andrew,two books that will keep you amused for a while are-
world at arms by readers digest
chronicle of ww2 by longmans
both are pretty good,order them through your library,you wont find your dads particular unit in them but theres plenty of reference to the easy time your dad had.
salerno,bloodbath
sicily a nightmare
italy a graveyard
albeit your pop would have preferred D.day,my old man was in north africa and he got shipped to burma,your dad was in those who went to italy,so he must have been 8th army,your dad and mine had a hard time of it,let nobody tell you different,mack
