Shiba Ienaga
Shiba Ienaga (1321–1338) was the eldest son of Shiba Takatsune and fought for Ashikaga Takauji from boyhood. In 1335 he was named commander-in-chief of Ōshū, holding the front against Kitabatake Akiie's Southern Court Mutsu government from Takamizushiro castle in Shiwa.
He then served as Kantō steward at Kamakura, assisting the young Ashikaga Yoshiakira and eroding Akiie's authority among the warriors of the north. In December 1337 he tried to stop Akiie's army before Kamakura and was killed at the battle of Sugimoto castle, aged seventeen.
