The mission was cut short when one of the Cochinos 4,000-pound batteries caught fire. Benitez directed the firefighting, trying both to save the ship and his crew from the toxic gases. The crew members of the Tusk rescued all except one Cochino crew member and convinced Benitez, who was the last man on the Cochino, to board the Tusk. The Cochino sank off the coast of Norway two minutes after Benitez's departure. Benitez retired from the Navy in 1957 as a rear admiral. Korean War Sixty-one thousand Puerto Ricans served in the Korean War, including 18,000 Puerto Ricans who enlisted in the continental United States. On August 26, 1950, the 65th Infantry Regiment departed from Puerto Rico and arrived in Pusan, Korea on September 23, 1950. It was during the long sea voyage that the 65th Infantry was nicknamed the "Borinqueneers". The name is a combination of the words "Borinquen" (the Taíno name for Puerto Rico) and "Buccaneers". Among the hardships suffered by the Puerto Ricans after they arrived in Korea was the lack of warm clothing during the cold, harsh winters. The enemy made many attempts to encircle the regiment, but each time they failed because of the many casualties inflicted by the 65th. In December 1950, U.S. Marines found themselves at the Chosin Reservoir area. The 65th was part of a task force which enabled the Marines to withdraw from Hangu-Ri. In December 1952, 162 Puerto Ricans of the 65th Infantry were arrested, 95 were court-martialed, and 91 were found guilty and sentenced to prison terms ranging from 1 to 18 years of hard labor. It was the largest mass court martial of the Korean War. The Secretary of the Army Robert T. Stevens moved quickly to remit the sentences and granted clemency and pardons to all those involved. Though the men who were court-martialed were pardoned in 1954, a campaign was later started to obtain a formal exoneration. Among the battles and operations in which the 65th participated was the Operation "Killer" of January 1951, becoming the first regiment to cross the Han River. In April 1951, the regiment participated in the Uijonber Corridor drives and in June 1951, the 65th was the third regiment to cross the Han Ton River. Master Sergeant Juan E. Negrón received the Medal of Honor posthumously on March 18, 2014, for his courageous actions while serving as a member of Company
