Two women joined a line of people to take their toddlers away from Hanoi in December, 1972.
The largest evacuation in the resistance history of the capital was basically completed before the United States launched the Operation Linebacker campaign, which lasted 12 days and nights from December 18 to 29 in 1972.
About 85% of the population of four Hanoi urban districts, or around 500,000 people, were evacuated to Hanoi’s surrounding areas, including the former Ha Tay Province, which became a part of Hanoi in 2008.
Air defense positions and bomb shelters were built and set up right in the middle of the streets.
The city had around 400,000 single-person bomb shelters and hundreds of thousands of tunnels for groups of people to escape from the bombings during this time.

Together with the main force and the local army, the Hanoi militia and self-defense force established 192 defensive positions across the city.
More than 40,000 people were equipped with rifles, machine guns and mortars.

The commune was one of the first locations to be hit by B-52 bombs on the opening night of the U.S. campaign on December 18, 1972. The attack was the heaviest bombardment launched by the U.S. Air Force since the end of World War II.

A day earlier, many people received the information that the United States would stop bombing on Christmas Eve so they returned home and could not escape the bombings in time. As a result, 287 people died that night and more than 2,000 houses were destroyed.
