Stories of the Japanese 00745 [Late Kamakura Period] The Battle of Karasaki Beach

The warrior monks of Enryaku-ji Temple clashed with the Rokuhara forces at Karasaki Beach.
Kaidō Sakon Shōgen of the Rokuhara side shouted,
"The enemy is small in number. Finish them off before their reinforcements arrive. Follow me, men!"
As he shouted this, he drew his large three-shaku-four-sun long sword and cut down three enemies from horseback.
However, a fierce monk from Enryaku-ji named Kaijitsu leaped at him, swinging a two-shaku-eight-sun naginata. It was a duel between two large men. Kaidō Sakon Shōgen appeared to be holding his own against Kaijitsu, but when he lost his balance, Kaijitsu's naginata pierced him, and he was easily killed. It is said that later at the Imperial Court, it became a topic of conversation that "it is a good omen that the surname of the first warrior defeated contains the character for 'East'." The Imperial Court must have referred to the shogunate as "Kanto" or "Azuma" (East).

While Kaijitsu was in high spirits after killing Kaidō Sakon Shōgen, a young boy with his hair tied up ran toward him from among the spectators who were watching from a distance. Kaijitsu was surprised and decided to ignore him, thinking, "I cannot fight such an innocent child," but the boy continued to attack him. Just as Kaijitsu was forced to deal with the boy, others shot arrows at him, and the boy was struck in the chest by an arrow and died.
This boy was Kōwakamaru, the heir of Kaidō Sakon Shōgen. Although his father had forbidden him from joining the battle, he had followed him out of love and longing for his father.
Seeing the way Kōwakamaru died, Kaidō's retainers were stirred to action. Thirty-six horsemen shouted,
"Take back our master's head!"
and began to fight, but Kaijitsu mocked them, saying,
"To think you would crave the heads of your own allies instead of the enemy's!"
and defeated the retainers one after another.
In this way, the Rokuhara forces, unfamiliar with the terrain, were shot down one after another by arrows from the Enryaku-ji side in the narrow paths and died in battle, and the remaining soldiers retreated.
The warrior monks, happy with their victory, said,
"We are safe now. Let us move the Emperor, who is at Sai-in, to the main temple."
They guided the Emperor's procession, but a sudden gust of wind blew up the bamboo blinds, revealing that the person riding was not Emperor Go-Daigo, but Kazan'in Morokata.
The warrior monks were completely dumbfounded and stopped their escort, losing all will to fight, and their hearts turned away from Prince Son'un. Prince Son'un and Kazan'in Morokata gave up, thinking, "So this is as far as our decoy operation goes," and descended Mount Hiei to head toward Mount Kasagi.
