MARINE ATTACKS
D-PLUS 1
The Inchon-Seoul Highway remained the boundary between the 1st and 5th Marines. Lieutenant Colonel Murray’s order went out to the latter before noon, directing a two-pronged assault. The 2d Battalion would jump off from the O-3 Line and trace the course of the highway, clearing the hills and villages on the left. Simultaneously, the 3d was to swing sharply northward from behind 2/5 and attack high ground overlooking the east-west leg of the FBHL. The 1st Battalion would remain in regimental reserve.[192]

There were a number of reasons why Colonel Puller’s scheme of maneuver was more complex. Not only was the 1st Marines’ front much wider and the terrain more difficult, but the rapid advance had left troops units scattered throughout a zone of action some 15 square miles in area. There was considerable shuffling to be done before the regiment could deploy along the highway for the drive to the east.
The 2d Battalion would continue along the MSR, clearing the high ground on the right and coordinating with 2/5 on the left. To the south, the 1st Battalion would move up on the right of the 2d as quickly as the rugged terrain allowed. The 3d, after clearing the Munhang Peninsula, was to pass into regimental reserve subsequent to being relieved on the right flank by the Reconnaissance Company. Swinging around a sharp cove of salt pans and mud flats, the latter unit would patrol the Namdong Peninsula to secure the Division right.[193]

At 1335, the 5th Marines attacked against minor resistance on the north of the highway. Moving into Kansong-ni, the vanguard of 2/5 and its tank escort approached a sharp bend where the road veered northward for about a mile to avoid two large hills. Around the curve were the enemy tanks believed to have been knocked out by VMF-214 earlier in the day.
A section of Marine armor turned left off the pavement just short of the bend. The two M-26s crawled to the top of a knoll from which they could cover the infantry, as the latter advanced around the corner. Looking down from their vantage point, the tank crews saw three intact T-34s parked in column on the highway, about 300 yards beyond the turn. Hatches on the Communist vehicles were buttoned, with the 85mm guns leveled at the road bend.[194]
