Alcatraz Federal Penitentiary [SEP] Battle of Alcatraz
The most violent escape attempt occurred on 2–4 May 1946, when a failed attempt by six prisoners led to the Battle of Alcatraz, also known as the "Alcatraz Blast out". Bernard Coy, Joseph Cretzer, Sam Shockley, Clarence Carnes, Marvin Hubbard and Miran Thompson daringly took control of the cell house by overpowering correctional officers, and were able to enter the weapons room, where they then demanded keys to the outside recreation door. A quick-thinking guard, William Miller, turned over all but the key to the outer door, which he pocketed. The prisoners' aim was to escape by boat from the dock, but when they were unable to open the outside door, they decided to battle it out.
