Vietnamese

The Khmer Rouge initially ordered the expulsion of ethnic Vietnamese from Cambodia but then conducted large scale massacres of large numbers of Vietnamese civilians who were being deported out of Cambodia. The regime then prevented the remaining 20,000 ethnic Vietnamese from fleeing, and much of this group was also executed. The Khmer Rouge also used the media to support their goals of genocide. Radio Phnom Penh called on Cambodians to "exterminate the 50 million Vietnamese."

Additionally, the Khmer Rouge conducted many cross-border raids into Vietnam where they slaughtered an estimated 30,000 Vietnamese civilians. Most notably, during the Ba Chúc massacre in April 1978, the Khmer Rouge military crossed the border and entered the village, slaughtering 3,157 Vietnamese civilians. This caused an urgent response from the Vietnamese government, precipitating the Cambodian�"Vietnamese War in which the Khmer Rouge was ultimately defeated.[117

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.)

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

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.

Traverse: A mound of earth used to protect gun positions from explosion or to defilade the inside of a field work or fortification.

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.

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.

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.

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.

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

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

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.

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.

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.

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.

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.

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".

Traverse: A mound of earth used to protect gun positions from explosion or to defilade the inside of a field work or fortification.

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.

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.

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.

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

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.

Bummer: A term used to describe marauding or foraging soldiers. Although armies on both sides often had rules against foraging or stealing from private residences, some soldiers often found ways to do so.
