In the fourth year of Yonglu, April 20th. Takeda Shingen suffered a crushing defeat in the Hachimangawara area of Kawanakajima, and lost many important ministers such as Takeda Nobuyoshi, Baba Nobubo, Ichichi Shinryu, Takasaka Masanobu, Koyamada Toramitsu, and many other high-ranking lords (more than 100 cavalry for military service), symbolizing the decline of the Takeda family's rivers that dominated several countries such as Kai, Shinano, Suruga, Enoe, Izu, Hida, Higashimino, and Higashimikawa. Since then, Takeda Shingen has been closely monitoring the movements of the surrounding forces such as the Uesugi family and the Oda family in Shinano-Suwa Prefecture, and while reorganizing the castle soldiers under the command of Hara, who died in battle, he has been busy with the post-war disposition of the castle under the command of the former retainer who died in the war. However, due to the large number of retainers who died in battle, there was a shortage of human resources who could serve as city representatives, county representatives, and government officials, and the dilemma of uncertain successors. The Fourth Battle of Kawanakajima was also the third major defeat of Takeda Shingen since he came to power (the first was the Battle of Uedawara and the second was the Toishi Avarine). After losing the Fourth Battle of Kawanakajima, the Takeda family also suffered two major blows that made the future of the Takeda family even more precarious.

The first is the "two mountains" of the Takeda family, the Anayama family (a branch of the Takeda clan) and the Oyamada family (the guardian of the Tsuru clan and the secretary of the county), who successively raised troops in Hanoi and Tsuru in Jumo County to respond to the Uesugi family.

Originally, the Anayama family and the Oyamada family were allowed to run Minamijumo County and Toriru County on their own, and in addition to serving as generals of the first army in military affairs, they also served as ministers under the command of the Takeda family. Due to the strengthening of the power of the daimyo of the Takeda Shingen Warring States, the development of the Takeda family's domain, and the advancement of unified domination, the Anayama family and the Koyamada family were losing their independence in the Kawachi and Toru counties of Jumo-gun. Even though the Anayama and Koyamada families were able to endure the centralization of Takeda Shingen, they still could not endure the never-ending military service, servitude, and taxation.

In order to avoid the continuous infiltration of the Takeda family and break away from the control of the Takeda family, Anayama Nobujun and Koyamada Nobushige coincidentally rebelled against the cage castle in their own castles, and both quickly sent their retainers to Saijo Castle and Kogoe Castle respectively, hoping to get the support of the Uesugi family.

At present, although the Uesugi army won the Battle of Kawanakajima and expelled most of the Takeda family's forces from Takai-gun, Mizuuchi-gun, Geng-gun and Kanna gun, the generals under their command were heavily killed and wounded. Among them, Saito Asanobu was shot in the right eye by a stray arrow during the assault on the Takeda Gunden Army; Kakizaki Keike was wounded in the neck during the fighting; Katsunaga Sebe, a heavy minister of the Yohoku Dynasty, was seriously wounded in the battle with the Takeda Army and is now bedridden in Saijo Castle, and his son, Sebe Chief, has temporarily replaced his subordinates; The retainer of the Pesage Zojin Shoji Saemon died of his injuries; Powerful generals from Okushino, Echigo, and Noto, such as Shidamaki, Okawa Tadahide, Shoken Shosuke Yatsube, Noro Yazaemon, Takeuchi Genuchi, Inoue Higo Mamoru, Tojo Nobuhiro, Shibatsu Nobunobu, and Takanashi Gentoshi, were killed in battle at Hachimangahara and on the south bank of the Chikuma River······

In addition, there were more than 6,000 Takeda army captives, most of whom were from Kai and Shinano, and Koyama Asayaki suggested that the court should decide: "The former Uesugi has pulled out the land of the four counties of Kawanakajima, and most of the four county officials are not happy to return to Takeda for Uesugi." Takeda's soldiers repeatedly. If you don't kill them all, I'm afraid it will be chaos. ”

And the court did not take Koyama Asayuki's suggestion, he thought: "The world sees the head of the general of the Uesugi like a mountain, and the remains of the Uesugi are piled up into a mound, then the battle of the day after tomorrow, death should be a dead ear, who is willing to obey, who is willing to go down?" It is for the sake of being able to cut tens of thousands of lives and be suitable for the battle of strengthening the world, and to want to make a single achievement and be more firmly guarded by the princes, so the soldiers will then destroy their own momentum, and the army will win and lose its plan. What's more, the story of Takeda Shingen's successive deaths in Kita-Shinano due to atrocities such as slaughtering the city and killing and surrendering is a lesson from the past, and the court must not want to be frantically resisted by the people of Kai, Shinano and other places. Subsequently, Asadachi adopted the more compromise proposal of Usami Dingmi, which was to send all the more than 6,000 prisoners of war to Sado Island to dig gold mines on behalf of the local people.

After all, prisoners of war are not the same as ordinary people, these people are trained, and once someone takes the lead in resisting, a large number of people will inevitably respond. In order to prevent the more than 6,000 prisoners of war from mutiny, Asadachi and Kenshin decided to send 10,000 troops to escort the prisoners of war across the sea to Sado.

Since the court decided that the Uesugi army was not capable of destroying the Takeda family, which occupied the land of the Seven Kingdoms, in one fell swoop, he first recognized and blocked the territories of Anayama Nobujun and Koyamada Nobushige, and gave the Anayama family the freedom to cut off the land of the Kigaji Province and one county of Jumo County. As for the Oyamada family, the court also gave the land to cut off the capital of the Kai country.

Let the two of them and the Takeda family stage cannibalism

The curtain of the play, and at the same time set Takeda Shingen's backyard on fire, so that he couldn't care about each other. In this way, the Uesugi army was able to successfully capture the Azumi-gun, Ko-prefecture, and Saku prefectures of Kita-Shinano.

On April 21, Takeda Shingen, who was seated at Uehara Castle in Suwa Prefecture, learned that Nobuyoshi Anayama (Takeda Nobugen's son-in-law) and Nobushige Oyamada (whose mother was the sister of Takeda Nobutora and daughter of Takeda Nobutsu) had rebelled against him.

When Takeda Shingen intended to send 5,000 troops stationed at the junction of Kai and Suwa Prefecture to Irigasama, Yachidake, and other places to quell the rebellion, important ministers such as Mitsuken Nagasaka and Katsushi Kebe raised objections.

Nagasaka Mitsuken, Katsushi Kibe and others believed that once Takeda Shingen used this batch of troops to enter southern Kai to quell the rebellion, it would be difficult to ensure that the Uesugi army would not take this opportunity to attack Minami Shinano or even northern Kai in a big way, so these 5,000 troops could not go south.

Just when Takeda Shingen was worried, Nagasaka Mitsuken, Katsushi Kibe and others offered him a plan - forcibly conscripting the sons and grandsons of the generals who died in battle, the townspeople of the castle town, and the monks who became monks, but all men over the age of twelve or thirteen who could be requisitioned were recruited into the army, and they were incorporated into the army, and they could be reorganized into an army of tens of thousands within a month.

Takeda Shingen was very happy when he heard this, and immediately adopted the suggestions of Mitsuken Nagasaka, Katsushi Tracebe and others. However, Shingen Takeda did not realize that the decision he made would drag the Takeda family into an abyss from which they could never recover.

However, in the same month that Takeda Shingen was recruiting troops, Kenshin and Asadachi held a celebration banquet and rewarded meritorious soldiers in Saijo Castle in Okushinano. At the same time, the Asadachi also sent letters to the Asakura family, the Oda family, the Ando family, the Onodera family, the Tamura family, the Soma family, the current general of the Shoi, Ashikaga Yoshiaki, the Miyoshi family, and other forces, informing them that the Uesugi army defeated the 70,000 troops of the Takeda army in the battle of Kawanakajima, and killed more than 100 generals such as Takeda Nobushi, Takeda Nobuyo, Ichijo Nobuyyu, Baba Nobubo, Takasaka Masanobu, and Mokaku Torada, and the Takeda army was killed by more than 50,000 people, and Takeda Shingen fled into Kofu alone, and the Uesugi army took advantage of the victory to recapture Takai-gun, which was once occupied by the Takeda family. There are four counties in Kawanakajima, including Mizunai-gun, Geng-gun, and Hanna-gun. And the Takeda family is now displaced, the corpse is turned into the wilderness, the goods are bribed, the money is lost, the gods are angry and resentful, and the people are betrayed and leave······

Although some of the descriptions in the letter are exaggerated, the fact that the Uesugi army defeated the Takeda army in the Battle of Kawanakajima does not change. After confirming the victory of both sides, the Tamura family, the Soma family, the Ando family, the Onodea family, and other Ou daimyo (except for the southern family) sent envoys to congratulate Kenshin and Asada's victory over the invincible Takeda Shingen. The Asakura family, the Asai family, etc., did not send gifts, but only sent letters to congratulate the Uesugi family on their victory; Oda Nobunaga immediately sent a letter to the court after learning of the victory of the Uesugi army: "When the troops are sent south, Shinshu, Koshu, Junshu, Doushu, Enshu and other countries are all in the hands of the public, and the fame is endless. ”

Asada guessed Oda Nobunaga's careful thoughts, once he really immediately raised troops to the south to attack Shinano, Kai and other countries, then his Oda family would inevitably reap the benefits of the fisherman. After the Uesugi army and the Takeda army fought again in the Koshin area, the Oda family took this opportunity to send troops eastward to attack Higashimino and Mikawa, so that they could easily seize these areas. After that, Oda Nobunaga fabricated a reason to send troops to conquer the entire Gyeonggi region after destroying the Asai family that had seized Kita Omi and the Asakura family that had divided Waksa and Echizen. The Uesugi family will also lose a lot of losses in the battle with the Takeda family, so they will not be able to attack the Gyeonggi side in a short period of time.

At this time, Takeda Shingen fell ill after the attack of war wounds in the Uehara Castle Honmaru and the deterioration of tuberculosis, esophageal cancer, stomach cancer, etc., and after returning to Kofu, he died and a generation of famous generals died at the age of forty-four.
