On the freezing nights of the North Atlantic, German U-boats didn't hunt alone: ​​they hunted in packs. This is the story of "Rudeltaktik," the wolfpack tactic devised by Admiral Karl Dönitz, which brought Great Britain to the brink of starvation and which Winston Churchill acknowledged as the only danger that truly terrified him during the war.

In this documentary from The World at War, we explore the Battle of the Atlantic, the longest campaign of the entire Second World War (1939-1945):

🐺 How a wolfpack operated: locating the convoy, assembling the U-boats, and attacking at night on the surface.

⚓ Karl Dönitz and submarine warfare against Allied convoys.

🔥 "The happy times": when U-boats sank ships with almost no resistance.

📡 The Allied counterattack: sonar (ASDIC), radar, HuffDuff radio direction finding, escorts, long-range aircraft, and the breaking of Enigma.

💀 The "Black May" of 1943 and the final price: of some 40,000 German submariners, nearly 30,000 never returned.

A story of hunters who became the hunted.
