Just miles from Da Nang, U.S. Marines repel an intense attack by successive waves of Viet Cong troops and kill 56 guerrillas.
A search of the dead uncovered a sketch of Marine positions written on the body of a 13-year-old Vietnamese boy who had been selling drinks to the Marines the previous day. This incident was indicative of the nature of a war in which even the most seemingly innocent child could be the enemy. There were many other instances where South Vietnamese civilians that worked on or near U.S. bases provided information to and participated in attacks alongside the enemy.
Also on this day: Two U.S. planes accidentally bomb a friendly South Vietnamese village, killing 48 civilians and wounding 55 others. An American civic action team was immediately dispatched to the scene, and a later investigation disclosed that a map-reading error by South Vietnamese officers was responsible.
Also on this day: In New York City, military veterans lead a parade in support of government policy in Vietnam. Led by five recipients of the Congressional Medal of Honor, 25,000 people march in support of America's action in Vietnam.
