In April 1943 the unit was moved to North Africa, landing at Algiers before later moving to the Suez where they began preparing for operations as part of Operation Husky, the Allied invasion of Sicily. On 10 July 1943, landing ahead of the main force near Cassible, a few miles south of Syracuse on the Sicilian coast, half of No. 3 Commando—Nos. 4, 5 and 6 Troops—under the command of Durnford-Slater, carried out a night time attack on an Italian artillery battery without suffering a single casualty. Meanwhile, Nos. 1, 2 and 3 Troops under the command of Peter Young, carried out a landing at Scoglio Imbiancato unopposed after a series of navigational delays meant that they landed later than planned. Nevertheless, the two forces managed to link up before capturing the town of Cassible later that night.
