Son of John Home Chiles of Denver. Entered service from Colorado. Member Company A, 356th Infantry Regiment, 89th Division. Awarded Medal of Honor for his actions as part of the Meuse-Argonne Offensive when, 4 days after being promoted to Captain, according to the Medal of Honor citation: "When his battalion, of which he had just taken command, was halted by machine-gun fire from the front and left flank, he picked up the rifle of a dead soldier and, calling on his men to follow led the advance across a stream, waist deep, in the face of the machinegun fire. Upon reaching the opposite bank this gallant officer was seriously wounded in the abdomen by a sniper, but before permitting himself to be evacuated he made complete arrangements for turning over his command to the next senior officer, and under the inspiration of his fearless leadership his battalion reached its objective. Capt. Chiles died shortly after reaching the hospital."
