IX Corps, the 65th Regimental Combat Team assembled near Kyongan-ni, southeast of Seoul and directly below the Pukhan River corridor; and the 7th Regimental Combat Team assembled in Seoul for missions in the I Corps' sector. The six ROK divisions on the eastern front were to stay forward of the No-Name Line but were not to make further attempt to occupy the Missouri Line In the X Corps sector, the ROK 5th and 7th Divisions, whose forces had all but reached the Soyang River southwest of Inje, were to fortify their present positions. ROK III Corps and ROK I Corps were to set their four divisions in fortified defenses between the lower bank of the Soyang south of Inje and the town of Kangson-ni, north of Yang-yang on the coast, after conducting spoiling attacks on 12 May in the two principal communications centers ahead of them, Inje and Yongdae-ri, the latter located on Route 24 northeast of Inje. The reconnaissance company of the ROK 9th Division already had entered Inje without a fight during the afternoon of the 11th and dispersed an enemy force about beyond the town before retiring on the 12th, but other forces of the two ROK corps were prevented by distance and moderate resistance from reaching the objectives of their attacks in the one day allotted for them. Light contact along the remainder of the front revealed little about PVA/KPA dispositions, but the composite of reports from air observers, agents, civilians, and prisoners made clear by 13 May that major PVA forces had begun to shift eastward from the west and west-central sectors. Steady rain and fog all but eliminated further air observation on 14 and 15 May; poor visibility also hampered ground patrols; and a IX Corps' reconnaissance-in-force by the 187th Airborne Regimental Combat Team up the valley northeast of Kapyong toward what was believed to be a large concentration of enemy forces had to be cancelled shortly after it started on the 15th because of the rain and poor road conditions. As much as could be determined by 16 May was that the eastward shift probably extended to the Chuncheon area. A few reports tracing the shift indicated that some PVA units would move beyond Chuncheon. According to a PVA medical officer captured northeast of Seoul on 10 May, the 12th Army and two other armies were scheduled to leave the west central area
