Hi Angela
The 7th Batt was a home based battalion which did not enter combat until after D-Day.
The First Army, in WW2, was specifically created for the landings in North Africa, and so one won't really learn much about them before his capture (which was early in the campaign).
However, a good introduction to the subject is Desperate Venture: The Story of Operation Torch by Norman Gelb. Now, if I could just find my copy I will look up any details.
