Two smaller hills, 702 and 602, spread off southeast and northeast respectively to the Soyang River and its unnamed tributary from the west. On either side of YOKE Ridge were numerous sharp and narrow ridges. Some of the hills were wooded with enough scrub pine to afford concealment for outposts and bunkers. Altogether, it was an area eminently suited to defense. The defenders were identified by Division G-2 as troops of the 6th Regiment, 2d Division, II NKPA Corps. Apparently they did not lack supporting weapons, for 3/7 positions on Hill 680 were hit by an estimated 200 mortar and artillery rounds during daylight hours of the 30th. [Illustration: MAP 17 AREA OF 1st MAR DIV ACTIVITY SEPT 1951 FRONT LINES 30 AUG 51 ON KANSAS OBJECTIVE LINE HAYS] _Crossing the Soyang in Flood_ The 7th Marines and KMC Regiment, ordered to relieve U.S. and ROK Army units on the KANSAS Line, started their march in a downpour on 27 August. The 5th Marines (less 1st Battalion) at Inje had orders to follow the 7th up the narrow Soyang valley. Typical of the wet weather difficulties were those experienced by 3/7. Scheduled to depart early for the forward positions, the companies struck tents. Trucks failed to arrive and they remained to eat the noon meal, a gustatorial bonus of all food the galley crew could not carry with them. Unfortunately, the trucks were delayed further and the men shivered in the rain as they ate an evening meal of “C” rations. When the vehicles finally arrived at 2100 the rain had reached torrential proportions. Progress was so slow over muddy roads that it took until 0330 on the 28th to reach the CP of the 7th Marines at Sohwari (Map 18), just southeast of the junction of the Soyang and a tributary from the east. The bivouac area assigned to 3/7 for the night proved to be a foot deep in water, and Lieutenant Colonel Kelly directed his men to catch what sleep they could in the trucks while he and his staff attempted to straighten out the snarled traffic situation.[271] [271] Sources are 1stMarDiv _HD_, Aug 51, 3–5; Col B.

It took the rest of the night for the 3/7 officers to walk the length of the convoy, cutting out trucks with less essential cargo. With only a small space available for a turn-around, the 3/7 vehicles were ordered to back into it, unload their troops and equipment, and return along a narrow road, which had been churned into a quagmire.
