Soon, in 1573, Oda Nobunaga is mobilizing his forces to attack Azai Nagamasa, continuing his campaign in central Honshu to maintain his control of Kyoto against the growing opposition. When the Tokugawa and Oda clans launch an attack on Takeda territory, Katsuyori begins a counter-offensive against the advice of other generals. The "kagemusha" is forced to lead reinforcements to the 1574 Battle of Takatenjin, and helps inspire the troops to victory. In a fit of overconfidence, the "kagemusha" attempts to ride Shingen's spirited horse. When he falls off, those who rush to help him see that he does not have their lord's battle scars, and he is revealed as an impostor. The thief is driven out of the palace in disgrace, and Katsuyori takes over the clan. Oda and Tokugawa, sensing weakness in the Takeda clan leadership, are emboldened to begin a full-scale offensive into the Takeda homeland.
