 While some Ashina forces withdrew across the Nippashi River to Kurokawa, the bridge gave out amidst their retreat, leaving many Ashina troops to be cut down when the Date forces overtook them.According to the 17th century text "Ōū Eikei Gunki," there were around 500 Ashina troops killed at the Nippashi River alone.This battle helped seal the Date clan's hegemony over southern Mutsu Province.
