D-Day

D-Day, 6 June 1944, and the following days, were decisive in the war on Germany. British and American troops, in roughly equal numbers, including Canadians in the British total, established themselves on the Normandy coast; Rommel, commanding the German side, could not concentrate sufficiently powerful forces to dislodge them. D-Day, though cloudy and windy, justified Eisenhower's decision, as supreme commander, to accept, at the last minute, a comparatively hopeful weather forecast. Montgomery, in command of ground forces, dispatched five infantry divisions, to five separate beaches, plus three airborne divisions, landing over 150,000 men on the first day. The landings were supported by more than 100 warships, with 4-inch or larger guns, bombarding coastal defences. On one American beach, Omaha, against a good-quality German division and well-prepared German defensive works, casualties were high. The British and American air forces virtually stopped German movement of troops or supplies by day and made impossible a co-ordinated German counter-attack. Allied air forces contributed decisively to the 1st US Army break-out which led to the liberation of France and Belgium in August and September 1944.
