The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Brigadier General John Bacon McDonald, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I. While Commanding the 181st Infantry Brigade, during the advance of the 91st Division from Foret-de-Hesse, Argonne, France, in September 1918, General McDonald was instrumental in the successes achieved. He directed the attack in person, and by his example of personal courage and by his sound tactical orders he so inspired his brigade that it was enabled to capture and hold a most important position.
