[[Asakura Yoshikage]], the head of the Asakura clan and regent of [[Ashikaga Yoshiaki]], refused to come to Kyōto. This caused Nobunaga to declare both of them rebels.<ref name=Sansom2>{{Cite book |last=Sansom |first=George |title=A History of Japan, 1334–1615 |publisher=Stanford University Press |year=1961 |isbn=0804705259 |page=281}}</ref> Several reports from ''Mikawa Monogatari'', ''Nobunaga Koki'', ''Tokugawa Jikki'', and a supplement from ''Ietada Nikki'' recorded that Ieyasu and his forces also participated in Oda's punitive campaign against Asakura, in which they captured Mount Tenzutsu castle. The Oda-Tokugawa forces managed to kill 1,370 enemies on April 25. 

They continued the next day by [[Siege of Kanegasaki (1570)|besieging Kanegasaki castle]].<ref>{{cite web |author1=小野 雅彦 |title=家康も撤退を知らされていなかった「金ヶ崎の退き口」 |url=https://www.rekishijin.com/27174 |website=Rekishijin |publisher=ABC ARC, inc. |access-date=10 June 2024 |language=Ja |date=2023 |quote=。織田・徳川連合軍は敵の首1370を討ち取るなどして城を攻め落とし（『家忠日記増補』）}}</ref> However the [[Azai clan]] sent reinforcements to relieve the siege so Nobunaga retreated without contacting Ieyasu. After dawn, Ieyasu withdrew from battle guided by Kinoshita Tokichi (later named [[Toyotomi Hideyoshi]]), an Oda vassal.<ref>{{cite web |author1=Koichiro Hamada (濵田 航一郎)  |title=金ヶ崎合戦、姉川の戦いで徳川家康は一体どうした⁉ |url=https://www.rekishijin.com/26842 |website=Rekishijin |publisher=ABC ARC, inc. |access-date=10 June 2024 |language=Ja |date=2023 |quote=。織田・徳川連合軍は敵の首1370を討ち取るなどして城を攻め落とし（『家忠日記増補』）}}</ref>

Later, in July 1570, the brother-in-law of Nobunaga, [[Azai Nagamasa]], who had broken his alliance with the Oda clan during the siege of Kanegasaki, and Asakura combined to fight the combined armies of Nobunaga and Ieyasu, who led 5,000 of his men to support Nobunaga at the battle.<ref name=Turnbull/>{{rp|62}} As the Oda clan engaged the Azai clan army on the right, Tokugawa's forces engaged the [[Asakura clan|Asakura clan's]] army on the left. At first, Asakura's army gained the advantage as they steadily pushed back the Tokugawa army.
