At 01.03 hours on 13 Nov 1943 the unescorted Pompoon (Master Edward Condell) was hit by one torpedo from U-516 about 75 miles north of Cartegnea, Colombia. The torpedo struck amidships on the port side and broke the ship in two. Both ends sank with the midship part sinking first on both ends. The 23 crew members and four armed guards on board had no time to launch a lifeboat. Five survivors managed to rescue themselves on a raft that had floated free, but one of them died the next day and was buried at sea. In the afternoon of 3 December, the four survivors (a messman and three armed guards) were picked up by a Panamanian ship in 09°45/76°45W and were taken to Cristobal where they were hospitalized in serious condition.
