The three conspirators were defeated at the Battle of Inō, but they were pardoned after the intervention of Tsuchida Gozen, the birth mother of both Nobunaga and Nobuyuki. The next year, however, Nobuyuki again planned to rebel. When Nobunaga was informed of this by Shibata Katsuie, he faked illness to get close to Nobuyuki and assassinated him in Kiyosu Castle.
