Operation Glory was an American effort to repatriate the remains of United Nations Command casualties from North Korea at the end of the Korean War. The Korean Armistice Agreement of July 1953 called for the repatriation of all casualties and prisoners of war, and through September and October 1954 the Graves Registration Service Command received the remains of approximately 4,000 casualties. Note: the calculation of remains comes from Coleman as the "Historical Summary" gives a total of 4,023 UN remains received.But see: Not all remains were returned to the home countries. Some of the 2,300 remains buried at the United Nations Memorial Cemetery in Busan, South Korea were recovered during Operation Glory. Of the 1,868 American remains, 848 unidentified remains were buried as "unknowns" at the National Memorial Cemetery of the Pacific in Hawaii.
Some of the remains came from the temporary military cemeteries in North Korea that had been abandoned as Chinese forces pushed US forces out of North Korea. Public ceremonies involving delivery of the returned remains included honor guards. Also exchanged were the remains of approximately 14,000 North Korean and Chinese casualties.
