Their D-Day objective during Mission Boston, part of the American airborne landings in Normandy, was to help secure the Merderet River crossings.

Although their target was supposed to be in Drop Zone T, north of Amfreville, the confusion caused by clouds and flak resulted in a wide scattering of the unit.

The 507th continued to fight in the Battle of Normandy, sustaining heavy casualties (losing almost 200 men in two days shortly before being withdrawn), before returning to England in July.

As part of the 17th Airborne, the 507th was not utilized in Operation Market Garden in September 1944 and was still in England training with the new division when the Battle of the Bulge began in December 1944.

Finally, the 507th Parachute Infantry dropped near Wesel, Germany on 24 March to spearhead the division's assault during Operation Varsity, the airborne crossing of the Rhine.

The story focuses on the German massacre of French civilians, and wounded paratroopers of the 507th that were taken prisoners, in retaliation for battle at the village of Graignes.
