 This class of U-boat did not carry a deck gun.Leaving Horten Naval Base in Norway on the 6 February, "U-2322" proceeded to the East coast of Scotland, particularly in the area of St Abb's Head, where lone coastal shipping sometimes passed, believing that German U-boats would not bother waiting in such a dangerous spot for such insignificant prey.This plan finally worked on the 25 February, when the 1,300 ton coastal cruiser SS "Egholm" was sunk by a torpedo.
