Today is the 70th Anniversary of D-Day. The D-Day anniversary marks memory of the date, June 6, 1944, when Allied forced stormed the beaches of Normandy during World War II. It is known as the largest seaborne invasion in history. The operation, part of a larger invasion operation named Operation Overlord, involved a complex combination of sea invasion combined with aerial bombardment, naval bombardment, and paratrooper insertion behind enemy lines. Securing the beachhead was the first step of many in the eventual push to Germany and the eventual end of WWII.
