How the battle unfolded

  1. Siege Eighty Thousand Around the Castle

    Since Tenbun 14 an allied army of 80,000 under Uesugi Tomosada of the Ōgigayatsu, Uesugi Norimasa of the Yamanouchi and the Koga kubō Ashikaga Haruuji has surrounded the Hōjō castle of Kawagoe many ranks deep. Its defender is Hōjō Tsunashige with a mere 3,000. The siege has lasted half a year.

  2. Relief Ujiyasu Humbles Himself

    Hōjō Ujiyasu hurries from Odawara to the rescue. But he has only 8,000 men. Facing an enemy ten times his size, Ujiyasu avoids a frontal battle, sends humble envoys to sue for peace and at times feigns retreat, inviting the enemy's complacency.

  3. Ease A Great Army Grows Slack

    The long siege, the overwhelming numbers and Ujiyasu's timidity. Complacency has spread through the allied army. Nightly feasts, slack watches; as good as victorious already, the great army sinks into deep sleep.

  4. Raid Take No Heads, Just Run

    The dead of night, the 20th day of the 4th month. Ujiyasu orders the whole army, "Take no heads, just run," and in light gear they pour into the allied camp. At the same moment Tsunashige throws open the castle gates and sallies out shouting, "Victory, victory!" A pincer attack.

  5. Rout Collapse in the Dark

    Taken by surprise, the great army collapses, fighting itself in the darkness. Uesugi Tomosada of the Ōgigayatsu is killed in the melee, and the noble house of the Ōgigayatsu Uesugi is destroyed here. Nanbata Norishige too is said to have died after falling into a well in the dark.

  6. Dawn The Night of the Three Great Surprise Attacks

    Uesugi Norimasa and the kubō Haruuji both escape the field with their lives and little else. This night battle in which 8,000 beat 80,000 is counted with Okehazama and Itsukushima among the "three great surprise attacks of Japan," and it settled Hōjō mastery of the Kantō.
