THE MAN WHO DEPLOYS THE U‐BOATS
IS KARL DÖNITZ‐‐

HITLER'S MASTERMIND

Milner: I THINK THE BEST WAY
TO UNDERSTAND KARL DÖNITZ

IS HE'S A CONSUMMATE
PROFESSIONAL SUBMARINER.

YOU'VE GOT TO BE THINKING

Narrator:
DÖNITZ USES NAVAL INTELLIGENCE

TO ASSIGN THE FEW SUBMARINES
HE HAS TO LOCATE SHIPS.

Grove: THERE ARE NOT
MANY U‐BOATS AT SEA

AT THIS STAGE OF THE WAR.

THE GERMANS HAVE HAD TO MAKE
CHOICES IN THEIR WAR PRODUCTION,

AND U‐BOATS WERE NOT ONE
OF THOSE CHOICES

BECAUSE OF COURSE THEY WERE
PLANNING TO FIGHT ON LAND,

FIRST IN THE WEST
AND THEN IN THE EAST.

Jentzsch: SO HE HAD TO USE
THESE SMALL NUMBERS,

AND THE ONLY THING HE COULD DO
IS TO SPREAD THEM OVER THE OCEAN

LIKE BUTTER ON A VERY BIG
SHEET OF BREAD.

THEREFORE, IN THE FIRST STAGES
OF THE SECOND WORLD WAR,

THEY WERE STILL FIGHTING
LIKE IN THE FIRST WORLD WAR,

Jentzsch:
KRETSCHMER WAS SITTING VERY CALM

A CRIMINAL NOVEL.

ON THE HYDROACOUSTICS,

KASSEL, WAS LOOKING AT HIM,

Narrator:
AVOIDING UNDERWATER DETECTION

AND CLOAKED IN DARKNESS,

KRETSCHMER AND HIS CREW
ARE READY TO STRIKE.

[SPEAKING GERMAN]

Grove: THEY ATTACK AT NIGHT
ON THE SURFACE

WHEN THE ASDIC DOESN'T WORK,
THE SONAR DOESN'T WORK...

[EXPLOSION]

AND THEREFORE THEY CREATE CHAOS,

THEY CREATE A CERTAIN AMOUNT
OF SHOCK EFFECT,

AND LARGE NUMBERS OF SHIPS

THEN BLOW UP IN,
IN QUICK SUCCESSION.

Narrator:
ABOARD THE LEAD BRITISH ESCORT

MACINTYRE SCANS THE PERIMETER

FOR THE U‐BOAT
THAT'S RAVAGING HIS SHIPS.

Milner:
IF THE ESCORT GETS A SNIFF,

IT CAN STRIKE AGAINST THE PACK.

IT CAN PUSH IT OFF

AND MAYBE GET THROUGH THE NIGHT
WITH VERY FEW LOSSES.

Narrator: BUT AT 1 A. M.
ANOTHER SUBMARINE IS DETECTED.

MACINTYRE SPOTS SCHEPKE

Witt: IN SUCH A BATTLE SITUATION

YOU CAN'T THINK
FOR HOURS AND HOURS

OVER, OVER WHAT TO DO NEXT,

AND SO MADE THIS
SPLIT‐SECOND DECISION

TO EVADE AN ATTACK
BY THE DESTROYER BY DIVING.

Sailor:
LET'S GO, LET'S GO, LET'S GO.

Narrator:
MACINTYRE SUMMONS HMS VANOC

TO JOIN HIM
IN A DEPTH CHARGE ATTACK.

Sailor #1: COME ON, BOYS,
LET'S GO.

Sailor #2: SAILORS CLEAR!

Grove: DEPTH CHARGES
ARE VERY LARGE EXPLOSIONS.

[BOOM]

AND IF THEY OCCUR
CLOSE TO THE SUBMARINE,

THEN THEY DO A LOT OF DAMAGE.

[EXPLOSIONS]

Witt: WALLS BECOME UNTIED.

WATER LEAKS IN.

CONTROLS BURST, BULBS BURST.

ALL KINDS OF DAMAGES
ARE INFLICTED.

[SHOUTING IN GERMAN]

[EXPLOSIONS]

Narrator: THE DAMAGE
IS OVERWHELMING.

Grove: IT LEAKS SO BADLY
THAT IF IT DOESN'T COME UP,

IT'S PROBABLY GONNA SINK.

Narrator: ON MACINTYRE'S SHIP,
HMS WALKER,

THE SONAR OPERATOR STRUGGLES
TO PING U‐100

WITH THE ASDIC SYSTEM

IN AN OCEAN DISTORTED
BY EXPLOSIONS.

Grove: THE SEA IS
A VERY COMPLICATED ENVIRONMENT.

AND OF COURSE IF YOU'RE DROPPING
DEPTH CHARGES, IT'S‐‐

IT'S QUITE HARD TO ACTUALLY
SEPARATE THE DEPTH CHARGES

FROM THE SUBMARINE.

ANOTHER PROBLEM WAS
AN ASDIC FACED FORWARDS,

AND YOUR WEAPONS WERE DROPPED
OVER THE STERN,

THE REAR OF THE SHIP.

SO THIS MEANS THAT WHEN YOU'RE
ATTACKING A SUBMARINE,

THERE IS A GAP BETWEEN
YOUR LOSING CONTACT

AND THE DEPTH CHARGES
ACTUALLY BEING DROPPED,

AND THEN YOU HAVE TO
REACQUIRE THE TARGET.

Narrator: NEARBY, HMS VANOC USES
ITS FIRST‐GENERATION RADAR

TO SCAN FOR U‐100
IN CASE IT SURFACES.

THE NEW TECHNOLOGY
COULD DELIVER A TARGET,

BUT ITS APPLICATION IS LIMITED.

Milner: THE FIRST RADAR
THEY PUT IN SERVICE

IS THE TYPE 286,
WHICH IS A 1.5‐METER RADAR,

FIXED TO THE MASTHEAD.

THE ESSENTIAL PROBLEM
WITH TYPE 286 RADAR

IS THE TARGET HAD TO BE
STRAIGHT AHEAD.

YOU COULDN'T TURN THE ANTENNA,
SO YOU HAD TO POINT THE SHIP.

Narrator: JUST AFTER 3:00 A. M.,

SCHEPKE POPS UP A THOUSAND YARDS
AWAY FROM THE ESCORTS,

BETTING HE CAN REPAIR
THE FLOODING

AND LIMP AWAY TO SAFETY.

IN AN INCREDIBLE TWIST...

Controller: CONTACT DEAD AHEAD.

Narrator:
...HE LANDS DIRECTLY IN FRONT

OF THE FIRST RADAR SYSTEM,
ABLE TO DETECT HIM.

Milner: IF THEY'D BEEN
A LITTLE BIT LEFT OR RIGHT

OR SOME OTHER PLACE,

THE 286 ON THE MASTHEAD PROBABLY
WOULDN'T HAVE PICKED IT UP.

Narrator: VANOC RACES HEAD ON.

Witt: THE COMMANDER DECIDES
TO RAM THE U‐BOAT.

Narrator: HAVING PICKED UP

Narrator: ABOARD U‐99,

KRETSCHMER IS OBLIVIOUS

OUT OF TORPEDOES,

U‐99'S CREW CLEARS THE CONVOY

Grove: THIS IS A CLASSIC
KRETSCHMER ATTACK,

FIVE SHIPS SUNK,
SO HE SEEMS TO BE DOING WELL.

BUT NOW THE TRAINING
OF THE ESCORT FORCE COMES IN.

THEY CARRY OUT WHAT THEY CAN
OF A SYSTEMATIC SEARCH.

Narrator: AS U‐99 SLINKS AWAY,

KRETSCHMER'S LOOKOUT
SPOTS MACINTYRE'S DESTROYER.

[SPEAKING GERMAN]

Narrator: IN A PANIC

THE CREWMAN IS CONVINCED
THEY'VE BEEN DISCOVERED.

[SHOUTING IN GERMAN]

[BELL RINGS]

Narrator: ON THE CREWMAN'S
WARNING, THE SUBMARINE DIVES.

Witt: WHEN HE SAW THIS DESTROYER
EXTREMELY NEAR,

HE SIMPLY EXPECTED THAT THEY
WOULD HAVE BEEN DETECTED

BY THE DESTROYER,

AND SO MADE THIS
SPLIT‐SECOND DECISION

TO EVADE AN ATTACK
BY THE DESTROYER BY DIVING.

Narrator: MACINTYRE'S LOOKOUTS
WERE UNAWARE OF U‐99.

BUT AS THE SUBMARINE DESCENDS,

THE DESTROYER'S SONAR
COMES INTO PLAY.

Milner: THEY'RE LISTENING
ALL THE TIME,

AND THEY'RE PLAYING THIS KIND
OF DEADLY GAME OF CAT AND MOUSE.

THE SUB'S DOWN HERE,

AND HE'S LISTENING TO YOU
PING OFF HIM.

AND AT SOME POINT,
BECAUSE THE SONAR BEAM IS FIXED,

IT'S GONNA SWEEP OVER THE SUB.

Operator: NEW CONTACT.

RANGE, 400 YARDS.

Grove: ONCE IT CAN BE
PICKED UP ON ASDIC,

IT CAN BE ATTACKED
WITH DEPTH CHARGES.

Narrator: MACINTYRE'S CREW
LAUNCHES ITS UNDERWATER BOMBS...

Sailor: LET'S GO, LET'S GO!

Narrator: WITH CONTROLS FAILING,

THEIR EQUIPMENT AND GAUGES
SHATTERED,

KRETSCHMER AND HIS CREW
PLUNGE TOWARDS THE SEAFLOOR

IN A SEVERELY WOUNDED SUBMARINE.

Milner: THEY HAD TWO OPTIONS
AT THAT POINT.

YOU CAN BLOW BALLAST AND GET OUT
OR YOU BECOME A BOTTOM FEATURE.

Narrator: KRETSCHMER'S CREW
ATTEMPTS TO BLOW OUT WATER

TO RAISE THEIR
PLUMMETING U‐BOAT.

Witt: THE ONLY WAY OF ESCAPING
WAS RETURNING TO THE SURFACE,

SO THIS WAS THE DECISION
KRETSCHMER MADE

SIMPLY TO SAVE

Narrator:
BUT FROM THE SINKING SUBMARINE,

HITLER'S TOP U‐BOAT ACE
ORDERS A FINAL TRANSMISSION.

Witt: AFTER HIS LUCK

KRETSCHMER STILL
IS THIS PROFESSIONAL.

HE SENDS A LAST MESSAGE
TO DÖNITZ, VERY SHORT,

SIMPLY SAYS DEPTH CHARGE,
TWO DESTROYERS,

53,000 TONS, KRETSCHMER.

Milner: THAT LAST MESSAGE
HE SENDS FROM THE SUBMARINE,

I'VE SUNK A NUMBER OF SHIPS,
SOME ODD THOUSAND TONS,

LEAVING THE SUB, KRETSCHMER.

UM, THAT, THAT'S JUST
AN INDICATION

OF WHAT A COOL CUSTOMER
HE ACTUALLY WAS.

Narrator: MORE THAN FIVE HOURS
AFTER U‐99 LAUNCHED ITS ATTACK,

KRETSCHMER ORDERS
HIS CREW ON DECK

TO PREPARE FOR SURRENDER.

Grove: KRETSCHMER,
I THINK TO CALM HIS CREW,

LIGHTS A CIGAR, JUST TO SHOW
THAT HE'S STILL IN, IN CHARGE.

HE SIGNALS TO THE BRITISH
TO TAKE OFF HIS CREW.

AND THE BRITISH WILL DO THAT

BECAUSE THERE ISN'T
MUCH HATRED MAN, MAN TO MAN.

ONCE THE SUBMARINE'S SUNK,
THAT'S THE JOB DONE.

Narrator:
KRETSCHMER IS THE LAST ONE

PULLED ABOARD
THE BRITISH DESTROYER.

MACINTYRE CLAIMS THE ACE'S
BINOCULARS AS HIS PRIZE.

Grove: KRETSCHMER IS TREATED
VERY WELL ON BOARD HMS WALKER.

HE PLAYS BRIDGE,
HE'S PLIED WITH WHISKEY.

THEY'RE VERY, UH, UH, PLEASED

THAT THEY'VE CAPTURED SOMEBODY
SO DISTINGUISHED.

Narrator: KRETSCHMER SPENDS
THE REST OF THE WAR

AS AN ALLIED PRISONER.

THE BATTLE AGAINST CONVOY HX 112

COST DÖNITZ TWO
OF HIS TOP SUBMARINES.

Milner: WHEN KRETSCHMER AND
SCHEPKE GO DOWN IN MARCH OF '41,

THAT'S A CATASTROPHIC
DEVELOPMENT

FOR GERMAN PUBLIC RELATIONS.

YOU'VE TRUMPETED THE SUCCESS
OF THESE HEROES,

AND NOW ALL OF A SUDDEN
THEY'RE GONE.

AND THE FLIPSIDE OF THAT

IS THAT THE BRITS ACTUALLY
APPEAR TO BE GIANT KILLERS

'CAUSE THEY'VE TAKEN THEM OUT.

IT'S TRAGIC THAT THEY LOSE THEM
ALL IN A VERY SHORT PERIOD.

BUT YOU'VE STILL GOT
LOTS OF YOUNG,

VERY CAPABLE SUBMARINERS
COMING ALONG.

THE GERMAN SUBMARINE FLEET
IS BY NO MEANS DONE.

IT'S REALLY
JUST GETTING STARTED.
