When mobilization was announced, the 10th Infantry Division, was part of the First Reserve with some of its regiments already active in the army.

At the start of the German invasion, the 10th Infantry Division began fully operating in its sector.

Disagreement was brewing among the Allied command as the K-W line was manned by both the Belgians, the French, and British forces.

After the abandonment of the K-W line by the Allies, the 10th Infantry Division was on to a slow retreat as the lack of vehicles meant delays.

The 10th Infantry Division now had to defend a sector 11 km wide stretching from Ledegem, to Izegem.
