June 6, 1944. The day that Operation Overlord began. It started with landings on the beaches of Normandy as hellfire rained down on them from the cliff tops.

It continued with paratroopers jumping out of planes into a countryside that could be housing German soldiers behind every rock wall, house, shed, or tree.

The Allied effort included 12,000 airplanes, two-thirds of which were British. 1,213 ships sailed for Normandy. 892 were British, 200 were American.

But on that day, at that hour. Every soldier, every officer, every General had one purpose and one thought in mind. Stopping Hitler in his tracks.
