Complying with Eighth Army's order for what was in effect a spoiling attack against the North Koreans northwest of Taegu, General Gay on 1 September ordered the 7th Cavalry to attack the next day and seize enemy-held Hill 518. Hill 518 (Suam-san) is a large mountain mass five miles northeast of Waegwan and two miles east of the Naktong River. It curves westward from its peak to its westernmost height, Hill 346, from which the ground drops abruptly to the Naktong River. Situated north of the lateral Waegwan-Tabu-dong road, and about midway between the two towns, it was a critical terrain feature dominating the road between the two places.
After securing Hill 518, the 7th Cavalry attack was to continue on to Hill 314. Air strikes and artillery preparations were to precede the infantry attack on 2 September. Forty pieces of artillery, four-fifths of that available to the 1st Cavalry Division, were to support the attack. [22-35]
