In the third year of Yonglu, May 10. Just when the court did not have enough troops to stop the southern Harimasa's southward invasion and was unable to do anything, the envoy Morioka Nobumoto, sent by the southern retainer Oura Nobu, came to Aizu Wakamatsu Castle with gifts to ask for an audience.

"My lord, this person will definitely be able to completely contain the southern family in the future, so that it will not be able to send troops south. As long as the Oura family can suppress all of Tsugaru County, then the blow to the southern family will be huge. Yamazaki Hidesen reminded Asada. Originally, Asadachi did not plan to meet with Morioka Nobumoto, because he felt that it would not be of much use to him for a small wealthy clan to raise troops in Tsugaru County to rebel against the southern family.

"The Daura family has no more than a thousand soldiers, how can they attack the land of Tsugaru County? The southern family assigned retainers to stay in the important towns of Tsugaru County, such as Dakouji Castle, Ishikawa Castle, and Yokonachi Castle, not to mention that the strength of the powerful lords in Tsugaru County, the Daikoji family and the Nanaoka Kitabatake family, was not inferior to the Oura family. The national lords in Tsugaru County, such as Toki, Shimodate, Shimone-hang, Saruga, Waihama, Rui, Sawari, and Takimoto, are all from Ishikawa and Nanbo, so how easy is it for the Oura family to successfully conquer Tsugaru County? "Asadachi did not think that the Oura family would be able to capture Tsugaru Prefecture and occupy it.

"Only let the Anton family send troops to assist the Oura family in raising troops, and then add the support of the family's food, grass, ordnance and other materials. In this way, the Oura family will be able to gain a foothold in the Tsugaru area after raising troops to rebel against the southern family. "Yamazaki Hidesen wanted to use Oura to raise troops in Tsugaru County to contain the southward movement of the southern Harimasa.

"That's all there is to it." Chaoding can't think of a better way at the moment, so he can only have the attitude of giving it a try first.

Subsequently, Asada secretly met with Morioka Nobumoto, a retainer of the Oura family, and accepted the three eagles that Oura had offered for the letter. After that, Asadachi asked Morioka Nobumoto to go to the three counties of Dehanaso, and asked him to go to Tsugaru County with Sakata Haoshang, one of the Sakata Thirty-six Parties, Nagata Kanjuro and others, with the supplies that Asadaku supported the Oura family, and asked Morioka Nobumoto to warn Oura not to act rashly at the moment, and wait for the best time to raise troops to respond to the Uesugi family. This time, the DPRK provided Shin with 500 spears, 150 bows, and 30 iron cannons, and transported them by sea to the samurai near Tanesato.

In order to prevent as much as possible from inciting the Uesugi clan to incite the Uesugi clan to revolt against the people of the country, such as the Tsulesawa-gun, Enosa-gun, Barnyard County, and Waga County, the court and the shogunate wanted to use the hands of the imperial court and the shogunate to weaken and reduce the influence of the indigenous daimyo who had been entrenched in the two countries for hundreds of years. The solution that the court came up with was to divide the country of Mutsu into Mitsu Province (under the jurisdiction of Tsugaru-gun, Kita-gun, Minohe-gun, Ninohe County), Rikuzen Province (under the jurisdiction of Natori-gun, Miyagi-gun, Kurokawa-gun, Kami-gun, Shibata-gun, Tota-gun, Shida-gun, Oshika-gun, Momo-gun, Kurihara-gun, Nobuye-gun, Tamazo-gun, Motoyoshi-gun, Kisen-gun), Lu Chugoku (under the jurisdiction of Iwate-gun, Shiba-gun, barnyard gun, Waga-gun, Suki-gun, Kunohe gun, Iwai-gun, Garizawa-gun, Ethorn-gun, and Antago-gun), Iwashiro Province (under the jurisdiction of Aizu-gun, Adachi-gun, Azuki-gun, Iwase-gun, Onuma-gun, Kawanuma-gun, Nobuo-gun, Date-gun, Yama-gun), Iwaki Province (Igo-gun, Ishikawa-gun, Iwa-gun, Iwa-gun, Iwa-gun, Panmae-gun, Uta-gun, Karida-gun, Kikuta-gun, Shirakawa-gun, Shirakawa-gun, Shiba-gun, Shiba-gun, Naraha-gun, Tamura-gun, Gyukata-gun, Watari-gun) are five countries. The court also went to the shogunate and the imperial court together with Kenshin, hoping that the shogunate and the imperial court would agree and set up relevant official positions and military positions.

Kenshin stayed at Aizu-Wakamatsu Castle for some time and left on May 15 to return to Echigo Prefecture. At the same time, the court summoned Mori Keihiro to Wakamatsu Castle and asked him why he had sent troops without reporting on many occasions before. Mori Keihiro did not defend himself after knowing that he was wrong, and the court later dismissed Mori Keihiro from his position as the head of the Mutsu Flag and placed him under house arrest in Chomeiji Temple outside Aizu Wakamatsu Castle for reflection.

As for the territory of Mori Keihiro, it was managed by his uncles Mori Takamasa and Mori Takatsu, and the position of Mutsunoku flag head was succeeded by Kawada Nagajin (Mori Keihiro's brother-in-law), so that he could command the Chutsu generals such as Taira Shige, Tantsunashige, Kiuchi Yinshi, Matsudo Yinyori, Asari Norisuke, Kankawae Mitsutoshi, Kankawae Hirotoshi, Mori Takamasa, Mori Takacho, Saito Toshiji, and other Chutsu generals. At the same time, the court transferred 10,000 koku from his Lingitaya, Shikubu, Funasaka, and Sekine to Shinhori Castle, Terabayashi Castle, and Hondate Castle (18 Castles, formerly the original barnyard Kan family) and other places in Mutsu Barnyard Gun. In addition, in order to allow Kawada Nagato to better command the Nakatsu Oku generals to resist the southward invasion of the southern family and the attack on the Tono Asonuma family, Kawada Nagajin inherited the family name of the Uesugi family in the declining Sagami Mansion and allowed him to use the bamboo finch pattern.

Previously, due to the refusal to send troops to assist Koyama Asakiyuki in pacifying Hitachi, Taira Shiga, Dan Tsunashige, Kiuchi Yinshibu, Matsudo Yinyori and other bannermen under the command of the Asada, they did not dare to treat Kawada Nagajin as a Huangkou child and looked down on him, and they successively sent letters to Kawada Nagato to congratulate him on succeeding to the head of the Mutsu flag and inheriting the family name of the Uesugi family in the house, and also hoped that Kawada Nagaqin could give them the opportunity to make meritorious contributions, so that they could regain the identity of the Osei Banner.

On May 30, more than 200 members of the Kawada clan, including his father Motoko Kawada, his younger brother Tadashikin, his uncle Shigekin, and his brother Masako Kawada (son of Shigekin Kawada), entered the new territory of Honkan Castle. On the one hand, he has to resist the southward invasion of the southern Harimasa, and ensure that the barnyard gun, Waga and other places are not invaded by the southern army; On the other hand, Uesugi Naga also had to organize troops to invade the Azenuma family, which occupied Tono Jushigo in Suii County, so that the pressure on Asari Noriyu, who was sticking to the castle in Tiansuo, was relieved.

At the same time, after receiving Kenshin's letter, Nanbu Harumasa didn't want to really tear up his face with the Uesugi family, so he asked Ishikawa Takan, Kunohe Masashi and others to suspend the attack on Takasui Temple Castle, the home of the Takamizu Temple Spo family, and the Great Xuanseikan and Sabi Inner Hall, which were still unwilling to follow the southern family, and Nanbu Harumasa sent acting officials to the previously captured Seniwa, Takada Castle, Spo Castle, Tokutan Castle, Nagaoka Castle, Iiooka Castle, Tamayama Castle, Ishishimizu Castle, Inogokan, Shizukuishikan and other places to enter the inspection and castle to invite the general. It intends to occupy the southern part of Iwate Prefecture and the northern part of Spo Prefecture for a long time.

After learning that Nanbu Harumasa had seized the territory of the Takasuji Spo family, he could only acquiesce for the time being, because he was now preparing to return to Kawagoe Castle first to preside over the counterattack against Tokaido and the transfer of the retainers of the Ueno country.

At the same time, generals such as Ota Shimasa, Yamamoto Temple Nacho, Miyagi Masayu, Nagano Yoshimori, Masaki Michitoshi, Masaki Tokimori, Kano Hideharu, Anazawa Toshimitsu, and Ikeda Morishu led more than 18,000 troops confronted the more than 10,000 Takeda troops led by Takeda Katsuyori and Yamamoto Kansuke at the Sagami River.

After a period of tug-of-war with Takeda Katsuyori, Yamamoto Kansuke, Nagano Yoshimori, Hideharu Kano, and Michitoshi Masaki with Takeda Katsuyori, Yamamoto Kansuke and others, Ota Shimasa decided to take the initiative again.

On 10 May, more than 10,000 Takeda troops led by Takeda Katsuyori, Yamamoto Kansuke and others engaged in a battle with Nagano Yosmori, Michitoshi Masaki, and Ikeda Morishu among the Uesugi army, defeating the Uesugi army and capturing more than 300 heads. On the 20th, Hideji Kano, Toshimitsu Anazawa, and Tokimori led more than 5,000 troops in the Uesugi army to engage more than 4,000 troops led by Yonekura Shigetsuri, Imafuku Yukiyo, Iwate Nobumori, and Aonuma Tadaki, but they were also defeated and retreated.

On the 25th, more than 3,000 Uesugi troops led by Kibe Fan Tora and Miyagi Masayi led more than 3,000 Uesugi troops to attack and break through the Oishi Seaki, Oishi Nobuki, Oishi Terumonaka, and Oishi Dingken who had crossed the Sagami River. Because the large battalions established by the Takeda Army's Oishi Dingji, Oishi Nobuki, Oishi Terumonaka, and Oishi Dingxian were burned down by the Uesugi army, the Takeda army withdrew to the west bank of the Sagami River after repelling the Uesugi army.

During the period when Asadai left Koe Castle for Aizu Wakamatsu Castle, generals such as Ota Shimasa, Yamamoto Temple Dingcho, Kano Hideharu, and Miyagi Masayu led their troops to fight more than ten times with Takeda Katsuyori, Yamamoto Kansuke and other generals of the Takeda family, and each other won and lost.
