On July 10 of the first year of Eiroku, the entire territory of Shimono Ichikoku was occupied by the Uesugi army. At the same time, Kenji Namba also led 8,000 Kamishu soldiers to invade Kai Province under the guidance of the Takejaku Guard led by Kanzo Kato. The Kamisu soldiers each carried only three days' worth of dry rations, and marched from Tokura Castle in Musashi-Tama Prefecture in a hurry.

Their first stop was the three-headed mountain between Musashi and Kai. To the southeast of Santou Mountain was the domain of Kato Toraki, a retainer of the Takeda family. During the reign of Takeda Nobuto, Kato Toraki was the Takeda family's flag samurai and Takeda Shintora's side, and also served as Takeda Harunobu's bow guide. Although his territory is a relatively poor part of the country of Jiafei, there are still more than 10,000 stones. Because his sons Kato Nobukuni and Kato Keitaka both led the army to Shinano with Takeda Shingen, there were only 15 samurai in the territory and 200 ashigaru garrisons in various places.

Although on the surface, it seems that the Kato family is still capable of holding the castle and holding off the Uesugi army for a while. However, the main force of 200 ashigaru is scattered all over the place, and the checkpoint stationed at the junction of Kai and Musashi, Kabuka, has 100 ashigaru garrison.

As the name suggests, the Kabuka is the gateway from Kai Province to Musashi Province. This place connects the roads that lead to the Oyamada and Kato necks, respectively.

Nobushige Oyamada is currently the largest lord in Kai Prefecture (Tsuru County), and he is also a member of the Takeda family and the lord of Iwaden Mountain Castle. He still needed to return to Shinshuka after receiving Sano Nobutsuna and his party, because none of the 10,000 Takeda troops under his command had yet entered Kai Province, and more troops were still marching in Shinano.

The Takeda Army, which has returned to help, has not yet arrived, which makes Namba Kenji feel that it is a great opportunity. When Katsunuma Nobumoto delivered the news that the garrisons of Kato, Oyamada, and Yatsukawa were empty, Namba Kenji and Kato Danzo immediately took action.

In just one day, Kato Danzo ordered the ninjas affiliated to Takejaku to open the gates of Kobuka, and after several Ashigaru longhouses set fires, Namba Tian Kenji immediately took the lead in breaking into the checkpoint and killing the garrison of Ashigaru with 200 horseback warriors from the Kohata Keizong as the vanguard. Immediately afterwards, Namba Tian Kenji still led Kohata Keimune as the vanguard and immediately went out again to attack the four castles of Okura, Nagamine, Makino, and Matsuru south of Kobuka.

After that, Namba Tian Kenji did not prepare to divide his troops in the presence of a lone army, and directly burned down all the longhouses and arrows in Kobuka, and took some of the grain stored here and burned down the empty granaries.

Kohata Keizune can also be regarded as inheriting the equestrian lineage of the Kohata family, and the mounted samurai under his leadership successively conquered Okura, Nagamine, Makino, and Matsuru Castle in a single day. That is, when several Ashigaru of Kobuka finally escaped back to Uenohara Castle, there was only one Naganohara Castle left in the Kato family's territory.

When Namba Kenji came later, he did not forget to sweep away Okura, Nagamine, Makino, and Matsuru. On the one hand, all the grain and grass were taken away, and on the other hand, all the facilities in the city were burned. Before leaving, he did not forget to implement the 'Banji Order' in the villages near the four places. Of course, the 'Banji Order' that was implemented in Kai Province this time was also due to the fact that the Kanto Jurisdiction had jurisdiction over the eight countries of Kanto plus Shinano and Kai.

However, the most important thing is not the grain and grass but the gold mountain. In Turyu-gun, there are Akiyama Kanzan and Otsuki Kanayama. One is in the hinterland of the Oyamada family, and the other is not far from the southern part of Naganohara Castle, where Kato is strong.

It was also thanks to Shingen Takeda who repaired roads and built water conservancy in Kai Japan. Otherwise, the Uesugi army would not have been able to conquer four cities and one level in one day. However, although there were only 15 samurai and 20 ashigaru in Uenohara Castle, Kato Torakei was still unwilling to give up the castle. He gathered all the remnants of the army to hold on to Honmaru, and asked his maids and family members to prepare to fight the Uesugi army to the end with weapons in hand.

But Namba Tian Kenji didn't eat Kato Torakei, he knew very well the truth of the speed of soldiers. He immediately sent Kohata Keizune to attack Akiyama Kanayama. And he led the remaining 7,800 troops to surround Nagano Hara Castle. After that, Namba Kenji ordered Hiraya Genbo and Yubiichi Nosei to enter the empty Ninomaru with a hundred shots each, and threw all the lit torches into the Honmaru.

Due to Kato's hasty response to the battle, it was too late to paint all parts of the city with mud to prevent fire. After the Uesugi army threw torches at Honmaru alternately, the longhouse, warehouse, and building in Honmaru were all set on fire, and a fire broke out in an instant.

Kato Toraki, a genealogical minister of the Takeda family, had no choice but to kill himself with his family in the Great Hiroma. After waiting for two hours, Namba Tian Kenji estimated that there were no living people in Honmaru, so he led his troops to join Kohata Keizune. He didn't need a head to go out this time, and the order of the court was to destroy as many fortresses and facilities as possible in various parts of the Takeda family, including the gold mines.

On July 12, after blockading Akiyama Kanayama, Kohata Keimune waited for an army led by Kenji Namba to arrive. The miners of Akiyama Kanayama were nothing more than the population plundered by Takeda Shintora and Takeda Shingen after the Shinano incident, and Namba Kenji immediately ordered all the miners to be released and let them regain their freedom. After that, they took the initiative to hand over the refined batch of 300 Koshu gold to the Uesugi army. He also took the initiative to destroy the entrance to the mine for the Uesugi Army.

The next stop for the Kamishu soldiers was the Koyamada family in the county.

Since the Yamada family's Iwaden Mountain Castle was relatively easy to defend and difficult to attack, it was impossible to break through it in a short period of time, especially when the Shangshu soldiers did not have iron artillery. In addition, there were still 300 defenders in the city. Namba Kenji immediately dismissed the idea of conquering Iwaden Mountain Castle. He still led Kohata Keizune as the vanguard, and conquered and burned several empty castles in the southern part of the Oyamada Domain, such as Shiriya, Yosamu, Tanimura, and Katsuyama Castle.

Next, the goal of the Uesugi army is Otsuki Kanayama. After the Uesugi army quickly captured the ungarrisoned Hanaseki Castle, they surrounded Iwadenyama Castle with 5,000 troops, and 2,000 troops conquered Komagamiya in the northern part of Iwadenyama Castle. The rest of the Uesugi army went to Otsuki Gold Mountain, took away the 200 Koshu gold that had been mined and refined in the mine, and destroyed the entrance.

Every move of the Uesugi army was watched by Kamada Oribe, the remaining guard of the Oyamada family, but he could not leave the city. He knew very well what the consequences would be if he left the city, after all, Iwaden Mountain Castle could not be lost, once Iwaden Mountain Castle was lost, the Uesugi army would be able to attack the Fuchu Basin directly from the mountain road of Takiko Mountain, and the losses of the Oyamada family could be compensated by the main Takeda family, and Takeda Shingen would definitely compensate. His current position as the head of the Takeda family also relies on the allegiance of a group of people in Kai Country, and if their interests are lost, Takeda Shingen must appease and compensate.

Nobushige Oyamada wanted to lead reinforcements to his own territory in the county as soon as possible to annihilate or expel the Uesugi army, but Katsunuma Nobumoto has been holding his troops at Katsunuma Castle. Katsunuma Nobumoto still has 2,000 troops in his hands, but he doesn't want to do his best for the Takeda family.

After another two days, after the Uesugi army withdrew from Iwaden Mountain Castle, they went all the way south to conquer Kotoyamayama Castle and Yoshida Castle in the south of Oyamada's territory, and won over Kobayashi Sadakin, the defender of Yoshida Castle.

Next, Namba Tian Kenji had two choices, more than half of the prefecture was swept by the Uesugi army, and then he would enter Jumo County after attacking Yatsushiro County and wait for an opportunity to enter Jumo County, or he would retreat into Sagami Tsukui County after plundering Yatsushiro County.

However, while Nambada Kenji was still thinking about it, Kato Duanzo brought bad news - Takeda Nobuyoru and Katsuyama clan Yuan led 3,000 people to the east of the river and quickly entered Jumo County.

"So far, it's only Yatsushiro-gun that has made a big fuss." Namba Tian Kenji was a little unwilling, and finally harassed around in the skills of the Takeda family, and these had to end early.

"Although our army is resting at the Jiuyi Color Pavilion, according to the current situation, we can only turn to Sone Katsuyama Castle in the north first, and Motosu Castle in the south will soon be garrisoned by Katsuyama." Kato felt that it was impossible to withdraw the same way. Takeda's response was a little quicker than expected.

Immediately, the Uesugi army marched towards Sone Katsuyama Castle. However, before they reached Sone Katsuyama Castle, they only arrived at the actual temple in the west of the castle and encountered a group of pedestrians who were somewhat peculiar.

First of all, not caravanserais. Don't look at some of them carrying large and small boxes, luggage, or pulling carts, etc., the men in the team all have swords and ribs on their bodies. This made Kenji Namba feel that he must not be an ordinary pedestrian.

Just as Namba Tian Kenji was about to ask the samurai beside him to go for questioning, he saw several people in the team not far away draw their swords and shout: "Quickly take the young lady back to the city!" ”

"Whose territory is this?" Kenji Namba immediately asked Kanzo Kato.

"Yaugawa Ling!" As if he had guessed something, Kato Duanzo immediately beckoned the ninja to take a detour and never let anyone go.

Soon, a dozen samurai were engaged in a melee with Kohata Keizunebu, the vanguard of the Uesugi army. In the sedan chair behind, a woman wearing twelve slips slowly fled towards Sone Katsuyama Castle with the support of two maids.

I have to say that although the samurai of Kai Country are brave, they can't use their arms as a car. Especially in the face of dozens of times more enemies. Soon, more than a dozen samurai were all killed, and the three women were surrounded by a dozen ninjas.

"Nambada squire, what should these three do?" Kato Duanzo is not good at making decisions on his own, so he can only ask Kenji Nambata, who is higher than his status.

"It seems that the young lady of the Yatsukawa family is not bad, take it back to the lord to see." Kenji Namba was not ready to conquer Sone Katsuyama Castle either, after all, the results he had achieved along the way had already reached the expected goal.

"Yes, these three will be handed over to us to transport back to Musashi." Kato Duanzo is still very confident in transporting people back. After all, his predecessors used to help Nagao Haruki transport the women of the minister's family from Kyoto.

Subsequently, Namba Tian Kenji and Kato Danzang soldiers split into two ways. He swaggered directly under Sone Katsuyama Castle and passed all the way through the territory of the Katsunuma family.

For the sake of Katsunuma Nobumoto's safety, Kenji Namba conquered the Heavenly Mountain Castle and Misaka Castle, which were empty in his territory. After burning down the two castles, he marched along the southern part of the previously conquered Oyamada Domain, and also conquered Yoshida Castle and Kaneyama.

And the two people who came to aid from Suruga, Takeda Nobuyoru and Katsuyama Clan, were exhausted. They were always a beat slower than the Uesugi army, and as a result, they were too late to go whenever they saw the castles being burned.

Namba Tian Kenji led the Shangshu soldiers to enter Sagami's Tsukuii Prefecture safely, and rested in the newly built Tsukui Castle. The Takeda Army didn't even see the hair of the Uesugi Army.
