Question

Explanation:

This iconic photograph shows a U.S. helicopter evacuating people from the roof of the U.S. Embassy in Saigon in April 1975, which occurred as North Vietnamese forces captured the city, marking the fall of Saigon and the end of U.S. involvement in the Vietnam War. The event was not a U.S. military success, and the evacuation was a desperate measure as the city fell, not a large-scale rescue of Vietnamese people.

Answer:

The fall of Saigon
