At Yŏngsan, despite the absence of air support, the Marines had continued their advance westward on the afternoon of the 3rd. By nightfall the originally scheduled line of departure had been gained or surpassed and the enemy, disorganized by the shock of this unexpected engagement, was retiring. But the front was a long one, re-curving into a deep salient north of the road, and the night was made miserable by cold, driving rain.
At sea, despite the improved results in close support, the task force was again trying to shake itself loose. In preparation for the proposed landing at Inch'ŏn Admiral Struble had established and ComNavFE had promulgated a new series of carrier aircraft operating areas, M through Q, along the west coast of Korea, and had called for operations in Areas P and Q, north of 38°, on the 4th, and in 0 and P, between 37° and 39° on the 5th. Pursuant to these instructions Admiral Ewen’s dispatch reporting his launch on the afternoon of the 3rd had stated that unless otherwise directed he intended to operate north of the parallel next day.
