John K. Giles, a prisoner working at the Alcatraz wharf, managed to assemble a U.S. Army technical sergeant's uniform (probably from pieces stolen from bags of army laundry sent to the island to be cleaned) and board a ferry that provided service between government facilities around San Francisco Bay. Shortly after the ferry's departure for Angel Island, headcounts on the Alcatraz wharf and aboard the ferry revealed the discrepancy, and Giles was apprehended at Angel Island and returned to Alcatraz.

The most violent escape attempt occurred on May 2–4, 1946, when a failed attempt by six prisoners led to the Battle of Alcatraz, also known as the "Alcatraz Blastout". It was carried out by six prisoners: Bernard Coy, Joseph Cretzer, Sam Shockley, Clarence Carnes, Marvin Hubbard and Miran Thompson. They daringly took control of the cell house by overpowering correctional officers, and were able to enter the weapons room and obtain the keys to the recreation yard door. Their aim was to escape by boat from the dock, but when they failed to obtain the keys to the outside door, they decided to battle it out. In the fight that ensued, they managed to hold two correctional officers hostage whom they eventually killed after two days. Prompted by Shockley and Thompson, Cretzer shot the hostages at very close range. One of the guards, William Miller, succumbed to his injuries while the second guard, Harold Stites, was also killed at the cellhouse. Although Shockley, Thompson, and Carnes returned to their cells, the other three, Coy, Cretzer and Hubbard, persisted with their fight. The U.S. Marines intervened to help the correctional officers and killed the three prisoners. In this battle, apart from the guards and prisoners killed, 17 other guards and one prisoner were also injured. Shockley, Thompson, and Carnes were tried for the killing of the correctional officers. Shockley and Thompson were sentenced to death through the gas chamber, an action which was carried out at San Quentin in December 1948. However, Carnes, who was only 19 years old, was given a second life sentence.
