He was awarded the Congressional Medal of Honor (posthumously) and his citation reads as follows:
For conspicuous gallantry and intrepidity above and beyond the call of duty in action with the enemy near Le Champs Bas, France, November 3, 1918. When his battalion, of which he had just taken command, was halted by machinegun fire from the front and left flank, Captain Chiles 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 machine gun 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. He died shortly after reaching the hospital.
Marcellus Holmes Chiles was buried in the Argonne American Cemetery, Plot C Row 31 Grave 23, Romagne Sout-Mont-Fancon, Department of Meuse France. A current picture of the Cemetery is available on the The American Battle Monuments Commission website.http://www.abmc.gov/cemeteries/cemeteries/ma.php
