However, as with previous engagements, the superior range and firepower of the arquebus-armed Ashigaru soldiers inflicted heavy casualties on the crowded Korean forces while remaining out of range of the defender's bows and spears. Sin Rip did manage one cavalry charge, but found that various vegetation on the plain impeded his horses and that the Japanese forces also employed a considerable number of pikemen, who were able to break his charge before he could penetrate the Japanese lines. Sin Rip and a number of his commanders mounted on horses managed to escape the disaster; however, most of his men were cut down by the Japanese as they attempted to retreat. Sin Rip later killed himself to atone for the defeat by drowning himself in a spring a short distance from Chungju.
