The longest-serving enlisted prisoner of war in American history marked 40 years of freedom this weekend.
Bill Robinson, who now lives in East Tennessee, spent the bulk of his twenties at the infamous Hanoi Hilton in North Vietnam.
A militia captured Robinson and his team in 1965 while they were trying to rescue a downed pilot. The North Vietnamese military held him captive for seven-and-a-half years. He braved mental torture and endured physical pain before he was rescued in February 1973.
This weekend, the Air Force Enlisted Heritage Research Institute dedicated a POW-MIA exhibit in Robinson's honor. That's in Montgomery, Alabama.
The Air Force veteran and five other POWs shared their experiences.
"Thank you for being here for me and my family. As we continue to move forward in the next 40 years, hopefully we'll never have to do this again for a younger generation of Americans," Robinson said.
We profiled Robinson's story in 2010 as part of our Service and Sacrifice series. You can watch part one here and part two here.
Robinson is also about to finish his book. It should be out this summer.
