The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to First Lieutenant (Coast Artillery Corps) John Gronsky (ASN: 0-2014810), United States Army, for conspicuous gallantry and intrepidity in action against the enemy while serving with Battery B, 21st Anti-Aircraft Artillery (Automatic Weapons) Battalion (Self Propelled), 25th Infantry Division, in action near Chugang-ni, Korea, on 3 April 1951. On that date, friendly forces were advancing over a flat, open valley toward strong hostile positions near Chugang-ni. Lieutenant Gronsky preceded his half-track platoon to search for mines and to select advantageous firing positions. When three of his men were wounded by a bursting mortar shell, he exposed himself to the deadly barrage to carry them to safety. Throughout several hours of constant action, he repeatedly exposed himself to direct more effectively the movement and fire of his men and to administer to the needs of the wounded. Lieutenant Gronsky’s courageous leadership, aggressive spirit and unwavering devotion to duty enhance the high traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
