Was this 1944? Do you know the regiment. Do you know where else he served (ie Cassino, Anzio, Rome, etc?) I have LOADS of stuff because my grandfather served in Naples - we took him back there in 2013. (We did bring him home again......)
I have DVDs, books, photos. You name it, I've probably got it. Did he serve only in Naples or was he in the cohort that moved up to Rome?
