Tuol Sleng Genocide Museum - History

From 1976 to 1979, an estimated 20,000 people were imprisoned at Tuol Sleng (the real number is unknown). At any one time, the prison held between 1,000 and 1,500 prisoners. They were repeatedly tortured and coerced into naming family members and close associates, who were in turn arrested, tortured and killed. In the early months of S-21's existence, most of the victims were from the previous Lon Nol regime and included soldiers, government officials, as well as academics, doctors, teachers, students, factory workers, monks, engineers, etc. Later, the party leadership's paranoia turned on its own ranks and purges throughout the country saw thousands of party activists and their families brought to Tuol Sleng and murdered. Those arrested included some of the highest ranking politicians such as Khoy Thoun, Vorn Vet and Hu Nim. Although the official reason for their arrest was "espionage", these men may have been viewed by Khmer Rouge leader Pol Pot as potential leaders of a coup against him. Prisoners' families were sometimes brought en masse to be interrogated and later executed at the Choeung Ek extermination center.

Coup de Main: (pronounced koo-duh-mahn) A French term used to describe a quick, vigorous attack that surprises the enemy.

Entrenchments: Long cuts (trenches) dug out of the earth with the dirt piled up into a mound in front; used for defense.

Haversack: Small canvas bag, about one foot square, used to carry a soldier's food. Typically, these bags were painted with black tar to make them waterproof.

Rampart: A large earthen mound used to shield the inside of a fortified position from artillery fire and infantry assault. Occasionally ramparts might be constructed of other materials, such as sandbags.

Battery: The basic unit of soldiers in an artillery regiment; similar to a company in an infantry regiment. Batteries included 6 cannon (with the horses, ammunition, and equipment needed to move and fire them), 155 men, a captain, 30 other officers, 2 buglers, 52 drivers, and 70 cannoneers. As the War dragged on, very few batteries fought at full strength. A battery can also be the position on a battlefield where cannon are located.
