Tuol Sleng Genocide Museum - Prison Staff

The prison had a staff of 1,720 people throughout the whole period. Of those, approximately 300 were office staff, internal workforce and interrogators. The other 1,400 were general workers, including people who grew food for the prison. Several of these workers were children taken from the prisoner families. The chief of the prison was Khang Khek Ieu (also known as Comrade Duch), a former mathematics teacher who worked closely with Khmer Rouge leader Pol Pot. Other leading figures of S-21 were Kim Vat aka Ho (deputy chief of S-21), Peng (chief of guards), Mam Nai aka Chan (chief of the Interrogation Unit), and Tang Sin Hean aka Pon (interrogator). Pon was the person who interrogated important people such as Keo Meas, Nay Sarann, Ho Nim, Tiv Ol, and Phok Chhay.

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

Breastworks: Barriers which were about breast-high and protected soldiers from enemy fire.

Bayonet: (pronounced bay-uh-net) A metal blade, like a long knife or short sword, that could be attached to the end of a musket or rifle-musket and used as a spear or pike in hand-to-hand combat.

Casemate: (pronounced kays-mayt) A sturdily-built, arched masonry chamber enclosed by a fortification's ramparts or walls. Casemates were often used to protect gun positions, powder magazines, storerooms or living quarters.

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.

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.

Indian Territory: The area that is now Oklahoma (except for the panhandle.)

North: Also called the Union or the United States the North was the part of the country that remained loyal to the Federal government during the Civil War. Northern states were: Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, and Wisconsin. West Virginia became a Northern state in 1863 and California and Oregon were also officially Northern but they had little direct involvement in the War.

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).

Sortie: A type of counter-attack used to disrupt the enemy's attack or siege of a fortification, causing the enemy to divert some of its resources away from the initial attack or siege.

Yankee: A Northerner; someone loyal to the Federal government of the United States. Also, Union, Federal, or Northern.

Cham Muslims

Ten Cham villages were taken over by the CPK in 1972�"1973, where new Cham leaders were instated and led the villagers to work in the fields away from their hometowns. A witness interviewed by Kiernan asserts that they were well-treated by the CPK then, and allowed to return to their homes in 1974. Moreover, the Cham were classified as "depositee base people", making them further vulnerable to persecution. Despite that, the Cham in many areas do live side by side with the locals, speaking the Khmer language, and even inter-marrying with the majority Khmers as well as the minority Chinese and Vietnamese. The diverse ethnic and cultural practices of Cambodians began to deteriorate with the rise of the CPK in 1972, when the Cham were prohibited from practising their faith and culture: Cham women were required to keep their hair short like the Khmers; Cham men were not allowed to put on the sarong; farmers were made to put on rudimentary dark or black clothing; religious activities like the mandatory daily prayers were curbed. Vickery notes that the Cambodian Cham were discriminated against by the Khmer before the beginning of the war "in some localities", partly because the Cham were stereotyped as being practitioners of black magic. In other localities, the Cham were well-assimilated within the host communities, speaking the Khmer language and marrying Khmers, Vietnamese, and the Chinese.

Between 1972 and 1974, the enforcement of such restrictions was further amplified as the Khmer Rouge found the Cham to be a threat to its communist agenda due to their unique language, culture, belief, and independent communal system. Not only that, the Cham were renamed "Islamic Khmers" to disassociate them with their ancestral heritage and ethnicity and assimilate them into the larger Khmer-dominated Democratic Kampuchea. The Khmer Rouge believed that the Cham would jeopardize the communist efforts of establishing close-knit communities where everyone could be easily monitored. As such, the regime had decided to disperse the Cham by deporting them from their respective localities to work as peasants across Cambodia, hence contributing directly to the new DK economy. This move was undertaken to ensure that the Cham will not congregate to form its own community again, which undermines the regime's plan of establishing central economic cooperatives. Slowly, those who defied these restrictions were arrested by the regime. Hence in October 1973, Cham Muslims in the Eastern Zone of DK demonstrated their displeasure towards the CPK restrictions by beating the drums�"traditionally used to inform locals of the time for daily prayers�"at local mosques. This act of communal defiance prompted the blanket arrest of many Cham Muslim leaders and religious teachers.

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.

Zouave: (pronounced zoo-ahv or zwahv) A zouave regiment was characterized by its soldiers' bright, colorful uniforms which usually included baggy trousers, a vest, and a fez in different combinations of red, white, and blue. American zouave units were found in both Union and Confederate armies. They were modeled after French African troops who were known for their bravery and marksmanship

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

Feint: (pronounced feynt) To pretend to attack in one direction while the real attack is directed somewhere else.

Cavalry: A branch of the military mounted on horseback. Cavalry units in the Civil War could move quickly from place to place or go on scouting expeditions on horseback, but usually fought on foot. Their main job was to gather information about enemy movements. Until the spring of 1863, the Confederate cavalry force was far superior to its Federal counterpart.

Transition period

After Mao's death in September 1976, China went through around two years of transition until Deng Xiaoping became its new paramount leader in December 1978. During the transition period, Pol Pot made an official visit to China in July 1977 and he was welcomed by chairman Hua Guofeng and other high-ranking CCP officials, with the People's Daily calling him the "Comrade from Cambodia" . Pot also toured around the agricultural production model of Dazhai, a product of Mao's era. Chen Yonggui, Vice Premier of China and the leader of Dazhai, visited Cambodia in December 1977, commending the achievement of its movement towards communism.

In 1978, Son Sen, a Khmer Rouge leader and the Minister of National Defense of Democratic Kampuchea, visited China and obtained its approval for military aid. In the same year, high-ranking CCP officials such as Wang Dongxing and Deng Yingchao visited Cambodia to offer support.

Greenbacks: Paper currency which began to circulate in the North after February 1862 with the passage of the Legal Tender Act. The bills were called "greenbacks" because of their color.

Entrenchments: Long cuts (trenches) dug out of the earth with the dirt piled up into a mound in front; used for defense.

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

Casemate: (pronounced kays-mayt) A sturdily-built, arched masonry chamber enclosed by a fortification's ramparts or walls. Casemates were often used to protect gun positions, powder magazines, storerooms or living quarters.

Aide-de-Camp: A soldier who was appointed by an officer to be his confidential assistant. The aide wrote and delivered orders and held a position of responsibility which required him to know troop positions and where officer quarters were located. The aide-de-camp was an officer by virtue of his position and he took orders from his commander only.

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.

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.

Parole: A pledge by a prisoner of war or a defeated soldier not to bear arms. When prisoners were returned to their own side during the War (in exchange for men their side had captured) the parole was no longer in effect and they were allowed to pick up their weapons and fight. When the South lost the War and the Confederate armies gave their parole they promised never to bear weapons against the Union again.

Contrabands: Escaped slaves who fled to the Union lines for protection.

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.

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.

Mao - Pol Pot

In June 1975, Pol Pot and other Khmer Rouge officials met with Mao Zedong in Beijing, where Mao lectured Pol Pot on his "Theory of Continuing Revolution under the Dictatorship of the Proletariat", recommending two articles which were written by Yao Wenyuan and sending Pol Pot over 30 books which were authored by Karl Marx, Friedrich Engels, Vladimir Lenin, and Joseph Stalin as gifts. During this meeting, Mao said to Pol Pot:

We agree with you! Much of your experience is better than ours. China is not qualified to criticize you. We committed errors of the political routes for ten times in fifty years�"some are national, some are local…Thus I say China has no qualification to criticize you but to applaud you. You are basically correct…During the transition from the democratic revolution to adopting a socialist path, there exist two possibilities: one is socialism, the other is capitalism. Our situation now is like this. Fifty years from now, or one hundred years from now, the struggle between two lines will exist. Even ten thousand years from now, the struggle between two lines will still exist. When Communism is realized, the struggle between two lines will still be there. Otherwise, you are not a Marxist. This is unity existing among opposites. If one mentions only one side of the two, this is metaphysics. I believe in what Marx and Lenin have said, the that path [of advance] would be tortuous ... Our state now is, as Lenin said, a capitalist state without capitalists. This state protects capitalist rights, and the wages are not equal. Under the slogan of equality, a system of inequality has been introduced. There will exist a struggle between two lines, the struggle between the advanced and the backward, even when Communism is realized. Today we cannot explain it completely.

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.

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.

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.

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

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

Cambodian Civil War

Sihanouk was deposed in 1970. Premier Lon Nol deposed him with the support of the National Assembly, establishing the pro-United States Khmer Republic. On the Chinese Communist Party (CCP)'s advice, Sihanouk, who was in exile in Beijing, formed an alliance with the Khmer Rouge, and became the nominal head of a Khmer Rouge�"dominated government-in-exile (known by its French acronym, GRUNK) backed by China. Although thoroughly aware of the weakness of Lon Nol's forces and loath to commit American military force to the new conflict in any form other than air power, the Nixon administration announced its support for the new Khmer Republic.

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

"Bonnie Blue Flag": Extremely popular Confederate song named after the first flag of the Confederacy, which had one white star on a blue background. The lyrics listed each state in the order in which they seceded from the Union.

Redoubt: (pronounced rih-dowt) An enclosed field work - without redans - which had several sides and was used to protect a garrison from attacks from several directions. While redoubts could be very useful, one key weakness was that each protruding angle was a salient. This meant that the redoubt would be susceptible to enfilading fire. A redoubt could also extend from a permanent fortress.

U.S.C.T.: United States Colored Troops. Federal Army regiments composed of African-American soldiers. The U.S.C.T.'s were established by General Order Number 143, issued May 22, 1863, and included infantry, cavalry and artillery regiments. While the soldiers themselves were African American, officers were white. Until 1864 African American soldiers received less pay than their white counterparts. The most famous USCT regiment is the 54th Massachusetts, composed of free Northern men. The 33rd USCT regiment, however, has the distinction of being the first federally authorized regiment. Composed of freed slaves, it was originally called the 1st South Carolina Volunteer Infantry.

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

Cambodian Civil War

On 29 March 1970, North Vietnam launched an offensive against the Cambodian army. Documents which were uncovered from the Soviet Union's archives reveal that the invasion was launched at the Khmer Rouge's explicit request after negotiations were held with Nuon Chea. A North Vietnamese force quickly overran large parts of eastern Cambodia reaching within 15 miles (24 km) of Phnom Penh before being pushed back. By June, three months after Sihanouk's removal, they had swept government forces from the entire northeastern third of the country. After defeating those forces, the North Vietnamese turned the newly won territories over to the local insurgents. The Khmer Rouge also established "liberated" areas in the south and the southwestern parts of the country, where they operated independently of the North Vietnamese.

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".

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

Offensive: Actively attacking someone.

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

Butternut: Home-made dye used to color "homespun" cloth a yellow-brown color, used when imported gray cloth became scarce. The dye was made from the husks, leaves, bark, branches and/or roots of butternut and walnut trees. "Butternut" was also a slang term for a Confederate soldier.

Standard: A flag or banner carried into battle on a pole.

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.

Haversack: Small canvas bag, about one foot square, used to carry a soldier's food. Typically, these bags were painted with black tar to make them waterproof.

Picket: Soldiers posted on guard ahead of a main force. Pickets included about 40 or 50 men each. Several pickets would form a rough line in front of the main army's camp. In case of enemy attack, the pickets usually would have time to warn the rest of the force.

"Lost Cause": Cultural movement in which Southern states attempted to cope - mentally and emotionally - with devastating defeat and Northern military occupation after the Civil War. The movement idealized life in the antebellum South, loudly protested against Reconstruction policies, and exalted Confederate figures such as "Stonewall" Jackson and Robert E. Lee.

Siege lines: Lines of works and fortifications that are built by both armies during a siege. The defenders build earthworks to strengthen their position inside a fort or city against assault while the besieging army constructs fortifications to protect siege guns and soldiers from sharpshooters inside the city.

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

Tuol Sleng Genocide Museum - History

From 1976 to 1979, an estimated 20,000 people were imprisoned at Tuol Sleng (the real number is unknown). At any one time, the prison held between 1,000 and 1,500 prisoners. They were repeatedly tortured and coerced into naming family members and close associates, who were in turn arrested, tortured and killed. In the early months of S-21's existence, most of the victims were from the previous Lon Nol regime and included soldiers, government officials, as well as academics, doctors, teachers, students, factory workers, monks, engineers, etc. Later, the party leadership's paranoia turned on its own ranks and purges throughout the country saw thousands of party activists and their families brought to Tuol Sleng and murdered. Those arrested included some of the highest ranking politicians such as Khoy Thoun, Vorn Vet and Hu Nim. Although the official reason for their arrest was "espionage", these men may have been viewed by Khmer Rouge leader Pol Pot as potential leaders of a coup against him. Prisoners' families were sometimes brought en masse to be interrogated and later executed at the Choeung Ek extermination center.

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.

Haversack: Small canvas bag, about one foot square, used to carry a soldier's food. Typically, these bags were painted with black tar to make them waterproof.

Border States: The states of Maryland, Delaware, Kentucky, and Missouri. Although these states did not officially join the Confederacy, many of their citizens supported the South.

Quartermaster: The officer who was responsible for supplying clothing, supplies and food for the troops.

Stockade: A line of tall stout posts securely set either as a defense, to keep the enemy out, or as a pen to keep prisoners in.
