Battle of Bubaigawara

After his victory three days earlier at the Battle of Kumegawa, Nitta Yoshisada took time to rest his horses and men. Meanwhile, the forces loyal to the Shogunate retreated to Bubaigawara to regroup. Unbeknownst to Nitta, the Shōgun's forces had received reinforcements on the 14th greatly restoring strength and morale.

As the Imperial forces advanced on Bubaigawara on the 15th, the Shōgun's forces attacked with a great archery barrage and thus halted the Imperial attack. The main body of the Shōgun's army then engaged Nitta's army, and despite aggressive counterattacks by Nitta, heavy losses forced Nitta to retreat.[1]

Had the Shogunate forces immediately pressed their advantage of the first day, it was likely their victory would have been complete. However, during the night of the 15th, Nitta received critical reinforcements led by Miura Yoshikatsu. And at dawn on the 16th, Miura led his fresh troops and attacked an unsuspecting enemy. Nitta Yoshisada and his brother Nitta Yoshisuke advanced to the front while Miura harassed the enemy from the rear.[1]

The battle resulted in a rout in favor of the Nitta brothers and Miura. Although the Shogunate forces held the initial advantage, their failure to exploit it led to defeat.[2]

The remnants of the Hōjō forces retreated in disarray to Kamakura where they regrouped. The forces led by Nitta pursued and were victorious during the Siege of Kamakura.[2]
