I am not a Doubting Thomas, but there is something wrong with this picture.
11th A/B Division served in the Pacific, and was credited with the New Guinea, Leyte and Luzon campaigns. It was never in ETO.
True, the 188th GIR was in the 11th A/B as late as 1944, then was redesignated 188th Parachute Infantry Regiment during a re-organization in 1945, but like I stated, it remained in the Pacific.
The only "jumpers" I can identify who parachuted onto both Italian and French soil was the 82nd A/B Division. It air assaulted Sicily, 9 July 1943, and Normandy on D-Day, 6 June 1944.
*The 82nd landed in North Africa on 10 May 1943, and due to its long combat history, would have needed replacements along the way. He may have been a replacement there, or later.*
The 11th A/B Division arrived in the Paific 25 May 1944. The 101st A/B Division also air assaulted Normandy, 6 June 1944, but did not see action in Italy.
The only remaining A/B unit, 13th A/B Division did get overseas, arriving ETO 6 Feb 1945. It never entered combat, but was credited with the Central Europe campaign for havng been in the combat zone at the time.
I suspect that somewhere along the way there was a change in assignments for your dad, and that his combat tour was with 82nd A/B Division.(My * above should be read here)
From a personal viewpoint, I feel that his service in glider action was among the most daring during WW II, right up there with tank duty and submarine duty.
In the end, he may have had a short-term assignment with still another unit, which often involved a transportation necessity.
Please feel free to get back to me if needed.
If you can scan and forward his separation papers it mighthelp our cause. OK?
