The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Silver Star (Posthumously) to First Lieutenant (Infantry) Timothy Tai Sun Eum (ASN: 0-956841), United States Army, for gallantry in action against the enemy as a member of Battery A, 674th Airborne Field Artillery Battalion, 187th Regimental Combat Team, 11th Airborne Division, in action in the vicinity of Samdung, Korea. On 1 December 1950, Lieutenant Eum was given the mission of establishing an observation post with one squad of the Intelligence and Reconnaissance Platoon of the 187th Airborne Regimental Combat Team for the purpose of adjusting artillery fire on enemy occupied positions. When the patrol had progressed approximately 2,000 yards, enemy sniper fire was received from all sides and an estimated 20 enemy troops armed with automatic weapons launched an attack against the squad. Lieutenant Eum immediately adjusted artillery fire on the enemy and the patrol withdrew under cover of the artillery without a casualty. In addition to casualties inflicted by the artillery, the patrol killed an estimated five enemy with small-arms fire. As the patrol withdrew, it encountered fire from a group of enemy entrenched on a nearby hill. Leading an assault on the hill, Lieutenant Eum shot and wounded one enemy soldier, taking him prisoner. The prisoner later gave valuable information regarding the location and concentration of enemy troops in the area. The fearless leadership and outstanding courage of Lieutenant Eum enabled him to accomplish his mission of adjusting artillery fire on the enemy and to lead his ambushed squad back to friendly lines without the loss of a single man. The gallantry displayed by Lieutenant Eum reflected great credit on himself and the military service.
