It is correct, the 133rd. Infantry Regiment was one of three regiments of the 34th. Infantry Division.
However, I don't believe the division was even close to Bologna, Italy, Oct. 29, 1944.
It was probably at or perhaps approaching the Gothic Line above Florence in that time frame.
This line passed through the Apuan Mountains which make up a part of the North Apennines Mountain Range, I believe.
The offensive against Bologna started 15 Apr 45, with the 133rd. IR actually capturing it on 21 Apr 45.
I was a Chief-of-Section, 985th FA BN, II Corps, Fifth Army, at that time, and my unit frequently had fire missions in support of the British Eighth Army on the drive on Bologna, which was a primary target for both the 133rd IR and the BR VIIIth Army.
I hope that you locate some of the survivors of the 133rd IR.
