stuff.

They eliminated all that,
they moved the bridge forward,

they modernized the bridge,
made it very narrow.

There's 50 tons of gold
on that thing.

All them paintings‐‐
Leonardos, Monets,

all of the famous works of art,
600 of 'em,

distributed between
these nine U‐boats.

Here's my original drawing of
the way that thing is set.

This is the overhang
of the island.

FISHBURNE: Roger's
descriptions of the terrain

where he found the U‐boat
were vague and secretive.

He said the sub was in
125 feet of water,

either partially under an
island or sticking out of a cave

that had a steep slope
on one side.

We're the only people

‐ to see this stuff.
‐ CHRIS: Really?

Roger Miklos was so paranoid

that somebody was gonna
find his U‐boat

that he never wrote
the location down.

‐ A true treasure hunter.
‐ Hmm.

I watched hours of Roger
talking to camera,

read all of his documents,
looked at his maps.

I think I've cracked his code.

The one thing you haven't seen
is this.

CHRIS: And what is that?

There's a simple pad of paper
that lists some

of the wrecks
that Roger's found

in Turks and Caicos.

At a glance, it didn't mean
anything to me.

But look there‐‐
French frigate.

Number 7,
"1724, French frigate."

And watch what Roger says.

And I coded the U‐boat
as a 1724 French frigate.

Nobody had a clue that
that wasn't a French frigate.

Old shipwreck.

He just said the French
frigate was code for the U‐boat?

So he's telling us
that he's keeping the code.

Towards the end, when Roger's
health was really failing,

it was like
he had one last chance

to tell the world
what he needed to say.

So by putting the yellow sheet,

Roger's words together,
the code is cracked.

We now have a location.

I think we make a trip
to Turks and Caicos.

♪♪

FISHBURNE: Seven weeks
after the team's first meeting,

Mike heads to Turks and Caicos

to get his first look
at the local topography.

It's not every day I get asked
to go on a submarine hunt.

Roger makes a big, big deal
about caves,

the idea that this submarine
is sort of part inside a cave.

So if I was gonna
take on this project,

I want to see if we can
find a cave

big enough to house a big
portion of a U‐boat.

We're here.

Somewhere out there,
where those waves are breaking,

should be Roger's U‐boat.

We know that a likely spot
would be on

a very craggy ocean bed
with cliffs

and perhaps valleys.

So if I get underwater
and I don't see

those topographical features,

this trip will have been
a big waste of my time.

FISHBURNE: Given the vast area
to look in,

Mike decides to approach
the search methodically.

His first step‐‐investigate
the underwater landscape.

If the underwater geography

doesn't match
Roger's descriptions,

he could scrap
the entire expedition.

MIKE: I'm finally gonna
see for myself

if there's anything
to Roger's story.

The moment of truth.

I'd never visited
Turks and Caicos before,

and certainly the geography
of what Roger describes,

everything's adding up.

This is a really, really
craggy seabed.

It's not like anything you
normally see

with big overhangs and
sharp drop‐offs and gullies.

This is the overhand
of the island

that goes way out there
about 400 feet.

And there's a shelf
that comes up.

But there's 700 islands
in that chain.

And that's like looking for
a needle in a haystack, man.

We haven't found
the U‐boat yet,

but we're certainly
in the right area

according to Roger's
descriptions.

FISHBURNE: After completing
his first dive,

Mike returns
to local headquarters

to meet up with the team.

U‐boats are being found
every day.

There's a lot of evidence
before Roger Miklos

to point to this part
of the world.

We know that during the war,

there was a lot of
U‐boat activity

in the Caribbean, because

a lot of the Allied oil
came from South America.

FISHBURNE: The Caribbean
was an unexpected hotbed

of U‐boat activity, as German
and Italian submarines

tried to prevent Great Britain
from being supplied

with oil from Venezuela.

In addition, Britain's
largest oil refinery

was on the island of Trinidad,
a U. K. colony.

From 1941 to 1945, enemy subs
took out 319 Allied ships,

in what historians call
the Battle of the Caribbean.

By 1943, the area
was under Allied control,

so why would a 1944
specialized German U‐boat

be in these waters?

Is it possible it was
on its way to South America,

laden with treasure?

MIKE:
That part of Roger's story

is very much supported by
the historical fact.

So that's what sold me,
that's what said to me,

"Mike, you're gonna have to
follow this crazy man

and see if he was
speaking the truth."

There's a U‐boat out there
and I intend

to bring it up shortly.

FISHBURNE: Mike's research
convinced him

Roger's story could indeed
be true.

‐ Looks like a nice vessel.
‐ Yeah.

‐ Hi!
‐ Come on board.

Well, thank you.
Wow, this is beautiful.

FISHBURNE: The team boards
the Explorer II,

the dive boat that will be
their home

for the next several days.

Ultimately we want to go
to the we‐‐

sort of the south bottom corner
of West Caicos, so...

All right, I think
we can work that out.

‐ No problems?
‐ No problem whatsoever.

We got a lot of gear
we gotta get on board.

‐ We should probably, uh...
‐ Yeah.

Like, have you seen
how much stuff we have?

[laughter]

FISHBURNE:
To track down the sub,

Mike and his team
will be using

state‐of‐the‐art equipment

that Miklos could not
have dreamed of back in 1981.

‐ Got it, Chris?
‐ Yeah, I'm good.

We're going out there
with everything under the sun.

I've never been
this well prepared.

Magnetometer, ROV,
side scan,

you name it, it's in our bevy
of electronic tricks.

FISHBURNE: But in the end,
it will all come down

to the trail of breadcrumbs
left by Roger Miklos himself.

MIKE: Roger has left us
with this crazy bunch

of hidden clues about
what we may or may not find.

Something tells me that this
is not gonna come easy.

We're about to find out.

You really work to get inside
Roger's head

and you think you've got him
figured out, but...

he might surprise us yet.

FISHBURNE:
Mike knows they are looking

for what Roger labeled
as a French frigate,

and they know it's
in Turks and Caicos.

But that's still
an area covering

thousands of square miles.

So the next step
is to narrow the search.

You often hear that it's a hunt
for a needle in a haystack.

In this case, we've gotta
find the haystack

before we can find the needle.

Guys, maybe we'll just
take a table

‐ and spread the chart out.
‐ Sure.

So, complete LORAN chart.

On the pad of paper
where Roger lists

a bunch of his shipwrecks,

some of those locations are
clearly latitude, longitude.

But then there's
the French frigate,

and there is this cryptic number
beside the French frigate‐‐

143228.

Right away, I went, "That's
gotta be a LORAN number,"

a system of navigation
sailors used

before there was GPS.

FISHBURNE: Used for plotting

and converting
measure data lines

to latitude and longitude,

long‐range navigation,
or LORAN, for short,

was set up by the United States
in World War II

as a special navigational aid.

Before the advent of GPS,
it was used

by ship captains for decades.

SAM: I haven't seen
one of these in a long time.

You've actually seen one?

Yeah, I'm not as young
as I look, but...

These were state‐of‐the‐art
back in Roger's day, but...

‐ We've come a long way.
‐ Nobody knows

what a LORAN chart is
anymore.

For me to try and find
his location based on LORAN

means I had to find
an old LORAN chart,

and that was not easy.

But I did find one.

I did find one chain
or one coordinate

that makes sense with
what Roger's telling us.

So, French frigate,
one LORAN line.

‐ Okay.
‐ 143228.

Come straight up this line,
we're looking for 3228.

Bingo. French frigate.

It's the only place
in the entire country

that that line crosses
the water depth

that we're looking for,

somewhere between 45
and 100‐plus feet.

When I saw "French frigate"
on the list

and I saw the bits and pieces
of the position,

I went, "That's where we go.
That's where we go first."

So there's one
of two things here‐‐

a French frigate or a U‐boat.

Like any good
treasure hunter would,

they're not going to put
a real X on a real map

on a real location.

That's not uncommon
for treasure hunters

to often code their finds,
right?

‐ To keep looters from‐‐
‐ Uh, no.

They are the sneakiest bastards
on the planet.

What they do is they give you
a piece of the truth,

and then they‐‐they‐‐they‐‐

‐ they're deceptive, right?
‐ They tease you.

They have to protect
their finds.

‐ Oh, absolutely.
‐ Yeah.

Like, if they've got something
serious to find,

they don't want
their competitor finding it.

Treasure hunters
are very territorial,

and they really hate to see

a competing boat
on the horizon.

It's every man for himself.

ROGER: Gold changes people
like you wouldn't believe.

I could tell you stories of guys
I had on my boats,

and the greed just fires off
like you can't believe.

FISHBURNE: All the secrecy
and code underscores

how little the team
really knows

about what Roger found
on that day in 1981

and where it might
actually be.

They're putting together
a puzzle

without all the pieces.

He went to a lot of trouble
to hide

whatever it is he found here.

‐ Right?
‐ Mm‐hmm.

‐ Does it make sense?
‐ It does.

Look at the torture
he put himself through.

I think he found a U‐boat.
I really believe that.

His story stayed consistent
from the time

he first discovered it
to the day he died.

‐ Exactly.
Treasure hunters can be

a bit of snake oil salesmen,
right?

They all want
to find something,

so they tell you
they found it.

But he, for his entire life,

was completely dedicated
to this.

It would be the biggest tale
on the planet, man.

But if anybody used
their head,

there ain't no way I could come
up with this bullsh‐‐

out of my head, man.

One thing about bullsh‐‐,
you can't remember it

unless you're really good.

But you can always
remember the truth.

No matter how hard you try,

you can always
remember the truth.

It always comes out
the same way twice.

SAM:
This guy's a character,

but he did dedicate
his entire life

Anybody who's truly a fraud

usually gives up
before Roger did.

Roger found a U‐boat.
I'm convinced of it.

You know, whether it's Hitler's
U‐boat full of treasure,

that remains to be seen,
but I believe in Roger.

I really‐‐evidence tells us.
History tells us.

There's a U‐boat here.

There's a lot
of what Roger says that

is plausible.

But then there's this one thing

that he claims
that is on the U‐boat,

and I just went, "Wow."

FISHBURNE: In the Caribbean
country of Turks and Caicos,

Mike Fletcher and his team
are on the hunt

for what could be a missing
Nazi U‐boat from World War II

claimed to have been discovered
40 years ago

by famed treasure hunter
Roger Miklos.

INTERVIEWER: Where is it?

It's sitting in British waters
in the Caribbean.

But you won't say
exactly where?

No, I'm trying to keep that
protected as much as I can.

FISHBURNE: After the government
of Turks and Caicos

banned him in 1981
from returning to the site

where he says he found
the U‐boat,

Roger spent
the rest of his life

keeping the sub's location
secret.

Now, after his death,
the unique personality

that was Roger Miklos
casts a long shadow

over the team's mission.

Roger Miklos has
some very significant finds

that he has discovered
over the years,

so he is
a legit treasure hunter,

but he has a lot of controversy
surrounding him.

FISHBURNE:
One of those controversies

involves a claim Roger made

about the contents
of his U‐boat.

He says his research
convinced him

that the sub was filled
with gold, paintings,

and maybe even Nazi officers
attempting to escape Germany,

and the facts do lend
credibility to Roger's theory.

Nazi subs did indeed
sail the Caribbean.

And at the end of the war,

many Nazis successfully
fled Germany

to live in South America.

But so far, there is
no evidence to support

his last,
most controversial claim.

There's this one thing

that he claims is on the U‐boat

and I just went, "Wow."

Hitler, supposedly,
to the public committed suicide.

Uh‐uh.

FISHBURNE:
It's an extraordinary statement,

but could it be true?

Could the bodies of
Adolf Hitler and Eva Braun

be entombed aboard
Roger's submarine?

He's not the only one out there
who thinks that

there might have been
some mystery and intrigue

with what actually happened
to Hitler.

FISHBURNE: Roger claimed
that meeting with Nazi hunters

and retired German officers
convinced him

that Hitler
faked his own suicide

and escaped
on a modified U‐boat.

ROGER: Hitler got away clean,
and was taken

to where the U‐boats
were waiting

and off they went.

MIKE: Do I believe Roger
found a U‐boat? Absolutely.

Do I believe that the U‐boat

was carrying gold and paintings

looted from Europe
after the war?

It's possible.

But do I think that Hitler

was onboard his U‐boat?

No.

It's obviously to me that Roger
loved a good headline.

He liked to be in front
of the news camera.

He needed the attention.

He needed to garner support
for his idea.

He needed investors' dollars.

But more critically,
he needed permits

to go back to
the Turks and Caicos,

prove to the world that he had
actually found a U‐boat.

Did Roger get a bit eccentric
over all the years

of trying to convince the world
he'd found a U‐boat?

I don't know.

Most shipwreck hunters are

a little kind of off‐base.

You become obsessed with
finding that treasure.

You become obsessed
with constantly looking.

MIKE: But the one thing
about Roger

over all those years is
that his story didn't change.

He said he found a U‐boat.

One of the nine U‐boats

ordered by Hermann Göring
at the last part of the war

in 1944 to remove high command

art objects to South America.

FISHBURNE: In 1944,
Hermann Göring

and U‐boat commander
Karl Dönitz

ordered the construction

of a technologically advanced
Nazi sub‐‐

the XVIIB,

built at the Blohm & Voss
shipyards in Hamburg.

It was faster and quieter,

designed to combat new Allied
strategies

against U‐boats in the Atlantic,

including depth charges
and convoys.

And according to Roger,
the sub he saw was branded

with a logo from
the Blohm & Voss shipyard.

Now, after months of research,
the team feels

they have made a breakthrough
in their search,

and have identified
a possible location

of what could be
the final resting place

of the mysterious Nazi U‐boat.

Roger said there is

a shipwrecked French frigate
there.

But we also know that Roger has
said that the French frigate

is really the U‐boat.

What I know is, this is where
Roger says to look.

I gotta think
we're in the right spot.

FISHBURNE:
But knowing where to look

is only half the battle.

Finding a U‐boat that has been
submerged over 70 years

is a daunting task.

There's been a lot of passage
of time, right?

Things move around
under the water.

Well, and the dangerous thing
is that

we know this thing is sitting
on a steep incline.

Once it moves,
let's say in a hurricane,

‐ if it did let loose...
‐ Yeah.

...it would plummet
into the abyss.

The ocean is a huge place
that's constantly changing,

so anything on the seabed

is gonna be affected
by that change.

Hurricanes, earthquakes,

even a tsunami.

Shipwrecks roll over,
break apart,

even fall off cliffs.

The next question is,
do we dive first

or we just go out
with the mag first?

How big of an area
do you think we need to cover?

At least 1,000 square meters
or yards.

Let's go take
the magnetometer out

and see if we get a hit,
and then,

at least we know
where to start.

Let's hope we get a huge hit.

FISHBURNE: With such
a large area to cover,

with depths hundreds of feet,

putting divers in the water
is not feasible yet.

You don't just jump in the ocean
and find a shipwreck.

The ocean is just so big,

thousands of miles
in every direction.

Imagine trying to find something

as small as a U‐boat.

FISHBURNE:
To narrow the search,

the team breaks out
the first piece of gear‐‐

Sam's trust magnetometer.

So let's get her hooked up
to the laptop.

Back in Roger's day,
the mag was just a needle

whipping up and down
on paper.

This new, sophisticated mag

will paint a chart
with magnetic hits.

You're looking for a pattern
that shows you

that hey, something's different
than the things

that are surrounding it.

‐ Hi.
‐ Hey, Captain,

you got a couple minutes?
‐ Yeah, come on in.

Great. So we're finally gonna
get

the magnetometer in the water.
Weird question, but

how slow
can we go in this boat?

‐ Can we go 4 knots?
‐ No problem.

Okay, so we're gonna run
about 4 knots

and what we're gonna try to do

is what they call
mowing the lawn.

Drive the boat in one direction
for a little while,

turn around, drive it back
in the other direction.

Certainly
if there is something

that shows up, even if
it's a small object,

we'll probably get you
to stop.

‐ Okay.
‐ So we'll communicate,

if you don't mind,
using this here.

‐ Okay.
‐ So we'll give you a call

when we're
about to get started.

‐ Does that work?
‐ Perfect.

‐ Cool.
‐ That sounds good.

SAM:
I can't wait to get there

and have a look what's
down there.

We have everything that

a shipwreck‐hunting team
could want.

We've got a magnetometer,
we've got side scan sonar,

we've got multiple ROVs
with multi‐beam sonar on 'em.

Nobody has this much equipment,

so if there's something
to be found,

I think we're gonna find it.

Hey boys, how's my maggie?

She's almost ready
for a swim.

Awesome.

‐ All ready for you.
‐ Good. GPS is hooked up.

MIKE:
Chris, if you carry that,

Sam and I will carry
the reel.

Okay, perfect.
I want to be careful

'cause there's a very delicate,
expensive

glass sensor in this thing.

I know you're gonna be
careful.

I do think Roger is credible.

Could he be incorrect?
Possibly.

But there's only one way
to find out.

We have to go and see.

We are ready to deploy the mag.

Of course we're all chasing
the "eureka" moment,

but it all begins with that
moment

when you throw out
the lines

and you're on your mission.

Watch that reel.
She's gonna pull fast.

This is a very, very,
important first step.

If there's something made of
metal down there,

we're gonna know soon.

‐ You got it?
‐ I got it.

There she goes.

FISHBURNE: Off the coast
of Turks and Caicos,

Mike, Sam, and Chris
are taking a vital step

in their search
for a sunken Nazi U‐boat.

There she goes.

FISHBURNE: They've deployed
a magnetometer

to scan for metallic objects
on the ocean floor.

SAM: As we throw the
magnetometer into the water,

it feels like all of the hard
work that we've done

over the past month,
all the logistics

to get out here is
finally coming to fruition.

All right,
slowly letting it out.

You should have signal!

Connecting.

FISHBURNE: But towing
this advanced piece of equipment

is not without its challenges.

The ever‐changing terrain
of Turks and Caicos

makes the team's mission
particularly difficult.

Turks and Caicos
is absolutely paradise,

but there are some challenges.

One side of the archipelago

is just completely filled
with rocks

and coral and it's super
dangerous for boats to get in.

FISHBURNE:
Formed by coral reefs,

the islands sit on
a foundation of soft limestone.

Centuries ago,
when ocean levels were lower,

acid rainwater collected
in pools

and over time, began to dissolve
the surrounding limestone.

The result is a topography
of ridges, fissures,

sinkholes, and caverns

many of which have never
been explored.

MIKE: Normally you look
for a shipwreck,

it's gonna be obvious.

It's laying there
on the ocean floor.

But imagine how hard it is
to find a U‐boat

when it's underground.

This just happens to be
underwater underground.

Are you good there, Chris?

Yeah, I'm good.
How's it looking up there?

It's good. I's marking.

Magnetometer work is long
and tedious.

You spend a lot of time
in front of a screen.

So just let it out
nice and slow.

That's good, Chris.

Just keep letting it out
slow like that.

Still going.

SAM: We're gonna see a graph
that's coming up

on our computer screen,

and we're looking for
a big blip.

Whoa, hang on. We got something,
something here.

There's something.
There we go.

‐ Whoa.
‐ We got a hit?

‐We did get a little hit there.
‐ Yeah.

Like, look at all that.

Tons of stuff coming on here.

So we‐‐we hit something.

Now, was it U‐boat‐sized?

The good news is that
we are getting some hits.

They're not submarine‐sized
hits.

But we are showing some
magnetic anomaly.

So, there's something here
to dive.

But we haven't really hit
our sweet spot yet,

the spot that Roger told us
should be the French frigate.

If it's there and we've
crossed by it,

we'll get a huge hit.

FISHBURNE: As Mike and the crew
get closer

to the sunken U‐boat location,

the one constant is
the unpredictable nature

of the open seas.

Chris, you notice that
as we're coming more south,

‐ there's more sea running.
‐ Yeah.

Yeah, we're getting into
some chop here.

‐ It's gonna get rough.
‐ Yeah.

SAM: Operating the magnetometer

in even small waves
is difficult,

and now we're in
really rough seas

and we really have to monitor
the mag's buffer to the bottom.

It looks like the weather is
turning on us a little bit.

The seas have picked up.

It's not as nice and flat calm
as it was when we started.

FISHBURNE: Extending the cable
helps to balance out

the variations
in the water depth

caused by sudden swells,

but that comes with a risk.

A longer tether makes it
much more difficult

to make quick adjustments,
making it vitally important

that they maintain
enough speed

to keep the magnetometer
off the sea floor.

Hey, Chris, Chris!

We're not going fast enough
to hold the mag up.

Captain's gotta pick up the
speed

or you gotta roll tether
like now.

'Cause I got 18 feet of depth
and 20 feet of bottom.

We're gonna have you pick
up the speed

by one knot, please.

So we can go five.

CAPTAIN ON RADIO:
I'll go five.

Very good.
Five would be great. Thanks.

FISHBURNE: With the ship's
speed adjusted,

the magnetometer's sweep
resumes.

Turning you
to starboard slowly.

FISHBURNE: So far,
none of the data suggests

that there is a U‐boat
in the area,

but the team holds out hope.

MIKE: We're not getting a hit,
but I'm still convinced

this could be the spot.

We're gonna make
one more pass

across what I call
the sweet spot,

and, uh, hopefully we're gonna
see this great big change

in magnetic field.

Guys, I think I got a hit.

Are you serious?

What do you got?

SAM:
I think that could be it.

Oh, my God.

FISHBURNE:
In Turks and Caicos,

the team believes
they're closing in

on what could be
a lost Nazi U‐boat

when Sam gets some promising
data from the magnetometer.

I think I got a hit.

‐ What?
‐ Check this out right now!

‐ Come up, quick!
‐ Are you serious?

When you find something,
when you get that hit,

you can feel the‐‐
you can feel the excitement

in everybody.

What do you got?

All right, check this out.
So this is where

it starts to drop on the clip
a little bit...

Oh, yeah, there it is.

And then there's
the classic S.

Oh, my God.

Okay, look where we are, too.

This is pretty close
to the location.

SAM:
I think that could be it.

Getting a hit
on the magnetometer,

this means we've got
an indication of metal,

and it's exactly in the area

where Roger tells us to look
for the French frigate.

FISHBURNE:
But a hit doesn't meant

it's a submarine yet.

Determining that will require
eyes on the sea floor.

The magnetometer is not like
a sonar or a camera.

It doesn't draw you a picture.

It's just going to give you
an indication

that there is something
different than normal,

and it happens to be metallic.

MIKE: We don't know
what's there.

It could be an old car,

a sunken ship that
we're not looking for,

and we gotta find out what
that iron is that's down there.

FISHBURNE: The next step is
to put divers in the water.

If there's something big there,

I'm ready to jump in
and just swim down

and see what it is.

FISHBURNE: But once again,

the weather refuses
to cooperate.

Rough seas pick up and
with sunset on the horizon,

the team makes
a difficult decision.

As much as we want to just
jump in the water and dive,

it's pretty choppy,
so we're gonna pull the mag,

we're gonna wait for it
to calm down.

Maybe tomorrow, we'll do
that first dive then.

FISHBURNE: The next morning,
in calmer seas,

Mike and Chris decide it's safe
to prep for the dive.

Can you tuck that in, too,
Chris?

Yep.

I couldn't hold back Mike and
Chris for a moment longer.

Once we got that hit
on the magnetometer,

they needed to go in the water.

FISHBURNE: The magnetometer
has given Chris and Mike

the area to explore,
but it's by no means precise.

They have no idea what kind
of terrain awaits them.

Just because there is
something metal down there

doesn't mean it will be
easy to find.

U‐boats were built to dive
to great depths,

both to evade detection
and to hunt their own prey.

It's possible the sub
Roger says he saw,

partially submerged in a cave,

was there playing possum

and then was unable to surface

or that it was hit and sunk.

Diving in caves and in areas

like the geography
that creates caves

is a step beyond
the regular dive.

You're in a very unusual
underwater environment

that's not like diving
in a river or lake.

It's totally unique.
It is this sense of adventure

that you can't imagine.

The sense of awe that no one

has been in
that particular cave ever

in the history of mankind
on the planet.

There's a lot of things
about diving shipwrecks,

especially in low vis,
that's extremely dangerous.

FISHBURNE: For Roger,
it was an accident

several decades ago
that changed his life.

I don't do the diving anymore.

I did the diving
for 38 solid years.

I damaged my heart.

I had bought a brand‐new
Scubapro tank.

But I went in
and we were down at 80 feet.

All of a sudden on an exhale,

the line on the tank
blew off.

I thought I was dead.

They got me out of the water

and they brought me in
to Key West

where I was in a coma
for seven days.

And I've got
ventricular "fliberation"

on the lower part of my heart.

FISHBURNE:
It's the kind of story

that stays with
every deep water diver.

But when there's a potentially
historic discovery

on the line, the rewards
outweigh the risks.

MIKE ON RADIO:
Radio check, 1‐2‐3.

SAM:
Five over five.

MIKE: It's a big, big deal
to find a U‐boat.

And it's that spark of history
and real adventure

that drew me to U‐boats,
specifically.

Although I'm not after
the alleged billions

or millions of dollars
in the U‐boat.

The treasure is history.

The treasure is in the hunt.

The treasure is in finding
that item that's lost

that no one else has been
successful at finding.

[beep]

Sam to Chris.
If you read, what's your depth?

Give me a depth check.

This is a really, really
craggy seabed.

It's not like anything
you'd normally see.

With big overhangs and
sharp drop‐offs and gullies.

The way Mike and I work
is he goes down

with his handheld
metal detector,

and he starts scanning
the area.

But everything's covered
in sand or coral

and you could have a U‐boat
that's been down there

for quite a long time
completely covered

and you could be looking at it
with your eyes

and swim over it
and not realize

that you've just swam
over a U‐boat.

SAM: We see shifting of sands.

It could one day
be completely covered,

six months, be open,
and then covered back up again.

So, we're really looking
for small artifacts,

indications that something
might have been there

at one time,
and then pathways of debris

that might lead us
to the mothership.

MIKE: With the handheld
metal detector,

if there is something
even as small as a paper clip,

I'm gonna know it's there,
even though I can't see it.

[beep]

SAM: Chris, just wondering
what you're seeing down there.

What's the bottom conditions?

Does it look like somewhere
a U‐boat might have wrecked?

FISHBURNE: It's a time‐consuming
and methodical search,

and Mike and Chris
make several trips

back to the surface
for more air.

Anything of interest
down there?

Roger that.
Keep me updated.

♪

FISHBURNE: Then, something
catches Mike's eye.

SAM: Amazing.
What do you got?

[radio static]

Surface to Mike.
Do you read, over?

[radio static]

It's something.

Don't leave me hanging, Chris.
The anticipation's killing me.

What do you got?

FISHBURNE: Following
the piecemeal clues

Roger left behind,
Mike and his team believe

they may have found
a promising lead.

Now the team's instruments

have detected iron
on the sea floor...

and Mike and Chris
dive down to investigate.

What do you got?

Sam, I've got something here.

MIKE: As we're following
this metal trail,

we come across
a metal pipe flange.

To me, this is
a pressure fitting.

This is exactly
the kind of thing

that you would use
in the construction

of a submarine.

Most of the metal pieces
are hard to identify,

except for one piece.

And that piece could be
a very significant find.

And it appears to be a flange,
or pressure fitting for a sub.

FISHBURNE: Sub flanges are used
to connect pipes,

valves, and equipment

to provide
a pressurized seal.

When compromised
by a catastrophic disaster

onboard a U‐boat sub,

this would be the type
of debris one would find.

We're finding these bits
and pieces of iron

that shouldn't be there.

[beep]

It could lead us
to a shipwreck,

but hopefully our U‐boat.

[beeping]

CHRIS: Cameras are extremely
important

when you're searching
for shipwrecks.

There are legal reasons

that would like to have
your shipwreck hunt documented

to prove that you are the one
that found it,

to prove that you
also didn't do anything illegal.

FISHBURNE: Shipwreck
and treasure hunting

has been around centuries.

The discovery of an old wreck

can be worth
millions of dollars.

However, finding treasure
or valuable property

is not always as simple
as finders keepers.

A key question is whether
the discovery of goods

is deemed salvage
or treasure hunting.

A salvage refers
to when someone

sees property drifting,
lost, or abandoned at sea.

Under international conventions,

the salvager is required
to return the found goods

to the original owner
in return for a reward.

Treasure hunting
typically means

exploration aimed
at unearthing antiquities

and other valuables
from shipwrecks

for financial gain.

If the find lies
in international waters

and there's no one
to claim ownership,

the finder is probably
in the clear to keep it.

However, because of
the ambiguity,

most countries
have enacted laws

to establish
government ownership

for the majority of shipwrecks
found in their waters.

Just because you've found
a shipwreck, or even pieces

that you think are part
of a shipwreck,

if you don't have a permit,
you can't remove it.

FISHBURNE: Treasure hunters
who ignore these rules

often find themselves
in trouble with the law.

Not having the correct permit

is what got Roger Miklos banned

from ever returning
to Turks and Caicos.

That's where Roger
seemed to run amok

of the Turks and Caicos
government.

They claim he didn't
take out the right permits

when he recovered an anchor.

FISHBURNE: Photography
is the best way

for divers
to stake their claim

when they find a wreck.

With so much more
potentially at stake,

it's not uncommon for
unscrupulous treasure hunters

to swoop in.

There's always somebody
after your discovery

who want to tell the public
they found it first,

they have rights.

It's a no‐holds‐barred
fight to the death

when it comes to shipwrecks,

and especially shipwrecks
with treasure.

I found a very important
historical wreck,

and treasure hunters
learned that I'd found it.

It led to this really
precedent‐setting court battle,

trying to determine
who had found it first

and who had rights.

As it turned out,
it was my photographic evidence

that proved my case.

FISHBURNE: It's a lesson
Roger Miklos

had to learn the hard way.

MIKE: Roger claims
that he took photographs

of his U‐boat.

He also claims that
all of those photographs

were lost when
he was run off the island.

If just one of those photographs
still existed,

this whole story
would be very different.

FISHBURNE: Once Mike and Chris
have documented their find,

they begin to follow
the trail of parts,

hoping that it will lead
to the missing U‐boat.

So, we followed the trail
of bits and shards of metal

until it disappeared
into the abyss.

It leads you to wonder,

was there a U‐boat here
that just slid off the edge

and dumped into the abyss?

When you look at the seabed,

you can see a groove,
almost a trough

that takes you all the way
to the edge of the wall

and then drops off
into about 3,000 feet of water.

Everything else
is covered in coral.

Everything else looks like
you would expect.

But this trough
is kind of almost boat‐shaped.

You could imagine this U‐boat
sitting there on the edge,

and over time,
it's very likely

that a storm could have
pushed that off the edge.

Down to 3,000 feet of water?
We don't know.

Roger talks about the sub
being inside of a cave

or partially inside of a cave.

But could that be Roger

trying to throw us off
the scent again?

We need to find out.

FISHBURNE: Mike and Chris
are in the deep waters

off Turks and Caicos

in search of an underwater cave,

attempting to get a visual
of the Nazi U‐boat

that Roger described.

MIKE: There really was
the right incline,

as Roger described
some 45 feet down to 100‐plus.

CHRIS: Mike and I reached
our limits.

We got down about 130 feet
and realized

that we're over
almost like an abyss,

and we can't dive down there.

FISHBURNE: Mike and Chris
have no choice

but to give up
and return to the boat.

MIKE: Now that we've found
the shards in this gulley,

I just want to keep
going down,

get into deeper water,
see if there's more shards

and more evidence of something
that was on the shelf.

We got to the edge,
we looked over the edge.

Everything that Roger describes,

the valley leading down,
the incline, it all matches.

It's time for you to send
this thing down there

and look over the edge.

If the dive is beyond 100
and, say, 65, or 180 feet,

then it's time to bring in
Sam with the ROV.

She can go places
we can't go as divers.

CHRIS: Sam McDonald
has her own company,

Deep Trekker, who makes
amazing underwater ROVs

that are really,
really important

for the kind of stuff
that we're doing.

The ROVs allow us to look

into deep, dark spaces

that divers can't go into,

and go to those deeper depths

that the divers can't reach.

FISHBURNE: ROVs have helped
locate and document

some of the world's
most famous shipwrecks.

ROVs are being used
in shipwreck hunting

every day now.

ROV technology was used

to take some of the first looks
at the Titanic,

as well as a famous
whaling ship from 1902

called the Nova Zembla.

And we even got to go inside

of the USS Arizona
for the first time,

and got eyes
on some of the damage

and some of the items
and artifacts

that are still inside
of that ship.

FISHBURNE: ROVs also helped
locate two vessels

from one of the great tragedies

in the age
of Victorian exploration,

the mysterious disappearance

of Britain's
Franklin expedition,

sent in 1845 to map Canada's

supposed Northwest passage
through the Arctic.

Though many missions were sent
to find the doomed ships,

their location remained
a mystery until 2014,

when ROVs found the vessels
on the ocean floor.

And of course,
the great thing about an ROV

is it's not limited like divers
to time or depth.

You can send an ROV
to the deepest spot

in the oceans.

And that has changed
the whole game.

They'll go into spots
that you wouldn't want to go

as a human,
because there's a good chance

you won't ever come back.

And I can tell you,
there's a lot of shipwrecks

with ROVs trapped in them
that aren't coming home either.

So, this is the Revolution.

So, it's got six thrusters
on it,

so it's gonna hold
nice and steady.

But for searching,
we've got the 4K HD camera,

and then the multibeam
forward‐facing sonar.

ROGER:
Here's my original drawing,

the way that thing is set.

She's up more at the ceiling,

then that island
comes clear up here,

because I had a hell of a time
getting around

to the front of the gun.

SAM: Roger tells us
that this U‐boat

is on a cliff
maybe partially submerged

inside of a cave.

ROGER: And it's lodged.

It's even lodged farther up
than the way my drawing is.

I‐‐ you know,
I did this so quick.

SAM: We're going back
a lot of years here.

Things move around.

We know that there's been
a few hurricanes out here.

An object as a large
as a U‐boat

could be pushed
by storms, hurricanes,

surges, and push it
right over that edge.

I saw the two
back propeller blades,

they're highly polished
from going in the sand,

up and down in the sand.

Even Roger tells us,

it's going up and down,
and up and down.

So, it's already got some
buoyancy. So, it's tender.

Now, there's decades have
passed since Roger was here.

Did it, like,
go in a hurricane,

slide down that slope,
and just...

drop over the edge?
We can't know.

We'll cruise down that cliff
and look for a cave,

and maybe there's a U‐boat
hanging out of it.

You ready to get this
in the water?

I wanna go find a U‐boat.

‐ Come on, let's fly it.
‐ Let's do this thing.

Let me know if you guys
need a hand here.

Looks like you got it.

All right, let's do this!
Let's go!

Let's go fishing for U‐boats!

FISHBURNE: The crew
now deploys the ROV,

hoping it can pinpoint
the location

of the missing U‐boat.

CHRIS: We're descending.

FISHBURNE: And ultimately
help them find the treasure

that's been lost at sea
for decades.

Still going out.

FISHBURNE: Sam steers the rover

towards the edge
of the underwater cliff.

We're about 12 meters down?

‐ Twenty meters.
‐ Twenty meters down.

SAM: Descending. All right,

so if you feel tight
on that tether, Mike.

‐ It is.
‐ Just keep paying out,

'cause I'm doing down.

MIKE: Going down.

ROVs, because they're providing
information in real time,

have to have a tether
to send that data back.

That can be a challenge.

If you're on a swinging boat,
there's a chance

of the tether getting
caught up on things.

Plus, you're limited
to how much tether you've got.

You can only go as far
and as deep

as that tether
allows you to go.

CHRIS: So, you're working
really hard to avoid

all hang‐ups, and of course,
damaging the coral.

‐ Yeah.
‐ Yeah.

Yeah, we don't want to be,

you know, ruin anything that‐‐

‐ No. No.
‐ That nature made us.

I‐‐I would say
we're probably moving

like over 200 degrees
on this mooring.

So, I don't know, Sam,
are you okay with this?

SAM: We're on a big boat.

We've only got a bow anchor
on a 100‐foot ship.

It's gonna swing
150 feet one way,

150 feet the other way.

This is a challenge.

FISHBURNE:
The crew can't afford

for the rover's umbilical
to become entangled

in the boat's propeller,
or even worse,

on the coral of the sea floor.

Sam guides the rover
to the area

where Mike and Chris
found the metal debris.

Yeah, yeah, no.
A little bit over to the right.

‐ That's it, that's it.
‐ Okay, yeah, there it is.

‐ Oh, very cool.
‐ Yeah.

MIKE: Now, just sail her
down that gully.

CHRIS: Yeah, follow that down.
Yeah, that‐‐

MIKE: Chris, stop her
when she gets

to where we found
the chunks of iron.

Yeah, I'm watching for it.

It's right around...

Yeah, right around there.
Right around there.

That's where Mike‐‐
that's where Mike got that hit.

‐ Okay.
MIKE: Just a little more

‐ to port.
‐ Okay.

Whoa, now, see how deep
an blue that is?

That's the abyss.

That's where Chris and I
were not gonna go.

Okay, yeah, look here.
I got like a glowy

on the‐‐ on the sonar there.

‐ Oh yeah.
‐ Yeah, look at‐‐

look at the formation.

SAM: So, the ROV goes down,

it sees the geography
that Mike and Chris described.

It sees the bits of metal

that indicate something
would be there,

and then off into the abyss,
we see the big cliff.

Wow, this boat is swinging
all over the place.

‐ Yeah.
‐ Yeah.

I think it's gonna be
too difficult

to keep doing it from
the back of this boat.

SAM: See this here?
CHRIS: Yeah.

SAM: I would like to get
a visual on that.

CHRIS: Okay.
SAM: So, what is that, right?

CHRIS: Yeah.
SAM: It's certainly different

than everything else we see.

‐ See this line?
‐ Yeah, you see...

So, it's making like a,
you know.

There's no straight lines
in nature, right?

Whoa, we're really swinging,
guys.

All right, guys,
I think that it's probably best

to pull this one up.

Let's go check out
that one marking

that I got on the sonar.

I've taken the GPS location

that we want to go to
on the Zodiac,

and then drop
the little one in

‐ and see what we can find.
‐ Okay.

Okay, hauling it in.

FISHBURNE: Mike and his team
are searching the waters

of Turks and Caicos

for a highly specialized
Nazi U‐boat,

one of only nine commissioned
in 1944.

Roger Miklos claimed
he saw it here in 1981,

and that it's carrying what
could be billions

in gold, treasure, and art.

The team wasn't able
to dive deep enough,

so Sam is using an ROV
to assist the search

at greater depths.

But the constant sway
of the current

is causing the boat
to swing wildly.

Whoa! We're really swinging,
guys.

FISHBURNE: And the ROV
is in danger

of getting snagged
on the sea floor.

Sam decides it's time to move
the search to a smaller boat,

the ship's Zodiac.

Okay, let's take this one out.

‐ This is the DTG3.
‐ I like this little guy.

Little wee guy.

Great for boats
just like this.

All right, send that‐‐

You just throw the Deep Trekker
in like that?

Just manhandled.

That's no way to treat
your baby.

No way to treat your baby.

MIKE: I was really happy
to just use the small Zodiac

and not have to contend
with anything

swinging or moving.
It worked really a lot better.

As I got deeper, the marine
life got less and less,

and it just became gray rocks
as I went down the wall.

It just got darker and darker.

FISHBURNE: But even with
the added stability,

the rover is quickly nearing
the end of its umbilical.

CHRIS:
About how deep are we now?

SAM: About 275 meters.

CHRIS:
Can we go much further?

‐ We got like 25 left.
‐ [groans]

SAM: It doesn't look like
there's a bottom here.

MIKE: Can you see‐‐reach out
with the sonar?

Is there anything?

SAM: You know what?
I have the sonar range

at 50 meters, and it's not even
picking up the sea floor.

‐ MIKE: Wow.
‐ SAM: I point that sonar

straight down, nothing.

SAM: So I flew the ROV
to the edge of the cliff,

I turned around to face it,

and I started to descend
straight down the cliff.

So, in the first probably
300 feet,

we saw corals, we saw different
marine life on the wall.

I picked up on the sonar

a bit of an overhang,
almost a cliff there

and so I went a little bit
to the starboard side

and had a look,
had the camera out.

Didn't look like what‐‐
you know,

a place where a U‐boat
could really hide,

so I continued to descend.

I'm gonna be honest‐‐
this is as deep

as I've personally ever
taken this stuff.

MIKE: See any more evidence
of pieces or chunks

‐ as you went off the cliff?
‐ SAM: You know, sort of, maybe.

There was an area where it
just sort of looked...

beaten up, like something
may have scratched it,

for lack
of a better description.

But if it did that,
it wasn't a smooth journey,

that's for sure.

So a lot of the places
in the Turks and Caicos

where Roger's U‐boat could be
are either too deep

or in very enclosed spaces.

FISHBURNE: The rover follows
a trail of debris

down the abyss,
as Mike, Chris, and Sam

hold out hope that the
trail of debris and scratches

will end in the big discovery
of Roger's U‐boat.

SAM: That's the end, boys.
That's it.

I got nothing left.

Like any good treasure hunt,
we hit another roadblock.

SAM:
I can't definitively say.

If there was a U‐boat there,

it would be on the bottom,
and I just couldn't get there.

I think we can call this one
checked out, truth.

Let's pack it up
and head back to the boat.

CHRIS: Still so much
more depth to get down.

I think we need to try
to identify

the pieces that we found,

and hopefully that gives us
enough reason

to come back with more tether
and better equipment.

Good to go.

FISHBURNE:
Mike, Sam, and Chris

make their way back
to the boat.

After storing their gear,
they reconvene

to discuss the state
of their mission.

Let's look at
what we've learned.

There may be something
yet beyond

what Deep Trekker
could reach today.

‐ Yes.
‐ We have these bits of iron

that may be indicative
of a U‐boat,

this round flange
of some sort, right?

‐ SAM: Yeah.
‐ MIKE: That's gonna be

some sort of high‐pressure
piping flange.

Submarines are full of that.

According to Roger,
this was like

a submarine freighter, right?

Heading to South America
with the spoils of World War II.

Roger was on the trail
of a U‐boat,

and he was convinced that
it carried billions of dollars

worth of gold bullion
and treasure.

So now as we look in deeper
and deeper water

and more out‐of‐the‐way
places

like the Turks and Caicos,

it's a big, big deal
to find a U‐boat.

Guys, it's time to leave here.
We gotta move on.

Right?
'Cause we just don't know.

But let's regroup,
let's talk to the experts.

Let's just be determined to
be openminded,

‐ get more information.
‐ Agreed.

‐ Let's pack it up.
‐ Okay. Let's do it.

FISHBURNE: Shortly after
the team completed

their underwater search,
their expedition was shut down

due to the COVID‐19 pandemic.

MIKE:
We just learned that

the entire project's
been shut down...

due to COVID.

I just... [sighs]

hate the thoughts of
going home right now...

and truly believe that Roger's
U‐boat is out there

waiting for us to find.

FISHBURNE: Two months later,
they regrouped

at home base to hear intel
from U‐boat expert,

Rob Carmichael.

MIKE: Sam was able to track down
a U‐boat expert,

a guy named Rob Carmichael.

FISHBURNE: In 2016,

divers located a mysterious ship
resting in darkness

in about 700 feet of water.

Forty‐four sailors
were entombed within it.

It was a Nazi submarine.

U‐576.

It was sunk in 1942.

Look at that.

‐ Topside!
‐ Ha ha!

We got a visual.

FISHBURNE: In World War II,

the greatest concentration
of U‐boat attacks on America

happened off of
North Carolina's outer banks

where dozens of ships
passed daily.

The U. S. military didn't want
people to worry,

so news reports of enemy boats
near the coast

were classified for
national security reasons.

The discovery of U‐576
also revealed a submarine

that was mysteriously intact.
This suggests the vessel

may have dove to the bottom
intentionally

to play possum but somehow
couldn't surface again,

killing
all crew members inside.

Roger claims the U‐boat
he found was also intact.

Is it possible
that the U‐boat Roger found

may have tried a similar trick
in Turks and Caicos

to avoid Allied detection

only to meet a perilous fate?

Hey Robert,
it's good to see you.

My pleasure.
Good to see you today.

So for the sake of everyone
on the call,

Robert Carmichael
is a friend of mine

who is well‐versed
on all things ocean,

and so we're hoping that,
Robert, you can provide us

with some expertise on
the things that we've found.

We've sent you a few
photographs, Robert.

Metal objects that we found
with the eye

and with our handheld
metal detector.

We did, however,
get a large magnetic hit.

These little pieces clearly
are not

part of the mag hit
that we got.

They seem to be pieces
scattered on a trail

leading down and dropping
over into the abyss

into deep water.

The photo that I'd most
like you to look at first

would be the one
that I call the flange.

ROB: Yeah, it def‐‐
definitely looks like a flange.

But, uh, you know...

what does that flange

seem to be mounted to
or part of?

This was just lying loose,
Robert, on the seabed.

To me this could be part of
a high‐pressure pressure hull,

but...that's beyond
my expertise.

Well, I think you could say
it's pretty certain

that it's part of a pressure
system of some sort.

Does it have the appearance
of some catastrophic failure?

'Cause if that flange
was all by itself,

and it was part of
a pressure system,

and something
catastrophically failed,

maybe‐‐
maybe that would explain.

why this flange component's

not attached to its pipe member.

The history of what it is
we're researching

has no affiliation
with an explosion

or for that matter,
a catastrophic event.

But in a storm event,
like a hurricane

where everything can be
turned upside down,

who could say?

Oh, boy, I understand that.

We just got back from
three trips to the Bahamas

right following
that gigantic hurricane

that went up the middle
of the Atlantic,

that lasted for so long.

It was 550 miles in diameter,

and we saw the Gulf Stream
flowing backwards for...

‐ Wow.
‐ ...uh, 10 days.

And it just moved a lot
of the South Atlantic ocean

to the North Atlantic ocean.

‐ SAM: Wow.
‐ MIKE: The other images

are even less definitive.

So again, tough one.

But that's the next one
I'd like you to comment on

‐ if you could.
‐ Yeah.

Not‐‐not enough to tell me
anything.

You were there in person,
so did it, uh,

feel like heavy metal
or what was it?

Well, it is definitely
iron or metal‐based.

It triggered
the handheld metal detector.

It was quite corroded.

‐ Quite disintegrated.
‐ Yeah, like it's oxidized

as if it has a really high
iron or steel content.

I know they're just little
obscure pieces.

If there's some other
compelling evidence

that would lead you to devote
resources and time

to that site, I would say
go back and try it again.

But based on the evidence and
the imagery I just saw,

there's nothing there that says
that's related to a U‐boat.

As far as I can tell,
or any significant,

reason to keep spending
resources in that area.

Time to move on.

‐ Time to move on.
‐ Thank you.

Bye for now.

I think Robert has pretty much
told us

this is not a great indication
of a U‐boat.

Yeah. When Robert was talking
about the hurricanes

and the type of damage
they cause‐‐

you know, the reversal
of the currents underneath,

the type of changes
to the sea floor that he saw,

it really struck me because
we didn't see any of that.

We did a lot of survey
of that cliff edge there,

and I didn't see anything
in the bathymetry

that would show me that
there'd been major damage,

especially the type of damage

you would think to rip
a flange off a U‐boat

or that U‐boat
careening over the edge.

I just didn't see
any of that.

I think it's time to move on.

Okay, so basically Robert
said move on,

Sam, you're saying move on.

I'm reluctantly saying
move on.

‐ Just move on.
‐ No, it makes sense.

Sounds good, Mike.

FISHBURNE:
The magnetometer hit proved

that there was something big
at the bottom of that abyss.

But the team is still perplexed
on exactly what showed up

on that magnetometer hit.

Roger was masterful
at keeping everyone at bay

on the exact location
of the Nazi U‐boat.

But that just pushed the crew
into more speculation.

I know where that site was,

where the average person
ain't got a clue.

Nobody gonna discover this.

MIKE: So for now, we're
still left with a mystery

of the missing U‐boat.

And I'm wondering if Roger
isn't up there...

laughing down at all of us.

FISHBURNE: Mike is back
to square one

with no idea where
to turn next.

MIKE: At this point, I figured
we were out of options.

We're at a dead end.

Then I got an email
from Jon Christiansen

who was not only
Roger's trusted friend,

but he was Roger's boat captain.

And he was there with Roger
in 1981

when all this went down.

This is Capt. Jon Christiansen,

captain of the Heather Glynn.

I have been a ship captain
for over 40 years,

and I was very fortunate

to be in the right place
at the right time

to meet Roger Miklos in 1981
in the Turks and Caicos.

MIKE: You can imagine
how important it is

to hear what he's got to say.

Mike, it's Jon Christiansen.
How you doing, sir?

Jon, you have no idea how glad
I am to hear from you.

I understand that you've been
very involved with Roger

looking for this submarine
that he claims

to have located
way back in the day.

MIKE: Yeah, I have.
I think it's amazing

that you were
the captain of his boat.

He found this U‐boat,
and he managed

to keep that a secret
even from you.

Yeah, he kept it a secret
from a lot of people.

Roger said, "You know,
the next thing we're gonna do,

we're gonna go find
my submarine."

And that's when I started with,

"Well, tell me about
this submarine and where is it?"

He wouldn't answer it.
He would, you know,

just say, you know,
"I don't know."

I have got the logbook
for the, uh,

for the Heather right here.

MIKE: Amazing. Wow.

Be more than happy to share
the logbooks. I can, uh‐‐

You're willing to share
you logbooks with us?

FISHBURNE: After meeting with
U‐boat expert Rob Carmichael,

the team has decided to move on
from West Caicos.

But now, Jon Christiansen,
Roger's shipmate

and captain on the Heather,
the ship that made

that infamous trip
to Turks and Caicos,

offered up his ship's logbook.

This logbook could be
the missing piece to the puzzle.

I was blown away to think that

Jon would offer up
his logbook.

This is a great piece
of the puzzle.

FISHBURNE:
Jon and Roger spent six weeks

sailing around
Turks and Caicos.

Everywhere they went was
documented in Jon's logbook.

JON: We were down there
surveying different areas,

looking at different wrecks.

We dove all around
all the Caicos islands.

We dove South Caicos,
we dove North Caicos.

We dove Providenciales,
Grand Turk.

I have got the logbook
for the Heather right here.

Amazing.

That ended up with Roger
down in the Turks and Caicos.

And if that's
your logbook,

you had to have kept really
detailed records

‐ about day‐to‐day activity?
‐ Absolutely. Yes sir. Yes.

Be more than happy
to share the logbooks. I can‐‐

You're willing to share
your logbooks with us?

Yes. Yes.

MIKE: This is the piece
of evidence

that puts Roger
in the location.

There's a witness.

This is really, really critical

to solving this puzzle.

I think this is just
the beginning of

what could be a great
adventure together.

I can't thank you enough.

This is not something
you see every day

in the business
of treasure hunting.

I wish it didn't take
all these many years

and Roger passing away
that we're all gonna try

to find‐‐to finally make
this come to fruition for him.

Well, it's a fascinating story

that's only just started
for me.

And it's continuing for me,
so I look forward to it,

whatever I can do.

These are quite literally
they LORAN coordinates

and the dive‐‐different
dive sites that we dove on

for this extended period
of time.

MIKE: Up to now,
our entire search

has been focused on West Caicos.

But this logbook,
it's sending us off

to East Caicos.

Two totally different
parts of the country.

And even though
it's a small country,

the two places are
as far apart as you can get.

JON: East Caicos
and even Grand Turk

it is very deep water

that are ringed by, you know,
ledges that are...

Oh, boy, I tell you,
they drop off 200‐300 feet.

Now, could there be
a, you know, a ledge

big enough where
a deep‐water German U‐boat

could actually get up
underneath this ledge and hide?

It's absolutely possible.
Absolutely possible.

Certainly the geography
matches perfectly

to what Roger tells us
to look for.

We're way more likely
to find a cave in East Caicos.

I ain't giving the latitude
and longitude

or GPS readings on her.
You think I'm crazy?

I can't risk‐‐I've been
protecting that thing

ever since I found it.

JON: He was protecting
what he knew.

Submarine came up,
and I said,

"I know you can't tell me
where it is,

"but tell me about
the geography around.

Where is it that you saw this?"

He said "It's
a horseshoe‐shaped island

and it's down here somewhere."

And he was very vague
about that.

And it could be that Roger
was simply

throwing me off the scent.

But I do have one area in mind
that I think,

based on discussions
with Roger, again, you know‐‐

a horseshoe‐shaped island.

That‐‐I've got a pretty good
idea what he was referring to.

MIKE:
Everything's adding up.

I've gotta call the team.
This hunt is back on.

Hey, guys.
Just got a very important

bit of information for you.

Out of the blue,
I get a phone call

from Jon Christiansen.

Roger's boat captain

back in the infamous
1981 survey.

Believe it or not,
Jon's heard about us,

heard about our search.

He sent us his logbook.

Really?

What, from
the original expedition?

Yeah. Every time they went to
a new location,

he fixed the coordinate and
wrote it in his book.

No way.

And when you put
those locations together,

I come up with a new search
area‐‐East Caicos.

So not in West Caicos
where we were before at all.

A totally new part
of the country.

Pack your bags.
We're going back to the islands.

Amazing.

Looks like I'm gonna have
to clear my schedule again.

[laughs] But you're in, right?

This has already been an
adventure

full of twists and turns,

so I'm glad to get going again.

Okay.

Way to go, guys.

When I get this logbook,
it could very easily lead us

to Roger's U‐boat.

It's telling me this search
is a long way from over.

This is a find of a find
of a lifetime.

It beats Tutankhamun
all to hell.

There ain't nobody gonna find
anything better than that.

It's been missing
for 72 friggin' years.

MIKE: This U‐boat was
Roger's life's work.

It must've been tremendously
frustrating for him.

Maybe now we can help him
fulfill that destiny

and prove once and for all

whether Roger actually did
find a U‐boat.

For 40 years, the location
of Roger Miklos's U‐boat

has remained a mystery.

Now, Mike Fletcher is
one step closer

to solving that puzzle.

And maybe someday soon,
Roger's lifelong dream

of raising his U‐boat
will finally be realized,

and the world will discover
what's really inside.

I'm Laurence Fishburne.

of "History's
Greatest Mysteries."
