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.

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.

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.

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.

"Graybacks": A slang term for lice, or occasionally an offensive "Yankee" slang term for Confederate soldiers.

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

Tuol Sleng Genocide Museum - "Skull map"

The buildings at Tuol Sleng are preserved, some rooms as they were left when the Khmer Rouge were driven out in 1979. The regime kept extensive records, including thousands of photographs. Several rooms of the museum are now lined, floor to ceiling, with black and white photographs of some of the estimated 20,000 prisoners who passed through the prison.

The site has four main buildings, known as Building A, B, C, and D. Building A holds the large cells in which the bodies of the last victims were discovered. Building B holds galleries of photographs. Building C holds the rooms sub-divided into small cells for prisoners. Building D holds other memorabilia including instruments of torture.

Militia: Troops, like the National Guard, who are only called out to defend the land in an emergency.

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

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

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.

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

Tuol Sleng Genocide Museum - History

Upon arrival at the prison, prisoners were photographed and required to give detailed autobiographies, beginning with their childhood and ending with their arrest. After that, they were forced to strip to their underwear, and their possessions were confiscated. The prisoners were then taken to their cells. Those taken to the smaller cells were shackled to the walls or the concrete floor. Those who were held in the large mass cells were collectively shackled to long pieces of iron bar. The shackles were fixed to alternating bars; the prisoners slept with their heads in opposite directions. They slept on the floor without mats, mosquito nets, or blankets. They were forbidden to talk to each other.

Fieldworks: Temporary fortifications put up by an army in the field.

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.

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

Brevet: (pronounced brehv-it) An honorary promotion in rank, usually for merit. Officers did not usually function at or receive pay for their brevet rank.

Infantry: A branch of the military in which soldiers traveled and fought on foot.

United States - Operation Breakfast

From 1970 to 1973 a massive United States bombing campaign against the Khmer Rouge devastated rural Cambodia. An earlier U.S. bombing campaign of Cambodia actually started on 18 March 1969 with Operation Breakfast, but U.S. bombing in Cambodia started years earlier than that.

The number of Cambodian civilian and Khmer Rouge deaths caused by U.S. bombing is disputed and difficult to disentangle from the broader Cambodian Civil War. Estimates range from 30,000 to 500,000. Sliwinski estimates that approximately 17% of total civil war deaths can be attributed to U.S. bombing, noting that this is far behind the leading causes of death, as the U.S. bombing was concentrated in underpopulated border areas. Ben Kiernan attributes 50,000 to 150,000 deaths to the U.S. bombing.

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

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.

Foraging: A term used for "living off the land," as well as plundering committed by soldiers.

Courier: (pronounced KUHR-ee-er) A soldier who served the officers of his regiment by carrying mail or messages.

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

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.

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.

Dropsy: (pronounced drop-see) Nineteenth-century term for the condition known today as edema. Fluid builds up in the tissues and causes limbs to swell up horribly.

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.

Rout: A crushing defeat where, often, the losers run from the field.

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

Ethnic victims

David Chandler has argued that, although ethnic minorities fell victim to the Khmer Rouge regime, they were not targeted specifically because of their ethnic backgrounds, but rather because they were mostly enemies of the regime. Chandler also rejects the use of the terms "chauvinism" and "genocide" just to avoid drawing possible parallels to Hitler. This indicates that Chandler does not believe in the argument of charging the Khmer Rouge regime with the crime of genocide. Similarly, Michael Vickery holds a similar position to Chandler's, and refuses to acknowledge the atrocities of the Khmer Rouge regime as genocide; Vickery regarded the Khmer Rouge a "chauvinist" regime, due to its anti-Vietnam and anti-religion policies. Stephen Heder also conceded that the Khmer Rouge were not guilty of genocide, stating that the atrocities of the regime were not motivated by race.

Ben Kiernan makes the argument that it was indeed a genocide and disagrees with these three scholars, by bringing forth examples from the history of the Cham people in Cambodia, as did an international tribunal finding Nuon Chea and Khieu Samphan guilty of 92 and 87 counts of said crime respectively.

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

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.

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.

Insult: A sudden, open, unconcealed attack upon a fortified position with the intent of capturing it before its defenders could mount an effective defense.

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.

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.

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.

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

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.

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

Brevet: (pronounced brehv-it) An honorary promotion in rank, usually for merit. Officers did not usually function at or receive pay for their brevet rank.

United States - Sihanouk

Pol Pot biographer David P. Chandler writes that the bombing "had the effect the Americans wanted�"it broke the Communist encirclement of Phnom Penh", but also accelerated the collapse of rural society and increased social polarization. Craig Etcheson agrees that U.S. intervention increased recruitment for the Khmer Rouge but disputes that it was a primary cause of the Khmer Rouge victory. According to William Shawcross, the United States bombing and ground incursion plunged Cambodia into the chaos that Sihanouk had worked for years to avoid.

Arsenal: A place where weapons and other military supplies are stored.

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

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.

Total War: A new way of conducting war appeared during the Civil War. Instead of focusing only on military targets, armies conducting total war destroyed homes and crops to demoralize and undermine the civilian base of the enemy's war effort. (Sherman in Georgia or Sheridan in the Shenandoah Valley, for example.)

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".

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".

Reinforcements: Troops sent to strengthen a fighting force by adding an additional number of fresh soldiers.

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

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

Recruits: The term used to describe new soldiers.

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

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.

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.

Rout: A crushing defeat where, often, the losers run from the field.

Chevaux-de-Frise: (pronounced sheh-VOH-de-freez) A defensive obstacle constructed by using a long horizontal beam pierced with diagonal rows of sharpened spikes. When several cheval-de-frise (singular, pronounced she-VAL-de-freez) were bolted together they created an effective barrier for roads and fortifications.

Muster: To formally enroll in the army or to call roll.

Courier: (pronounced KUHR-ee-er) A soldier who served the officers of his regiment by carrying mail or messages.

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.

"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.

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

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).

Rifle-Musket: The common weapon of the Civil War infantryman, it was a firearm fired from the shoulder. It differed from a regular musket by the grooves (called rifling) cut into the inside of the barrel. When the exploding powder thrusts the bullet forward, the grooves in the barrel make it spin, just like a football spirals through the air. Rifle-muskets were more accurate and had a longer range than smoothbore weapons.

Chevaux-de-Frise: (pronounced sheh-VOH-de-freez) A defensive obstacle constructed by using a long horizontal beam pierced with diagonal rows of sharpened spikes. When several cheval-de-frise (singular, pronounced she-VAL-de-freez) were bolted together they created an effective barrier for roads and fortifications.

Chinese

The state of the Chinese Cambodians during the Khmer Rouge regime was alleged to be "the worst disaster ever to befall any ethnic Chinese community in Southeast Asia." Cambodians of Chinese descent were massacred by the Khmer Rouge under the justification that they "used to exploit the Cambodian people". The Chinese were stereotyped as traders and moneylenders associated with capitalism, while historically the group had attracted resentment due to their lighter skin color and cultural differences. Hundreds of Cham, Chinese and Khmer families were rounded up in 1978 and told that they were to be resettled, but were actually executed.

At the beginning of the Khmer Rouge regime in 1975, there were 425,000 ethnic Chinese in Cambodia. By the end of 1979 there were just 200,000 stuck at Thai refugee camps or Cambodia. 170,000 Chinese fled Cambodia to Vietnam while others were repatriated. The Chinese were predominantly city-dwellers, making them vulnerable to the Khmer Rouge's revolutionary ruralism and evacuation of city residents to farms. The government of the People's Republic of China did not protest the killings of ethnic Chinese in Cambodia, despite being aware of the atrocities and simultaneously condemning Vietnam's treatment of ethnic Chinese.

Flying Battery: A system where several horse-drawn cannons would ride along the battle front, stop and set up the guns, fire, limber up, and ride to another position. This practice gave the impression that many guns were in use when only a few were actually being used.

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.

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.

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.

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

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.

Recruits: The term used to describe new soldiers.

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.

Defensive: Resisting or protecting against attack from someone.

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

Bivouac: (pronounced BIH-voo-ack) Temporary soldier encampment in which soldiers were provided no shelter other than what could be assembled quickly, such as branches; sleeping in the open.

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."

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.

Canister: A projectile, shot from a cannon, filled with about 35 iron balls the size of marbles that scattered like the pellets of a shotgun.

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.

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

Chevaux-de-Frise: (pronounced sheh-VOH-de-freez) A defensive obstacle constructed by using a long horizontal beam pierced with diagonal rows of sharpened spikes. When several cheval-de-frise (singular, pronounced she-VAL-de-freez) were bolted together they created an effective barrier for roads and fortifications.

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".

Ambush: To lie in wait for an unexpected attack.

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.

Republican Party: A political party created in the 1850s to prevent the spread of slavery to the territories. Eventually Republicans came to oppose the entire existence of slavery. Abraham Lincoln was the first Republican president. Very few Southerners were Republicans.

Ratify: To formally approve or sanction.

Cash Crop: A crop such as tobacco or cotton which was grown to be sold for cash --not grown for food like corn or wheat.

Chinese

The state of the Chinese Cambodians during the Khmer Rouge regime was alleged to be "the worst disaster ever to befall any ethnic Chinese community in Southeast Asia." Cambodians of Chinese descent were massacred by the Khmer Rouge under the justification that they "used to exploit the Cambodian people". The Chinese were stereotyped as traders and moneylenders associated with capitalism, while historically the group had attracted resentment due to their lighter skin color and cultural differences. Hundreds of Cham, Chinese and Khmer families were rounded up in 1978 and told that they were to be resettled, but were actually executed.

At the beginning of the Khmer Rouge regime in 1975, there were 425,000 ethnic Chinese in Cambodia. By the end of 1979 there were just 200,000 stuck at Thai refugee camps or Cambodia. 170,000 Chinese fled Cambodia to Vietnam while others were repatriated. The Chinese were predominantly city-dwellers, making them vulnerable to the Khmer Rouge's revolutionary ruralism and evacuation of city residents to farms. The government of the People's Republic of China did not protest the killings of ethnic Chinese in Cambodia, despite being aware of the atrocities and simultaneously condemning Vietnam's treatment of ethnic Chinese.

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.

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

Flying Battery: A system where several horse-drawn cannons would ride along the battle front, stop and set up the guns, fire, limber up, and ride to another position. This practice gave the impression that many guns were in use when only a few were actually being used.

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

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.

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.

Reconstruction: A term used to describe the time in American history directly after the Civil War during which the South was "reconstructed" by the North after its loss in the war.

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.

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.

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

Interior Lines: A military strategy which holds that the fastest, most efficient maneuvers, transportation and communication are conducted within an enclosed geographic area as opposed to outside the geographic area.

Ideology

A doctoral dissertation written by Kenneth M. Quinn about the "origins of the radical Pol Pot regime" is "widely acknowledged as the first person to report on the genocidal policies of Pol Pot and the Khmer Rouge." While he was employed as a Foreign Service Officer for the U.S. State Department in Southeast Asia, Quinn was stationed at the South Vietnamese border for nine months between 1973�"1974. While there, Quinn "interviewed countless Cambodian refugees who had escaped the brutal clutches of the Khmer Rouge." Based upon the compiled interviews and the atrocities he witnessed firsthand, Quinn wrote "a 40-page report about it, which was submitted throughout the U.S. government." In the report, he wrote that the Khmer Rouge had "much in common with those of totalitarian regimes in Nazi Germany and the Soviet Union." Quinn has written of the Khmer Rouge that "[w]hat emerges as the explanation for the terror and violence that swept Cambodia during the 1970s is that a small group of alienated intellectuals, enraged by their perception of a totally corrupt society and imbued with a Maoist plan to create a pure socialist order in the shortest possible time, recruited extremely young, poor, and envious cadres, instructed them in harsh and brutal methods learned from Stalinist mentors, and used them to destroy physically the cultural underpinnings of the Khmer civilization and to impose a new society through purges, executions, and violence."

Ben Kiernan has compared the Cambodian genocide to the Armenian genocide which was perpetrated by the Ottoman Empire during World War I and the Holocaust which was perpetrated by Nazi Germany during World War II. While each genocide was unique, they shared certain common features, and racism was a major part of the ideology of all three regimes. All three regimes targeted religious minorities and they also tried to use force in order to expand their rule into what they believed were their historic heartlands (the Khmer Empire, Turkestan, and Lebensraum, respectively), and all three regimes "idealized their ethnic peasantry as the true 'national' class, the ethnic soil from which the new state grew."

Canister: A projectile, shot from a cannon, filled with about 35 iron balls the size of marbles that scattered like the pellets of a shotgun.

Coup de Main: (pronounced koo-duh-mahn) A French term used to describe a quick, vigorous attack that surprises the enemy.

Corps: (pronounced kohr or korz) A very large group of soldiers led by (Union) a major general or (Confederate) a lieutenant general and designated by Roman numerals (such as XI Corps). Confederate corps were often called by the name of their commanding general (as in Jackson's Corps). 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.

Muster: To formally enroll in the army or to call roll.

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 - 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.

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

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.

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.

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.

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.

United States - Sihanouk

Pol Pot biographer David P. Chandler writes that the bombing "had the effect the Americans wanted�"it broke the Communist encirclement of Phnom Penh", but also accelerated the collapse of rural society and increased social polarization. Craig Etcheson agrees that U.S. intervention increased recruitment for the Khmer Rouge but disputes that it was a primary cause of the Khmer Rouge victory. According to William Shawcross, the United States bombing and ground incursion plunged Cambodia into the chaos that Sihanouk had worked for years to avoid.

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.

Popular Sovereignty: (pronounced sov-rin-tee) This doctrine was prominent during the debate over slavery in the territories. Popular sovereignty said that the people of each territory should be able to decide for themselves if slavery should be allowed in their territory when it became a state.

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.

Juggernaut: (pronounced juhg-er-nawt) An overwhelming, advancing force that crushes or seems to crush everything in its path.

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.

Other support

As a result of Chinese and Western opposition to the Vietnamese invasion of 1978 and 1979, the Khmer Rouge continued to hold Cambodia's United Nations (UN) seat until 1982, after which the seat was filled by a Khmer Rouge-dominated coalition which was known as the Coalition Government of Democratic Kampuchea (CGDK). Motivated by its opposition to Vietnam, China trained Khmer Rouge soldiers on its soil from 1979 to at least 1986, "stationed military advisers with Khmer Rouge troops as late as 1990," and "supplied at least $1 billion in military aid" during the 1980s.

After the 1991 Paris Peace Accords, Thailand continued to allow the Khmer Rouge "to trade and move across the Thai border to sustain their activities ... although international criticism, particularly from the United States and Australia ... caused it to disavow passing any direct military support." There are also allegations that the United States directly or indirectly supported the Khmer Rouge because it wanted to weaken Vietnam's influence in Southeast Asia. Owing to support from China, Thailand, other South East Asian countries, the U.S., and some Western countries, the CGDK held Cambodia's UN seat until 1993, long after the Cold War had ended.

Ratify: To formally approve or sanction.

Fieldworks: Temporary fortifications put up by an army in the field.

Brevet: (pronounced brehv-it) An honorary promotion in rank, usually for merit. Officers did not usually function at or receive pay for their brevet rank.

(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.

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.

Tuol Sleng Genocide Museum - Torture and extermination

In their confessions, the prisoners were asked to describe their personal background. If they were party members, they had to say when they joined the revolution and describe their work assignments in DK. Then the prisoners would relate their supposed treasonous activities in chronological order. The third section of the confession text described prisoners' thwarted conspiracies and supposed treasonous conversations. At the end, the confessions would list a string of traitors who were the prisoners' friends, colleagues, or acquaintances. Some lists contained over a hundred names. People whose names were in the confession list were often called in for interrogation.

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.

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.

Scurvy: (pronounced SKUR-vee) A disease caused by lack of ascorbic acid (found in fresh fruits and vegetables). Its symptoms include spongy gums, loose teeth, and bleeding into the skin and mucous membranes.

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.

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.

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.

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.

Breach: A large gap or "hole" in a fortification's walls or embankments caused by artillery or mines, exposing the inside of the fortification to assault.

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.

Breech-loading: Rifle-muskets that could be loaded at the breech (in the middle between the barrel and the stock) instead of from the end (by shoving gunpowder and a ball down the barrel) were called breech-loading guns.

Corps: (pronounced kohr or korz) A very large group of soldiers led by (Union) a major general or (Confederate) a lieutenant general and designated by Roman numerals (such as XI Corps). Confederate corps were often called by the name of their commanding general (as in Jackson's Corps). 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.

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.

Total War: A new way of conducting war appeared during the Civil War. Instead of focusing only on military targets, armies conducting total war destroyed homes and crops to demoralize and undermine the civilian base of the enemy's war effort. (Sherman in Georgia or Sheridan in the Shenandoah Valley, for example.)

Interior Lines: A military strategy which holds that the fastest, most efficient maneuvers, transportation and communication are conducted within an enclosed geographic area as opposed to outside the geographic area.

Confederacy: Also called the South or the Confederate States of America, the Confederacy incorporated the states that seceded from the United States of America to form their own nation. Confederate states were: Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia.

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

"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.

Tuol Sleng Genocide Museum - Non-Cambodian prisoners

One of the last foreign prisoners to die was twenty-nine-year-old American Michael S. Deeds, who was captured with his friend Christopher E. DeLance on November 24, 1978, while sailing from Singapore to Hawaii. His confession was signed a week before the Vietnamese army invaded Cambodia and ousted the Khmer Rouge. In 1989, Deeds' brother, Karl Deeds, traveled to Cambodia in attempts to find his brother's remains, but was unsuccessful. On September 3, 2012, DeLance's photograph was identified among the caches of inmate portraits.

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.

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

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.

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.

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.

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.

"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.

Shell: A hollow projectile, shot from a cannon; a shell was filled with powder and lit by a fuse when it was fired. Shells exploded when their fuse burned down to the level of the powder. Depending on the length of the fuse, artillerymen could decide when they wanted the shell to burst.

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

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

Tuol Sleng Genocide Museum - History

Militia: Troops, like the National Guard, who are only called out to defend the land in an emergency.

"Graybacks": A slang term for lice, or occasionally an offensive "Yankee" slang term for Confederate soldiers.

Rebel: Loyal to the Confederate States. Also Southern or Confederate.

Bedroll: Blanket or other bedding rolled up and carried over the shoulder by a soldier. Sometimes soldiers would include personal belongings in their bedroll.

Deng era

See also: Sino-Vietnamese War
Soon after Deng became the Paramount Leader of China, the Vietnamese invaded Cambodia and ended the genocide by defeating the Khmer Rouge in January 1979. The People's Republic of Kampuchea was then established. In order to counter the power of Soviet Union and Vietnam in Southeast Asia, China officially condemned the Vietnamese invasion and continued its material support to Khmer Rouge. In early 1979, China launched an invasion of Vietnam to retaliate against Vietnam's invasion of Cambodia.

Deng was convinced by a conversation with Singapore's prime minister Lee Kuan Yew to limit the scale and duration of the war. Following the one-month war, Singapore attempted to serve as a mediator between Vietnam and China on the Cambodian issue.

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.

Corps: (pronounced kohr or korz) A very large group of soldiers led by (Union) a major general or (Confederate) a lieutenant general and designated by Roman numerals (such as XI Corps). Confederate corps were often called by the name of their commanding general (as in Jackson's Corps). 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.

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.

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

(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.

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.

Defeat in Detail: Defeating a military force unit by unit. This occurred when units were unable to support one another, often because of distance.

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.

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.

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.

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

Defensive: Resisting or protecting against attack from someone.

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.

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.

Skirmish: A minor fight.

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.

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.

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.

Infantry: A branch of the military in which soldiers traveled and fought on foot.
