Battle of Mikatagahara

Timeline

1. 1572–1573Tōtōmi Province · Shizuoka PrefectureTakeda Shingen left Kai with about 30,000 men under the pretext of a march to Kyoto, invading Tōtōmi via Suruga; Tokugawa Ieyasu was forced to give battle before Oda reinforcements could fully assemble.
2. 1573Mikatagahara plain · Shizuoka PrefectureTakeda cavalry and the Furinkazan formation launched a fierce assault at Mikatagahara; the Tokugawa lines collapsed, with Honda Tadakatsu and other senior retainers fighting hard to cover the retreat, and many Tokugawa soldiers were killed or scattered—later called Ieyasu's 'only great defeat in his life.'
3. 1573Hamamatsu Castle · Shizuoka PrefectureTokugawa Ieyasu withdrew into Hamamatsu Castle to regroup; although victorious, the Takeda did not destroy the Tokugawa in one stroke, and Shingen then continued west to the Noda Castle line until falling ill and dying the same year.
