The Battle of Alcatraz, which lasted from May 2 to 4, 1946, was the result of an escape attempt at Alcatraz Federal Penitentiary by armed convicts. Two Federal Bureau of Prisons officers—William A. Miller and Harold Stites—were killed (Miller by inmate Joseph Cretzer who attempted escape and Stites by friendly fire). Three inmates were also killed during the incident.^[1] Fourteen other officers and one uninvolved convict were also injured. Two of the perpetrators were executed in 1948 for their roles.^[2]
