Service history

U-131 sailed from Kiel on her first and only patrol on 27 November 1941.
On 6 December she torpedoed and sank the 4,016 ton British cargo ship Scottish Trader, a straggler from convoy SC 56, en route from Philadelphia to Liverpool, south of Iceland. All 43 of the crew perished.
On 17 December U-131 was spotted by a Grumman Martlet aircraft from the escort carrier while shadowing Convoy HG 76 as part of the Seeräuber wolfpack.
U-131 was forced to dive, while ships of the 36th Escort Group, commanded by Frederic John Walker in, with four other escorts, including the destroyers, and and the corvette, approached to continue the attack. Detected by Stanleys ASDIC, she was depth charged by Pentstemon, and forced to surface, due to chlorine gas coming from the batteries. Unable to dive, she attempted to escape by running at full speed on the surface. While under pursuit U-131 shot down an attacking Martlet aircraft, killing the pilot, but was then shelled by the escort group, which scored several hits. Realizing that the situation was hopeless, the crew abandoned the U-boat and scuttled her. All 47 of the crew survived and were taken prisoner.
