HMS Oswald (Lt.Cdr. David Alexander Fraser, RN) was rammed and sunk about 15 nautical miles south-east of Cap Spartivento, Italy in position 37º46'N, 16º16'E by the Italian destroyer Vivaldi on 1 August 1940. 3 dead, 52 survivors.

On 30 July 1940 Oswald had attacked an Italian convoy, missing, then sent a contact report about Italian naval units transiting the Straits of Messina and moved to the Ionian Sea. By now, all Italian ASW forces in the area were aklerted to her presence and were on the lookout.

On 1 August she was spotted while running surfaced, 12 nm south of Capo Spartivento Calabro, a scant 2500 m away by an Italian Destroyer Division consisting of Ugolino Vivaldi, Nicoloso da Recco, Antonio da Noli and Antoniotto Usodimare: Vivaldi was closest and came about immediately, impacting the boat at 2305 hrs and sinking her. There were 3 dead and 52 survivors rescued by the destroyers.
