The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to First Lieutenant (Infantry), [then Second Lieutenant] John Donald Shelby (ASN: 0-885777), United States Army, for extraordinary heroism in connection with military operations against an armed enemy while serving with Company H, 2d Battalion, 16th Infantry Regiment, 1st Infantry Division, in action against enemy forces on 11 July 1943, in Sicily. In the course of a savage counterattack by some thirty enemy tanks and infantry to drive through, First Lieutenant Shelby with complete disregard for his personal safety moved to an observation post in advance of his battalion. Though subjected to intense artillery and small arms fire in his vulnerable position, he laid the fire of his mortar platoon on the enemy infantry with such devastating effect that their attack was disorganized. Though subjected to fierce tank fire, he continued to call for his own fire until the shells from his own guns were falling within one hundred and fifty yards of his position. He remained at this forward post until it was physically overrun by the enemy armor. Escaping injury, he returned to his own unit and continued the fight until the enemy withdrew with heavy losses. First Lieutenant Shelby’s inspiring leadership, personal bravery and zealous devotion to duty exemplify the highest traditions of the military forces of the United States and reflect great credit upon himself, the 1st Infantry Division, and the United States Army.
