The 1st Battalion was serving in the Middle Eastern theatre and fought in the North African Campaign and the Western Desert Campaign on the outbreak of war, and was assigned to many different brigades and divisions until late June 1942 when, fighting in Tobruk, the battalion was captured. The few survivors of the battalion returned to the United Kingdom. In Battalion was reformed, by the redesignation of the 16th Battalion, a hostilities-only battalion. In August 1944 the new 1st Battalion was transferred to the 183rd Infantry Brigade, part of the 61st Infantry Division and in June 1945 it transferred to the 184th Infantry Brigade, again part of 61st Infantry Division.
