Then, Magara Jurozaemon Naotaka, the strongest warrior of Asakura clan was kill. Kagetaka lost his control of his army and retreated to Echizen.

At the same moment, Nagamasa broke 11 Nobunaga's units out of 13 units. Nobunaga was thinking his defeat again. However, as soon as Ieyasu defeated Asakura, he attacked Nagamasa from the side. Nagamasa couldn't hold the attack, and he also retreated to Odani Castle.

Nobunaga wanted to attack Odani castle and kill Nagamasa, but Odani castle was well known as the hardest mountain castle. So, he left Hashiba Hideyoshi to surround this castle.

2 years later, both Nagamasa and Asakura clan was abandoned by Nobunaga.
