Meanwhile, Katsuie won over Motochika CHOSOKABE of Shikoku and Saigashu (Ikko adherents of Saiga) of Kii Province, the latter of which especially threatened the rear regions through actions such as attacking castles including Kishiwada-jo Castle in Izumi Province while Hideyoshi was on another battlefield.
一方で勝家は四国の長宗我部元親や紀伊国の雑賀衆を取り込み、特に雑賀衆は秀吉の出陣中に和泉国岸和田城などに攻撃を仕掛けるなど、後方を脅かしている。
