Just when the Iwaki family supported the Furukawa shogunate, the news of the destruction of the Yokose Yura clan also reached Oshu, which made Iwaki Shigetaka regret it. Although his adopted son, Iwaki Kintaka, has always opposed following the Furukawa Shogunate, Iwaki Shigetaka can only swallow this bitter fruit. Now that this step has been taken, there is no way to take it back.

On the one hand, the envoy of Shigetaka Iwaki also arrived at Sendai Castle, the new base of the Date family. Originally, the Date family's original base was supposed to be Yonezawa Castle. Due to the defeat of Yonezawa and the confiscation of the Dewa domain, Sendai Castle by the sea can only be used as a residence.

As a confidant of Date Harumune, Nakano Munetoki was very much in favor of uniting with the Iwaki family. Although it will damage the reputation of the Date family, it can only do so in order to regain the 15,000 stone territories such as Marumori Castle and Watari Castle from the Soma family.

As for Yonezawa Castle, Imaizumi Castle, Itaya Castle, and other 61,000 stone territories that were still in the hands of the Uesugi family, Date Harumun did not dare to move. With the current Date family, they don't have the strength to challenge at all, and the Date family can only fight with the Soma family, which is not strong, with the strength of 70,000 stones.

If Soma Moriyin hadn't been stained with the light of the Uesugi family, he wouldn't have been divided into places such as Marumori Castle and Watari Castle, and even so, the Soma family still only had a territory of 60,000 koku, and it was still difficult to fight the Date family alone.

On December 30, Date Harumuni finally made up his mind to do it. Watari Motomune was appointed as the general of the Soma family's strategy, the deputy general was Date Minoto, the military envoy was Makino Hisinaka, Koragawa Munehide, and the retainers and wealthy clans who stayed behind were Hyunmune (a major minister of the Date family), Ishikawa Harumitsu, Izumida Shigemitsu, Kunibun Moriken (Date family Ichi), Koragawa Morimune, and Shiraishi Sotori. The Date Army, reinforced by Yoshitaka Asaki, reinforced by Yoshitaka Aki, reinforced by Yoshitaka Kasaki, and 500 Kasai Army, reinforced by Kasai's cronies, made a total of 7,500 troops to Watari Castle.

If you want to say whether the Soma family is ready for war, Soma Shengyin is indeed ready. He had already built a small embankment city in the south of the city, and repaired the mountain card to the west of the city; Maruyama Castle, Kanayama Castle, and Kosai Castle to the east of Marumori Castle were all requisitioned, and defenses such as arrows were built, and Kakuda Castle (the former lord of the castle, Harimitsu Ishikawa, who was driven out by the Soma family) was repaired in the northern part of Maruyama Castle. On the other hand, Sakamoto Castle in the northeast of Marumori Castle was also headed by Horiuchi Konyin, a major minister of the Soma family.

It can be said that the area from Watari Castle to Maruyama Castle has been run by the Soma family as a defensive line, and as long as the retainers who are guarding it do not take it lightly and are betrayed, it is completely possible to keep the Date army out of the castle for several months. However, the retainers sent to the forefront by Soma Shengyin were a little spineless.

On the 31st, when the 7,500 Date Army was about to arrive at Watari Castle, Kii Fujihashi had already been rebelled by Makino Hichinaka. As soon as he saw the arrival of the Date army, Fujihashi Kii immediately opened the city gate and led his troops to join the Date army, and was willing to serve as the guide of the Date army.

The Soma family was not the only one who was betrayed by Fujihashi Kii. Naokiyo Kusano and Akiharu Aota, who had always been at odds with Soma Moriyin, directly raised troops in response to the arrival of the Date Army. Kusano Naokiyoshi also attacked and killed Nakamura Yoshibo, the lord of Nakamura Castle, and completely took Nakamura Castle for himself. Nakamura Shikibu also joined them after being persuaded by Naokiyo Kusano and Akiharu Aoda at Hitachikikan.

Due to the rebellion of Kuroki Castle, Nakamura Castle, and Hitachi Kikan, Horiuchi Konyin, who was still on the front line, was unable to contact Soma Moriyin in Kotaka Castle. Horiuchi Konyin is also isolated by the enemy on his back.

Not only that, but Ei Yinji and Okada Shigein also brought 1,000 reinforcements from the Soma family to assist Mori Takahiro and Akechi Mitsutada in Shimono Nasu County. Soma Shengyin has very few troops on hand that can be dispatched. Although Marumori Castle and Kosai Castle belong to the Soma family tree, the retainer Yoshinobu Sato and the father and son of Sato Nobunobu, they are already good at keeping their own castles, let alone making up for the gap in Watari Castle.

With the Date Army, under the leadership of Fujihashi Kii, they captured Kanoda Castle, Funaoka Castle, Kiyamaka, Kanayama Castle, Ryokawa Castle, Ono Castle, Otsumi Castle, and Maruyama Castle in one day. The important ministers of the Soma family, Changjiang Shengjing (the lord of Ono Castle), Izumi Yintaka (Liangchuan Castle), and Menma Keiqin (Kanayama Castle), were killed in battle, and Marumori Castle and Kosai Castle were surrounded.

Sakamoto Castle's Horiuchi Konyin led an army to rescue Sato Yoshinobu and his son, but was attacked by 2,000 troops left behind outside Kosai Castle. Three hundred of the 1,000 Soma were killed, and Horiuchi was taken.

Originally, the city could still support half a moon, but due to the death of a major minister, Horiuchi Konyin, the morale of the defenders was suddenly lost, and Sato surrendered for Shin out of the city. In order to reduce casualties, Watari Motomune did not let Sato be a seppuku and sent him to Marumori Castle to persuade Sato Yoshinobu to surrender.

The price offered by Watari Motomune and others was for them to continue to possess Marumori Castle and Kosai Castle, and from then on they became retainers of the Date family. For such a request, Sato Yoshinobu and his son could only agree in order to save the lives of the city soldiers.

The surrender of the Soma genealogy retainer Yoshinobu Sato and his son and the death of a major retainer Horiuchi Kinyin in battle lost all the 15,000 stone territories such as Watari Castle and Marumori Castle, which had been ceded to the Date family to the Soma family, within two days.

After learning of a series of defeats, Qingtian Tsuneshi could only surrender in Lingshou Castle to keep his territory. He also took the initiative to persuade the Date Army to surrender the Aota Tsunetaka of the clan, and Komagaling Castle, the last stronghold of the Soma family in the north of Nakamura Castle, no longer belonged to the Soma family.

Probably because the Soma family was defeated too quickly, Tao Qingxian couldn't believe his ears. Obviously, the defense line from Watari Castle to Marumori Castle was so impregnable that all the territory of 15,000 koku was captured by the Date Army in two days! This made the Uesugi army in various parts of Aizu have to immediately prepare for the battle against the Date family. In addition, Ei Yinji and Okada Shigein also led a thousand Soma troops to leave Shimono and go to Soma to rescue.

On the second day of the first month, Soma Shengyin asked Date Uemune, who was still in Kodaka Castle, before leaving the battle, and asked him if he wanted to return to Date at this moment. However, Date Zhimune's answer was that he resolutely did not go back, and also took Soma Shengyin's ten-year-old sister-in-law Soma Yoshiyin and second son Soma Takayin in advance. Date Uemune made his youngest and one of his daughters, who was about the same age as Soma Yoshiin, marry Yoshiyin Soma Yoshiin to be the main room.

The Soma family could only mobilize 2,000 troops due to insufficient troops to go out from Xiaogaocheng, and Soma Shengyin let Soma Yoshiyin stay behind, and he and Mizutani Yinsheng and Kihata Shengqing went out of battle. It may be that Soma Moriyin felt that the martial arts of the Soma family might end here, so after consulting with Mizutani Yinsheng and Kihata Morikiyo on the march, he ordered them to return to Kotaka Castle by all means even if they were killed in battle, and take Soma Yoshiyin, Soma Takayin (Soma Moriyin's second son) and Koshikawa Gozen to Aizu Wakamatsu Castle.

Mizutani Yinmori and Kihata Morikiyo can be said to have agreed with tears, as the genealogy of the Soma family, they don't want to see the Soma family's name cut off, and it's a pity that they can't die in battle with the lord as samurai. After Soma Shengyin arranged the aftermath, he encountered the army of Watari Motozong outside Mano Castle.

Although the Soma army was only 2,000, it was not afraid to face the 7,000 Date army. The Samurai of the Soma family were even more warlike, and under the leadership of Soma Moriyin, they once repelled the attack of the Date Army. However, after all, there was a big difference in the number of Soma troops and Date troops, and after a full-scale offensive launched by Watari Motomune, Soma Shengyin was killed in battle, and most of the 2,000 Soma troops were lost. When Mizutani Yinmori and Kihata Morikiyo learned that Soma Moriyin had died in battle, they immediately rushed back to Kodaka Castle with a dozen samurai on horseback.

At this moment, Eai Yinji also led a hundred horseback warriors to Kotaka Castle first, and he also learned of the death of the lord Soma Shengyin later. After Mizutani Yinsheng and Kihata Morikiyo informed Eai Yinji of Soma Moriyin's last wishes, the three of them immediately took Soma Yoshiyin, Soma Takayin, and Koshikawa Gozen in the castle away, and under the escort of one hundred and twenty Soma family horseback samurai, they did not choose to go to Uesugi Ryo first, but chose the bordering Tamura Ryo.

After receiving the report from Deura Shouqing, Tao Qingxian immediately informed Takahide Tamura to take over the Soma family, and he himself led 5,000 troops from Aizu, including Kawada Nagakin, Usami Seikatsu, Ashina Clan, Mori Takamasa, and Tao Nagafang, to Shiomatsu Castle. On the other hand, the Date family had become a rival daimyo, and Mori Takahiro also led his troops and horses out of Shimono under the notice of Katsuyama Yunkatsu. Although this is a helpless move, it can only be done in order to compete with the Date family. The Uesugi family didn't operate for long on the Shimono-Nasu-gun side, and there was not much loss if it was lost. For the loss of the wise family, the court will also be able to arrange them to the upper field, the lower general office, and other places.

Date Uemune has been reluctant to return to Date since the end of the Astronomical Rebellion, otherwise he would not have stayed in Soma Domain. This time, he wants to live and die with the Soma family, and as an Oshu probe appointed by the Muromachi shogunate, he will not live under the same roof with his sister-in-law, who has become a traitor. Date Uemune also knew that it was also a good thing for the Soma family to form an alliance with the Uesugi family, the governor of the Kanto region, and the Uesugi family had been loyal servants of the shogunate for generations to guard the Kanto region and other places. Date Uemune's marriage of his youngest daughter Koshikawa Gozen to Soma Yoshiyin is also for the sake of the Date family, once the Muromachi Shogunate wants to crusade against the Date family who is connected to the pseudo-shogunate, then the blood of the Date family can still be preserved through the Soma family, and it will not be completely severed.

In the first battle of Mano, a large number of samurai and retainers of the Soma family were killed. When Watari Motomune led his army to the foot of Kodaka Castle, he persuaded Date Zhimune to return to Date Motomune's house, but Date Zhimune refused on the grounds that he was not in the company of rebels. Seeing that there was no law to persuade Date to plant the city, Watari Motomune could only order the siege of the city. And there is not much resistance in the city, so only Soma Shengyin's side is close and the small surname is guarded in Honmaru. The Date army quickly occupied the Kulun of Sannomaru, Ninomaru, Nishinomaru, and Nishinomaru.

Date Uemune was seppuku at the age of seventy in Honmaru. Due to his advanced age, the seppuku was completed with the help of the small surname. Subsequently, after the main gate of Honmaru was breached, Soma Shengyin's family, small surname, and side were all spared. When the members of the Date family, such as Watari Motomune and Kunitive Moriken, quickly rushed to the residence of Honmaru Date Uemune in Kotakashiro, they found only the body of Date Uemune's body separated.

A few days later, all of the Soma Ryo were captured by the Date Army, and there was little resistance. Soma Yoshiyin and others were also transferred to Aizu Wakamatsu Castle under the reception of the Tamura family, and the Soma family was temporarily destroyed. Some of the wealthy families and retainers of the Date family were finally able to return to their old realms, such as Watari Motomune, Ishikawa Harumitsu, and Izumida Shigemitsu. The Date family annexed 60,000 koku of Soma Ling, which can be regarded as rising from 70,000 koku daimyo to 150,000 koku. Date Harumune only had the confidence to fight with the Uesugi family after swallowing the Soma collar, otherwise he would really not be sure to fight at all. As for what to do next, he still feels that he has to take it one step at a time.

In addition to the Uesugi family and the Iwaki family, the Soma family has a Tamura family. Tamura Takaken was originally the son-in-law of Date Uemune, and after the end of the Astronomical Rebellion, he became the main family of the Soma Kenyin (Sheng Yin's younger sister) of the Yingji sect, and the Tamura family and the Soma family still have a good relationship for now.

The Tamura family was the first line against the Date family, and Tamura Takaaki began to mobilize troops. There used to be a lot of hostile daimyo around the Tamura family, and they were surrounded by strong enemies, and they always had to rely on powerful daimyo to keep their name alive, so Tamura Ryo did a good job in terms of development. By the time of Tamura Takaxian's generation, the Tamura family had reached a territory of 33,000 koku.

After that, the Date Army did not return to its skills. The four men of Kushiri Sadacho (a group of people, the elder of the Date family), Sangori Socho (the son of Kushiri Sadacho), Endo Kinobu, and Ryokawa Sokiyo (Date Uemune Yatsuo) were the first to assemble in Sendai, and the army brought by these four people also had 4,000 people. Date Harumune planned to attack the Tamura family with the Date army led by Soma, and then he led his own team and the army of Sanori Sadacho and others to attack the Uesugi leader.

Date Harumune intends to go hand in hand, attacking from both sides. However, Tao Qingxian had already seen it. Tao Qingxian did not plan to divide his troops to deal with the Date army, he wanted Mori Takahiro to garrison the Suga River, and Kawada Nagajin to garrison Yonezawa and other places. As long as these places are held, then all that remains is the 10,000 people who defeated the Watari Motozong plus the Soma family.
