Withdrawal Of U.S. Troops From Vietnam Resumed
 
   

March 4--The withdrawal of U.S. troops from Vietnam resumed and the naval minesweeping force returned to its position off Haiphong. Minesweeping operations continued in and around Haiphong and the harbor was reopened after being closed for ten months because of the U.S. naval mining which began in May 1972. In addition, the carrier America was ordered to depart the Far East for the U.S. This was the initial move in reducing the number of carriers serving in South East Asia from six to three by mid-June 1973.
