Legion of Merit Citation

The President of the United States of America takes pleasure in presenting the Legion of Merit with Combat "V" to Lieutenant Colonel Thomas L. Ridge (MCSN: 0-5833), United States Marine Corps, for exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States while serving as Commanding Officer of a Marine infantry battalion in Korea from 26 November to 10 December 1950.

During the Chosin Reservoir operations, Lieutenant Colonel Ridge demonstrated extraordinary skill, initiative, and determination. His battalion was assigned a critical sector of the defense at Hagaru-ri from 27 November to 7 December 1950, and he served as Defense Area Commander from 28 November to 5 December 1950.

With complete disregard for personal safety and fatigue, he so expertly employed his reinforced battalion that determined enemy attacks were repelled, and the defense perimeter remained intact despite repeated enemy efforts to overrun the garrison. His leadership was instrumental in allowing other divisional units to reorganize and resupply, and in establishing a base for the treatment and evacuation of casualties.

In the subsequent attacks on Koto-ri and Chinhung-ni, Lieutenant Colonel Ridge continued the skillful employment of his battalion, inflicting heavy losses on the enemy, inspiring his Marines to extraordinary effort, and materially contributing to the division’s operational success.

Lieutenant Colonel Ridge’s exceptional leadership, tactical acumen, and unwavering dedication reflect the highest traditions of the United States Naval Service. (He is authorized to wear the Combat "V.")

Bronze Star Citation For meritorious service in connection with operations against the enemy while serving as commanding officer of a Marine infantry battalion in KOREA from 28 October 1950 to 14 November 1950. Assigned the independent mission of establishing a defensive position at Majon-ni to deny the enemy the use of this important road hub, Lieutenant Colonel RIDGE expertly retained tactical control of his battalion despite opposition by numerically superior enemy forces, by the skillful employment of combat patrols, reconnaissance in force, and the use of supporting arms. In addition, by emphasising the employment of his intelligence agencies, and as a result of a sound civil affairs program which won the support of the native population, he was able to obtain an unusual volume of intelligence information, which permitted the establishment of the defensive position deep in enemy territory. When enemy forces cut the main supply route to his rear, completely surrounding his position, he skillfully coordinated the air dropping of essential supplies, and on two occasions elements of his battalion fought their way through enemy roadblocks with supplies. During the course of the action, a total of 1395 prisoners of war were taken, and heavy casualties were inflicted on the enemy. His sound and inspiring leadership and thorough knowledge of the problems involved resulted in the successful completion of his mission. Lieutenant Colonel RIDGE's exemplary and meritorious conduct throughout was in keeping with the highest traditions of the United States Naval Service.

Lieutenant Colonel RIDGE's actions throughout were in keeping with the highest traditions of the United States Naval Service.
