Service history

U-110 made three wartime patrols, and sank 10 ships, totalling 26,963 gross register tons (GRT). Her first success was the British Q ship Penshurst, with which she fought an engagement on 24 December 1917. Penshurst sank shortly after.

Fate

U 110 was sunk on 15 March 1918 north-west of Malin Head at 55°4′N 8°6′W.^{[citation needed]} She was found and depth-charged by British destroyers Michael and Moresby. 39 men were lost.^[5]
