The group flew paratroopers on airborne assaults on Normandy (Operation Overlord); Southern France (Operation Dragoon); the Netherlands (Operation Market Garden), and Germany (Operation Varsity). It also flew combat resupply missions in the relief of Bastogne in 1945. The 435th was awarded a Distinguished Unit Citation for its actions during the Normandy invasion.
