In May of 1946, Alcatraz Federal Penitentiary, located on Alcatraz Island in San Francisco Bay, witnessed one of the most significant riots in its history. Tensions had been brewing among the inmates due to allegations of poor treatment, excess disciplinary measures, and inadequate living conditions. The situation escalated into a full-blown riot on May 2, when inmates took control of parts of the prison, took hostages, and clashed with guards. As the riots continued for two days, the extent of the violence led to the deaths of five individuals, including both inmates and prison officers, raising the stakes of the situation further.To bring the escalating situation under control, U.S. Marines from the nearby Treasure Island Naval Base were summoned, marking an unprecedented instance of military intervention in a domestic penitentiary crisis. On May 4, the Marines utilized their training and skills to safely and effectively quell the uprising. Their involvement highlighted the complexities surrounding prison management, inmate rights, and the response to violent uprisings in correctional facilities. Within a few hours, order was restored, and the incident became a point of reference for discussions around the treatment of inmates and the justice system in the years to follow.
