the eight LSTs took some hits from mortar and machine gun fire, which killed a sailor and injured a few others. The LSTs completed unloading and cleared the beach at high tide early on 16 September. After neutralizing KPA defenses at Incheon on the night of September 15, units from Red Beach opened the causeway to Wolmi-do, allowing the 3rd Battalion, 5th Marines and the tanks from Green Beach to enter the battle for Incheon. Blue Beach The 1st Marine Regiment, under the command of Colonel Lewis "Chesty" Puller, landed at Blue Beach, southeast of Red and Green beaches. Their mission, once the beach was secure, was to capture the suburb of Yongdungpo, cross the Han River, and form the right flank of the attack on Seoul itself. As the 1st Marine Regiment approached the coast, the combined fire from several KPA gun emplacements sank one LST. Destroyer fire and bombing runs silenced the KPA defenses. When the Blue Beach forces finally arrived, the KPA forces at Incheon had already surrendered, so they met little opposition and suffered few additional casualties. The 1st Marine Regiment spent much of its time strengthening the beachhead and preparing for the move inland.

Early that morning of September 16, Lieutenant Colonel Murray and Colonel Puller had their operational orders from 1st Marine Division commander General Oliver P. Smith. The 1st Marines and 5th Marines began moving along the Incheon-Seoul road. Early morning on September 16, the 5th Marines (from Red and Green Beaches) started generally east along the Incheon-Seoul road, intending to link up with the left of the 1st Marine Regiment so both regiments could move on Seoul. Six solitary T-34 tanks moving west towards Incheon appeared as the advancing 5th Marines reached the village of Kansong-ni. A strike force of eight Marine F4U Corsairs from VMF-214 attacked the tanks, destroying two and driving the others off. M26 Pershing tanks of the 1st Tank Battalion destroyed three more KPA tanks shortly thereafter. South of the 5th Marines, the 1st Marines, having spent most of the day consolidating its scattered units, did
