Siege of Akechi

Battle
Despite the death of Takeda Shingen in 1573, the Takeda, now led by Katsuyori, continued to make gains against the Oda and Tokugawa. In March 1574 Katsuyori led an army into Mino Province and surrounded Akechi castle. Nobunaga hastily dispatched a relief force under his eldest son Nobutada and Ikeda Nobuteru but this arrived too late: Akechi's commander had already surrendered. Later that year, Katsuyori would score another victory by taking Takatenjin castle in Totomi province. This would be the Takeda's high-water mark, which would recede following the Battle of Nagashino in 1575.
