賤ヶ岳の戦い
Although he was married to Nobunaga's younger sister, Oichi, this did not prevent Hideyoshi from invading the following year. After his forces were defeated at the Battle of Shizugatake, Shibata withdrew to Kitanoshō Castle, which was subsequently destroyed in 1583. A few stone foundations of the castle were uncovered in archaeological digs and are now open to the public.
