A force of 10,000 South Vietnamese troops, supported by 200 U.S. advisers, aircraft and logistical elements, attack into the thing that was defined as the “Parrot’s Beak,” the location of Cambodia that projects into South Vietnam above the Mekong Delta. The South Vietnamese reached town of Takeo in a 20-mile thrust. This action was percentage of the ongoing operation ordered by President Richard Nixon in April. U.S. and South Vietnamese forces launched a limited “incursion” into Cambodia that integrated 13 major ground operations to clear North Vietnamese sanctuaries 20 miles within the Cambodian border in each the “Parrot’s Beak” and the densely vegetated “Fishhook” location (throughout the border from South Vietnam, 70 miles from Saigon). Some 50,000 South Vietnamese soldiers and 30,000 U.S. troops have now been involved, creating it the greatest operation of the war considering that Operation Junction City in 1967.
In the United States, news of the incursion tripped a wave of antiwar demonstrations, including just one at Kent State University that led to the killing of four students by Army National Guard troops. Another protest at Jackson State in Mississippi triggered the shooting of two students when police opened fire on a women’s dormitory. The incursion also angered several in Congress who felt that Nixon was illegally widening the scope of the war this led to a number of congressional resolutions and legislative initiatives that will severely limit the executive energy of the president.
