The Brigade Piron was deployed to France in August 1944 following the Normandy Landings. Although it was kept in reserve for most of the campaign, the unit was deployed in combat in Normandy alongside the British 6th Airborne Division and, later, the Guards Armoured Division. Among other operations, the unit liberated the French town of Honfleur on 25 August. It was also involved in the Liberation of Belgium in September 1944 and entered Brussels on 4September, the day after the arrival of the first British troops. The brigade was then moved to Dutch Limburg, where it participated in heavy fighting until November.
