The 1st Combat Service Group remained in control of consolidated dumps. This organization was the storage agency for all X Corps supplies with the exception of ammunition and engineering materials, both of which were handled by Army personnel. Owing to the shortage of trucks, the 7th Motor Transport Battalion was held in the port area under control of the engineer brigade. The lack of enough motor trucks for port operations was alleviated by the restoration of rail transportation much sooner than had been expected. Although the planners did not count on this factor before D-plus 30, the 2d Engineer Special Brigade rounded up Korean crews and speeded up the tremendous task of putting the Inchon-Seoul line back in working order. As early as D-plus 1 a switch engine and six cars were operating in the Inchon yards. Three days later the first train, carrying 1,200 Marines, was dispatched over the 5-mile run from Inchon to Ascom City. As the ground forces advanced, the engineers followed close behind the front with rail transportation which handled a total of 350,000 rations, 315,000 gallons of fuel, 1,260 tons of ammunition, and 10,000 troops before the Division was relieved. _Surgical Teams on the Beaches_ Casualties of the Landing Force on D-day amounted to 20 KIA, 1 DOW, 1 MIA, and 174 WIA in addition to 14 of non-battle classification. Medical officers regarded the operation as a landmark because of the four Navy surgical teams, each composed of three doctors and ten corpsmen, which went in behind the assault troops on the LSTs. Similar teams had been employed in the later operations of World War II, but Inchon had the distinction of being the first amphibious assault in which carefully planned medical techniques were integrated with military operations. The surgical teams had been drilled and rehearsed in Japan for their tasks. Patients requiring immediate surgery on the night of D-day were evacuated to LST(H) 898, where an improvised operating room had been installed. During the assault phase, 42 military and 32 civilian casualties were treated instead of the 300 which had been expected. Such an unqualified success was achieved that the teams were recalled to Japan afterwards to act as instructors. Within a year the numbers of Navy surgical teams had grown to a total of 22 on standby duty in the Far East.[178] [178] Capt E. R.

From a study of maps and intelligence reports, he tentatively selected a site for the Division hospital on the eastern outskirts of Inchon.
