Cause

During the Nanboku-chō Wars, the Kuromaru fortress in Echizen Province served as a stronghold for Shiba Takatsune. The Southern Court sought to reduce Ashikaga-aligned fortifications, prompting Nitta Yoshisada to lead a small mounted force against it in August 1338.

Event

Nitta Yoshisada attacked the Kuromaru fortress with roughly fifty horsemen in what became the Battle of Fujishima. Warrior monks who had joined his force were bribed by Shiba to defect, and as Nitta moved to close the gap in his lines, his cavalry collided with Hosokawa Akiuji's troops. Nitta was struck by an arrow and mortally wounded in the engagement.

Consequence

Nitta Yoshisada's death was a significant loss for the Southern Court. The following year, newly enthroned Emperor Go-Murakami ordered Nitta's brother, Wakiya Yoshisuke, to resume the attack. This second assault succeeded, compelling Shiba Takatsune to surrender and ending the fortress's role as an Ashikaga stronghold.
