Tuol Sleng Genocide Museum - History

In 1979, the prison was uncovered by the invading Vietnamese army. At some point between 1979 and 1980 the prison was reopened by the government of the People's Republic of Kampuchea as a historical museum memorializing the actions of the Khmer Rouge regime.

Parrott gun: A rifled artillery piece with a reinforcing band at the rear, or breech. Parrott guns were used by both the Army and the Navy, and ranged from 10-pounders to 300-pounders. They were named after their designer, Robert Parker Parrott.

Canteen: Round container used to carry water; made of wood or tin and carried over the shoulder by a strap.

Antebellum: (pronounced an-tee-bel-uhm) A term often used to describe the United States of America before the outbreak of the Civil War.

Garrison: A group of soldiers stationed at a military post.

Revolver: A handheld firearm with a chamber to hold multiple bullets (usually 6). The chamber turns so that each bullet can be fired in succession without reloading.

The Cambodian genocide

The genocide triggered a second outflow of refugees, many of whom escaped to neighboring Thailand and, to a lesser extent, Vietnam. The Vietnamese invasion of Cambodia ended the genocide by defeating the Khmer Rouge in January 1979. In 2001, the Cambodian government established the Khmer Rouge Tribunal to try the members of the Khmer Rouge leadership responsible for the Cambodian genocide. Trials began in 2009, and in 2014, Nuon Chea and Khieu Samphan were convicted and received life sentences for crimes against humanity committed during the genocide.

Bombproof: A field fortification which was made to absorb the shock of artillery strikes. It was constructed of heavy timbers and its roof was covered with soil.

Siege: (pronounced seej) Blocking the supply lines and escape routes of a city to force it to surrender. A siege usually meant one army trapped in a city, slowly running out of food and fresh water, with the opposing army camped outside. Famous sieges were held at Petersburg, Vicksburg, and Port Hudson.

Skirmish: A minor fight.

Industry: Manufacturing goods from raw materials, such as cloth from cotton or machine parts from iron.

Spike: To make an artillery piece unusable so that it could not be used by the enemy if captured.

Tuol Sleng Genocide Museum - Non-Cambodian prisoners

Almost all non-Cambodians had left the country by early May 1975, following an overland evacuation of the French Embassy in trucks. The few who remained were seen as a security risk. Though most of the foreign victims were either Vietnamese or Thai, a number of Western prisoners, many picked up at sea by Khmer Rouge patrol boats, also passed through S-21 between April 1976 and December 1978. No foreign prisoners survived captivity in S-21.

Even though the vast majority of the victims were Cambodian, some were foreigners, including 488 Vietnamese, 31 Thai, four French, two Americans, two Australians, one Laotian, one Arab, one Briton, one Canadian, one New Zealander, and one Indonesian. Khmers of Indian and Pakistani descent were also victims.

Garrison: A group of soldiers stationed at a military post.

Green Troops: Phrase used to describe soldiers who were either new to the military or had never fought in a battle before.

Emancipation: Freedom from slavery.

Slavery: A state of bondage in which African Americans (and some Native Americans) were owned by other people, usually white, and forced to labor on their behalf.

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.

Cambodian Civil War

After Sihanouk demonstrated his support for the Khmer Rouge by visiting them in the field, their ranks swelled from 6,000 to 50,000 fighters. Many of the Khmer Rouge's new recruits were apolitical peasants who fought in support of the king, rather than communism, of which they had little understanding.

By 1975, with Lon Nol's government running out of ammunition due to its loss of U.S. support, it was clear that it was only a matter of time before it would collapse. On 17 April 1975, the Khmer Rouge captured Phnom Penh and ended the civil war. Estimates for total civil war deaths vary. Sihanouk used a figure of 600,000 civil war deaths, while Elizabeth Becker reported over a million civil war deaths, military and civilian included; other researchers were unable to corroborate such high estimates. Marek Sliwinski notes that many estimates of the dead are open to question and may have been used for propaganda, suggesting that the true number lies between 240,000 and 310,000. Judith Banister and E. Paige Johnson described 275,000 war deaths as "the highest mortality that we can justify". Patrick Heuveline states that "Subsequent reevaluations of the demographic data situated the death toll for the [civil war] in the order of 300,000 or less".

Cartridge: Roll of thin paper which held a small amount of gun powder in the bottom and a ball or bullet in the top. A soldier needed to tear off the top of the cartridge in order to fire his weapon - part of the nine steps to fire a muzzle loading gun (or five to fire a breech loading gun).

"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.

Drill: To practice marching, military formations and the steps in firing and handling one's weapon.

Torpedo Boats: Small submersible vessels with long wooden spars mounted on the bow for ramming enemy ships. Torpedoes were lashed to the tip of the spar to explode on impact.

Campaign: A series of military operations that form a distinct phase of the War (such as the Shenandoah Valley Campaign).

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.

Rifle Pit: Similar to what soldiers call a "foxhole" today. Rifle pits were trenches with earth mounded up at the end as protection from enemy fire. A soldier lay in the trench and fired from a prone position.

Typhoid: Bacterial disease causing fever, diarrhea, headache, enlargement of the spleen, and extreme physical exhaustion and collapse.

Cotton-Clad: Gunboats using stacked cotton bales to protect themselves from enemy fire.

Drill: To practice marching, military formations and the steps in firing and handling one's weapon.

Barrel: The long metal tube on a gun through which a projectile is fired.

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.

Abatis: (pronounced ab-uh-tee, ab-uh-tis, uh-bat-ee, or uh-bat-is) A line of trees, chopped down and placed with their branches facing the enemy, used to strengthen fortifications.

Dahlgren Guns: Bronze boat howitzers and rifles used by the navies which were useful in river operations. They were named after Admiral John A. Dahlgren, their inventor.

Industry: Manufacturing goods from raw materials, such as cloth from cotton or machine parts from iron.

Fascine: (pronounced fah-seen) A tightly bound bundle of straight sticks used to reinforce earthworks, trenches or lunettes. Fascines could also be used to make revetments, field magazines, fill material and blinds.

Lunette: (pronounced loo-net) A fortification shaped roughly like a half-moon. It presented two or three sides to the enemy but the rear was open to friendly lines.

Ideology

Ideology played an important role in the genocide. Pol Pot was influenced by Marxism�"Leninism and he wanted to transform Cambodia into an entirely self-sufficient agrarian socialist society that would be free from foreign influences. Stalin's work has been described as a "crucial formative influence" on his thought. Also heavily influential was Mao's work, particularly On New Democracy. Jean-Jacques Rousseau was one of his favorite authors, according to historian David Chandler (1992, p. 32). In the mid-1960s, Pol Pot reformulated his ideas about Marxism�"Leninism to suit the Cambodian situation with goals such as bringing Cambodia back to an alleged mythic past of the powerful Khmer Empire, eradicating corrupting influences, such as foreign aid and Western culture, and restoring Cambodia's agrarian society.

Pol Pot's strong belief that Cambodia needed to be transformed into an agrarian utopia stemmed from his experience in Cambodia's rural northeast�"where he developed an affinity for the agrarian self-sufficiency of the area's isolated tribes�"while the Khmer Rouge gained power. Attempts to implement these goals (formed upon the observations of small, rural communes) into a larger society were key factors in the ensuing genocide. One Khmer Rouge leader said that the killings were meant for the "purification of the populace." The Khmer Rouge virtually forced Cambodia's entire population to divide itself into mobile work teams. Michael Hunt has written that it was "an experiment in social mobilization unmatched in twentieth-century revolutions." The Khmer Rouge used an inhumane forced labor regime, starvation, forced resettlement, land collectivization, and state terror to keep the population in line. The Khmer Rouge's economic plan was aptly named the "Maha Lout Ploh", a direct allusion to the "Great Leap Forward" of China that caused tens of millions of deaths in the Great Chinese Famine.

Torpedoes: Today called mines, Civil War torpedoes were mostly used by the Confederates. Sometimes they were buried in the ground in the enemy's path to explode when stepped on. Mostly they were used as water defenses. They floated below the surface of the water and exploded when the hull of a ship brushed against them.

Ordnance: The term used for military supplies, such as weaponry and ammunition.

Agriculture: The science of growing crops or raising livestock; farming.

Magazine: A fortified location where powder or supplies were stored.

Havelock: (pronounced hav-loc) A white cloth cover that went over a soldier's kepi, and had a long back that covered a soldier's neck and shoulders. Although it saw use in the early stages of the war, soldiers quickly learned that it cut off circulation around the head and face, leading to the eventual abandonment of the havelock.

Ethnic victims

Rooms of the Tuol Sleng Genocide Museum contain thousands of photos taken by the Khmer Rouge of their victims.
Ethnic Vietnamese, ethnic Thai, ethnic Chinese, ethnic Cham, Cambodian Christians, and other minorities were also targeted. The Khmer Rouge forcibly relocated minority groups and banned their languages. By decree, the Khmer Rouge banned the existence of more than 20 minority groups, which constituted 15% of Cambodia's population. While Cambodians in general were victims of the Khmer Rouge regime, the persecution, torture, and killings committed by the Khmer Rouge are considered an act of genocide according to the United Nations as ethnic and religious minorities were systematically targeted by Pol Pot and his regime.

Bombproof: A field fortification which was made to absorb the shock of artillery strikes. It was constructed of heavy timbers and its roof was covered with soil.

Furlough: A leave from duty, granted by a superior officer. The furloughed soldier carried papers which described his appearance, his unit, when he left and when he was due to return. Furlough papers also contained a warning that failure to return on time would cause the soldier to be "considered a deserter".

"Peculiar Institution": Another term for slavery in the South.

Musket: A smoothbore firearm fired from the shoulder. Thrust from exploding powder shoots the bullet forward like a chest pass in basketball.

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.

Cham Muslims

In February 1974, the Cham in Region 31, which is in the Western Zone of DK, protested the CPK policy which required the fishermen to register their daily catch with the local cooperative and sell them to the cooperative at a low price. At the same time, the locals were also made to buy those fishes from the cooperative at a higher price. This prompted the locals to confront the cooperative to express their discontent, only to be shot at, "killing and wounding more than 100", as one account put it. By December 1974, a rebellion by the Cham in Region 21 of the Eastern Zone had broken out against the CPK after community leaders were arrested. The rebellion was repressed forcefully by the regime with no records of casualties documented.

As much as there are records of these restrictions, resistance, and repressions, there were also accounts from the Cham community which deny the oppression by the regime between 1970 and early 1975. While restrictions on certain activities like trade and travel were in place during that period, they were understood to be by-products of the ongoing civil war. Moreover, some Cham had also joined the revolution as soldiers and members of the CPK. According to some local accounts, people had confidence in the Khmer Rouge when they first came to the village communities who assisted the locals with food and provisions, and there were no bans on local culture or religion; even if restrictions were imposed, the consequences were not harsh. The CPK were considered heroes of the revolution as they struggled for the cause of the peasantry and nation against the United States (Hinton, 2005:58). As the Cham communities were to be found across DK, various Cham communities might have experienced the effects of the CPK pre-1975 differently; some communities experienced the repressions and restrictions while others did not. Only when Pol Pot had consolidated power by the end of 1975 that the persecution became more severe and affected all of the Cham people indiscriminately. This could well be one of the simpler factors as to why the Cambodian government and the Extraordinary Chambers in the Courts of Cambodia (ECCC) do not prosecute the pre-1975 Khmer Rouge perpetrators before Pol Pot consolidated his power. As such, the accounts of those who experienced the repressions prior to 1975 were not considered to be part of the genocide as the case for a systematic annihilation of a people based on ethnic or religious profiling was not concrete enough.

Emancipation: Freedom from slavery.

Mortar: An unrifled artillery gun which was designed to launch shells over walls and enemy fortifications. The most famous Civil War mortar is the "Dictator" -- a mortar which was mounted on a railroad car and used during the siege of Petersburg. With its 13 inch bore it was capable of launching two hundred pound shells.

Pontoon Bridge: (pronounced pawn-TOON) A floating bridge which was constructed by anchoring a series of large, flat-bottomed boats across a waterway and then laying wooden planks across them. The planks (the "chess") were anchored by side rails and then covered with a layer of soil to protect it and to dampen sounds. Pontoon bridges were extremely important to the outcome of several battles, including Fredericksburg.

Enfilade: (pronounced en-fuh-leyd) To fire along the length of an enemy's battle line.

Goober Pea: A common Southern term for "peanut".

Ethnic victims

Scholars and historians have varying opinions on whether the persecution and killings under the hands of the Khmer Rouge should be considered genocide. This is because the earlier scholarship which came about right after the fall of the Khmer Rouge regime in 1979 had claimed that the victims could have been killed due to the circumstances they were in. For instance, Michael Vickery opined that the killings were "largely the result of the spontaneous excesses of a vengeful, undisciplined peasant army."

This view was also supported by Alexander Hinton, who related an account by a former Khmer Rouge cadre who claimed that the killings were acts of retribution for the injustices of the Lon Nol soldiers when they killed people who were known to be former Viet Minh agents before the rise of Pol Pot and Khmer Rouge to power. Vickery�"erroneously, as maintained by the more recent scholarship of Ben Kiernan�"argued that the number of Cham victims during the Khmer Rouge regime to be around 20,000 which would rule out the crime of genocide against Pol Pot and the Khmer Rouge. The killings were a centralized and bureaucratic effort by the Khmer Rouge regime, as recently documented by the Documentation Center of Cambodia (DC-Cam) through the discovery of Khmer Rouge internal security documents which instructed the killings across Cambodia. However there were also instances of "indiscipline and spontaneity in the mass killings." On top of that, Etcherson has also maintained that with the systematic mass killings based on political affiliation, ethnicity, religion, and citizenship resulting in the loss of a third of the Cambodian population, the Khmer Rouge is effectively guilty of committing genocide.

Recruits: The term used to describe new soldiers.

Shoddy: Term for cheap, poorly made cloth which was used early in the war to make Federal uniforms. The cloth fell apart very quickly. Eventually "shoddy" became a term for inferior, poorly made items.

Napoleonic Tactics: The tactics used by Napoleon Bonaparte that were studied by military men and cadets at West Point before the Civil War. His tactics were brilliant for the technology of warfare at the time he was fighting. However, by the Civil War, weapons had longer ranges and were more accurate than they had been in Napoleon's day.

Percussion Arm: A musket or rifle-musket that requires a cap to fire. A tiny cap is placed on the gun so that when a trigger is pulled, the hammer strikes the cap. The chemical in the cap (fulminate of mercury) ignites and flame shoots into the chamber that holds the gunpowder. This ignites the powder and the blast shoots the bullet out of the barrel. (Percussion means striking�"a drum is a percussion instrument and a gun that uses a hammer to strike a cap is a percussion arm.)

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.

Tuol Sleng Genocide Museum - History

To accommodate the victims of purges that were important enough for the attention of the Khmer Rouge, a new detention center was planned in the building that was formerly known as Tuol Svay Prey High School, named after a royal ancestor of King Norodom Sihanouk, the five buildings of the complex were converted in March or April 1976 into a prison and an interrogation center. Before, other buildings in town were used already as prison S-21. The Khmer Rouge renamed the complex "Security Prison 21" (S-21) and construction began to adapt the prison for the inmates: the buildings were enclosed in electrified barbed wire, the classrooms converted into tiny prison and torture chambers, and all windows were covered with iron bars and barbed wire to prevent escapes and suicides.

Recruits: The term used to describe new soldiers.

Barrel: The long metal tube on a gun through which a projectile is fired.
