Historical
Despite the stop order imposed on the German tanks, Rommel pushed 7th Panzer Division on to Cambrai (better known for the British tank action there in 1917) and then halted to consolidate his supply lines and protect his flanks. Rommel ordered his tanks and self-propelled guns to drive across the open fields and create as much dust as possible, creating the illusion that the advancing force was much larger than it actually was. The defenders abandoned the town without firing a shot. He had advanced 85 miles in 5 days, capturing over 10,000 French prisoners and 100 tanks. His own losses were about 50 dead and 100 wounded. 7th Panzer Division earned the nickname of the “Ghost Division” for its ability to appear unexpectedly.
Guderian’s 2nd Panzer Division captured Saint-Quentin.
Over six million French refugees took to the roads. French Prime Minister Paul Reynaud announced he was recalling the ambassador to Spain Philippe Pétain to make him Vice Prime Minister.
