Mission Boston was a parachute combat assault at night by Major General Matthew Ridgway's U.S. 82nd Airborne Division on June 6, 1944, part of the American airborne landings in Normandy during World War II. Boston was a component element of Operation Neptune, the assault portion of the Allied invasion of Normandy, codenamed Operation Overlord. 6,420 paratroopers jumped from nearly 370 Douglas C-47 Skytrain troop carrier aircraft into an intended objective area of roughly 10 square miles (26 km2) located on either side of the Merderet river on the Cotentin Peninsula of France, five hours ahead of the beach landings.
The drops were scattered by bad weather and German anti-aircraft fire over an area three to four times as large as that planned. Two inexperienced units of the 82nd, the 507th and 508th Parachute Infantry Regiments (PIR), were given the mission of blocking approaches west of the Merderet River, but most of their paratroops missed their drop zones entirely. The veteran 505th PIR jumped accurately and captured its objective, the town of Sainte-Mère-Église, which proved essential to the success of the division.
