The men went about their work under the floodlights, heedless of scattered enemy small-arms fire which continued throughout the night. At a glance the unloading presented a scene of noisy chaos, yet everything was so well under control by midnight that the accomplishment of the mission within prescribed time limits was assured. In the morning the eight LSTs were retracted according to schedule as a like number approached the beach to discharge cargo. Two of them grounded in the mud flats too far out for unloading, but the supply problem was already so well solved that this setback was not serious. On BLUE Beach it was not the intention to develop the area beyond the needs of the initial assault, so that a comparatively small shore party element was required. Only such equipment as could be carried by hand was taken ashore in the LCVPs and LVTs. The reconnaissance element of Shore Party Group B (--) had landed with the assault troops, followed by the rest of the group at 1930. Provisions for the use of pre-loaded LVTs having been made in the assault phase supply plan, the shore party troops set out flanking lights to mark the entire BLUE area as a single beach. This was in preparation for the arrival of the 24 LVTs bringing pre-loaded supplies to sustain the attack in the morning. Ten of these vehicles were so delayed by adverse currents that a receding tide left them high and dry. Officers of the 1st Marines decided that the supplies were not critical enough to warrant unloading by hand over the mud flats, and the job was postponed until the LVTs could be floated in on the morning high tide. While they were discharging on BLUE-3, the LCVPs came in with other gear which was unloaded and stored in the regimental dump. Prison stockades were set up on both beaches the first night. The LSTs continued to unload most of the Division supplies on RED Beach in spite of treacherous currents, the tidal range and the mistakes made by Japanese crews. BLUE Beach was closed on D-plus 1, having served its purpose, and the shore party personnel transferred to GREEN Beach, where facilities for unloading LSTs had been improved. Supplies landed there could be trucked across the causeway, and on D-plus 2 the shore party troops on RED Beach were also relieved and sent to Wolmi-do. The 2d Engineer Special Brigade retained control of all logistical operations in the Inchon port area on 17 September as vessels began to discharge at Pier No. 2, designated as YELLOW Beach. There were assurances by this time that the engineers would soon have the tidal basin partially operative, thus adding materially to the capacity of the harbor.[177] [177] 1st MarDiv _SAR_, Annex Mike Mike; Costigan interv, 17 Nov 54; K. W.
