One of the bloodiest battles in the history of American prisons occurred at Alcatraz in May 1946, when prisoners staged a breakout, obtaining guns from the gun gallery and taking nine guards hostage. The escape attempt was the culmination of months of methodical planning. But, when a last-minute glitch foiled their escape, inmates shot the hostages in effort to leave no witnesses. Before order was restored, thousands of rounds were fired by federal prison personnel and a detachment of the U.S. Marines. Among the guards who survived the shooting was Ernie Lageson, Sr. the author's father. Now in Battle at Alcatrz, author Ernie Lageson Jr. passes on his father's story. Meticulously researched, this compelling story offers an insider's perspective on both the notorious riot and life inside the most infamous prison in America. Eight pages of photos.
