 Casualties among the American 1st Cavalry Division were relatively light. This division suffered a total of about 600 casualties, with around 200 killed in action, including those at Hill 303. American forces in established positions were able to decimate North Korean units crossing the Naktong in the open with their artillery fire and air attacks. The exact numbers of soldiers captured and executed compared with those killed in combat are difficult to determine, because of conflicting accounts of how many prisoners were actually held on Hill 303. The DPRK troops suffered much higher casualties, and also a much higher percentage of them killed in action (KIA). This included 2,500 at Yongp 'o, 500 at Hill 303, and 700 on Triangulation Hill. This places the total KIA at over 3,700 troops, though the exact number of casualties is unknown in the carpet-bombing operation because the patrols of the U.N. troops were unable to reconnitor this area until much later.
