The only prison with hot showers: The showers at Alcatraz were always supplied with moderately hot water, in order to hinder inmates from becoming acclimated to the cold Bay waters.
One successful escape in 29 years: Out of 14 attempts in the history of the prison, only one successful escape has been recorded, that of the Anglin brothers and Frank Morris in 1962.
The Hopi resistence: The Hopi Hostiles were a group of 19 Hopi men (a native-American tribe) who were imprisoned on Alcatraz when it was still under military control.
Incarceration didn't work: The government figured that hard labor and confinement would eventually force them to submit, and they were held from January to August of 1895.
