姉川の戦い
In 1570, while Oda–Tokugawa coalition fought at the Battle of Anegawa against the Asakura and Azai clans, Katsuie was at Chōkō-ji castle, under siege by 4,000 soldiers of the Rokkaku clan. Katsuie eventually won via an all-out attack, forcing the Rokkaku to retreat. This action, along with a series of brilliant victories, gained him renown as the "Oni Shibata", or "Demon Shibata".
