U.S. Navy Medal of Honor citation of Gunnery Sergeant Ernest August Janson, USMC -- Served under name of Charles Hoffman -- (as printed in the official publication "Medal of Honor, 1861-1949, The Navy", page 118):

"For conspicuous gallantry and intrepidity above and beyond the call of duty in action with the enemy near Chateau-Thierry, France, 6 June 1918. Immediately after the company to which Gunnery Sergeant Janson belonged, had reached its objective on Hill 142, several hostile counterattacks were launched against the line before the new position had been consolidated. Gunnery Sergeant Janson was attempting to organize a position on the north slope of the hill when he saw 12 of the enemy, armed with five light machine guns, crawling toward his group. Giving the alarm, he rushed the hostile detachment, bayonetted the two leaders, and forced the others to flee, abandoning their guns. His quick action, initiative and courage drove the enemy from a position from which they could have swept the hill with machine-gun fire and forced the withdrawal of our troops."
