Tuol Sleng Genocide Museum - Non-Cambodian prisoners

One of the last foreign prisoners to die was twenty-nine-year-old American Michael S. Deeds, who was captured with his friend Christopher E. DeLance on November 24, 1978, while sailing from Singapore to Hawaii. His confession was signed a week before the Vietnamese army invaded Cambodia and ousted the Khmer Rouge. In 1989, Deeds' brother, Karl Deeds, traveled to Cambodia in attempts to find his brother's remains, but was unsuccessful. On September 3, 2012, DeLance's photograph was identified among the caches of inmate portraits.

Traverse: A mound of earth used to protect gun positions from explosion or to defilade the inside of a field work or fortification.

Militia: Troops, like the National Guard, who are only called out to defend the land in an emergency.

Casemate: (pronounced kays-mayt) A sturdily-built, arched masonry chamber enclosed by a fortification's ramparts or walls. Casemates were often used to protect gun positions, powder magazines, storerooms or living quarters.

Cavalry: A branch of the military mounted on horseback. Cavalry units in the Civil War could move quickly from place to place or go on scouting expeditions on horseback, but usually fought on foot. Their main job was to gather information about enemy movements. Until the spring of 1863, the Confederate cavalry force was far superior to its Federal counterpart.

Sortie: A type of counter-attack used to disrupt the enemy's attack or siege of a fortification, causing the enemy to divert some of its resources away from the initial attack or siege.
