Nineteen years, five months, four weeks and a day – that's how long the Vietnam War lasted.
It came to an end 40 years ago this week, in the final days of April 1975, as U.S. personnel fled a city quickly falling to Communist forces from the north of the country. By April 30, the Vietnamese that remained in Saigon – now Ho Chi Minh city – faced dire conditions.
"Virtually no provisions had been made for their evacuation," said Marilyn Young, professor of History at New York University and author of "The Vietnam Wars: 1945-1990."
In the end, thousands of South Vietnamese were evacuated, but there were no clear guidelines to determine who would leave and who was left behind.
"The top people in the government made arrangements and they got out with their money and their goods," said Young. "Lower down it was much more of a hit or miss…and if you missed, you really missed."
Of those who remained, high-ranking Saigon government officials or those known for aiding Americans were likely to suffer longer periods of time in political prisons, also known as re-education camps.
Many of those who fled the violence eventually settled in Southern California, where another journey to rebuild lives and establish bonds in a new land began.
