just go to google and type in "civil war in vietnam"...
make sure to put it in quotes
"In April 1975, after decades of civil war in Vietnam, the forces of the totalitarian government of North Vietnam were victorious. The South Vietnamese regime fell, and their supporters, the United States army, withdrew in defeat. Hundreds of thousands of Vietnamese secretly fled in desperation to escape political persecution, torture and reprisals. Often, they escaped by sea in small unseaworthy boats. "
