The Hōjō tried a risky tactic, coordinating a night attack between the garrison and the relieving force. Going against battlefield custom, the samurai were ordered to leave behind any heavy armor, which would slow them down and perhaps reveal their position, and to not bother taking the heads of their defeated enemies. This would deny the warriors much honor, as their triumphs would not be known or recorded, but the intense loyalty of the Hōjō samurai caused them to follow these orders. The tactic succeeded, Uesugi Tomosada was killed in battle, and the Hōjō foiled the siege.
