[7] On 6 March 1943 Clan Alpine left Liverpool bound for Walvis Bay, Durban, Aden and Port Sudan carrying 11,317 tons of general cargo, including army and naval stores.

[3] Early on 13 March the German submarine U-107 sighted OS 44 in the North Atlantic west of Cape Finisterre.

At 0530 hours U-107 fired several torpedoes at the convoy and hit four ships: Clan Alpine, Marcella, Oporto, Sembilangan.

[9] She did not sink, but it was not practical to repair her or tow her to safety so her surviving crew abandoned her.

The escorting sloop HMS Scarborough rescued the survivors and scuttled Clan Alpine with depth charges.
