Northern Solomons, 22 Feb 43/21 Nov 43;
Luzon, 15 Dec 44/4 Jul 45.
** I note that he did not get combat credit for the Central Pacific Campaign, which suggests that he joined later, possibly as a replacement on Guadacanal.He was not present for Pearl Harbor Day, 7 Dec 41.
Wounded in Action 4,190
Died from Wounds, 262.
Location at war's end, 15 Aug 45:
Bambam, Philippine Islands.
Per your Check List...
1. I take it that he was discharged as a Staff Sgt.,
at Camp Bealle, CA, 28 Aug 45.
5. Army of the United States
30/31. He was a mechanic, working with motor vehicles as opposed to tanks and cannons etc, which were the responsibility of the Ordance personnel.
He had qualified for the Combat Infantry Badge by virtue of havng fired his weapon in combat, I presume.
32. These were separate campaigns, as indicated by the above.
The Asiatic-Pacific Campaign Ribbon bears three bronze stars, representing each of the three campaigns listed on his discharge.
36. My impression is that he departed the states 17 Dec 41, and arrived A-P Theater, 24 Dec 41.
Bythe same reasoning, I believe he left A-P, 24 May 45, and arrived US, 17 Jun 45.
40. The war was winding down, and this Army Regulation was issued to pave the way for return to civilian status.
55.This was a bronze lapel pen, in the shape of an eagle,
which was then translated into Ruptured Duck, a label which still prevails.
This is sort of wordy, probably more than you expected.
Stanton's ORDER of BATTLE provides insight into the individual combat activities of the Regiments.
I hope it helps in your quest for more light.
