The Action of 1 November 1944 also known as the Ambush off Pag Island was a naval engagement in the Kvarner Gulf of the Adriatic Sea, between islands of Pag and Lussino (present-day Lošinj) on 1 November 1944. It was fought between a British Royal Navy destroyer flotilla and a Kriegsmarine force of two corvettes and a destroyer. The German flotilla was deployed to escort a convoy retreating from Šibenik to Fiume (present-day Rijeka). The British managed to destroy all three German ships in return for no loss.
