L, 65th Infantry Regiment, 3d Infantry Division during combat operations against an armed enemy in Kalma-Eri, Korea on April 28, 1951. The 65th helped push the advance from Ch'orwon towards P'yonggang in June and then assisted in breaking the Iron Triangle of Hill 717 in July 1951. In late November 1951, the 65th successfully fought off an attack by two battalion-sized enemy units. Colonel Juan César Cordero Dávila was named commander of 65th Infantry on February 1, 1952, thus becoming one of the highest-ranking ethnic officers in the Army. Commencing on July 3, 1952, the regiment defended the main line of resistance (MLR) for 47 days and saw action at Cognac, King and Queen with successful attacks on Chinese positions. In September 1952, the 65th Infantry was holding on to a hill known as Outpost Kelly. Chinese Communist forces that had joined the North Koreans overran the hill in what became known as the Battle of Outpost Kelly. The 65th Infantry Regiment launched several efforts to retake the position but was overwhelmed by Chinese artillery and driven off on 24 September. In October the regiment also saw action in the Cherwon Sector and on Iron Horse, around Hill 391, which became known as Jackson Heights. In June 1953, the 2nd Battalion, 65th Infantry Regiment conducted a series of successful raids on Hill 412 in support of a position called Outpost Harry, and later the regiment conducted several successful raids in addition to defending defensive positions near the base of the Iron Triangle until the armistice was signed in July. The 65th Infantry was credited with battle participation in nine campaigns. Among the distinctions awarded to the members of the 65th were a Medal of Honor, 10 Distinguished Service Crosses, 256 Silver Stars and 595 Bronze Stars. According to El Nuevo Día newspaper, May 30, 2004, a total of 756 Puerto Ricans lost their lives in Korea and a total of 3,630 men were wounded, from all four branches of the U.S. Armed Forces. More than half of these were from the 65th Infantry (not including non-Puerto Ricans). The 65th Infantry returned to Puerto Rico and was deactivated in 1956. However, Major General Juan César Cordero Dávila, Puerto Rico's Adjutant General (1958–65), persuaded the Department of the Army to transfer the 65th Infantry from the regular Army to the Puerto Rican National Guard. This was the only unit ever transferred from
