72 years ago this weekend, thousands of planes and ships filled the air and sea at the shores of Normandy, France, in the Normandy Invasion, or Operation Overlord. This was a historic Allied juggernaut into western Europe. It was launched on June 6, 1944, in what is considered the most celebrated Declaration-Day of the war, with the simultaneous landing of U.S., British, and Canadian forces on five separate beachheads spearheading into Normandy, France.
Within 2 months, all of northern France was liberated, and the invading forces reorganized for the drive into Germany, where they would eventually meet with Soviet forces advancing from the east to bring an end to the Nazi Reich.
