No 2 Commando in Italy - Ravenna/Argenta

Hi my father Eric Groves MM was stationed in Ravenna in April 1945 and was awarded the MM for an incident that happened nearby in Argenta (more details on this profile page). Dad took me there when I was younger so I have got some places to visit in mind but I am soon to be travelling to Ravenna with his grandchildren and wondered if there was a good source of info about their activities there or any actual contacts in Italy? Any info or help appreciated!
