Today, the Imagawa family's offensive reached a new level as they launched a fierce attack along the entire front. Intense fighting broke out at several critical points—North Mountain, the rock fortresses by the river, the rammed earth wall, and "Stone City." Harano judged that the enemy was about to deliver a decisive blow, so he made full preparations, committing all available front-line forces onto the city walls.
At the same time, he also drafted contingency plans in case the rammed earth wall was breached and their rear lost its shield—preparing for a contraction of the defense. Should the wall fall, he was ready to abandon the North Mountain Rock Fortress, withdrawing the more than one hundred Wanjin Army soldiers left there back to the port rock fortress for defense.
