April 1972. Air Force navigator Lt. Col. Iceal Hambleton is shot down behind North Vietnamese lines during the Easter Offensive. The air rescue attempts are a catastrophe. Five more aircraft are lost and at least 11 more airmen are killed trying to reach him. So the Navy sends one SEAL, Lt. Tom Norris, with five South Vietnamese commandos, to go get him on foot. One of them was Petty Officer Nguyen Van Kiet, a 27-year-old frogman from the South Vietnamese Navy. They rescued one downed pilot from the river first. But as they pushed deeper to reach Hambleton, two of the commandos refused to go on. They would not risk their lives following an American to save an American. Norris was ready to go alone. Kiet volunteered to go with him. On the night of April 12, the two men found a deserted village, put on local fishermen's clothes, and took an abandoned sampan up the river in thick fog. North Vietnamese troops and tanks lined the shore. They rowed right past Hambleton in the dark and came out under the Cam Lo bridge. They turned around and found him in a clump of bushes, alive but half delirious after 11 days behind enemy lines. The sun was coming up. They hid him in the bottom of the boat under bamboo and started back downriver in daylight. North Vietnamese soldiers spotted them and opened fire. Kiet pulled the sampan behind a riverbank and hid it while Norris called in air strikes. They made it out. Norris received the Medal of Honor. Kiet received the Navy Cross, the only South Vietnamese sailor ever awarded it. He later moved to Seattle, became an American citizen, and worked at Boeing for nearly 20 years.
