The Cambodian genocide

The genocide triggered a second outflow of refugees, many of whom escaped to neighboring Thailand and, to a lesser extent, Vietnam. The Vietnamese invasion of Cambodia ended the genocide by defeating the Khmer Rouge in January 1979. In 2001, the Cambodian government established the Khmer Rouge Tribunal to try the members of the Khmer Rouge leadership responsible for the Cambodian genocide. Trials began in 2009, and in 2014, Nuon Chea and Khieu Samphan were convicted and received life sentences for crimes against humanity committed during the genocide.

Bombproof: A field fortification which was made to absorb the shock of artillery strikes. It was constructed of heavy timbers and its roof was covered with soil.

Vedette(or vidette): A mounted sentry stationed in advance of a picket line.

Rampart: A large earthen mound used to shield the inside of a fortified position from artillery fire and infantry assault. Occasionally ramparts might be constructed of other materials, such as sandbags.

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.

Minie Bullet (or minié bullet): (pronounced min-ee or min-ee-ay) The standard infantry bullet of the Civil War. The bullet was designed for muzzle-loading rifle-muskets. It was invented by two Frenchmen, Henri-Gustave Delvigne and Claude-Étienne Minié (pronounced "min-ee-ay"). It was small enough to load quickly, and had a special feature that let it take advantage of a rifled-barrel. When the rifle-musket was fired, expanding gas from the gunpowder blast was caught in the hollow base of the bullet forcing it against the rifled grooves inside the barrel.
