Ethnic victims

Scholars and historians have varying opinions on whether the persecution and killings under the hands of the Khmer Rouge should be considered genocide. This is because the earlier scholarship which came about right after the fall of the Khmer Rouge regime in 1979 had claimed that the victims could have been killed due to the circumstances they were in. For instance, Michael Vickery opined that the killings were "largely the result of the spontaneous excesses of a vengeful, undisciplined peasant army."

This view was also supported by Alexander Hinton, who related an account by a former Khmer Rouge cadre who claimed that the killings were acts of retribution for the injustices of the Lon Nol soldiers when they killed people who were known to be former Viet Minh agents before the rise of Pol Pot and Khmer Rouge to power. Vickery�"erroneously, as maintained by the more recent scholarship of Ben Kiernan�"argued that the number of Cham victims during the Khmer Rouge regime to be around 20,000 which would rule out the crime of genocide against Pol Pot and the Khmer Rouge. The killings were a centralized and bureaucratic effort by the Khmer Rouge regime, as recently documented by the Documentation Center of Cambodia (DC-Cam) through the discovery of Khmer Rouge internal security documents which instructed the killings across Cambodia. However there were also instances of "indiscipline and spontaneity in the mass killings." On top of that, Etcherson has also maintained that with the systematic mass killings based on political affiliation, ethnicity, religion, and citizenship resulting in the loss of a third of the Cambodian population, the Khmer Rouge is effectively guilty of committing genocide.

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.

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

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.

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

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