In the third year of Yonglu, on the twenty-fifth day of the ninth month. When Oda Nobunaga, who had already prepared to send troops to Kamiraku, heard that Takeda Shingen had sent Kiso Yoshimasa as the general to lead more than 5,000 troops of the generals of Minami Shinano, such as Ogasawara Nobury, Shimojo Nobuji, and Chihisa Yorimoto, to attack the pro-Oda family's Mikawa family Miyake Takasada, Miyake HD, Takahashi Nobumasa, Takahashi Masanobu and others, he immediately transferred his troops and led more than 20,000 troops into the Mizuno Domain, for fear that the Takeda army was a drunkard and did not want to drink.

Shortly after the Sagami Raid and the war that had lasted nearly three months and pacified the East Vietnamese Chinese, Cho Dinh had not had time to enjoy the long-lost tranquility, and Chang Lu received a battle report that made him angry.

According to the war report transmitted by Ota Shimasa, the head of the Oda family, the Oda clan, was ordered by Ashikaga Tomasa of the Horikoshi Principality to restore the old domain of the Furukawa Clan, and brazenly united with the Tagaya clan, Mizutani Clan, and other former Furukawa Princes to raise troops to rebel against the old ministers of the public, and has now invaded the Mabi, Shioya, Takatama, Kasama, Ishibashi and other places, and has led an army to harvest the crops such as rice and wheat in the villages in the enemy's territory (before the crops such as rice and wheat in the villages in the enemy's territory are harvested), and the people and cattle are invaded and plundered (invaded and plundered) the population, cattle, and There are thousands of horses. As a result, the realm (a place that becomes a battlefield when two or more forces fight against each other) is in an uproar, and the counties and towns are unable to resist each other, and they have been waiting for help.

It's really an internal worry, and the external trouble is rising again, and this Uesugi family is really never at peace.

After receiving the battle report, the court immediately ordered the lord of Zhuchuan Castle, Gomi Takashige, and the lord of Tsui Castle, Shinbata Chodun, to recruit 5,000 troops and enter Ota Castle, in order to prevent the Oda family from taking advantage of the situation to launch an invasion of Shimoso.

On October 1, shortly after Gomi Takashige and Shinbata Nagatsu Nyotsu led 5,000 troops into Shimosho Ota Castle, Oda led more than 500 troops to attack Sokunku after seizing the castle under the old command of the Tagaya family.

The court was furious, and immediately ordered the generals of the general office, the general general of the upper house, and the general of Anbo to quickly recruit troops in their respective territories to prepare for the crusade against the rebellious Oda clan. At the same time, the court also sent Saito Michizo, the lord of Usui Castle, to lead 5,000 troops to Hitachi Kawachi Prefecture, and joined forces with Katsuya Kasama, the lord of Tatsunozaki Castle, Takatama Shige, the lord of Edozaki Castle, Ishibashi Shinzo, the lord of Ushikujo Castle, the lord of Shimazaki Castle Yu Sasuko, and the lord of Kotaka Castle, Nishino Munekei, to strengthen the defense of Minami-Tokichi.

Although the court successively sent three important ministers to lead the army to garrison the gateway of the lower general country, he then thought about it carefully and realized that something was wrong. The Oda clan was surrounded on all sides by the domains of the Uesugi family's retainers, so how could he have rebelled without any chance of victory if it had not been provoked by powerful daimyo from outside?

Soon, the ninjas under the command of Kato Duanzo intercepted the messenger of the Takeda family and the Oda family at Kamisawa Katsuura, and the secret letter he was carrying was also sent to the hands of Asada.

After obtaining the secret letter, Asadachi dispelled the idea of mobilizing the troops of Shimono, Kamiso, Shizo, Anbo, Musashi, Iwaki and other places to concentrate superior forces and quickly destroy the Oda family. At the same time, the court ordered Kato Danzo to intensify espionage work in the Tokaido and Koshin areas.

Within two days, Kato Danzo informed the Asadachi of the news that the Takeda family was secretly recruiting troops in Suruga, Enoe, Izu and other places with the intention of seizing the country of Sagami. The Asagami generals immediately ordered the generals of the Sagami country, such as Zen Soji, Nagano Yosei, Ikeda Morishu, Okabe Motonobu, Asahina Taichao, Asahina Nobuji, Hirayama Mitsuyoshi, Okabe Tadahide, and Kaneko, to quickly recruit troops and prepare for the siege of the cage castle, and take strict precautions against the Takeda family. At the same time, in order not to let the Kanto prince Imagawa Shin make a mistake, Asadachi had to let the Imagawa clan leave Kamakura Tsuruoka Hachiman Palace to go to the Eagle Hunt outside Furukawa Castle.

On October 5, Takeda Shingen appointed Takeda Nobuyoshi as the commander-in-chief and led the armies of Enoe, Suruga, and Izu to attack Sagami in a big way, and the troops were directed at Ashigara Castle, an important town in Western Sagami. The lord of Ashigara Castle, Okabe Motonobu, decided to fight an ambush battle at Mt. Kintoki first, just to kill the prestige of the Takeda army.

Okabe Motoshrei carefully selected more than 1,000 troops from the forces of his brother Okabe and Asahina from the Okabe family and the Asahina family, and asked him to lead his army to set up an ambush on the path that the Takeda army must pass. Before his departure, Okabe Motonobu repeatedly warned him: "Do not attack the enemy's advance after entering the ambush, because your own team is close behind, and you will definitely not be able to resist it." Therefore, after letting the Takeda Army's vanguard leave the ambush place, and waiting until the army with Sun Tzu's 'Siru Army Flag' arrives, it will be the Takeda Army's main team. When the time comes, you can attack by surprise and you will be victorious. ”

Subsequently, in accordance with Okabe Motonobu's order, Minister Oka really caught the Takeda army off guard. The Takeda army was overwhelmed by the Okabe army, and Takeda Nobuyoshi believed that the Uesugi army in Sagami had already been on guard against the Takeda army, and in order to avoid the lone army being completely annihilated, he immediately ordered the entire army to retreat to Suruga Kato Prefecture. Okashitsuna was well aware of the enemy's outnumbered position, so he took it as soon as he saw it, and did not pursue the Takeda army, which was about to retreat to Surugagawa-gun, and returned to Ashigara Castle after building a kyokan at the foot of Mt. Kintoki, who had killed more than 300 Takeda troops.

After entering Fukasawa Castle, Takeda Nobuyhiro was furious when he learned that there were only more than 1,000 Uesugi troops who attacked his own team, and immediately said to the generals on the left and right: "The only powerful generals of the Uesugi family in Xiangshu are Okabe Tanba Mamoru, Asahina Suruga Mamoru and Asahina Bichumoru are only three people, so you should take care of them!" ”

Two days later, Takeda Nobushihiro and the Odawara Ise family gathered a total of more than 22,000 troops and marched into the territory of Ashigarami-gun. To everyone's surprise, this time the Takeda Army would be unusual, and the military discipline along the way was very strict, and there was no offense against the leader of the Uesugi Domain. After arriving at Ashigara Castle, Takeda Nobuyhiro did not order the siege of the castle, but personally led several samurai on horseback to the vicinity of the Otemon Gate and shouted to the castle soldiers at the head of the castle: "Since Okabe Tanba Moriden has summoned me with a secret letter, why don't you come out to greet the army of the Takeda family?" ”

After listening to Takeda Nobuyoshige's words, the defenders in Ashigara Castle had no idea what kind of medicine was being sold in Takeda Nobuyoshi's gourd, so they immediately reported to Okabe Motonobu, who was in charge of Honmaru.

And Okabe Motoshin only sneered twice after listening to the report of the city soldiers under his command, he knew very well that this was a counter-plot played by Takeda Nobushi, but Takeda Nobuyoshi played it poorly. Subsequently, Okabe Motonobu ordered the defenders in Ashigara Castle to hold out, and he wanted to see what other tricks Takeda Nobuyoshi could play.

After that, Takeda Nobuyoshi led the army to surround Ashigara Castle for a day and a night, and saw that Ashigara Castle was heavily guarded, apparently indifferent to his slightly somewhat pediatric strategy, Takeda Nobuyoshi was very disappointed by this, but he did not dare to immediately launch an attack on Ashigara Castle, so he had to order the whole army to withdraw from Ashigarami County, and turn to the area of Ozumi County and Taoaya County to continue to Karita in disarray.

As the saying goes, it is not rude to come and go, Takeda Nobushi sent an intimate greeting to Okabe Motoshi, and of course Okabe Motoshin must also express something to Takeda Nobushi.

On October 9, just as Takeda Nobushigeru led more than 22,000 troops into Osumi Prefecture, Okabe Motonobu again dispatched Okabe Motonobu to lead more than 1,000 troops to attack the Sagami Izu border, targeting Yamanaka Castle, an important town in Kita-Izu.

On the other hand, the defenders of Yamanaka Castle learned that an Uesugi division was intending to attack Yamanaka Castle after more than 1,000 troops of the Okashi Tsunabu crossed Hakoneka. Subsequently, Yonekura Shigetsugu (Yonekura Sotsugi), the lord of Yamanaka Castle, arranged for a family of relatives who remained in the castle to be guarded by Yonekura Nobutsu, Yonekura Toyotsugu, Yonekura Toyotsugu, Yonekura Dingji and others immediately led more than 500 city soldiers out of the city to meet the battle, and started an encounter with the Oka Minister Tsunabu. However, due to the inability to grasp accurate information and being outnumbered, Yonekura Nobutsugu and others were defeated and fled by Okahara Tsuna, and more than 300 Takeda troops were killed.

Okabutsuna immediately took advantage of the victory to pursue the attack, and in one fell swoop, he captured Yamanaka Castle, an important town in Kita-Izu, and burned all the grain and grass hoarded in the castle, but then retreated and returned to Ashigara Castle in triumph.

Takeda Nobushi never imagined at this moment that he was in full swing in Dazumi-gun, Taoaya-gun and other places Karita, but Okabe Motonobu took advantage of his unpreparedness to stab himself in the back, and also burned most of the grain and grass that Izu had mobilized in the country to attack Sagami.

Knowing that the defeat in the rear would inevitably lead to the fluctuation of the army's morale, Takeda Nobuyhiro had no choice but to stop the mess in Karita in Osumi and Taoaya, and led the army into Ashigarshita County, which was led by Odawara Ise, to rest.
