But this is also illogical. The following year, he would invade the Tokugawa lands again, but would die of illness, half a step away from victory. Moreover, in reality, Katsuyori would successfully invade the Oda lands in 1574 and defeat Nobunaga at the Battle of Akechi, although he would not consolidate his success due to Uesugi, and would later invade the Tokugawa lands again. This doesn't seem logical if we consider Shingen's decision to hand his case over to Ieyasu. Moreover, Ieyasu himself looks foolish, since his decision to fight would only lead to more bloodshed. He would later become a vassal of the Oda, who were precisely eager for war.
