On June 6, 1944, over 160,000 Allied troops stormed five beaches along the coast of Normandy, France, known as D-Day, launching the largest seaborne invasion in history. The objective was to secure the coastline and mobilize troops to liberate France from German control. Despite heavy casualties especially at Omaha Beach, the Allies were able to establish a foothold in Normandy by day's end. While the cost was high with over 9,000 troops killed or wounded, over 100,000 soldiers began advancing across Europe to defeat Nazi Germany. D-Day marked a major turning point in World War 2 towards Allied victory.
