Editing Clarence Carnes (section)

== Battle of Alcatraz ==
On 2 May 1946, prisoners [[Bernard Coy]] and [[Marvin Hubbard]], who had been conspiring with Carnes to escape from Alcatraz, attacked corrections officer William Miller and beat him before using his keys to release Carnes and fellow conspirator [[Joseph Cretzer]]. They then stole several rifles and gas grenades from the gun gallery and used them to force the guards to release [[Sam Shockley]] and [[Miran Edgar Thompson]], before taking Miller and other guards hostage. However, the escape attempt failed when Coy raised the alarm after firing at prisons corrections officers but failing to kill them. Cretzer then fired on the hostages, wounding three, including Miller, who later died of his injuries. The ensuing standoff, during which a second corrections officer was killed, lasted two days until squads of armed officers managed to breach the prison and opened fire, killing Coy, Hubbard and Cretzer. Shockley, Thompson and Carnes then surrendered. They were charged with murder in the aftermath of the Battle of Alcatraz in relation to the deaths of the two corrections officers. Shockley and Thompson were sentenced to death, whereas Carnes was sentenced to 99 years on the grounds that he had, according to surviving hostages, refused to kill hostages.
