 Prior to the Battle of Normandy, the Allied command feared that the losses suffered by glider groups would be as high as 50-70% before even encountering the enemy.This fear was based on expectations for high numbers of crash landings and encounters with anti-aircraft defences.The actual losses were less than the estimates and were comparable to the losses of associated parachute units; the losses suffered by certain Glider Artillery battalions (e.g., the 319th and 320th of the 82nd Airborne Division) were higher than the losses of the associated Glider infantry (i.e., the 325th) primarily because the two artillery battalions landed in the evening hours of D-Day and the landing zone (LZ-W) near St.
