In addition to the Nagano family, the most powerful samurai family in the Tone River basin in the central and northern part of Ueno country are the two Nagao families of the Shirai Headquarters.
The Shirai Headquarters was originally two families. This Nagao family had controlled the Yamauchi Uesugi clan for a long time, and its power temporarily surpassed that of the Nagao clan, the Ashikaga Castle Nagao family.
Unfortunately, there were many wars in Kanto, and the power of the two families was greatly reduced. In the end, even the identity of the head of the Yamauchi Uesugi family was taken back by the Nagao family of Ashikaga Castle.
It was not until the defeat of Uesugi Kensei and the destruction of the Yamauchi-Uesugi family that the internal struggle between the three Nagaos for the head of the Yamauchi-Uesugi family came to an end.
At this time, the two Nagao families of the Shirai Headquarters, although their decline was not as good as before, still controlled their core territories, Shirai Castle and Sosha Castle.
After the Azuma River and Tone River meet in the southern part of Mount Komochi, they flow southward. Shirai Castle is on the north bank of the intersection.
The Tone River continues to flow south, reaching Sosha Castle in the middle of Ueno, and further south to reach Umbashi Castle.
The Tone River will then join the Karasugawa River in the southern part of Ueno, turn southeast and flow out of Ueno Province. After joining the Arakawa River, it will go straight down to Edo and out to the sea, becoming the dividing line between Musashi Province and Shimotsou Province.
For Terutora Uesugi, Mount Haruna, Mount Shimochi, and Mount Akagi in the north of Ueno, as well as the Tone River and its tributaries between the three mountains, were his main rear area as he headed south, and he could not afford to lose it.
The mountains are powerful in attack and defense, the rivers are smooth in transportation, the two long tails, and the two Naganos are the powerful local warriors she has been wooing.
Sanada Nobushige took over Agatsuma County and destroyed the Saito family in Iwaki Castle. Her method of eradicating the roots was too violent and would seriously damage the trust of the four Ueno forces in Uesugi Teruhora.
Although the Nagano family of Minawa Castle is an ally of Terutora Uesugi, the Nagano family of Umebashi Castle is helping the Hojo family. Her family secretly assists the Numata retainers group in overthrowing Numata Kenyasu's rule, and their attitude is ambiguous.
The Obata family of Kunmine Castle, which controls the southern part of Nishi Ueno, and is an in-law of the Nagano family of Minawa Castle, is actively persuading Nagano Yamasa to remain neutral.
In order to win over Nagano Yasumasa, Uesugi Teruhora has promised a lot of benefits, and Nagano Yasumasa has also made it clear that he will side with Uesugi Teruhu.
At this time, the Saito family of Iwaki Castle was killed, and the Shirai Nagao family already felt a direct threat from the direction of Azuma County.
This kind of thing will happen especially when the two Nagao families of Shirai Headquarters clearly support the Echigo side.
How could Uesugi Teruhora guarantee that Sanada Nobushige would not attack again? How could the Shirai Nagao family believe it?
The northern part of Mount Haruna has changed hands, and Nagano Yasumasa in the southern part can trust Terutora Uesugi, but is she willing to trust Yoshigan Shiba's Kanto Agency?
Sanada Nobushige was Shiba Yoshigan's dog, and he was not Uesugi Teruatora's dog. Even if Uesugi Teruatora wanted to reassure them, he would feel scared.
What if Sanada Nobunari is so greedy for profit that he gets addicted to stealing from the city and attacks the Shirai Nagao family?
Teruhora Uesugi became angrier as he thought about it. He glanced at Yoshigan Shiba next to him and said angrily.
"What a restless little girl!"
Teruhora Uesugi was cursing, but Yoshigan Shiba hid his excitement and silently gave Nobushige Sanada a thumbs up.
When the Kawanakajima war was negotiated, he took advantage of Sanada Nobunaga's life-saving grace and gave her super high treatment in return, hoping that one day she could be of use to the Shino clan.
The Kanto Imperial Palace established by Shiba Yoshigan is an extremely embarrassing existence. It is an organization that claims to lead the imperial family in Kanto, but there is no imperial family in the core area of Kanto and the eight states of Kanto in the narrow sense.
In other words, he has no influence on the Kanto Plain, the land of the eight states. The so-called Kanto Shisho mainly consists of the Nakagoshi Etsu fringe samurai families in Echigo who were excluded by the Uesugi retainers.
If there is a fig leaf, it is Ogasawara Nagatoki of Hokushin, who is considered a descendant of the declining Shinano family.
In order to gain a foothold in the Kanto Plain, Shiba Yoshigan showed great favor to Sanada Nobunige and protected him in every possible way. There were also doubts within the Kanto Palace.
This time, Sanada Nobushige borrowed the power of the Shino clan in Nishi Ueno to occupy Iwaki Castle and capture Azuma County, which really helped him gain face.
Sanada Nobushige is stuck in the northwest corner of Ueno. How much stone height can be obtained is small.
The pressure she put on the Numata family, the Shirai Nagao family, and the Minawa Nagano family gave Yoshigashi Shiba the confidence to speak to the Ueno samurai family, which was a great strategic gain.
Yoshigan Shiba needs a fulcrum to leverage the entire Kanto Plain. The Kanto Palace is his crowbar, and Sanada Nobushige is his fulcrum.
Terutora Uesugi was unhappy because she was used to being arrogant and dictatorial and could not tolerate disobedience from others, thus destroying his military strategy.
Although Kanto Strategy is a collaboration between Uesugi and Shiba, Uesugi Teruhora has always been in a dominant position, because Yoshihiro Shiba has a shallow foundation in Kanto and does not have the confidence to say no.
Although the truth is embarrassing, in fact, Yoshigan Shiba's influence on Teruhora Uesugi mainly lies in the temptation of beauty.
If it weren't for Uesugi Teru's lust that made him faint and spend a lot of money chasing men. Given the strength of both parties in Kanto, this cooperation would actually be very unbalanced.
The mere Hokurikudo trade route was by no means important enough to make Yoshigan Shiba and Terutora Uesugi, the great daimyo of Echigo, equal in importance in the Kanto strategy.
The land soldiers belong to Uesugi Teruhu, and the network with the Kanto samurai family also belongs to Uesugi Teruhu. The food, soldiers, and people needed for the war are all provided by Uesugi Teruhu. Shiba Yoshigan provides some money, which is considered p.
But now, with the stability of the Kanto Palace and Sanada Nobushige's successful attack on Azuma County, Uesugi Teruhora has subconsciously felt uneasy.
In response to this, Shiba Yoshigan said, you are still here! Of course he wants to kill this useful chess piece of Sanada Nobuyoshi to expand his influence.
"Although Sanada Nobushige is reckless, being able to capture Azuma County will still be beneficial to the Kanto strategy."
Shiba Yoshigami was critical of this matter, Uesugi Teruhu glanced at him and hummed.
"The location of Iwaki Castle is too important. It is the sharp knife behind Shirai Castle and Numata Castle, which can easily cause unrest among the local samurai.
Even Nagano Yamasa of Minawa Castle will be afraid of Sanada Nobushige, which is not conducive to my strategy of recruiting them to form a coalition.
The army is about to move south, and all parties are already willing to take refuge. If they stop and hesitate because of Sanada Nobunshige's reckless move, wouldn't it be a big mistake and a small mistake?
I don’t think it’s worth it for a remote place like Azuma County to affect our plan to unite the Ueno samurai family.”
Shiba Yiyin retorted.
"The Kanto Plain has been war-torn for hundreds of years, and all the Ueno people in Ueno are retainers of Uesugi Yamauchi.
I dare to ask His Highness Uesugi, when have these people ever thought about fulfilling their duties to their lord? Does uniting them have more advantages than disadvantages, or does the disadvantages outweigh the advantages?
I do agree with Hojo Ujiyasu's approach. These people should be eliminated through territorial nationalization in order to restore peace to the Kanto Plain.
If we confront the Hojo family and start a tug-of-war, they will definitely play the trick of changing the King's flag on top of the city wall.
These people have long forgotten the loyalty of the Wu family and can only use them without having too many illusions."
