Michael, I don't have info on your grandfather's unit, but I'm basically looking for similar stuff about my father who was a surgeon in the 179th general hospital. All I know is that it went through Omaha Beach, set up a field hospital at Carenton, and then ended up in Rouen, until the occupation. I will keep your hospital in mind as I search, if you will do the same for me. There doesn't seem to be much on medical units at all out there. Thanks!
