Sanada's army defeated Echizen Matsudaira's army, attacked the headquarters of Ieyasu and defeated hatamoto (direct retainers of the bakufu, a form of Japanese feudal government headed by a shogun) of Ieyasu, who were famous for their brawniness (it is said that it was the second time since 'the Battle of Mikatagahara' when Ieyasu's headquarters was attacked and Uma-jirushi (massive flags used in Japan to identify a daimyo or equally important military commander on the field of battle) was brought down and Ieyasu prepared to kill himself, having seen the fierceness of Sanada's army; time was vengeful, and Ieyasu's uma-jirushi was brought down twice by commanders related to the Takeda family).
真田勢は越前松平勢を突破し、家康の本陣まで攻め込み、屈強で鳴らす家康旗本勢を蹴散らした（ちなみに、本陣に攻め込まれ馬印が倒されたのは「三方ヶ原の戦い」以来二度目と言われ、真田勢の凄まじさに家康は自害を覚悟したほどだったという。これにより、奇しくも家康は武田家ゆかりの武将に二度馬印を倒されたこととなる）。
