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.

Private: The lowest rank in the army.

Works: Fortified structures designed to strengthen a position in battle. This includes earthworks, fieldworks, entrenchments, siege lines, etc.

Mason-Dixon line: A boundary surveyed in the 1760s that ran between Pennsylvania to the North and Delaware, Maryland and (West) Virginia to the South. It became a symbolic division between free states and slave states.

Howitzer: A cannon which fired hollow projectiles and was generally lighter and shorter than its solid-shot cousins. A howitzer's projectiles had a smaller powder charge. Also, canister projectiles contained more small balls than other types of canister. Howitzers were useful in defending fortifications and causing disorder within with in an attacking force.

Battery: The basic unit of soldiers in an artillery regiment; similar to a company in an infantry regiment. Batteries included 6 cannon (with the horses, ammunition, and equipment needed to move and fire them), 155 men, a captain, 30 other officers, 2 buglers, 52 drivers, and 70 cannoneers. As the War dragged on, very few batteries fought at full strength. A battery can also be the position on a battlefield where cannon are located.
