was Mission Chicago. Mission Chicago was the 27th Serial of 52 C-47 Skytrain aircraft of the 434th Troop Carrier
Squadron. These 52 C-47s towed and equal number of CG-4A Gliders. These gliders carried 155 Soldiers, 1 Clark CA-1
Bulldozer, 16 57mm anti-tank guns and 25 vehicles. Mission Chicago was primarily an artillery reinforcement mission, with
Battery A and B of the 81st Airborne Antiaircraft Battalion aboard 44 gliders and small elements of the 326th Airborne
Engineer Battalion, 101st Signal Company, a surgical team from the 326th Airborne Medical Company and an anti-tank
platoon of the 327th Glider Infantry Regiment on the remaining 8 gliders.
The designated Landing Zone was LZ-E, a mile wide area along the road connecting les Forges and Sainte-Marie-du-Mont.
At 0354 on D-Day, 49 of the 52 gliders released over the LZ. Only 6 landed correctly on the LZ, with another 15 landing in
fields within a half mile. The remaining gliders were scattered over 2 miles from the correct LZ.
Total casualties were 5 dead, 17 injured and 7 missing, to include Brigadier General Don F. Pratt, assistant division
commander. General Pratt was killed along with the co-pilot flying his glider. This incident was fictionalized in the movie
"Saving Private Ryan".
