Tuol Sleng Genocide Museum - Non-Cambodian prisoners

Two Franco-Vietnamese brothers named Rovin and Harad Bernard were detained in April 1976 after they were transferred from Siem Reap, where they had worked tending cattle. Another Frenchman named Andre Gaston Courtigne, a 30-year-old clerk and typist at the French embassy, was arrested the same month along with his Khmer wife in Siem Reap.

It is possible that a handful of French nationals who went missing after the 1975 evacuation of Phnom Penh also passed through S-21. Two Americans were captured under similar circumstances. James Clark and Lance McNamara in April 1978 were sailing when their boat drifted off course and sailed into Cambodian waters. They were arrested by Khmer patrol boats, taken ashore, where they were blindfolded, placed on trucks, and taken to the then-deserted Phnom Penh.

Earthwork: A field fortification (such as a trench or a mound) made of earth. Earthworks were used to protect troops during battles or sieges, to protect artillery batteries, and to slow an advancing enemy.

Federal: Loyal to the government of the United States. Also known as Union, Yankee, or Northern.

Housewife: Small sewing kit soldiers used to repair their garments.

"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.

Rebel Yell: A high-pitched cry that Confederate soldiers would shout when attacking. First heard at First Manassas (First Bull Run) Union troops found the eerie noise unnerving.
