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.

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

Salt Pork: Salt pork is a pork product similar to bacon that is made by curing pork bellies in salt. This curing process allowed the pork to last a very long time without the need for refrigeration. As a result, salt pork became a common food issued to soldiers by both the North and the South.

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.

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

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.

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.

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

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.

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

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

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.

Cham Muslims

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

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

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.

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

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.

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.

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.

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.

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.

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.)

U.S. Christian Commission: An organization established in 1861 for the relief of Union soldiers; the Christian Commission provided food, Bibles, and free writing materials to the soldiers to encourage them in good moral behavior.

States Rights: This doctrine held the powers of the individual states as greater than the powers of the Federal government. States rights meant that the Federal government held its power only through the consent of the states and that any powers not specifically given to the Federal government remained in control of the states.

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.

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.

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

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

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.

Union: Also called the North or the United States, the Union was the portion of the country that remained loyal to the Federal government during the Civil War. Union states were: Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota, Missouri, 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.

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.

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.

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.

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.

Ironclad: A ship protected by iron armor.

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

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.

Offensive: Actively attacking someone.

"Peculiar Institution": Another term for slavery in 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.

Smoothbore: A gun is smoothbore if the inside of the barrel is completely smooth. Smoothbore guns were used before rifled guns were developed. Although smoothbores were not as accurate and had a shorter range than rifled arms, there were still plenty of them in use during the Civil War.

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

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.

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

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.

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.

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.

Ratify: To formally approve or sanction.

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.

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.

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

Copperhead: Term for a Northerner who opposed the war effort.

States Rights: This doctrine held the powers of the individual states as greater than the powers of the Federal government. States rights meant that the Federal government held its power only through the consent of the states and that any powers not specifically given to the Federal government remained in control of the states.

Tuol Sleng Genocide Museum - History

The day began in the prison at 4:30 a.m. when prisoners were ordered to strip for inspection. The guards checked to see if the shackles were loose or if the prisoners had hidden objects they could use to commit suicide. Over the years, several prisoners managed to kill themselves, so the guards were very careful in checking the shackles and cells. The prisoners received four small spoonfuls of rice porridge and a watery soup of leaves twice a day. Drinking water without asking the guards for permission resulted in serious beatings. The inmates were hosed down every four days.

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.

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.

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.

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

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.

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.

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

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.

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.

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

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.
