The Cambodian genocide

The Cambodian genocide was the systematic persecution and killing of Cambodians by the Khmer Rouge under the leadership of Communist Party of Kampuchea general secretary Pol Pot, who radically pushed Cambodia towards an entirely self-sufficient agrarian socialist society. It resulted in the deaths of 1.5 to 2 million people from 1975 to 1979, nearly a quarter of Cambodia's population in 1975 (c. 7.8 million).

Pol Pot and the Khmer Rouge had long been supported by the Chinese Communist Party (CCP) and its chairman, Mao Zedong;[a] it is estimated that at least 90% of the foreign aid which the Khmer Rouge received came from China, including at least US$1 billion in interest-free economic and military aid in 1975 alone. After it seized power in April 1975, the Khmer Rouge wanted to turn the country into an agrarian socialist republic, founded on the policies of ultra-Maoism and influenced by the Cultural Revolution.[b] Pol Pot and other Khmer Rouge officials met with Mao in Beijing in June 1975, receiving approval and advice, while high-ranking CCP officials such as Politburo Standing Committee member Zhang Chunqiao later visited Cambodia to offer help.[c] To fulfill its goals, the Khmer Rouge emptied the cities and forced Cambodians to relocate to labor camps in the countryside, where mass executions, forced labor, physical abuse, malnutrition, and disease were rampant. In 1976, the Khmer Rouge renamed the country Democratic Kampuchea.

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.)

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.

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

Ramrod: Long, cylindrical metal rod used to push the cartridge down the barrel of a musket in preparation for firing.

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