Answer:
The Normandy landings, more commonly known as D-Day, were especially tragic. On June 6th, 1944, during WWII, Allied forces launched a combined naval, air and land assault on Nazi-occupied France. The Allies landed more than two million men in northern France and suffered more than 226,386 casualties: 72,911 killed/missing and 153,475 wounded. German losses included over 240,000 casualties and 200,000 captured.
The cost of the Normandy campaign was high on both sides. Although there were many casualties, D-Day marked the beginning of the liberation of German-occupied Western Europe from Nazi control.
