After moving to France in September, the group dropped paratroops of the 82nd Airborne Division near Nijmegen and towed gliders carrying reinforcements during the airborne attack on the Netherlands. In December, it participated in the Battle of the Bulge by releasing gliders with supplies for the 101st Airborne Division near Bastogne. When the Allies made the air assault across the Rhine River in March 1945, each aircraft of the 439th towed two gliders with troops of the 17th Airborne Division and released them near Wesel. The group also hauled food, clothing, medicine, gasoline, ordnance equipment, and other supplies to the front lines and evacuated patients to rear zone hospitals. It converted from C-47s to C-46s and the 439th used the new aircraft to transport displaced persons from Germany to France and Belgium after V-E Day.
