Kō no Moroyasu

Kamakura, the capital, at the head of a large army. The goal was to secure the shōgun's control over the region, and prepare for an attack to the west, expanding the Shōgun's power. However, the Imperial Court sent its army, bolstered by warriors from across the country, against the shogunate and against Moroyasu and Moronao in particular. This army, led by Nitta Yoshisada, met Moroyasu's force on 10 December, and they fought again ten days later. After a number of skirmishes, Moroyasu's army, despite being reinforced by men under Ashikaga Tadayoshi, was defeated, and withdrew into the Hakone Mountains. Here, at Sanoyama and Mishima, another set of skirmishes took place, eventually resulting in the destruction of Nitta's Imperial force when the shōgun arrived with further reinforcements.^[2]

Hyōgo for Kyoto accompanied by Takauji, but they would never arrive.
