Tuol Sleng Genocide Museum

The Tuol Sleng Genocide Museum or simply Tuol Sleng; lit. "Hill of the Poisonous Trees" or "Strychnine Hill") is a museum chronicling the Cambodian genocide. Located in Phnom Penh, the site is a former secondary school which was used as Security Prison 21 (S-21; Khmer: ម�"�'�'ីរស-២១) by the Khmer Rouge regime from 1975 until its fall in 1979. From 1976 to 1979, an estimated 20,000 people were imprisoned at Tuol Sleng and it was one of between 150 and 196 torture and execution centers established by the Khmer Rouge. On 26 July 2010, the Extraordinary Chambers in the Courts of Cambodia convicted the prison's chief, Kang Kek Iew, for crimes against humanity and grave breaches of the 1949 Geneva Conventions. He died on 2 September 2020 while serving a life sentence.

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

Navy: A branch of the military using ships to conduct warfare. During the Civil War, "blue water" ships cruised the oceans and "brown water" boats floated up and down the rivers.

Monitor: Originally, the U.S.S. Monitor, the first ironclad warship in the United States Navy, commanded by Admiral John L. Worden. The vessel had a large, round gun turret on top of a flat raft-like bottom, which caused some spectators to describe it as a "cheesebox on a raft." The first engagement between ironclads occurred on March 8-9, 1862, at the Battle of Hampton Roads, VA, when the U.S.S. Monitor fought the C.S.S. Virginia (formerly the U.S.S. Merrimack). Eventually a "monitor" became the official term for an entire class of warships modeled after the original U.S.S. Monitor.

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

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.

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".

Brigade: A large group of soldiers usually led by a brigadier general. A brigade was made of four to six regiments. 1 company = 50 to 100 men, 10 companies = 1 regiment, about 4 regiments = 1 brigade, 2 to 5 brigades = 1 division, 2 or more divisions = 1 corps, 1 or more corps = 1 army.

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.

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.

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.

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

Tuol Sleng Genocide Museum - History

The prison had very strict regulations, and severe beatings were inflicted upon any prisoner who disobeyed. Almost every action had to be approved by one of the prison's guards. The prisoners were sometimes forced to eat human feces and drink human urine. The unhygienic living conditions in the prison caused skin diseases, lice, rashes, ringworm and other ailments. The prison's medical staff were untrained and offered treatment only to sustain prisoners' lives after they had been injured during interrogation. When prisoners were taken from one place to another for interrogation, they were blindfolded. Guards and prisoners were not allowed to converse. Moreover, within the prison, people who were in different groups were not allowed to have contact with one another.

Salient: (pronounced SAY-lee-uhnt) A part of a defensive line of works or a fortification that juts out from the main line towards the enemy. Salients can be very vulnerable to because they may be attacked from multiple sides.

Armory: A place where weapons and other military supplies are manufactured.

Army: The largest organizational group of soldiers, made up of one or more corps. There were 16 Union armies (named after rivers, such as the Army of the Potomac) and 23 Confederate armies (named after states or regions, such as the Army of Northern Virginia). 1 company = 50 to 100 men, 10 companies = 1 regiment, about 4 regiments = 1 brigade, 2 to 5 brigades = 1 division, 2 or more divisions = 1 corps, 1 or more corps = 1 army.

Revenue Cutter:This term applies to fast ships that were used to patrol the seas and Great Lakes to prevent smuggling and impose importation and custom fees. Revenue cutters would go on to become the United States Coast Guard.

Vedette(or vidette): A mounted sentry stationed in advance of a picket line.

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.

"Powder Monkey": A sailor (sometimes a child) who carried explosives from the ship's magazine to the ship's guns.

Sectionalism: Promoting the interests of a section or region (such as the North or the South) instead of the entire country.

Navy: A branch of the military using ships to conduct warfare. During the Civil War, "blue water" ships cruised the oceans and "brown water" boats floated up and down the rivers.

Armory: A place where weapons and other military supplies are manufactured.

Democratic Party: The major political party in America most sympathetic to states rights and willing to tolerate the spread of slavery to the territories. Democrats opposed a strong Federal government. Most Southern men were Democrats before the War.

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.

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

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

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.)

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.

Carbine: A breech-loading, single-shot, rifle-barreled gun primarily used by cavalry troops. A carbine's barrel is several inches shorter than a regular rifle-musket.

Blockade: The effort by the North to keep ships from entering or leaving Southern ports.

Volunteer: Someone who does something because they want to, not because they need to. Most Civil War soldiers, especially in the beginning of the War, were volunteers. Men joined the armies on both sides because they wanted to fight for their cause.

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.

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

Casualty: A soldier who was wounded, killed, or missing in action.

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.

Vedette(or vidette): A mounted sentry stationed in advance of a picket line.

Rampart: A large earthen mound used to shield the inside of a fortified position from artillery fire and infantry assault. Occasionally ramparts might be constructed of other materials, such as sandbags.

Barbette: Raised platform or mound allowing an artillery piece to be fired over a fortification's walls without exposing the gun crew to enemy fire.

Minie Bullet (or minié bullet): (pronounced min-ee or min-ee-ay) The standard infantry bullet of the Civil War. The bullet was designed for muzzle-loading rifle-muskets. It was invented by two Frenchmen, Henri-Gustave Delvigne and Claude-Étienne Minié (pronounced "min-ee-ay"). It was small enough to load quickly, and had a special feature that let it take advantage of a rifled-barrel. When the rifle-musket was fired, expanding gas from the gunpowder blast was caught in the hollow base of the bullet forcing it against the rifled grooves inside the barrel.

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.

Surrender: To admit defeat and give up in the face of overwhelming odds. Most defeated generals were able to negotiate surrender terms. These might include items like parole instead of prison for the soldiers or letting officers keep their sidearms.

Sap Roller: A very large, bullet resistant gabion which was used to protect soldiers from enemy fire as they constructed trenches.

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.

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.

Brogan: A leather shoe, similar to an ankle-high boot, issued to soldiers during the Civil War. Brogans were also popular amongst civilians during the time period.

Twenty-six-year-old John D. Dewhirst, a British tourist, was one of the youngest foreigners to die in the prison. He was sailing with his New Zealand companion, Kerry Hamill, and their Canadian friend Stuart Glass when their boat drifted into Cambodian territory and was intercepted by Khmer patrol boats on August 13, 1978. Glass was killed during the arrest, while Dewhirst and Hamill were captured, blindfolded, and taken to shore. Both were executed after having been tortured for several months at Tuol Sleng. Witnesses reported that a foreigner was burned alive; initially, it was suggested that this might have been John Dewhirst, but a survivor would later identify Kerry Hamill as the victim of this particular act of brutality. Robert Hamill, his brother and a champion Atlantic rower, would years later make a documentary, Brother Number One, about his brother's incarceration.

"Powder Monkey": A sailor (sometimes a child) who carried explosives from the ship's magazine to the ship's guns.

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

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.

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.

Abolitionist: Someone who wishes to abolish or get rid of slavery.

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.

"Powder Monkey": A sailor (sometimes a child) who carried explosives from the ship's magazine to the ship's guns.

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

Theater: A theater of war is a region or area where fighting takes place.

Rebel Yell: A high-pitched cry that Confederate soldiers would shout when attacking. First heard at First Manassas (First Bull Run) Union troops found the eerie noise unnerving.

Defilade: (pronounced DEH-fih-lade) To arrange walls, embankments and other features of a fortification or field work so that the enemy cannot make an accurate shot inside.

Tuol Sleng Genocide Museum - Prison Staff

The defense unit was the largest unit in S-21. The guards in this unit were mostly teenagers. Many guards found the unit's strict rules hard to obey. Guards were not allowed to talk to prisoners, to learn their names, or to beat them. They were also forbidden to observe or eavesdrop on interrogations, and they were expected to obey 30 regulations, which barred them from such things as taking naps, sitting down or leaning against a wall while on duty. They had to walk, guard, and examine everything carefully. Guards who made serious mistakes were arrested, interrogated, jailed and put to death. Most of the people employed at S-21 were terrified of making mistakes and feared being tortured and killed.

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.

Colors: A flag identifying a regiment or army. The "Color Bearer" was the soldier who carried the flag in battle, which was considered a great honor.

Muzzle-loading: Muzzle-loading muskets or rifle muskets had to be loaded from the end by putting the gunpowder and the bullet or ball down the barrel.

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".

Redan: (pronounced ri-dan) A fortification with two parapets or low walls whose faces unite to form a salient angle towards the enemy. That is, they form a point that juts out past the rest of the defensive line of works.

Classicide

The Khmer Rouge regime frequently arrested and often executed anyone who it suspected of having connections with the former Cambodian government or foreign governments, as well as professionals, intellectuals, the Buddhist monkhood, and ethnic minorities. Even those people who were stereotypically thought of as having intellectual qualities, such as wearing glasses or speaking multiple languages, were executed out of fear that they would rebel against the Khmer Rouge. As a result, Pol Pot has been described as "a genocidal tyrant" by journalists and historians such as William Branigin. The British sociologist Martin Shaw described the Cambodian genocide as "the purest genocide of the Cold War era". The attempt to purify Cambodian society along racial, social and political lines led to purges of Cambodia's previous military and political leadership, along with business leaders, journalists, students, doctors, and lawyers.

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.

Caisson: (pronounced kay-suhn) �" A two-wheeled cart that carried two ammunition chests, tools, and a spare wheel for artillery pieces. The caisson could be attached to a limber, which would allow both to be pulled by a team of horses.

Ambush: To lie in wait for an unexpected attack.

Rebel Yell: A high-pitched cry that Confederate soldiers would shout when attacking. First heard at First Manassas (First Bull Run) Union troops found the eerie noise unnerving.

Litter: A stretcher which was carried by two people and used to transport wounded soldiers.

Salient: (pronounced SAY-lee-uhnt) A part of a defensive line of works or a fortification that juts out from the main line towards the enemy. Salients can be very vulnerable to because they may be attacked from multiple sides.

Emancipation: Freedom from slavery.

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

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

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.

Mao era

Since the 1950s, Pol Pot had made frequent visits to the People's Republic of China, where he received political and military training�"especially on the theory of the dictatorship of the proletariat�"from the personnel of the CCP. From November 1965 to February 1966, high-ranking CCP officials such as Chen Boda and Zhang Chunqiao trained him on topics such as the communist revolution in China, class conflicts, Communist International, etc. Pol Pot also met with other officials, including Deng Xiaoping and Peng Zhen. He was particularly impressed by Kang Sheng's lecture on how to conduct a political purge.

Defensive: Resisting or protecting against attack from someone.

Massacre: The cruel killing of a number of helpless or unresisting people.

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.

Ironclad: A ship protected by iron armor.

Vedette(or vidette): A mounted sentry stationed in advance of a picket line.

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.

Carbine: A breech-loading, single-shot, rifle-barreled gun primarily used by cavalry troops. A carbine's barrel is several inches shorter than a regular rifle-musket.

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

Whig Party: A political party generally against slavery and its expansion into the territories. The Whig party had basically been swallowed up by the Democrat and Republican parties by the time of the Civil War.

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.

Theater: A theater of war is a region or area where fighting takes place.

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.

Shebangs: (pronounced sheh-bang) The crude shelters Civil War prisoners of war built to protect themselves from the sun and rain.

Caisson: (pronounced kay-suhn) �" A two-wheeled cart that carried two ammunition chests, tools, and a spare wheel for artillery pieces. The caisson could be attached to a limber, which would allow both to be pulled by a team of horses.

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.

Offensive: Actively attacking someone.

Charge: To rush towards the enemy.

Tuol Sleng Genocide Museum - Concentration camp rules

When prisoners were first brought to Tuol Sleng, they were made aware of ten rules that they were to follow during their incarceration. What follows is what is posted today at the Tuol Sleng Museum; the imperfect grammar is a result of faulty translation from the original Khmer:

You must answer accordingly to my question. Don't turn them away.
Don't try to hide the facts by making pretexts this and that, you are strictly prohibited to contest me.
Don't be a fool for you are a chap who dare to thwart the revolution.
You must immediately answer my questions without wasting time to reflect.
Don't tell me either about your immoralities or the essence of the revolution.
While getting lashes or electrification you must not cry at all.
Do nothing, sit still and wait for my orders. If there is no order, keep quiet. When I ask you to do something, you must do it right away without protesting.
Don't make pretext about Kampuchea Krom in order to hide your secret or traitor.
If you don't follow all the above rules, you shall get many lashes of electric wire.
If you disobey any point of my regulations you shall get either ten lashes or five shocks of electric discharge.
During testimony at the Khmer Rouge Tribunal on April 27, 2009, Duch claimed the 10 security regulations were a fabrication of the Vietnamese officials that first set up the Tuol Sleng Genocide Museum.

Whig Party: A political party generally against slavery and its expansion into the territories. The Whig party had basically been swallowed up by the Democrat and Republican parties by the time of the Civil War.

Monitor: Originally, the U.S.S. Monitor, the first ironclad warship in the United States Navy, commanded by Admiral John L. Worden. The vessel had a large, round gun turret on top of a flat raft-like bottom, which caused some spectators to describe it as a "cheesebox on a raft." The first engagement between ironclads occurred on March 8-9, 1862, at the Battle of Hampton Roads, VA, when the U.S.S. Monitor fought the C.S.S. Virginia (formerly the U.S.S. Merrimack). Eventually a "monitor" became the official term for an entire class of warships modeled after the original U.S.S. Monitor.

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

"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.

Limber: A two-wheeled cart that carried one ammunition chest for an artillery piece. The artillery piece could be attached to the limber, which would allow both to be pulled by a team of horses. Also verb: The practice of attaching a piece of artillery to the limber that holds its ammunition.

The Cambodian genocide

The massacres ended when the Vietnamese military invaded in 1978 and toppled the Khmer Rouge regime. By January 1979, 1.5 to 2 million people had died due to the Khmer Rouge's policies, including 200,000�"300,000 Chinese Cambodians, 90,000�"500,000 Cambodian Cham (who are mostly Muslim), and 20,000 Vietnamese Cambodians. 20,000 people passed through the Security Prison 21, one of the 196 prisons the Khmer Rouge operated, and only seven adults survived. The prisoners were taken to the Killing Fields, where they were executed (often with pickaxes, to save bullets) and buried in mass graves. Abduction and indoctrination of children was widespread, and many were persuaded or forced to commit atrocities. As of 2009, the Documentation Center of Cambodia has mapped 23,745 mass graves containing approximately 1.3 million suspected victims of execution. Direct execution is believed to account for up to 60% of the genocide's death toll, with other victims succumbing to starvation, exhaustion, or disease.

Demonstration: A military movement which is used to draw the enemy's attention, distracting the enemy so that an attack can be made in another location.

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.

West Point: The United States Military Academy at West Point, New York was the military school for more than 1,000 officers in both the Union and Confederate armies�"including Robert E. Lee and Ulysses S. Grant.

Vedette(or vidette): A mounted sentry stationed in advance of a picket line.

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.

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.

Earthwork: A field fortification (such as a trench or a mound) made of earth. Earthworks were used to protect troops during battles or sieges, to protect artillery batteries, and to slow an advancing enemy.

Federal: Loyal to the government of the United States. Also known as Union, Yankee, or Northern.

Housewife: Small sewing kit soldiers used to repair their garments.

"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.

Rebel Yell: A high-pitched cry that Confederate soldiers would shout when attacking. First heard at First Manassas (First Bull Run) Union troops found the eerie noise unnerving.

Cham Muslims

In 1975, upon the victory of the CPK over the Khmer Republic forces, two brothers of Cham descent who had joined the Khmer Rouge as soldiers returned home to Region 21 within the Kampong Cham Province, where the largest Cham Muslim community could be found. The brothers then told their father of the adventures they had experienced being part of the revolution which included killing Khmers and consuming pork, in the hopes of convincing their father to join the communist cause. The father who had remained silent, was clearly not intrigued by the accounts related by his sons. Instead, he grabbed a cleaver, killed his sons, and told his fellow villagers that he had killed the enemy. When the villagers pointed out that he had indeed murdered his own sons, he recounted the stories he was told by his sons earlier, citing the Khmer Rouge's hatred for Islam and the Cham people. This prompted a unanimous agreement amongst the villagers to kill all Khmer Rouge soldiers within the area on that night. The next morning, more Khmer Rouge forces descended the area with heavy weapons and surrounded the village, killing every single villager in it.

Similarly, in June or July 1975, the CPK authorities in Region 21 of the Eastern Zone tried to confiscate all copies of the Qur'an from the people, while at the same time impose a mandatory short haircut for Cham women. The authorities were met with mass demonstration staged by the local Cham community who were shot at by the regime soldiers. The Cham retaliated forcefully with swords and blades killing a few soldiers, only to be met with military reinforcement from the regime which annihilated the villagers and their properties. In another account by Cham refugees in Malaysia, thirteen leading figures within the Cham Muslim community were killed by the regime in June 1975. The reasons behind the killings was supposedly because some of them were "leading prayers instead of attending a CPK meeting", while the others were purportedly "petitioning for the permission on marriage ceremonies."

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.

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".

Salient: (pronounced SAY-lee-uhnt) A part of a defensive line of works or a fortification that juts out from the main line towards the enemy. Salients can be very vulnerable to because they may be attacked from multiple sides.

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".

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

Tuol Sleng Genocide Museum

Other rooms contain only a rusting iron bedframe, beneath a black and white photograph showing the room as it was found by the Vietnamese. In each photograph, the mutilated body of a prisoner is chained to the bed, killed by his fleeing captors only hours before the prison was captured. Other rooms preserve leg-irons and instruments of torture. They are accompanied by paintings by former inmate Vann Nath showing people being tortured, which were added by the post-Khmer Rouge regime installed by the Vietnamese in 1979.

Reserve(s): Part(s) of the army which were withheld from fighting during a particular battle but ready and available to fight if necessary.

Flank: Used as a noun, a "flank" is the end (or side) of a military position, also called a "wing". An unprotected flank is "in the air", while a protected flank is a "refused flank". Used as a verb, "to flank" is to move around and gain the side of an enemy position, avoiding a frontal assault.

Minie Bullet (or minié bullet): (pronounced min-ee or min-ee-ay) The standard infantry bullet of the Civil War. The bullet was designed for muzzle-loading rifle-muskets. It was invented by two Frenchmen, Henri-Gustave Delvigne and Claude-Étienne Minié (pronounced "min-ee-ay"). It was small enough to load quickly, and had a special feature that let it take advantage of a rifled-barrel. When the rifle-musket was fired, expanding gas from the gunpowder blast was caught in the hollow base of the bullet forcing it against the rifled grooves inside the barrel.

Cambodian Civil War

In 1968, the Khmer Rouge officially launched a nation-wide insurgency across Cambodia. Even though the government of North Vietnam had not been informed of the Khmer Rouge's decision, its forces provided shelter and weapons to the Khmer Rouge after the insurgency began. North Vietnamese support for the Khmer Rouge's insurgency made it impossible for the Cambodian military to effectively counter it. For the next two years, the insurgency grew because Norodom Sihanouk did very little to stop it. As the insurgency grew in strength, the party openly declared itself to be the Communist Party of Kampuchea.

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.

Tuol Sleng Genocide Museum - Discovery

In 1979, H�" Văn Tây, a Vietnamese combat photographer, was the first journalist to document Tuol Sleng to the world. H�" and his colleagues followed the stench of rotting corpses to the gates of Tuol Sleng. The photos of H�" documenting what he saw when he entered the site are exhibited in Tuol Sleng today.

The Khmer Rouge required that the prison staff make a detailed dossier for each prisoner. Included in the documentation was a photograph. Since the original negatives and photographs were separated from the dossiers in the 1979�"1980 period, most of the photographs remain anonymous to this day.

Abolitionist: Someone who wishes to abolish or get rid of slavery.

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.

Tuol Sleng Genocide Museum - Prison Staff

Some of the staff who worked in Tuol Sleng also ended up as prisoners. They confessed to being lazy in preparing documents, to having damaged machines and various equipment, and to having beaten prisoners to death without permission when assisting with interrogations.

Brogan: A leather shoe, similar to an ankle-high boot, issued to soldiers during the Civil War. Brogans were also popular amongst civilians during the time period.

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

Cap: Essential to firing a percussion rifle-musket, a cap is a tiny brass shell that holds fulminate of mercury. The cap is placed on the gun so that when a trigger is pulled, the hammer falls on the cap. The chemical in the cap 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.

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.

The documentation unit was responsible for transcribing tape recorded confessions, typing the handwritten notes from prisoners' confessions, preparing summaries of confessions, and maintaining files. In the photography sub-unit, workers took mug shots of prisoners when they arrived, pictures of prisoners who had died while in detention, and pictures of important prisoners after they were executed. Thousands of photographs have survived, but thousands are still missing.

(Attack) In Detail: To destroy the enemy piece by piece �" by attacking smaller segments one at a time �" instead of attacking the entire force all at once.

Rampart: A large earthen mound used to shield the inside of a fortified position from artillery fire and infantry assault. Occasionally ramparts might be constructed of other materials, such as sandbags.

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.

Hardtack: Hardtack is a term used to describe the hard crackers often issued to soldiers of both sides during the Civil War. These crackers consisted of nothing more than flour, water, and salt. They were simple and inexpensive to make in very large quantities. However, these crackers became almost rock solid once they went stale.

Napoleon Gun: Another name for the Model 1857 gun howitzer. This lighter, more maneuverable field artillery piece fired 12 pound projectiles and was very popular with both Federal and Confederate armies.

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.

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.

Rifled: A gun barrel is rifled when it has grooves (called rifling) cut into the inside of the barrel for longer range and more accurate firing.

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.

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

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.

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.

Carbine: A breech-loading, single-shot, rifle-barreled gun primarily used by cavalry troops. A carbine's barrel is several inches shorter than a regular rifle-musket.

Commutation: Stipulation adopted by both the Union and Confederate governments which allowed certain draftees to pay a fee in order to avoid military service. Because the fee was higher than the average worker's annual salary, this provision angered less-wealthy citizens on both sides of the war.

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.

Tuol Sleng Genocide Museum

The Tuol Sleng Genocide Museum or simply Tuol Sleng; lit. "Hill of the Poisonous Trees" or "Strychnine Hill") is a museum chronicling the Cambodian genocide. Located in Phnom Penh, the site is a former secondary school which was used as Security Prison 21 (S-21; Khmer: ម�"�'�'ីរស-២១) by the Khmer Rouge regime from 1975 until its fall in 1979. From 1976 to 1979, an estimated 20,000 people were imprisoned at Tuol Sleng and it was one of between 150 and 196 torture and execution centers established by the Khmer Rouge. On 26 July 2010, the Extraordinary Chambers in the Courts of Cambodia convicted the prison's chief, Kang Kek Iew, for crimes against humanity and grave breaches of the 1949 Geneva Conventions. He died on 2 September 2020 while serving a life sentence.

Tuol Sleng Genocide Museum - Survivors

Out of an estimated 20,000 people imprisoned at Tuol Sleng, there were only twelve known survivors: seven adults and five children. One child died shortly after the liberation. As of mid-September 2011, only three of the adults and four children are thought to be still alive: Chum Mey, Bou Meng, and Chim Meth. All three said they were kept alive because they had skills their captors judged to be useful. Bou Meng, whose wife was killed in the prison, is an artist. Chum Mey was kept alive because of his skills in repairing machinery. Chim Meth was held in S-21 for 2 weeks and transferred to the nearby Prey Sar prison. She may have been spared because she was from Stoeung district in Kampong Thom where Comrade Duch was born. She intentionally distinguished herself by emphasising her provincial accent during her interrogations. Vann Nath, who was spared because of his ability to paint, died on September 5, 2011. Norng Chan Phal, one of the surviving children published his story in 2018.
