In the first major offensive ordered for U.S. forces in Vietnam, 3,000 troops of the 173rd Airborne Brigade—in conjunction with 800 Australian soldiers and a Vietnamese airborne unit—assault a jungle area known as Viet Cong Zone D, 20 miles northeast of Saigon.
The operation was called off after three days when it failed to make any major contract with the enemy. One American was killed and nine Americans and four Australians were wounded. The State Department assured the American public that the operation was in accord with Johnson administration policy on the role of U.S. troops.
