IX Corps commander Major General Bryant Moore chose the 1st Marine Division to make the IX Corps drive along Route 29. The division initially was to seize high ground just south of Hoengsong from which it could control that road center. To the west, the ROK 6th Infantry Division, British 27th Infantry Brigade and the US 1st Cavalry Division were to clear the mountains between the Marines and the Han. In the X Corps' zone, the US 7th Infantry Division and ROK 3rd Division were to open the advance to the Arizona Line; they were to be joined later by the 2nd Infantry Division after it shifted east from Wonju. The damaged ROK 5th and 8th Infantry Divisions were to move off the line, the 5th to help protect the Corps' supply route, the more severely reduced 8th to go south to Daegu, where it was to be rebuilt under ROK control.^[3]:?3

About 10:30 on 24 February, the helicopter carrying Major General Moore crashed into the Han River and Moore subsequently died of a heart attack. He was temporarily replaced by 1st Marine Division commander Major General Oliver P. Smith.^{[3]:?308–9?}

可見，在2月24日之前，陸戰一師即已經與韓軍第6師，美軍騎一師等部隊並肩作戰了，24日以後，陸戰一師師長代理了第9軍軍長之職。
