Distingushed Service Cross citation:

The President of the United States takes pleasure in presenting the Distinguished Service Cross to John J. Cotter (0-429492), Captain (Medical Corps), U.S. Army, for extraordinary heroism in connection with military operations against an armed enemy while serving as a Medical Officer of the 116th Infantry Regiment, 29th Infantry Division, in action against enemy forces on 6 June 1944, at Normandy, France. Captain Cotter landed early in the assault upon the coast of France as part of the Regimental Medical Detachment. At this time the beach was subjected to intense enemy rifle, machine gun and artillery fire and numerous casualties had been inflicted. With complete disregard for his own safety, Captain Cotter administered medical attention to the wounded under this heavy fire. His fortitude and devotion to duty in rendering aid to the wounded under such hazardous and difficult conditions inspired those who saw him to a more determined effort in meeting the enemy. Captain Cotter's intrepid actions, personal courage and zealous devotion to duty exemplify the highest traditions of the military forces of the United States and reflect great credit upon himself, the 29th Infantry Division, and the United States Army.
