The Salerno Mutiny was a mutiny by about 600 men of the British X Corps, who on September 16, 1943 refused assignment to new units as replacements during the Allied invasion of Italy. It was, specifically, men from the British 51st Highland Division and the 50th Northumbrian Division, including some veterans of the war in North Africa. About 1500 of them had sailed from Tripoli, on the understanding that they were to join the rest of their units, based in Sicily. Instead, once aboard ship, they were told that they were being taken to Salerno, to join the 46th Division, fighting as part of Lieut.-General Mark Clark's U.S. Fifth Army. Many of the soldiers felt they had been deliberately misled.
