The supply services strain to the utmost to supply the Allied advance. Equipment was offloaded at the "Mulberry" harbor as well as at Cherbourg. Black troops are featured as drivers for the "Red Ball Highways," which brought supplies to the Allied front. These lines ran 700 miles. The British take the port of Antwerp largely intact on September 4th. The Germans still held the approaches to Antwerp, and the British and Canadians fight to clear the mouth of the Scheldt River so the port can be used. By the end of November, 1944, Antwerp received supply ships. Antwerp is hit with V-1 and V-2 rockets.
