This counter-offensive, known as the Von Rundstedt Offensive, began on 16 December 1944. The 6th SS Panzer Division, Hasso von Manteuffel's 5th Panzer Army and the 7th Army, led by Erich Brandenberger, landed in the Ardennes on 25 December.

The battle was not as successful as the offensive of May 1940. Even though the German soldiers managed to surprise the enemy, they were soon faced with manpower and fuel shortages. These shortages put a sudden brake on the offensive and Adolf Hitler's plans, and on 25 January 1945, the Allies succeeded in pushing the German troops back beyond their starting line.

The town of Saint-Hubert was liberated on 11 January 1945 by French paratroopers from the 4th Special Air Service, shortly followed by American soldiers from the 87th Infantry Division.

The milestone marks the end of this last attempt. The monolith comes from Libramont and the engraving was done by Honoré Hanot.
