This was the German evacuation of naval forces from Sibenik to Fiume (Rijeka) on the Dalmatian coast of German-occupied Yugoslavia (2 November 1944).

In the course of this undertaking, the torpedo boats TA 20 and TA 21, corvettes UJ 202 and UJ 208, and minesweeper R 187 were intercepted by British warships in 'Exterminate', losing TA 20 and the two corvettes.
