The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Lieutenant Arthur H. G. Mallet, Army of France, for extraordinary heroism in action while serving as Liaison Officer, 2d Battalion, 47th U.S. Infantry (Attached), 4th Division, A.E.F., on the Vesle River, near Bazoches, France, 7 August 1918, while serving as liaison officer with the 2d Battalion, 47th U.S. Infantry, which led the attack against the enemy in the face of stubborn resistance, crossed the Vesle River, seized a critical position north of that stream, and held tenaciously to it throughout the day. Lieutenant Mallet, under a heavy and continuous hostile fire, repeatedly went from one front-line combat group to another, assisting materially in the successful conduct of the action by his courageous actions, suggestions, and professional skill. He rendered highly important services at a critical moment when the left of the line was sorely pressed by enemy counterattack and at all times by his soldierly conduct, inspiring courage, and high qualities of leadership was an heroic example to his comrades in arms. He was killed in action late in the afternoon.
