World War II came to Arizona via two significant avenues: prisoner-of-war camps and military training bases. Notorious for its prisoners' attempted escape through the Faustball Tunnel, Papago POW Camp also had a dark reputation of violence among its prisoners. An unfortunate casualty was Werner Drechsler, who supplied German secrets to U.S. Navy authorities after his capture in 1943. Nazis held there labeled him a traitor and hanged him from a bathroom rafter. Controversy erupted over whether the killing was an act of war or murder, as well as the lack of protection Drechsler received for aiding in espionage. Ultimately, seven POWs were hanged for the crime. Author Jane Eppinga examines the tangled details and implications of America's last mass execution.
