The German assault on Gembloux itself had gotten nowhere. Rebuffed by rock-solid Moroccan infantry backed by extremely accurate French artillery, the German infantry paid a heavy price. The one bright spot for them was a point between Ernage and Gembloux where they had been able to punch a hole through the railway line and overrun the hidden antitank guns there. Then word came around midday that 3rd Panzer Division had pierced the line at Perbais and Ernage, and that brought on a new German attack with air support. The French began to give way around the Lagasse farm just north of Gembloux, but then the armored counterattack that had been ordered at 11:30 finally began.

The Germans poured heavy fire into the French whose infantry became separated from their tanks. Some of the latter were disabled by German AT fire or pinned down by German tanks arriving from Ernage to the north. By 1830 the counterattack had ground to a halt, but the Germans had been stopped and ended up withdrawing behind the railway. Unfortunately, as darkness fell on the battlefield the French success at Gembloux was voided by German victory farther south.

Swallows of Death may be played with the 1st edition pieces and maps from 1940: Fall of France.

When a French piece in the order of battle was apparently Moroccan and was in the Division Marocaine set, that piece was used in the order of battle list. Substitute equivalent French Army pieces Moroccan pieces when the Moroccan piece is unavailable.

(Special note: Marocain HMG units have a Movement factor of 2.)
