The Battle of The Atlantic

Marking the 60th anniversary of the Battle of the Atlantic this series vividly recounts the tale of the longest, most bitterly fought campaign of World War II.
From 1939 until 1942, Hitler's U-Boats - his 'grey wolves' - threatened to do what his air force couldn't and starve Britain into submission. The result was arguably the most complex naval battle in history. Battles might be won or lost, Winston Churchill wrote, but Britain's power to fight on - to keep itself alive - depended above all, on the outcome of the war fought in the waters of the North Atlantic.
