A U.S. Marine Corps Hawk air defense missile battalion is deployed to Da Nang. President Johnson had ordered this deployment to provide protection for the key U.S. airbase there.

This was the first commitment of American combat troops in South Vietnam and there was considerable reaction around the world to the new stage of U.S. involvement in the war. Predictably, both communist China and the Soviet Union threatened to intervene if the United States continued to apply its military might on behalf of the South Vietnamese. In Moscow, some 2,000 demonstrators, led by Vietnamese and Chinese students and clearly supported by the authorities, attacked the U.S. Embassy. Britain and Australia supported the U.S. action, but France called for negotiations.
