Tuol Sleng Genocide Museum - Prison Staff

The interrogation unit was split into three separate groups: Krom Noyobai or the political unit, Krom Kdao or the hot unit and Krom Angkiem, or the chewing unit. The hot unit (sometimes called the cruel unit) was allowed to use torture. In contrast, the cold unit (sometimes called the gentle unit) was prohibited from using torture to obtain confessions. If they could not make prisoners confess, they would transfer them to the hot unit. The chewing unit dealt with tough and important cases. Those who worked as interrogators were literate and usually in their 20s.

U.S. Sanitary Commission: A government agency created on June 18, 1861, whose purpose was to coordinate female volunteers who were supporting the Federal army. These women collected over $25 million in donations from "Sanitary Fairs" and other fundraisers. The volunteers also made uniforms and bandages, worked as cooks, and nursed the sick and wounded. Leadership, however, was largely male.

Smoothbore: A gun is smoothbore if the inside of the barrel is completely smooth. Smoothbore guns were used before rifled guns were developed. Although smoothbores were not as accurate and had a shorter range than rifled arms, there were still plenty of them in use during the Civil War.

Secession: (pronounced si-sesh-uhn ) Withdrawal from the Federal government of the United States. Southern states, feeling persecuted by the North, seceded by voting to separate from the Union. Southerners felt this was perfectly legal but Unionists saw it as rebellion.

Territory: Land within the mainland boundaries of the country that had not yet become a state by 1861. Nevada Territory, Utah Territory, and Colorado Territory had basically the same boundaries they have today as states; Washington Territory encompassed today's states of Washington and Idaho; Dakota Territory is now the states of Montana, North Dakota, South Dakota, and the northern part of Wyoming; Nebraska Territory today is the southern part of Wyoming and the state of Nebraska; New Mexico Territory included the states of Arizona and New Mexico; and the remaining unorganized land, also called the Indian Territory, filled the approximate boundaries of Oklahoma.

Ratify: To formally approve or sanction.
