In the third year of Yonglu, on the thirtieth day of the fifth month. When Asakuki Koyama destroyed half of Kai's economy, Shingen Takeda had to negotiate an armistice with the Uesugi family. The shogunate envoy invited by the Takeda family was the former governor of the Takeda family, Takeda Shintora. And Takeda Shintora did not come to Sunfu Castle alone (never entered Kai for life), but also entered Sunfu Castle with the last daughter Kikuhime.

Originally, Takeda Nobuta planned to marry the last daughter Kikuhime to Imadegawa Harumi (the son of the left minister Imadegawa Kimihiko and Kikutei Haruki), who was the secretary of the three at the time, but after learning of the continuous defeats in the war between the Takeda family and the Uesugi family, Takeda Nobuta temporarily gave up the idea of marrying the Imadegawa family.

At the same time, Takeda Katsuyori fought well in the Sagami River area, which was in stark contrast to Takeda Shingen's own army, which had nothing to gain.

On 5 June, Uesugi generals such as Shimasa Ota, Sadada-ji Nadanaga, and Hideharu Kano, who were still determined to annihilate Takeda's Katsuyobu, attacked the Takeda Army's main camp in Sukawara with the generals of Nagano Yoshimori, Ikeda Morishu, Masaki Michitoshi, and Masaki Tokimori. When Takeda Katsuyori learned of the Uesugi army's attack, he quickly ordered more than 500 Takeda troops under his command, including Yamanoi Genzo, Iwashita Sorokuro, and Yakubukuro Kosuke, to ambush in the deep forests around Sukahara, waiting for his own signal to attack the Uesugi army. When the advance of the Uesugi army marched to the place where the Takeda army's main camp was less than a stone's throw away, Takeda Katsuyori immediately waved the match and ordered the ambush army to shoot arrows at it, and then the generals of the Takeda army's main camp, such as Yonekura Shigetsugu, Ifuku Yukiyoshi, Iwate Nobumori, and Aonuma Tadayoshi, led the army to stand out from it and attack the Uesugi army in the front. As a result, this time, Uesugi generals such as Ota Shimasa, Yamamoto Temple Dingna, and Kano Hideji were defeated by Takeda Katsuyori again, and the vanguard of the Uesugi army was beheaded by the Takeda army by more than 200 ranks, and they left in embarrassment.

Uesugi generals such as Ota Shimasa, Yamamoto Temple Dingna, Kano Hideharu, and Nagano Yoshimori fought more than 30 battles with the Takeda Army, and they still lost more than 5,000 casualties despite the superiority of troops and geographical advantages, and the casualties reached nearly 5,000, while the Takeda Army suffered less than 2,000 casualties. Now that the morale of the Uesugi army has almost fallen to the bottom, Asadachi has no choice but to exclaim: 'Takeda Shiro, who is deeply convinced of Genshin Shinden, is a terrible enemy'.

Just when the Uesugi army on the east bank of the Sagami River was at a loss, Takeda Katsuyori, Yamamoto Kansuke and others led the army to retreat on their own initiative. This made Ota Shimasa, Yamamoto Temple Tosunaga, Kano Hideji and others suspect fraud, and continue to stay on the east bank of the Sagami River for two full days.

Then, with Hosaku's report, Ota Shimasa, Yamamoto Temple Dingcho, Kano Hideji and others led their troops across the Sagami River to quickly relieve the siege of Zen Soji, Okabe Motonobu and others, who had been trapped in the lonely city for more than two months.

Because Koyama Asakyuki led the army to break through the defense line of the people of the northern country of Jiafei such as Wuchuan Zhong and Jinjin Zhong one after another, it was like a no-man's land in Jiafei. The wealthy clans and people of the Takeda family in various parts of the country were shocked. At this time, Takeda Shingen was forced to withdraw the victorious Takeda Katsuyori and other troops to the Suruga Kato area and Izu, and temporarily abandoned the invasion of Sagami Province.

However, after losing the powerful foreign support of the Takeda family, the Odawara Ise family successively lost the castles they had previously captured in Ashigarami-gun, Osumi-gun, and Taoaya-gun, and had to stick to the few castles in Ashigara Castle, such as Odawara Castle and Yusaka Castle, Goshoyama Castle, Takagesuyama Castle, and Jinshi Castle.

On the other hand, Uesugi generals such as Ota Shimasa, Yamamoto Temple Dingcho, and Kano Hideharu took advantage of the retreat of Takeda Katsuyori, Yamamoto Kansuke and others to Suruga and Izu and quickly marched forward, and captured 16 castles previously occupied by the Odawara Ise family, including Imaizumi Castle, Karino Castle, Kaneme Castle, Aimei Castle, and Donbara Castle, and won many Odawara Ise retainers such as Yamaguchi Echigomori, Okawa Hyogo, Shimizu Echizen Mori, Yamakaku Jibu Daisuke, Yamamoto Shinanomori, and Kushima Iga Mamoru in one day and one night. The Odawara Ise family lost all of their territories in Ashigarami-gun, Osumi-gun, and Taoaya-gun in a short period of time, and most of Sagami Province returned to the Uesugi family.

Okabe Motonobu, who had previously held on to Ashigara Castle for more than two months, saw that the Odawara Ise family was defeated, and immediately led an army of more than 500 to capture nine castles, including Shinjo, Yuzawa Castle, Nakagawa Castle, Matsuda Castle, Iwahara Castle, and Dojoyama Castle, and captured more than 300 members of the Odawara Ise Army.

On June 10, Shimasa Ota, Yamamoto Temple Nacho, Kano Hideharu, and Okabe Motonobu will no longer dwell on the difficult Odawara Castle, but will continue to march to Ashigara Gun. Sensing the movement of the Uesugi army, Takashi Ise immediately ordered his retainers Murata Kubei, Koseki Kabei, Yamanaka Daikaisuke and others to lead more than 1,500 troops out of the castle to confront the Uesugi army in Mt. Kintoki, Mount Kamiyama and other places. The two armies fought fiercely in Takasakiyama Castle and Jinshi Castle, and finally Murata Kubei, Koseki Kabei, Yamanaka Daikisuke and others were outnumbered and were captured by the Uesugi army, and more than 1,500 Odawara Ise troops were completely wiped out. Ota Shimasa, Yamamoto Temple Dingcho, Kano Hideharu and others will take advantage of this wave of victory, and then successively engage the Odawara Ise army in Yusaka Castle, Goshoyama Castle, Tamine Castle and other places, and have achieved certain results. If this momentum continues, it seems that it is only a matter of time before the entire country of Sagami is about to return to the hands of the Uesugi family. However, at this time, under the planning of the scheming Takeda Shingen, Takeda Nobutora, the envoy of Ashikaga Yoshiteru, the general of Seiyi, issued an armistice order to Asadawa Kenshin, urging the Uesugi family and the Takeda family to start peace talks, and to recognize the identity of the Daimyo of the Ise clan and the fact that he had a territory of more than 30,000 koku in the first county of Ashigo-gun.

Originally, the court decided not to pay attention to Ashikaga Yoshiteru's armistice, and wanted to destroy the Odawara Ise family in one go. However, when Kenshin sent his retainers Minori Honjo and Naoe Keitsuna to Kawagoe Castle, he also urged the Asada to accept the shogunate's armistice order, which forced the Asadachi to accept the shogunate's armistice order. Eventually, the court was forced to negotiate peace with the inconsequence of recovering the entire territory of Sagami Kingdom, and in a fit of rage, he began to ignore political affairs for the time being, and focused on changing the city. On the basis of the original Edo Castle, the Imperial Court planned to renovate Edo Castle on a large scale, and planned an additional 5.5 kilometers of open space from east to west and 4 kilometers from north to south on the periphery of Edo Castle for expansion.

In order to reduce the Uesugi family's expenses on the general invitation and to test the loyalty of the daimyo of the eastern province, who had already submitted to the Uesugi family's military gate, the court issued a 'general request to the entire eastern country' and issued an order to the daimyo of the two countries to assist in the construction of the castle. Subsequently, the daimyo of the two countries, such as the Tamura family, the Soma family, the Tozawa family, and the Anto family, contributed money and efforts to show their loyalty to the Asada. Although many of the daimyo of their subsidiaries contributed money and efforts to Edo Castle, Shinagawa Minato, Edominato, and other places, there were still people who took a negative attitude towards the general service - Onodera Keido. After receiving instructions from Edo Castle, Shinagawa Minato, Edominato, and other places, Onodera Keido had a relatively negative attitude towards the general request, and his family governor, Onodera Keimichi, ignored it on the grounds of illness. On the contrary, the Onodera family's national lords, the Oi family and the Salmon Nobu family, were very concerned about this general invitation, and repeatedly sent letters to Hirosawa Tadanobu, Soga Yushige, Nambada Hiroyoshi, Miyagi Masayi and other important ministers under the command of the court, hoping that they would be able to participate in the general invitation to Edo Castle, Shinagawa Minato, Edominato and other places.

This greatly reduced the court's favor for the Onodera family, and he intended to 'cut the feudal domain' of the Onodera family after the completion of the general invitation in Edo Castle, Shinagawa Minato, Edominato, and other places.

On the other hand, Ota Shimasa, who deeply blamed himself for his incompetence, decided to shave his hair and escape into the empty door, and the Dharma name was "Daoyu (Sanrakusai Entering Daoyu)". And important ministers such as Yamamoto Temple Dingchang and Kano Hideji also returned to the city to take the initiative to think about it behind closed doors, and also wrote to the court in the hope of reducing part of the Zhixing land.

On June 15, the court ordered his retainers Hirosawa Tadanobu, Soga Yushige, Nambada Hiroyoshi, and Miyagi Masayo to lead an army to dismantle the unnecessary fortresses located in Ashigarashi-gun and Ashigarami-gun, and transport large quantities of wood, stones, and other materials to Edo Castle. The Asadachi intends to expand Shinagawa Minato (called Minato on the sea and Minato on land) in the south of Edo Castle and Edo Minato in Asakusa.

And the Iseshi Takashi in Odawara Castle can only watch the Uesugi army dismantle the castle soldiers around Odawara Castle one after another, because he is now unable to take the initiative to fight against the Uesugi army, and a large number of powerful countryman lords and retainers under his command were killed in the war with the Uesugi family, and the Takeda family has now withdrawn nearly 10,000 troops to Suruga and Izu, resulting in the Odawara Ise family being isolated and helpless, and can only temporarily trap the lonely city.
