Teruhi entreats her followers to support the Toibarai in their defense of Kanatanoki, although outnumbered almost six to one. They concentrate most of the forces at the main South Gate, while Shiraishi offers to defend the west wall at the rear. Meanwhile Mongol Commander Choukuru speeds to be the first to attack the defenders but runs into a trap laid by Jinzaburou and a small Toibarai force. Choukuru's force is drawn to attack the heavily defended South Gate, but are stopped by the experienced defenders. Commander Funbishi then arrives with orders to keep the defenders fully occupied while Commander Ochirubato circles around to the west wall. Meanwhile Shiraishi sends the Toibarai soldiers from the North Gate to the South Gate, allowing the Mongols to scale the wall and enter. However, Ochirubato falls into a trap, and is burned along with his men, giving the impression that the citadel is ablaze. While the Mongols hesitate, Jinzaburou leads a cavalry charge into their midst, almost killing Uriyan Edei who decides to withdraw and focus on their main objective, the conquest of Japan. When the breach at the west wall is discovered, Jinzaburou goes to investigate, and finds the traitor Shiraishi waiting for him.
