The 4th Battalion was in Northern Ireland in the 160th Infantry Brigade attached to the 53rd (Welsh) Infantry Division. In June 1944 the battalion, under Lieutenant Colonel Charles Coleman, was, after many years of training, ordered to France to join the British Second Army in the Normandy Campaign. From the start of the campaign the 4th Battalion was involved in fierce fighting during the Battle for Caen, and around the Falaise Pocket, the Battle of the Bulge and the Battle of the Reichwald where it sustained very heavy casualties and involved some of the fiercest fighting in the North West Europe Campaign for British soldiers as they were up against determined German paratroopers.
