Men lost from the boat
16 Feb, 1942
U-156 began to shell the oil refinery at Aruba in the Caribbean, but the gun crew forgot to remove the water plug from the barrel, causing an explosion that killed one man [Matrosengefreiter Heinrich Büssinger]. The gunnery officer [II WO Leutnant zur See Dietrich von dem Borne, see right] lost his right leg in this incident, and so had to be put ashore into captivity at Martinique on 21 February. The commander decided to saw off the ruined portion of the gun barrel, and using this shorter barrel, on 27 February U-156 sank a 2,498-ton British steamer.
