TERM

Refugee

A person who is forced to leave their country due to conflict, persecution, or natural disaster and has crossed an international border in order to find safety in another country.

When Saigon fell in 1975, the rest of South Vietnam was also evacuating as quickly as possible. Approximately 100 miles away in Cần Thơ, Consul General Francis Terry McNamara saved hundreds of Vietnamese refugees by devising and leading a risky evacuation.
