These clothes were worn by U.S. Army Special Forces Staff Sgt. Jon R. Cavaiani as a prisoner of war in North Vietnam. Cavaiani, imprisoned in the notoriously brutal “Hanoi Hilton,” was held captive from June 1971 to March 1973. He received the Medal of Honor for protecting his comrades in events that led to his capture. / Scott Metzler, National Museum of the United States Army
