The hunt is off to a good start.
He belonged to C Company, 141st Infantry (First Texas), 36th Infantry Division. Appears to have been wounded in action. More to come hopefully.
A bit of background on where he served and fought overseas.
OVER THERE: The regiment sailed from New York on July 26, 1918, after intensive training at Camp Bowie. Arriving in France on August 6, it was assigned to the 13th Training area near Bar sur Aube. After moving into support positions in September, it was assigned to prepare to relieve the 2d U. S. Division in the Epernay-Chalons region. With the 142d Regiment, they took over the positions of the 9th and 23d U. S. Infantry regiments.
IN THE LINES: On October 8, 1918, the regiment began participation in one of the great chapters in its combat history, the Meuse-Argonne campaign. On that day, along a line extending four kilometers east to west, the 141st and 142d regiments attacked German positions, resulting in a "substantial gain of ground" but suffering casualties to sixty-six officers and 1,227 enlisted men. After being relieved by the 72d Brigade (143rd and 144 Inf), the unit side-stepped to take a place at the east end of the line of the 72d Brigade several days later. On October 27, the unit took part in the assault on "Foret (Forest?) Farm", and then was relieved on October 28th, taking no further combat action in the war. The unit returned to the United States after six additional months in France and was mustered out July 3, 1919.
