1583: The Battle of Shizugatake—Hideyoshi Defeats Shibata Katsuie - Sengoku Shogun Map
Hashiba Hideyoshi, at odds with Shibata Katsuie over the succession to Oda Nobunaga and Katsuie's backing of Oda Nobutaka, clashed with Katsuie's army at Shizugatake in Ōmi. When Maeda Toshiie's forces withdrew from the Shibata line, Katsuie's army collapsed entirely; he retreated to his base at Kitanoshō Castle and took his own life. Hideyoshi thereby effectively secured his position as Nobunaga's successor.
