Communist launch new offensive - May 25, 1968 - HISTORY.com

The communists launch their third major assault of the year on Saigon. The heaviest fighting occurred during the first three days of June, and again centered on Cholon, the Chinese section of Saigon, where U.S. and South Vietnamese forces used helicopters, fighter-bombers, and tanks to dislodge deeply entrenched Viet Cong infiltrators. A captured enemy directive, which the U.S. command made public on May 28, indicated that the Viet Cong saw the offensive as a means of influencing the Paris peace talks in their favor.
