I know there are s few posts on Monte Cassino, however I am trying to find out about a particular soldier in the Polish Division who was at the 4th battle and break through at Monte Cassino. His name was Andrzej Jagniaszek (the grandfather of my daughter's partner). He was wounded by a bullet in North Africa (where I don't know) before the invasion of Italy. I do not know which regiment he was in. He did get some medals which are held by one of his sons. I expect I may get some information on the medals soon. However how do I go about researching his time in the Army?
