Question: When was the last pow released from vietnam?

Disambiguated questions and answers:
context: Following the Paris Peace Accords of January 1973, U.S. prisoners of war were returned during Operation Homecoming during February through April 1973. During this, 591 POWs were released to U.S. authorities; this included a few captured in Laos and released in North Vietnam. U.S. President Richard Nixon announced that all U.S. servicemen taken prisoner had been accounted for. At that time, the U.S. listed 2,646 Americans as unaccounted for, including about 1,350 prisoners of war or missing in action and roughly 1,200 reported killed in action and body not recovered. The low numbers of returnees from Laos caused some immediate concern, as previous Pentagon estimates were as high as 41 for prisoners held there, although only a few had been known to be captured for certain. By late 1973, the remains of over 700 Americans killed in Southeast Asia had been returned and identified.

Long-form answers:
knowledge: content: American POWs in North Vietnam were released in early 1973 as part of Operation Homecoming, the result of diplomatic negotiations concluding U.S. military involvement in Vietnam. On February 12, 1973, the first of 591 U.S. prisoners began to be repatriated, and return flights continued until late March. After Operation Homecoming, the U.S. still listed roughly 1,350 Americans as prisoners of war or missing in action and sought the return of roughly 1,200 Americans reported killed in action, but whose bodies were not recovered.[2] These missing personnel would become the subject of the Vietnam War POW/MIA issue.
