She continued this role as the UN troops recaptured Seoul days later. "Boxer" continued this support as UN troops advanced north and into North Korea, but departed for the United States on 11 November for refit and overhaul. US military commanders believed the war in Korea was over, and had ordered a number of other carriers out of the area and were subsequently under-prepared at the beginning of the Chosin Reservoir Campaign when the Chinese People's Liberation Army entered the war against the UN. Battlefield commanders requested "Boxer" return to Korea as soon as possible, but she did not immediately return as commanders feared it might reduce the Navy's ability to respond if another conflict or emergency broke out elsewhere."Boxer"s propulsion problems required extensive repair, so she returned to San Diego to conduct them. Upon arrival, she offloaded Air Group 2, which then embarked for Korea again aboard "Valley Forge". After a repair and refit in California, "Boxer" was prepared for a second tour in Korea. She embarked Carrier Air Group 101. The group was composed of Navy Reserve squadrons from Dallas, Texas, Glenview, Illinois, Memphis, Tennessee and Olathe, Kansas, and most of its pilots were reservists who had been called to active duty. She rejoined Task Force 77, and began operations in Korea on 29 March 1951, and her squadrons were the first Naval Reserve pilots to launch strikes in Korea. Most of these missions were airstrikes against Chinese ground forces along the 38th parallel, and this duty lasted until 24 October 1951. During this time, the carrier operated around "Point Oboe", an area off the coast of Wonsan. They would withdraw another east when they needed replenishment or refueling. A large destroyer screen protected the carriers, though MiG-15 attacks against them did not occur.
