Sweeney, from his OP on the southern slope of Observation Hill, tried to get an artillery mission on the two dominating peaks, but his forward observer was unable to contact the rear. Nor could the 4.2 mortar observer be located.
Faced with the necessity of giving his assault elements some protection, the company commander committed 2d Lieutenant Rodger E. Eddy’s 3d Platoon, sending it to the spur on the left of the village. Working its way up the nose which led to Hills 147 and 153, Eddy’s unit was able to concentrate its fire on the enemy-held peaks and relieve pressure on the other two platoons.
With enemy fire gradually increasing from new positions on the lower slopes of the ridge to the south of the village, Sweeney ordered the mortar section and all of his headquarters personnel into the valley to block the southern approach through the rice paddy. Leaving this flank guard in command of his executive officer, First Lieutenant Paul R. Uffelman, the company commander rushed to the base of the objective. Every single man in his unit was now committed.
Sweeney found the 2d Platoon leaderless and disorganized. The 1st had fought its way well up the slope, aided by excellent supporting fire from 2/5’s 81-mm. mortars. As that dogged group of Marines neared the crest, it was stopped when a friendly artillery barrage fell short, searing the skirmish line with white phosphorus.
1st NAKTONG COUNTEROFFENSIVE
SITUATION 17 AUG.—OBJ. 1 (OBONG-NI RIDGE)
Late morning found part of the company closing on the crest; but shortly before 1130, the attackers were ordered to pull back in preparation for an air strike by MAG-33. The planes came in quickly, and some of Company E’s men, within 25 yards of the summit, were caught in the strafing.
During the hammering by the Corsairs, the 3d Platoon slipped back 100 yards, leaving the critical left flank open to enemy-infested peaks 147 and 153. This time the hail of enfilade fire from Communist machineguns caught the remnant of Easy Company rifleman exposed on the higher slopes, and the Marine advance crumbled.
By noon on 17 August, the 2d Battalion, 5th Marines was wobbling. In 4 hours of fighting it had lost 23 dead and 119 wounded, practically all of the casualties being taken by the 2 rifle companies. Every officer in the Brigade could lament the lack of a third company in each battalion; for just when 2/5’s assault needed the added punch of a reserve unit, the outcome of battle had to rest on the failing strength of six depleted rifle platoons. The ridge could not be taken.
This was unfortunate, since there was clear evidence that the NKPA 4th Division was weakening. Although not apparent to the men of Companies D and E, their repeated attempts to carry the ridge had torn gaps in the enemy’s defenses. Bodies, weapons and wreckage were strewn along the entire northern crest.[302]
