Sorry to put put you off but my e-mail today was about three- to four times what it usually runs and I've been busier than the proverbial one-armed paperhanger. (Yeah, I know. Excuses are like armpits, etc., etc. . . .)
Looks like he may have trained, gone overseas and served with Battery A, 124th Antiaircraft Artillery (Gun) (Mobile) Battalion. Camp Callan, near La Jolla (now a suburb of San Diego), was an antiarircraft gunner training facility. He may well have joined Battery A at Camp Haan, near Riverside. From there, the entire battalion went to the Boston Area, where it staged for overseas deployment (Arlington is just out of Boston and was one of several staging areas for the Boston Port of Embarkation). The battalion departed Boston for duty in the European Theater 1 July 1944 and arrived in England on the 8th, where they equipped and trained prior to landing in France 25 September 1944. 124th returned to the U. S. in October 1945. This is about when he would have been transferred to the 217th (transferred out and replaced by a "high points" man from 217th or another unit - see paragraph 4 of Message #6148). 217th returned to the U. S. December 1945 - January 1946. Battalion Headquarters arrived at Hampton Roads, Virginia 2 January 1946 and the entire battalion was inactivated the same date. Decorations: none. Campaign Participation Credits: Rhineland, Ardennes-Alsace and Central Europe. IMPORTANT. All the above is merely an educated guess. The only way to determine for certain is to access official records (that's called a "disclaimer"; it means, essentially, "If you use it, don't put my name on it" - just kidding).
