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.

Rifled: A gun barrel is rifled when it has grooves (called rifling) cut into the inside of the barrel for longer range and more accurate firing.

Total War: A new way of conducting war appeared during the Civil War. Instead of focusing only on military targets, armies conducting total war destroyed homes and crops to demoralize and undermine the civilian base of the enemy's war effort. (Sherman in Georgia or Sheridan in the Shenandoah Valley, for example.)

Bummer: A term used to describe marauding or foraging soldiers. Although armies on both sides often had rules against foraging or stealing from private residences, some soldiers often found ways to do so.

Instant: Used in letters and reports, "instant" referred to a particular day in the same month. For example, Robert E. Lee's Report Concerning the Attack at Harpers Ferry, written on October 19, 1859, states that Lee arrived on the "night of the 17th instant". The "17th instant" would be October 17th.

Colors: A flag identifying a regiment or army. The "Color Bearer" was the soldier who carried the flag in battle, which was considered a great honor.
