The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to First Lieutenant (Infantry), [then Second Lieutenant] Charles I. Caldwell (ASN: 022034500), United States Army, for gallantry in action as a member of Headquarters, 6th Infantry Division (then Headquarters, 9th Infantry Regiment,) 2d Infantry Division, in action against an armed enemy on 31 August 1950 in the vicinity of the Naktong River, Korea. On that date, the 9th Infantry Regiment was holding its sector of the defense line when the enemy succeeded in crossing the river with a numerically superior force, penetrating friendly lines and driving them to the rear, isolating many friendly front line units. Captain Caldwell, with a number of men from several companies of the regiment, were one group thus cut off. Under his direction, they set up a perimeter and held their ground for five days. The enemy launched vicious attacks daily in the early dawn and just after dark. The group, having exhausted its ammunition, replenished its supply from the enemy dead. Finally due to lack of food, water, and ammunition, Captain Caldwell was forced to order the evacuation of the position, instructing the men to infiltrate through the enemy lines in small groups. While working his own way to the rear, Captain Caldwell was captured by the enemy, struck over the head, stripped of his shoes and clothing and left for dead. Upon regaining consciousness, he fearlessly worked his way to the rear, a journey of some three days, without food and clothing, finally rejoining elements of the Regiment. The heroic example set by Captain Caldwell in the courageous defense of the position was in keeping with the highest traditions of the military service.
