The 1st Battalion spent the whole war as part of the 29th Independent Infantry Brigade Group. The battalion participated in the Battle of Madagascar in 1942 as did the 2nd Battalion, a unique achievement for the regiment to have both its regular battalions involved in the same action. They were then transferred to India to fight in the South-East Asian Theatre. In 1944 the 29th Brigade became part of the 36th Infantry Division, previously a British Indian Army formation and one of two British divisions fighting the Japanese. The 36th Division spent the rest of the war under command of the British Fourteenth Army.
