German submarine U-757 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. Launched from Werk 140 at the Kriegsmarinewerft (KMW) in Wilhelmshaven Lower Saxony (Then, the Free State of Oldenburg), U-757 served with 6th U-boat Flotilla from February 28, 1942 to January 8, 1944 under the command of Korvettenkapitän Friedrich Deetz.[1]

Record[edit]

U-757's first victims were the British transport vessel HMS LCT-2398 - destroying 291 tons of shipping - in the convoy HX 228, and the American merchant vessel William C. Gorgas- destroying a further 7,197 tons of shipping. Both incidents occurred on 11 March 1943, fourteen days into her twenty-five day long third patrol. Of the seventy-three crewmen on board the Gorgas, twenty-two perished.

On her fourth patrol, U-757 sank the Norwegian Fernhill on 7 August 1943, thirty-one days into her sixty day patrol, 4,116 tons of shipping lost in the sea. Of the ship's forty-four crewmen, forty survived the attack, being rescued by the American tanker Idaho two days later.

Fate[edit]

On 8 January 1944 in the North Atlantic, south-west of Iceland, U-757 was hit by depth charges from the British frigate HMS Bayntun and the Canadian corvette HMCS Camrose. U-757 went down with all 49 seamen, at position 50°33′N 18°03′W / 50.550°N 18.050°W / 50.550; -18.050.
