On This Day - What happened 11 June 1962 AD

Frank Lee Morris (September 1, 1926 – disappeared June 11, 1962) was born in Washington, D.C.[19] He was abandoned by his mother and father during his childhood, and orphaned at age 11, The Anglin brothers, John William (May 2, 1930 – disappeared June 11, 1962) and Clarence (May 11, 1931 – disappeared June 11, 1962) were born into a family of thirteen children in Donalsonville, Georgia. Their parents, George Robert Anglin and Rachael Van Miller Anglin, were seasonal farmworkers; in the early 1940s, Allen Clayton West (March 25, 1929 – December 21, 1978) was born in New York City. He was imprisoned for car theft in 1955, first at Atlanta Penitentiary, then at Florida State Prison. After an unsuccessful escape attempt from the Florida facility, he was transferred to Alcatraz in 1957 and became inmate AZ1335.

On the night of June 11, 1962, with all preparations in place, the men began their escape. However, the cement employed to shore up crumbling concrete around West's vent had hardened, diminishing the hole in size and fixing the grill in place. By the time he managed to remove the grill and re-widen the hole to egress, the others had already left, as he was soon to discover; he busted out to the prison roof only to return to his cell around sunrise and go to sleep. West went on to cooperate fully with investigators and give them a detailed description of the escape plan, in consequence of which he was not punished for his role in it.

From the service corridor, Morris and the Anglins climbed the ventilation shaft to the roof. Guards heard a loud crash as they broke out of the shaft, but since nothing further was heard, the source of the noise was not investigated. Hauling their gear with them, they descended 50 feet (15 m) to the ground by sliding down a kitchen vent pipe, then climbed two 12-foot (3.7 m) barbed-wire perimeter fences. At the northeast shoreline, near the power plant—a blind spot in the prison's network of searchlights and gun towers they inflated their raft with the concertina. At some time after 10 p.m., investigators estimated, they boarded the raft, launched it and departed toward their objective, Angel Island, two miles to the north.
