German submarine U-757 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. Laid down as yard number 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.
