The 7th Marines put in a busy day at seizing objectives which consisted of the high ground north of Seoul on both sides of the main highway from the capital to Uijongbu. Opposition was light to moderate, with the stiffest resistance occurring in areas which indicated that the enemy intended to put up a fight to protect his escape route to Uijongbu. Seventy-five tons of American-made dynamite and explosives, captured by the 7th Marines, were believed to have been originally supplied to the ROK forces before the war and abandoned during the NKPA invasion.[451] Total advances for the day ranged from 1,500 yards in the zone of the 3d Battalion to 2,600 yards in the zone of the 2d Battalion.

The 3d Battalion remained in an assembly area in the rear and continued mopping up along with the 2d KMC Battalion. Although organized resistance in the city had been broken, the 1st Battalion met stubborn resistance from enemy groups and encountered many mines. The 2d Battalion, on the left, made headway against light opposition. These attacks cleared the remainder of Seoul and took the assault battalions to Hill 133 (Objective ABLE) commanding the city on the northeast.[452] [452] _Ibid._, Annex Peter Peter. General Smith visited the CPs of all three regiments on the 28th by helicopter. He found Colonel Puller at the Ducksoo Palace, near the intersection of the streetcar lines. Colonel Litzenberg’s CP was located a short distance to the west, and Lieutenant Colonel Murray had established his headquarters in the Women’s University on the northwest outskirts of the city. Later that day Generals Smith and Craig displaced the Division CP from Oeoso-ri to a barracks area in Seoul, southwest of South Mountain. The two Marine generals took over a former infirmary, but they decided that the mortuary slab was too depressing and had that fixture removed.[453] [453] O. P. Smith, _Notes_, 308, 338–339. _Liberation Ceremonies at Seoul_ Planning for impressive liberation ceremonies at Seoul had begun while the street fighting was at its height. The 1st Marine Division was requested by Corps to furnish two honor guards and a band. Musical instruments having been left behind in Japan, air shipment was prescribed.[454] [454] O. P.
