Two of the objectives mentioned in these orders, Chongjin and the northern border of Korea, were more than 300 road miles north of Wonsan. With the exception of the main coastal route, most of the roads in the 1st Marine Division zone were mere mountain trails, unfit for tanks or heavy vehicles. OpnO 18-50 was modified the next day to provide for attaching the 1st Battalion, KMC Regiment, to the 5th Marines, and the 5th KMC Battalion to the 1st Marines. The security of the Munchon and Yonghung areas (13 and 32 miles north of Wonsan respectively) was assigned for the time being to the 5th Marines, reinforced by Company A of the 1st Tank Battalion. On the 27th General Smith moved from the _Mount McKinley_ at 1000 to the new Division CP, a mile north of Wonsan. An old Russian barracks, it was too small and badly in need of repairs. The building occupied by the 1st Marine Air Wing was in even worse shape, but carpenters were soon busy at boarding up windows and doors blown out by bombs.[123] [123] Smith, _Chronicle_, 66; MajGen E.
