Toyotomi Hidetsugu
With a large number of Nanbu "samurai" in the south serving in Hideyoshi’s forces against the Odawara Hōjō, the rebellion soon spread to many locations by 1591. Hideyoshi and Tokugawa Ieyasu took the rebellion as a personal affront to Hideyoshi's authority and efforts to bring the Sengoku period to a close. By mid-year, they had organized a retaliatory army to retake northern Tōhoku and to restore the area to Nobunao’s control. The army had 60,000 troops and a cast of the most famous generals in the late Sengoku period under Tokugawa Ieyasu, including Toyotomi Hidetsugu, Uesugi Kagekatsu, Maeda Toshiie, Ishida Mitsunari, Satake Yoshishige, Date Masamune, Mogami Yoshiaki, and Tsugaru Tamenobu. The army quickly suppressed the rebellion in many locations and reached the gates of Kunohe Castle by 2 September 1591.
