The Vietnam War was the longest conflict in America military history, lasting nearly 12 years. This also meant that those there were captured by enemy forces were held for the longest period of time. The longest-held American POW Everett Alvarez, held for nearly 8 years.
Prisoners spent days, weeks, months, and even years in solitary confinement to “reflect” on the crimes.” During this time, they were subjected to harsh interrogations and brutal beatings. They were also beaten for failing to sign “confessions” that listed their “crimes” against the Vietnamese. Often times, arms, legs, and teeth were broken, hand tied behind their backs for extended periods of time, and so on. The top right image shows the "Vietnamese rope trick" where the arms are tied together, and clamped in iron chains until the cirtulation was cut off, which often tims sprained and broke bones. For some, this went on for years.
The majority of prisoners were held at the “Hanoi Hilton” a nicknamed given my prisoners to the Hoa Lo Prison in Hanoi, North Vietnam. There were 13 other prisons throughout the region, as well as small make-shift prisons constructed by the Viet Cong (a civilian, militant militia that fought against the Americans).
