Day 261 May 18, 1940

Despite the stop order imposed on the German tanks, Rommel pushes 7th Panzer Division on to Cambrai and then halts to consolidate his supply lines and protect his flanks. He has advanced 85 miles due West (more than half way to the English Channel) in 5 days, capturing over 10,000 French prisoners & 100 tanks. His losses are about 50 dead and 100 wounded. The rapid pace constantly wrecks Allied counterattack plans; French formations are overrun while they prepare to attack. 7th Panzer becomes known as the “Ghost Division” for its ability to appear unexpectedly. Over 6 million French refugees take to the roads, convinced they will be occupied any minute. Populations of cities in Northern France drop by 90%.

German U-boats resume harassing Allied shipping in North Atlantic and around Britain, after several weeks patrolling the Dutch, Danish and Norwegian coasts in support of the invasions. U-60 & U-62 sail from Kiel, joining U-37 & U-43 at sea.
