Samantha--The 229th General Hospital was located in Occupied Nagoya, Japan.
His papers show he was in the Pacific Theater (Phillippines?/Japan?) from Sept. 9, 45 to March 8, 46--so he was transferred to the hospital while in the PTO.
The 35th Infantry Regiment (25 Inf. Div.) was assigned to Japan for occupation duty on Oct. 7, 1945 where it remained active thru 1946, so I believe he was in the Phillippines for about a month and transferred to Japan. You said NARA entitled him to two stars on his Asiatic Pacific and Phillippian Liberation Medal but he was only in the PTO for seven months on occupation duty (after the war ended). Also, I've never heard of anybody going AWOL, given a Courts Marshall, and committed to eight days of hard labor and retain his rank and given an "Excellant Character" for that enlistment. (May 1937 to July 1940). I show another enlistment from 31 march, 1941 to 19 Septamber 1942 as a Pvt. without any pay or assignment, but shows he enlisted a day after his seperation (19 Sept. 1942) as a PFC and servrd 2yrs, 11mts 24 days on a regular enlistment. I don't blame you for being confused--good luck on your search--I've got a headache..
