Just when the Uesugi army was overwhelmed, Honma Masayasu was still unwilling to submit to the Uesugi family. Obviously, Honma Masayasu overestimated the strength of the Kuchi Honma family and underestimated the strength of the Uesugi army.

In the early morning of March 31, Honma Masayasu led 800 troops to the outside of Ryotsu Minato Castle. The castle was defended by three divisions, including Haguro Shinano, Nishi-Wakasa, and Higashi-Nasaemon, with a total of 300 troops. Ryotsuminato was crucial to the Uesugi army on this expedition to Sado. After all, all the ships on which the 4,000 Uesugi troops who crossed the sea were here. If this place is captured by Honma Masayasu, then in the event of an unfavorable battle, the 4,000 Uesugi army will not be able to return to Echigo.

Honma Masatasu relied on his superiority in strength to immediately launch an attack on Ryotsu Minato Castle. However, Honma Masayasu did not think in advance that the Uesugi army defending the castle still had iron cannons in their hands. Just as the Kuchi Honma army launched its first attack, the Kaneko University Sukebu, which was entrenched in Ninomaru, used two hits from twenty iron cannons to instantly repel the Kuchi Honma army. It also caused Miyaura Soshiro, a heavy minister of the Kuchi Honma family, to be killed by the defenders.

After seeing his retainers shot by the defenders, Honma Masayasu instantly realized that Ryotsu Minato Castle was not a bone to gnaw on. If the army is withdrawn at this point, how will Honma Takana, the wealthy Nagoya Takama, and others feel about it? Moreover, Masahru Honma of Akatama Castle is still staring at him all the time, and if he loses this battle, then there will be a reason for him to make it difficult. After thinking about it, Honma Masayasu still felt that he had to continue to fight, and he couldn't back down.

At the same time, Yasuda Keimoto, Kaneko University Suke, and Shibuya Makiyo easily captured the two cities of Shinho Castle and Guayuya Castle, which were guarding the emptiness. Kitami Takamitsu of Kumagai Castle in Zatai County hurriedly led an army of 100 after learning that Shinho Castle and Guashengya Castle had been lost, but was completely annihilated by Yasuda Keimoto and his troops under Shinho Castle.

However, Kan Ryokai will not give Honma Masayasu a chance to capture Ryotsu Minato Castle. With Takaya Mizuhara and Kiyotaka Noborisaka under the leadership of Hidetoshi Osakami and Takahide Sawane, before they reached Akatama Castle, the defender Honma Masaharu opened the castle and surrendered. And the defender of Matsunozaki Castle, Honma Takaharu (Honma Takanobu third brother), learned that Akatama Castle was opened, and directly abandoned the castle and fled to Hamo Castle. Subsequently, Mizuhara Takaya and Nobosaka Kiyotaka captured two castles bloodlessly along the way. Takashi Mizuhara and Kiyotaka Nobosaka didn't let Masaharu Honma, who took the initiative to surrender, idle, and asked him to find a way to make Ogura Castle open. Once Hisashi knew that most of the Honma family's territory in Kamo County was lost, Honma Masayasu would no longer keep an eye on Ryotsu Minato Castle.

At noon the next day, outside the city of Liangzu, the main battle of the Honma army was known for a long time.

"Report to the Lord, something is wrong! Shinho Castle and Guayuya Castle were captured by the Uesugi Army, Yasuda Echichu Mamoru and Kaneko University! "Just as Honma Masayasu and Honma Takana, Nagoya Takama and others were eating a bento in Honjin, an envoy ran in in a panic and reported the news to them.

"What?! How can it be?! Isn't the Uesugi Army still in Yoshii Castle? Even if you send troops, you will come to the nearest Ryotsu Minato Castle! Honma Masatasu said after swallowing a mouthful of rice.

"It's indeed the Uesugi Army, and the Shibuya Army!" Makeban explained.

"Tell the Lord! Akatama Castle opens up and surrenders to the Uesugi Army! Matsunosaki Castle's defender, Honma Saemon Captain Takaharuden, fled back to Hamo Castle! "Not long after the previous envoy came, another envoy hurriedly ran into the main formation.

"The Uesugi army still dares to divide its troops?! Aren't you afraid of being attacked by Sado Kazuku, Hamo Honma, Kawarada Honma, etc., and all of them will be wiped out? Honma Masayasu couldn't understand why Kan Ya Kei was acting the way he did.

"That's because of the help of Shibuya, Sawane, and Osakami! These three families have long hooked up with the Fuchu Nagao family, and now with the three of them leading the way, the Uesugi army doesn't have to worry about anything at all. The Hamo Honma family originally had an in-law relationship with the Fuchu Nagao family, but I am afraid that the Hamo Honma family will also fall to the Usugi family through this relationship! Honma and Juro of Ichimen said angrily.

"Now let's think about what to do! There were at least 2,000 Uesugi troops in Akatama Castle and Guashengya Castle. In addition, there are at least 1,000 Uesugi troops in Yoshii Castle, as well as the three families of Sawane, Shibuya, and Osakagami, how many troops does the family have that can fight the Uesugi army? It is better to surrender the Uesugi army with Sawane, Shibuya, and Osakami at that time, at least they can still be able to block it. Now that they are all facing each other with the Uesugi family's swords, their skills have become a luxury! "Honma Takanna is not thinking about the survival of the main family at this moment, but about the safety of his own territory and family.

"You!" Honma Masatasu was so angry that he even fell to the ground with a bento.

"Your Majesty has retired first!" Honma Takana then left the main camp without looking back, and took more than 100 troops with him as he left.

With this walk of Honma Takana, it was like a domino. This was followed by Nagoya Takamasa and others. In just one afternoon, there were only more than 100 people left outside the city, including Honma Masayatsu's flag book and Honma and Juro. Honma Masayasu could only look up to the sky and sigh before withdrawing his troops and returning to Kuchi Castle. Just as he entered Kuchi Castle, he learned that Honma Takana and Nagoya Takamasa were ambushed by the three coalition forces of Shibuya, Sawane, and Osakami on the way back to Shinho Castle and Guayuya Castle, and more than 200 people were taken.

Just after Honma Masayasu withdrew his troops and returned to Kuchi Castle, Mizuhara Takaya and Yasuda Keigen led an army of 2,000 to the north to capture Shiinari Castle and Kazaki Castle. The three men of Ryotsuminato Castle, Haguro Shinano, Nishiwakasa, and Tomei Saemon also went out of the castle to join up with Mizuhara Takaya and Yasuda Keimoto, and surrounded Kuchi Castle.

Honma Yama Castle Mamoru in Zatai County and Honma Takanobu in Hamo County and others could only watch as all parts of Kamo County were captured by the Uesugi army and could not do anything. One of the most powerful high-ranking masters on Sado Island, Shimoo Sado Mamoru and others were quickly defeated by the Uesugi army and scattered and fled, and at present, the anti-Uesugi forces in Zata and Hamao counties are more than capable of self-preservation, and as for the difficulties of friendly forces, they can only watch from the sidelines.

Gan Ryo Keichi led the army alone to merge with Shibuya Masada's headquarters and captured Iwataniguchi Castle and Washizaki Castle, killing more than 200 people. After capturing Iwataniguchi Castle and Washizaki Castle, he withdrew his troops and returned to Yoshii Castle, and as for the Shimoo Sado Code that was guarded in Irikawa Castle, it was handed over to Shibuya Mataka to solve, after all, the enemies were very angry when they saw each other, and Kanya Keiji had other things to do.

The reason why Kaganya Keichi made Shibuya Mataka take charge of the attack on Irikawa Castle was entirely because the island of Sado was a "dead place" and "important place" in the art of war for the 4,000 Uesugi army. What is a "dead place"? An area where you can survive if you fight quickly, and an area where you can't fight quickly will wipe out the entire army is called a dead land. What is "heavy land"? An area that goes deep into the enemy's hinterland and is backed by many enemy cities is called a heavy land.

At this moment, as the commander-in-chief, Kagan Keichi must do two things well: first, go deep into the important land, and must seize a considerable amount of grain and grass to prevent the Sado people from fighting a protracted war and a war of attrition with the Uesugi army; 2. At this time, the Uesugi army was in a dead end, and it was necessary to fight for survival, and it was not possible to completely pin its hopes on the strength of the three families of Asakami, Sane, and Shibuya, let alone on the reinforcements from the Echigo side.

After all, the four families of the Hamo Honma family, the Kawamada Honma family, the Zata Honma family, and the Kuchi Honma family are the big lords of the three counties of Sado, and they can all gather an army of nearly a thousand people. Coupled with the strength of the Shimoo Sado Mamoru and the high-ranking masters of the Kita-Sado group, the Uesugi army was completely at a disadvantage in terms of strength.

At this moment, what Kanya Keimochi, Yasuda Keimoto, Mizuhara Takaie, and Nobosaka Kiyoko were most worried about was that the national lords of Sado would unite to fight against the Uesugi army, so that fighting in a different place and far away from their own country would make it very difficult for the Uesugi army to supply its own armaments, military rations, and troops, and if they wanted to achieve victory, they could only fight quickly. Otherwise, even the three wealthy families of Osakagami, Sawane, and Shibuya, who were on their side from the beginning, would gradually lose confidence in the Uesugi family and even fall to the enemy.

On April 1, Honma Masayasu burned Honmaru with a fire in desperation, and committed suicide with his family, retainers, and surnames in the burning Honmaru. The Kuchi Honma family, one of the Honma family streams, disappeared from people's sight.
