Historically, Nobunaga was the Asakura family or the Asai family who fought first?

In April 1570, Nobunaga broke his alliance with Asai Nagamasa in order to defeat the Echizen daimyo Asakura Yoshikei, who had ignored Kamiraku's orders several times, and began to march towards Echizen with the allied Tokugawa Ieyasu army. The Oda Tokugawa army gradually attacked the various castles of the Asakura clan, and when it reached Kanesaki, Asai Nagamasa, an ally of Kita Omi, attacked the Oda Tokugawa coalition army from behind. As a result, Nobunaga fell into a sudden crisis, and was finally able to escape back to Kyoto under the efforts of Kinoshita Hideyoshi (renamed by Fujiyoshiro), Tokugawa Ieyasu, and others (known as the Kanesaki Retreat).

In June 1570, at Omi Kawakawa Kawara, he united with the Tokugawa Ieyasu army against the Asai and Asakura combined forces (Battle of Yakawa) and defeated the Asai Asakura combined army. In August of the first year of Tensho (1573), Nobunaga ordered Hosokawa Fujitaka to defeat one of the Miyoshi trio guarding Yodo Castle, and Yumi was defeated. In the same month, Nobunaga marched to Echizen with 30,000 troops and defeated the Asakura army at the Battle of Tonezaka.

After conquering the Asakura clan, he turned to attack Asai Hisamasa and Nagamasa, father and son, who were attacking Otani Castle, and destroyed the Asai clan. At this time, he brought back Nobunaga's sister Aichi, who was married to Nagamasa.

The Asakura family who fought first, but Asakura and Asai were world friends, and out of morality, Asai helped Asakura and broke with Nobunaga.

Hit Asakura first, and at this time, Asai Nagamasa sneaked up behind his back, and since then he has formed a bond with Asai. After that, he defeated the Asai Asakura coalition and destroyed Asakura and Asai successively.

Battle of Sister River

In June 1570, Oda Nobunaga avenged his revenge for being flanked by Asai and Asakura, and led his headquarters and the Tokugawa Allied Shin side army to attack Asai Nagamasa. As a result, the Oda Tokugawa coalition army and the Asai Asakura coalition army met at the sister river and set up a formation across the river.

Oda Gun's six forwards of Masano Sakai, Tsuneko Ikeda, Hideyoshi Hashiba, Katsuie Shibata, Konari Mori, and Nobumori Sakuma were deployed along the sister river. Oda Nobunaga commanded the main camp, and there were also the left army Inaba Ichitetsu, the right army clan Bu Quan, Ando Mori, and Niwa Nagahide. It can be said that the entire main force of the Oda family was mobilized.

Tokugawa Ieyasu led the Tokugawa army to the left of the Oda army, supported by Sakai Tadaji and Ishikawa Shumasa.

On the other side of the sister river, Asai Nagamasa took the fierce general Isono Yuanmasa as the striker, and he played against the Oda army as the Chinese army. The Asakura Brigade was led by Asakura Keiken, and Asakura Keiki led the headquarters of the troops and horses to confront the Tokugawa Army.

This battle filial piety stool is a model for leading troops into battle from the side.

At the beginning of the battle, the forward of the Asai Army, Isono Yuanmasa, attacked the Oda Army fiercely, and the first to fourth teams of the Oda Army were defeated. When the situation was critical, Inaba Ichitetsu rushed from behind to launch a surprise attack on the right side of the main camp of the Asai Army, delaying the speed of the main attack of the Asai Army. Rescued the Oda Army from the crisis of the forward.

Later, because the Asai army was defeated by the Oda army, they were defeated.

At the same time, the Tokugawa army Kamihara Yasumasa also made a detour to the right side of the Asakura army and launched a surprise attack. Under the fierce attack of the Tokugawa army, the Asakura army was also defeated. In the first battle of Sister River, Asai and Asakura were defeated, and their vitality was greatly damaged, and they were no longer able to confront Oda Nobunaga.

In the end, the Asai and Asakura families were destroyed by Oda Nobunaga in turn.
