賤ヶ岳の戦い
Nobunaga's death in 1582 caused open hostilities between Shibata Katsuie and Hashiba Hideyoshi over the issue of succession. Katsuie's forces were defeated at the Battle of Shizugatake, and he was forced retreat to Kitanosho castle. With Hideyoshi's army laying siege to his home, Katsuie set the castle ablaze; he and Oichi perished in it.
