Australian women protest conscription during Vietnam War [Save Our Sons (SOS)], 1965-1972
The “Gulf of Tonkin Incident” in early August 1964 marked the beginning of dramatic escalation of the United States’ involvement in the civil war in Vietnam. As a close ally, Australia made a commitment to support the United States’ intervention in Southeast Asia. To support the war effort, Prime Minister Robert Menzies’s Liberal government introduced conscription for national military service on November 10, 1964. A few months later on April 29, Menzies announced that Australian troops, including National Service conscripts, would be sent to Vietnam to assist in the American war effort.
