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.

Flank: Used as a noun, a "flank" is the end (or side) of a military position, also called a "wing". An unprotected flank is "in the air", while a protected flank is a "refused flank". Used as a verb, "to flank" is to move around and gain the side of an enemy position, avoiding a frontal assault.

Minie Bullet (or minié bullet): (pronounced min-ee or min-ee-ay) The standard infantry bullet of the Civil War. The bullet was designed for muzzle-loading rifle-muskets. It was invented by two Frenchmen, Henri-Gustave Delvigne and Claude-Étienne Minié (pronounced "min-ee-ay"). It was small enough to load quickly, and had a special feature that let it take advantage of a rifled-barrel. When the rifle-musket was fired, expanding gas from the gunpowder blast was caught in the hollow base of the bullet forcing it against the rifled grooves inside the barrel.
