At 12.51 hours on 5 July 1940 the Magog (Master T. Swales Doughty), a straggler from convoy HX-52, was damaged by a stern torpedo from U-99 that exploded prematurely. The U-boat surfaced after 20 minutes and began to shell her until the master and 22 crew members abandoned ship in a lifeboat about 58 miles west-southwest of Fastnet. At 13.52 hours, a G7e torpedo was fired that hit aft of amidships and broke the ship in two. The stern sank, but the foreship remained afloat on the cargo of timber even after the U-boat fired three rounds from the deck gun into it at 15.05 hours. On 8 July, the wreck foundered in 50°32N/11°20W. The survivors had been questioned by the Germans and were later picked up by the Swedish merchant Fidra and landed at Queenstown, Cork.
