SS Somersby was a British cargo steamship that was built in 1930, sailed in a number of convoys in the Second World War and was sunk by a U-boat in 1941.

[14] She returned in October with a cargo of flour, sailing via Sydney, Nova Scotia, where she joined Convoy SC 7 bound for the UK.

A wolf pack of U-boats found the convoy on 16 October and quickly overwhelmed it, sinking many ships over the next few days, but Somersby was one of the few that survived.

Somersby left Halifax with SC 30 on 29 April[22] but orders were given to scatter the convoy, due to the presence of German U boats in the area.

[4] On the morning of 13 May she was southwest of Reykjavík when the German submarine U-111, commanded by Kapitänleutnant Wilhelm Kleinschmidt, sighted her at 1141 hrs and fired two torpedoes.

[4] At 1246 hrs the U-boat fired a coup de grâce that hit Somersby's bow, causing her to sink nose first and her rudder was out of the water.
