Masamune Date, who was leading the campaign, defeated Ujisato Gamo at the Oyamada River in Mutsu, declared his parting of the ways with Hideyoshi, and pacified the northeastern part of Japan. In response, Hideyoshi organized a second military force of over 70,000 troops from the western provinces, including Kiyomasa Kato, Shimazu, and Chosokabe, with Hidetsugu Toyotomi as commander-in-chief. However, the army was destroyed before it reached Ou due to the treachery of Tokugawa Ieyasu at Mikawa on the way to the capital. A secret alliance had been formed between Date and Tokugawa! Furthermore, Masamune persuaded the Uesugi family to join the Hojo family, which had been restored by Hojo Ujinao, and an alliance of the four feudal lords of eastern Japan was formed. The four feudal lords of the eastern provinces formed an alliance, including the Hojo family, which had been restored by Hojo Ujinao.
