behind enemy lines. Assisted by Vietnamese Sea Commando forces, he and Republic of Vietnam Navy Petty Officer Nguyen Van Kiet went more than behind enemy lines and successfully rescued two of the downed American aviators. Walker was discovered and killed by the North Vietnamese Army. Though Norris at first rejected the honor, he was recognized with the Medal of Honor in 1975. Intelligence gathering mission Six months later, on October 31, 1972, Norris and fellow Navy SEAL Michael E. Thornton accompanied three South Vietnamese special forces soldiers on an intelligence gathering operation south of the demilitarized zone. They intended to reconnoiter the area around the Cửa Việt Base near the coast of Quảng Trị Province, just south of the Demilitarized Zone. Approaching by sea, the group was transported by junk until sunset, then paddled a rubber boat to within a mile of shore and swam the remaining distance. Moving inland past numerous North Vietnamese encampments, the group reconnoitered through the night. When morning dawned, the 5-man group realized that they had landed to the north and were actually in North Vietnam. They soon encountered a two-man North Vietnamese patrol, which the South Vietnamese attempted to capture. Instead, enemy troops were alerted to their position. For the next four hours, the five men held off an enemy force estimated at about 200–300 strong. Norris called in naval firepower on the enemy's positions, helping to keep them alive. The North Vietnamese regrouped and surrounded the troops. The SEALs and South Vietnamese decided to withdraw. Norris protected their rear while the others moved towards the water. He was shot in the head and severely wounded. One of the South Vietnamese who saw Norris' wound assumed he was dead. Thornton, upon hearing the news, ran through heavy fire to recover the body of his fallen comrade, only to discover that Norris was still just barely alive. He killed several North Vietnamese as they surmounted the dunes around his position and then carried the unconscious Norris into the water. Thornton also carried one of the South Vietnamese soldiers who had been wounded and was unable to swim into the ocean. Thornton swam and supported the two injured men for more than two hours before they were picked up by the same junk that had dropped them off the night before. Norris' first surgery lasted 19 hours. Thornton was recognized with the Medal of Honor for
