Other support

As a result of Chinese and Western opposition to the Vietnamese invasion of 1978 and 1979, the Khmer Rouge continued to hold Cambodia's United Nations (UN) seat until 1982, after which the seat was filled by a Khmer Rouge-dominated coalition which was known as the Coalition Government of Democratic Kampuchea (CGDK). Motivated by its opposition to Vietnam, China trained Khmer Rouge soldiers on its soil from 1979 to at least 1986, "stationed military advisers with Khmer Rouge troops as late as 1990," and "supplied at least $1 billion in military aid" during the 1980s.

After the 1991 Paris Peace Accords, Thailand continued to allow the Khmer Rouge "to trade and move across the Thai border to sustain their activities ... although international criticism, particularly from the United States and Australia ... caused it to disavow passing any direct military support." There are also allegations that the United States directly or indirectly supported the Khmer Rouge because it wanted to weaken Vietnam's influence in Southeast Asia. Owing to support from China, Thailand, other South East Asian countries, the U.S., and some Western countries, the CGDK held Cambodia's UN seat until 1993, long after the Cold War had ended.

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

Rout: A crushing defeat where, often, the losers run from the field.

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.

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.)

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.
