Tuol Sleng Genocide Museum

Other rooms contain only a rusting iron bedframe, beneath a black and white photograph showing the room as it was found by the Vietnamese. In each photograph, the mutilated body of a prisoner is chained to the bed, killed by his fleeing captors only hours before the prison was captured. Other rooms preserve leg-irons and instruments of torture. They are accompanied by paintings by former inmate Vann Nath showing people being tortured, which were added by the post-Khmer Rouge regime installed by the Vietnamese in 1979.

"Infernal Machine": A term of contempt for torpedoes (either the land or the water variety). This term was also used to describe the Confederate vessel H.L. Hunley- the first successful submarine.

Breastworks: Barriers which were about breast-high and protected soldiers from enemy fire.

Cartridge: Roll of thin paper which held a small amount of gun powder in the bottom and a ball or bullet in the top. A soldier needed to tear off the top of the cartridge in order to fire his weapon - part of the nine steps to fire a muzzle loading gun (or five to fire a breech loading gun).

Rifle-Musket: The common weapon of the Civil War infantryman, it was a firearm fired from the shoulder. It differed from a regular musket by the grooves (called rifling) cut into the inside of the barrel. When the exploding powder thrusts the bullet forward, the grooves in the barrel make it spin, just like a football spirals through the air. Rifle-muskets were more accurate and had a longer range than smoothbore weapons.

Chevaux-de-Frise: (pronounced sheh-VOH-de-freez) A defensive obstacle constructed by using a long horizontal beam pierced with diagonal rows of sharpened spikes. When several cheval-de-frise (singular, pronounced she-VAL-de-freez) were bolted together they created an effective barrier for roads and fortifications.
