INTERACTIVE BATTLE
September 1560 · Norada in Ōmi Province (now Norada and Hida, Hikone)
Azai Nagamasa marched to relieve Hida Castle, under attack by the Rokkaku, and beat the army of Rokkaku Yoshikata across the Uso River. The battle was the turn at which the Azai became independent of the Rokkaku.
Under Hisamasa the Azai had submitted to the Rokkaku of southern Ōmi. The Shiga Prefectural Board of Education records that his son Nagamasa, with retainers who resented this, forced Hisamasa into retirement. Hida Castle, held by the Takanose on the Rokkaku side, had been attacked by flooding the year before, and the border between the two houses was in dispute.
The Rokkaku were beaten, and Azai Nagamasa came to rule northern Ōmi as his own domain. Three years later the Rokkaku house was thrown into disorder by the Kannonji affair.
