Thanks for your nice response..."old dogs appreciate a pat on the head"...and all that.
Your dad's unit 938th FA BN, would have probably been under II Corps for the landing at Oran, Algeria, and fired in support of the 34th Infantry Division, which I believe was the first ID to engage the Germans in North Africa.
As for his transport, I can confirm that the USS MONTECELLO was formerly the Italian liner, CONTE GRANDE, before it was taken over by the US at the outset of the war.
This confirmation is based on a brief history of the 456th Engineer Depot Company.
My late brother-in-law, ELVIE DECKER WRIGHT was a member of that unit, and sailed on the MONTECELLO, enroute to the China-Burma-India theater, where it participated in the construction of the LEDO ROAD, the ultimate savior of China.
Mr. Adams may have been "exposed" to my 985th FA BN, for it too was a 155mm howitzer battalion, and was in North Africa, but it was there only for training purposes, and did not fight there.
