It was made up entirely of older reserve regiments which was armed with antiquated weapons of world war one vintage.

First, it was to prepare the north of Zeeuws Vlaanderen from a possible German attack across the Scheldt while the remaining troops of the French 7th Army withdrew from the region.

As the Lys Battle unfolded and the Germans decisively punctured the Belgian defences at the river, the units of the 15th Division were called in to serious action for the first time.

After several preliminary bombardments, the Germans succeeded in destroying several companies at the first attack, successfully enveloping the remainder of two of its battalions.

As the situation at the Lys became desperate, Army Command was throwing the last remaining reserves into the fray.

During the night of the 26th, it was gradually reinforced by cyclists, machine and AA gun companies from different units.
