The battalion took part in operations in Tunisia in late 1942 to May 1943, suffering heavy casualties. The battalion and the brigade took part in Operation Fustian, when the Allies invaded Sicily and, again, suffered heavy casualties and was withdrawn to England in late 1943 to train and prepare for the Allied invasion of France. The battalion wasn't used in the initial invasion on 6 June 1944, D-Day, but was held back in the UK in reserve in case any of the five invasion beaches encountered serious difficulties and needed support. The plan turned out not to be required. During the fighting in Normandy numerous plans to drop the 1st Airborne were formed, none of which came to fruition. Finally, in September 1944, the battalion dropped into Arnhem the Netherlands with the rest of the 1st Airborne Division, as part of Operation Market Garden, where they suffered extremely heavy casualties and never saw combat again for the rest of the war.
