2. 1575Shitara Plain battlefield · Aichi PrefectureThe Takeda army launched repeated cavalry assaults but suffered heavy losses before the Oda-Tokugawa allied segmented volleys and obstacle works. Senior Takeda retainers Yamamoto Kansuke, Hara Masatane, Naitō Masahide, Saitō Morishige and others were killed, and Takeda Katsuyori was forced to order a retreat.
3. 1575Toward Kai and Tōtōmi · Chūbu regionThe disastrous defeat at Nagashino severely weakened the Takeda army's elite and the cohesion of its retainers; the Oda-Tokugawa alliance subsequently nibbled away at Takeda domains, laying the groundwork for the destruction of the Takeda clan more than a decade later.
