On the night of the 20th, Partridge and Colonel McAlister, the Division G-4, interviewed a captured NKPA engineer major at Kimpo Airfield. The prisoner informed them that the bombed highway bridge between Yongdungpo and Seoul had been damaged beyond repair with the means at hand. This agreed with the conclusions of the Marine officers on the basis of aerial observation. Prospects for a span over the Han seemed dim as Partridge was leaving McAlister’s quarters. That very evening, however, Lieutenant Colonel Rowny, chief of the X Corps engineers, telephoned to announce that materials for a floating bridge unit had been accumulated by the Army in Japan and would be flown to Korea shortly. Up to this time, with rafts the only solution, the Marine engineers had supplied all the materials. But Rowny announced that Corps would assume the responsibility after the arrival of enough materials for a floating bridge unit.[308] [308] _Ibid._ Military operations could not wait a week or ten days for the new span, and the Marine ferry plus amtracs and DUKWs[309] had to nourish the assault on Seoul. With this end in view, the 1st Shore Party Battalion reverted to Division control on the 19th and displaced from Inchon to Oeoso-ri. By nightfall the entire battalion was bivouacked in this area.

On the 20th, after establishing a forward CP at Kimpo Airfield, the shore party troops of Baker Company moved up to the Han in support of the 5th Marines, followed by two teams from Able Company. Evacuation stations and supply dumps were set up on both banks. Other shore party missions were maintaining LVT and DUKW traffic control, providing guides for the amtracs, posting security at the crossing sites on both banks, and effecting unit distribution of supplies upon request by the DUKWs and LVTs. Control of the ferry site, known as BAKER Ferry, became the responsibility of Baker Company of the 1st Shore Party Battalion. Teams 1 and 2 were employed on the south bank, and Team 3 plus headquarters troops on the other shore. Traffic control was of the utmost importance, since ferry operation had to be limited to periods of low tide, and during idle intervals a long line of vehicles accumulated. Most of them were trucks containing cargo to be reloaded in LVTs and taken across the river. The shore party men had the duty of keeping the traffic flowing as smoothly as possible, both on land and water, and special regulations were enforced to prevent the LVTs from colliding with the ferries. With the establishment of a third ferry, the problem of supplying the troops across the river was pretty well solved.[310] [310] 1st Mar Div _SAR_, Annex Mike Mike. _Command Ashore Assumed by X Corps_
