This army, commanded by [[Toyotomi Hideyoshi|Hashiba (Toyotomi) Hideyoshi]], first invaded Harima and after forcing the submission of the Akamatsu besieged the Bessho clan at [[Miki Castle]]. Ukita led forces into Harima and clashed with the Oda soldiers, capturing [[Kozuki Castle]], a place subsequently lost to [[Yamanaka Shikanosuke]]. A relief effort in [[1579]] ended in a defeat for the Ukita and in [[1580]] Naoie signed a treaty with the Oda.
