The Italian blockade breaker Cortellazzo had departed Bordeaux bound for Japan on 29 November 1942. The next day the ship was spotted by a Sunderland flying boat. The British destroyer HMS Redoubt (Lt.Cdr. N.E.G. Ropner, DSO, RN) and the Australian destroyer HMAS Quickmatch (Lt.Cdr. R. Rhoades, DSC, RAN) were detached from convoy KMF-4 to intercept the Italian ship. They did so on 1 December and after the Italians had abandoned ship she was sunk by torpedo by HMS Redoubt about 470 nautical miles west of Cape Finisterre, Spain in position 44º00'N, 20º00'W.

At 0500 on 25 December 1944, HMAS Quickmatch (Lt.Cdr. O.H. Becher, DSC, RAN) was ordered from port during what became known as the "Christmas Scare" off Sydney, Australia.

It lost radar contact with merchant ship at 0300 on the 26th and assumed it sank.
