Tuol Sleng Genocide Museum - Non-Cambodian prisoners

Twenty-six-year-old John D. Dewhirst, a British tourist, was one of the youngest foreigners to die in the prison. He was sailing with his New Zealand companion, Kerry Hamill, and their Canadian friend Stuart Glass when their boat drifted into Cambodian territory and was intercepted by Khmer patrol boats on August 13, 1978. Glass was killed during the arrest, while Dewhirst and Hamill were captured, blindfolded, and taken to shore. Both were executed after having been tortured for several months at Tuol Sleng. Witnesses reported that a foreigner was burned alive; initially, it was suggested that this might have been John Dewhirst, but a survivor would later identify Kerry Hamill as the victim of this particular act of brutality. Robert Hamill, his brother and a champion Atlantic rower, would years later make a documentary, Brother Number One, about his brother's incarceration.

Monitor: Originally, the U.S.S. Monitor, the first ironclad warship in the United States Navy, commanded by Admiral John L. Worden. The vessel had a large, round gun turret on top of a flat raft-like bottom, which caused some spectators to describe it as a "cheesebox on a raft." The first engagement between ironclads occurred on March 8-9, 1862, at the Battle of Hampton Roads, VA, when the U.S.S. Monitor fought the C.S.S. Virginia (formerly the U.S.S. Merrimack). Eventually a "monitor" became the official term for an entire class of warships modeled after the original U.S.S. Monitor.

Caliber: The distance around the inside of a gun barrel measured in thousands of an inch. Bullets are labeled by what caliber gun they fit.

Breach: A large gap or "hole" in a fortification's walls or embankments caused by artillery or mines, exposing the inside of the fortification to assault.

States Rights: This doctrine held the powers of the individual states as greater than the powers of the Federal government. States rights meant that the Federal government held its power only through the consent of the states and that any powers not specifically given to the Federal government remained in control of the states.

Long Roll: A long, continuous drum call which commanded a regiment to assemble.
