Andrew, My Grandfather served with the 432nd AAA Bn (AW)(SP)Btry B. Capt Phelps was the Chaplin for the Battalion. They served in Algeria, Tunisia, and Italy. In Notrh Africa, they mostly protected airfields and ports. Next, They landed in Naples, Italy and worked their way up to Po Valley by the end of the war.
If you are interested, I have a very interesting diary that was published in the Bartlesville, OK newspaper that was written by Capt. Phelps's assistant. It tells the day to day life in good detail. I can share if your are interested.
