I don't have much for you right now. I can provide you with a brief history of your Dad's unit, the 1876th. Engineer Aviation Battalion, as follows:
Activated 1 Mar 43 at March Field, CA; departed SFPE 22 Mar 44; arrived New Guinei 10 Apr 44; arvd. Morotai Island 16 Sep 44; arrvd. Philippines 15 Jan 45; located at Bagabag, Philippines at war's end, 15 Aug 45. inactivated 17 Jun 46 in the Philippines.
Participated in these campaigns:
14, Luzon, 15 Dec 44/4 Jul 44. 15, New Guinea, 24 Jan 43/31 Dec 44.
That is all I can gather from my primary source, which follows:
"WORLD WAR II ORDER of BATTLE", by Stanley L. Shelby, published by Galahad Books, NYNY.
I have other sources books and will pass along anything new I might come up with, without charge, of course.
