Tuol Sleng Genocide Museum - Non-Cambodian prisoners

As of 1999, there were a total of 79 foreign victims on record, but former Tuol Sleng Khmer Rouge photographer Nim Im claims that the records are not complete. On top of that, there is also an eyewitness account of a Cuban and a Swiss who passed through the prison, though no official records of either are shown.

Republican Party: A political party created in the 1850s to prevent the spread of slavery to the territories. Eventually Republicans came to oppose the entire existence of slavery. Abraham Lincoln was the first Republican president. Very few Southerners were Republicans.

Conscript: A draftee. The military draft became a necessity on both sides of the conflict. While many conscripts were excellent soldiers, veterans often considered draftees to be inferior, unreliable soldiers. Towns often posted pleas for volunteers in order to "avoid the draft".

Artillery: Cannon or other large caliber firearms; a branch of the army armed with cannon.

Caliber: The distance around the inside of a gun barrel measured in thousands of an inch. Bullets are labeled by what caliber gun they fit.

Breech-loading: Rifle-muskets that could be loaded at the breech (in the middle between the barrel and the stock) instead of from the end (by shoving gunpowder and a ball down the barrel) were called breech-loading guns.
