An obstacle in southern Ōmi Province was the Rokkaku clan, led by Rokkaku Yoshikata, who refused to recognize Yoshiaki as "shōgun" and was ready to go to war to defend Yoshihide. In response, Nobunaga launched a rapid attack of Chōkō-ji Castle, driving the Rokkaku clan out of their castles. Other forces led by Niwa Nagahide defeated the Rokkaku on the battlefield and entered Kannonji Castle, before resuming Nobunaga's march to Kyoto. Later in 1570, the Rokkaku tried to re-take the castle, but they were driven back by Oda forces led by Shibata Katsuie. The approaching Oda army influenced the Matsunaga clan to submit to the future Shogun. The daimyo Matsunaga Hisahide kept his title by making this decision to ally his clan with the shogun.
