Ukita Hideie
Toyotomi's forces arrived 113,000 strong under Toyotomi Hidenaga, Toyotomi Hidetsugu, Ukita Hideie and the Mōri clan's "Two Rivers", Kobayakawa Takakage and Kikkawa Motoharu. Opposing them were 40,000 men of Chōsokabe's. Despite the overwhelming size of Hideyoshi's army, and the suggestions of his advisors, Motochika chose to fight to defend his territories. The battles culminated in the siege of Ichinomiya Castle, which lasted for 26 days. Chōsokabe made a half-hearted attempt to relieve his castle from the siege, but surrendered in the end. He was allowed to keep Tosa Province, while the rest of Shikoku was divided among Hideyoshi's generals.
