Luxembourg's military involvement could play only a "symbolic role" for the allied cause, and numerous Luxembourgers fought in allied armies. From March 1944, Luxembourg soldiers operated four 25 pounder guns, christened Elisabeth, Marie Adelaide, Marie Gabriele and Alix after the Grand duchess' daughters, as part of C Troop, 1st Belgian Field Artillery Battery of the 1st Belgian Infantry Brigade, commonly known as the "Brigade Piron" after its commander Jean-Baptiste Piron. The Troop numbered some 80 men. The battery landed in Normandy with the Brigade Piron on 6 August 1944 and served in the Battle of Normandy and was involved in the Liberation of Brussels in September 1944.
