"How many Allied and German casualties were there on D-Day, and in the Battle of Normandy?"
"The Allied casualties figures for D-Day have generally been estimated at 10,000, including 2500 dead....Over 425,000 Allied and German troops were killed, wounded or went missing during the Battle of Normandy. This figure includes over 209,000 Allied casualties, with nearly 37,000 dead amongst the ground forces and a further 16,714 deaths amongst the Allied air forces. Of the Allied casualties, 83,045 were from 21st Army Group (British, Canadian and Polish ground forces), 125,847 from the US ground forces. The losses of the German forces during the Battle of Normandy can only be estimated. Roughly 200,000 German troops were killed or wounded. The Allies also captured 200,000 prisoners of war (not included in the 425,000 total, above). During the fighting around the Falaise Pocket (August 1944) alone, the Germans suffered losses of around 90,000, including prisoners.
Today, twenty-seven war cemeteries hold the remains of over 110,000 dead from both sides: 77,866 German, 9386 American, 17,769 British, 5002 Canadian and 650 Poles.
Between 15,000 and 20,000 French civilians were killed, mainly as a result of Allied bombing. Thousands more fled their homes to escape the fighting."
