On this day, 58 years ago, October 21, 1967 (September 18, 1967 in the lunar calendar), the United States broke out in a peaceful march to Washington. In the 1960s, the U.S. government continued to intensify its aggression against Vietnam, but it was strongly opposed by its own people. On October 21, 1967, thousands of demonstrators from all over the United States flocked to Washington, D.C., and gathered in front of the Lincoln Monument. They held high placards such as "Withdraw the army immediately,""Abolish the conscription system" and "We will not go to Vietnam (to fight)." In the afternoon, a conference attended by more than 100,000 demonstrators was held to strongly condemn the war of aggression against Vietnam carried out by the Johnson administration and the conscription system. After the meeting, the demonstrators sang anti-war songs and chanted slogans against the war of aggression and marched towards the Pentagon, where the U.S. Department of Defense is located. Demonstrators surrounded the Ministry of Defense building and stormed it. They clashed with military police armed with various weapons, and some of the crowd also rushed into the Pentagon and fought with the military police in the corridor. About 700 people were arrested and 1,400 injured.
