In Enemy Hands

25.000

:00:24

At the outbreak of World War II

:00:27

Germany increased its U-boat
production by 1000%.

:00:31

Mass producing 17 new U-boats a month.

:00:35

Hitler knew the key to winning
the war in Europe...

:00:38

was to control the Atlantic.

:00:43

And control it, they would.

:00:54

By the end of 1942,
German U-boats working in groups...

:00:58

known as "wolfpacks",
sunk over 1,000 allied ships.

:01:08

This success gave Germany
a decisive advantage.

:01:16

They were winning the war,
and if this trend continued...

:01:19

all of Europe would fall.

:01:21

IN ENEMY HANDS

:01:24

In January 1943, President Roosevelt,
and Prime Minister Churchill...

:01:30

declared that stopping the U-boats
would be their top priority.

:01:36

With the US fully committed to the war,
and new advances in technology...

:01:40

the allies strike back.

:01:44

After losing an average
of only five U-Boats a month...

:01:47

Germany suffers its greatest losses
in what would be known as Black May.

:01:55

That month, allies sink
and destroy 41 U-Boats.
