For almost a month, "Chandler" cruised the waters of the Yellow Sea. The destroyer helped soften the positions until the landings on 15 September and, after that, covered the amphibious forces and conducted bombardments which aided the troops ashore in advancing. Early in October, she completed her mission in the Yellow Sea and returned to Sasebo on 5 October. During the next two months, she operated along Korea's eastern coast, interdicting communist supply lines with gunfire. Early in December, she made a brief stop at Sasebo before beginning a month of duty on station off Hungnam. During the evacuation of UN troops from that North Korean port, "Theodore E. Chandler" once again had the opportunity to aid land forces—hard-pressed since the intervention of communist China in late November—to hold a precarious perimeter during an evacuation operation. "Theodore E. Chandler" remained in the general neighborhood for an additional two weeks.
