Sutter ordered 2/1 to hold up at 1900 and dig in astride the highway. The 4,800-yard advance had cost the Marine unit four killed and 18 wounded, against 350 casualties and five prisoners for the North Koreans. Since all written and personal accounts agree that 19 September amounted to almost one continuous fire fight for the 2d Battalion, the amazing contrast in friendly-enemy loss figures must be attributed to the sound employment of Marine supporting arms.[334] [334] 2/1 _SAR_; Sutter-Codispoti interv, 25 Jan 55; and Cunliffe interv, 24 Aug 54. As mentioned earlier, 2/1’s positions for the night were a mile southeast of the 3d Battalion on Lookout Hill. Company E entrenched on high ground to the left of the highway--4,000 yards from Yongdungpo--while D and F manned a long, low hill on the right. Because the latter height ran parallel to the road, the line formed by Dog and Fox was at a right angle to that held by Easy. Sutter’s choice of this L-shaped defense would shortly prove to be an extremely wise one. _NKPA Counterattacks of 20 September_ The right flank of the 1st Marines was bare. Not until 1200, 19 September, did the 32d Infantry begin relieving 1/1 in its old positions southeast of Sosa. Liaison between the Marine and Army units at this time was weak. Apparently many of the Marines were unaware that General Barr’s OpnO No. 2,[335] for the 7th Infantry Division did not call for a jump-off by the 32d until 0630 on the 20th. At that time the Army regiment would attack a series of objectives which included Hill 146 and other high ground above the road.[336] Thus, the schedules north and south of the highway were running one day apart, and it would take the enemy himself to straighten the line when he slammed the gates of Yongdungpo.

Meanwhile, the 1st Battalion, 1st Marines, entrucked below Sosa for its circuitous journey from the right flank of the regiment to the left, where it was to relieve the 1st Battalion, 5th Marines, on Hills 118, 80, and 85. The 11-mile trip via Sosa and Wonjong-ni was uneventful, except that the troops had to dismount at the latter village and proceed on foot over the primitive road. With the first increment to arrive at Wonjong-ni, Captain Robert H. Barrow, commanding Company A of 1/1, set a rugged pace to get his troops on top of Hill 118 before dark. Relieving Company B of 1/5, he expected Charlie Company to pass through and replace its opposite of the 5th Marines on Hills 80 and 85.
