 Command of the attack on the castle itself was assigned to Gamo Ujisato, assisted by Asano Nagamasa.Within Kunohe Castle, Kunohe Masazane had only 5,000 defenders but due to his strong defensive position with three sides of his castle protected by rivers, he rejected initial offers that he surrender.However, he was so strongly outnumbered that after only four days he agreed to a proposal made by a trusted family priest that the defenders would be pardoned if they surrendered.
