Four miles south of the Demilitarized Zone (DMZ), about 500 U.S. troops of the 1st Brigade, 5th Mechanized Division turn over Fire Base Charlie 2 to Saigon troops, completing the transfer of defense responsibilities for the border area. On the previous day, nearby Fire Base Alpha 4 had been turned over to the South Vietnamese. This was part of President Richard Nixon’s Vietnamization policy, which had been announced at a June 1969 conference at Midway Island. Under this program, the United States initiated a comprehensive effort to increase the combat capabilities of the South Vietnamese armed forces. As the South Vietnamese became more capable, responsibility for the fighting was gradually transferred from U.S. forces. Concurrent with this effort, there was a gradual withdrawal of U.S. forces.
