The most unsettling thing for Manstein was that the French Army fought with great discipline.
When the tanks weren't under enemy fire, the French infantry would always enter the houses on both sides ahead of the tanks to conduct search and combat.
They would throw two grenades through the doors or windows, and after the explosion, they would rush into the buildings with submachine guns and shotguns to clear them.
Under this assault of submachine guns and grenades from the French Army, the German Army soldiers lurking inside the buildings couldn't be said to be easy targets, but often only a few gunshots or explosions were heard before the fight was over.
The tanks continued to carefully advance, sometimes stopping to adjust the tank cannon to fire at a window, causing the German Army soldiers hiding there to cry out in despair.
Perfect infantry-tank coordination, Manstein marveled, the infantry covering the tanks, and tanks covering the infantry.
