Ujiyasu Hojo and 346 Hojo troops besieged Hojo Castle, held by Norikatsu Ogigayatsu and 303 troops, after failing to do so in the earlier parts of the year. The Hojo failed in their first attack, losing 224 troops, but killed the enemy down to 24 men. The Hojo continued the siege until reinforcements from Morotsugu Kasahara (brother of Ujitane Kasahara, slain in the first siege) arrived, and they advanced into the castle. They had 250, facing 71 enemies. The Hojo lost 109 more troops, but slaughtered the rest of the Ogigayatsu, slaying Norikatsu and devastating the Ogigayatsu.
