The brigade first went into action on 5 June 1944 during Operation Tonga, part of the Normandy landings. The objective was to destroy the Merville Gun Battery and the bridges over the River Dives. The brigade achieved all its objectives, and remained defending the left flank of the invasion zone until mid August. They then crossed the River Dives and advanced as far as the River Seine before they were withdrawn. While recovering in England, the brigade was moved to Belgium in December 1944, to counter the German attack in the Ardennes. The brigade remained on the border between Belgium and the Netherlands carrying out patrols until March 1945. Their next airborne mission was Operation Varsity, the assault crossing of the River Rhine in Germany. After this, the brigade advanced towards the Baltic Sea, arriving just ahead of the Red Army.
