The KPA continued to push the U.S. forces back into a perimeter around the port city of Pusan. Kapaun continued to make the rounds to encourage and pray with the troops of the 8th Regiment. His main complaint was lack of sleep for several weeks at a time. Finally, in mid-September and after the landing at Inchon, Kapaun and the rest of the United Nations Command forces broke out of the perimeter and pursued the KPA northward. On October 9, the division crossed the 38th parallel into North Korea, capturing the capital of Pyongyang and advancing to within of the Chinese border.
