On 18 August, "Theodore E. Chandler" retired from the Korean coast with the rest of the "Helena" group and set course for Japan. The task element reached Sasebo that same day but on the 23rd returned to Korean waters. The next day, "Chandler" and the other destroyers of DesDiv 111 aided "Helena" bombard the railroad cars and warehouses at Tanchon. On 26 August, the task element arrived off Pohang to relieve the unit in supporting the northeastern end of the UN line. The warships remained in that area with "Helena" until 29 August when they returned to Sasebo for an overnight stopover and, the next day, resumed station off Pohang. After three days off the east coast of Korea, the destroyer reentered Sasebo on 2 September. Ten days later, she headed for the western coast of Korea and the amphibious operation at Inchon.
