each of which fought only the listed campaigns, and each listed a Military Platoon as an element of their respective units, and each rotated in and out of the Fourth Corps in that time frame.
The 85th shipped over to North Africa for training for the Italian mission. It was not in combat in North Africa.
It was returned intact to the states by way of Hampton Roads, VA P/E, 25 Aug 45.
I assume that this division was returned to stateside for R&R, then was to be trained for the anticipated invasion of Japan, which was scheduled for October-45.
The 88th stayed in Italy thru 1946, and disbanded there, I think.
The 91st rotated back to the states by way of Hampton Roads, 10 Sep 45, thence to Camp Rucker, AL, 14 Sep 45, where it was deactivated.
There were at least three other infantry divisions involved in Italy:
34th ID, fought in North Africa campaign, plus Naples-Foggia, and Anzio, before going the rest of the way up the boot of Italy;
On second thought, this could have been the unit you are after, for it too was credited with the three campaigns you list(plus Tunesia, Naples-Fogia and Anzio) . It was attached to IV Corps from 26 Jun 44 / 24 Jul 44. It would depend on when he joined the division.
36th ID, entered combat for the Naples-Foggia campaign, Anzio, Rome-Naples, thence to Southern France;
45th ID, fought Sicily, Naples-Foggia, Anzio and Rome-Arno campaigns, thence to SouthernFrance.
From his discharge, you may be able to identify his unit, using the bits of information I have listed.
