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".

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

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

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

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".

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.
