In desperation, Honda Tadakatsu had no choice but to order his son-in-law Sanada Nobuyuki to take over Sakai Ieji's military power, and send Sakai Ieji himself back to the main camp to wait for Tokugawa Ieyasu's fate. Sanada Nobuyuki was the sister-in-law of Sanada Masayuki, the head of the Shinano Sanada clan, and became a member of the Honda clan because he married Honda Komatsu, the adopted daughter of Tokugawa Ieyasu and the eldest daughter of Honda Tadakatsu, and became a retainer of the Tokugawa family with 27,000 koku of Numata Castle, while his father Sanada Masayuki was based in Uedahara of 38,000 koku and still existed as a daimyo.

The feud with the Tokugawa clan led to a fierce dispute between Sanada Masayuki and his son over which side to turn to. Sanada Masayuki, who intends to make the Sanada clan bigger and maintain his position, hopes that Sanada Nobuyuki can hand over Numata Castle and integrate the power of the Sanada clan to help Hideho watch the Nakasendo and stabilize Shinano; Sanada Nobuyuki, on the other hand, due to his status as Honda's son-in-law, asked Sanada Masayuki not to be obsessed, immediately join the Tokugawa side, and together with the daimyo of Minami Shinano, form a Shinano crusade army, block Hideho's retreat, and unite Horiri, Murakami, and Mizoguchi in Hokuriku to attack Echichu and Kaga.

Due to the great difference of opinion, neither father nor son was able to convince each other in the end. In a fit of rage, Sanada Nobuyuki led 900 men to leave Honto and go to Edo, where they joined Honda Tadakatsu's team.

Out of love for his eldest daughter Komatsu, Honda Tadakatsu valued this son-in-law very much, and half of the three thousand sergeants were under his command. Sanada Nobuyuki is also grateful to this father-in-law, and he did his best before and after the saddle.

After receiving Honda's instructions, Sanada Nobuyuki immediately went to the Sakai army to take over the command, and without being questioned by General Sakai, he immediately led 6,500 people to the main battlefield to support Honda Tadamasa.

Meanwhile. Okubo Tadatsune and Yasumasa Honda, who were guarding the last position on the northern flank, were attacked by Fukushima Masanori and the people. Due to Yubara's Tokugawa tripart, Okubo Tadashi was unable to take the initiative to pursue the Toyotomi army; However, Honda Yasushige did not want to be passive everywhere, and rushed out of his position several times to fight fiercely with Fukushima Masanori. However, the disadvantage of troops and the death of the two brothers of Ohei Jiachang made the morale of this army low. Unable to fight the high-morale Toyotomi army, Honda Yasushige accepted Okubo's proposal to withdraw to his position and send 2,000 men to support Yubara's Tokugawa Sanbu.

The so-called good things don't go out and ugly things spread thousands of miles, and the death of Naomasa Ii and the annihilation of Akabi's entire army soon spread throughout the Hibara battlefield. Among them are also the three divisions of Yasumasa Kamihara, Mamotsuna Watanabe, and Tadamasa Mizuno from the Yubara Division.

As the first Tokugawa army to enter the battle, Kamihara Yasumasa has lost most of his army, not only that, because he insisted on the Yubara raid on Hideho's main camp, Watanabe and Mizuno also fought a war of attrition, in front of the tenacious Fukushima Takayoshi, the Tokugawa army's strength advantage gradually disappeared, as of the news of the death of Ii Naomasa, Kamihara Yasumasa only had 3,000 people left, and Watanabe and Mizuno had a total of 3,500 people. Fukushima Takayoshi's 9,000 troops were only 6,000 men, and the gap between the two armies narrowed to several hundred, and the death of Naomasa Ii was even worse, becoming the last straw that crushed the Tokugawa Sanbu.

"The southern flank has been lost, and there is no point in holding on here. I hope that your lordship will evacuate the battlefield with us and go to this camp to escort you! Watanabe Moritsuna came to Yasumasa Kamihara and suggested eagerly.

He didn't know that Yasumasa Kamihara was already red-eyed, how could he retreat in this situation?

"Hanzo doesn't need to say much," Yasumasa Kamihara replied with a serious expression, "Both the north and the south have been lost, if we retreat, won't we let the enemy army press down?" As long as we hold our positions, we will be able to contain more than 10,000 troops and create conditions for the lord's counterattack. Although the ending may be the same as that of the Ii Bingbu... Killed on the battlefield. But isn't it worth exchanging our humble lives for the lord to reign over the world? ”

"But my lord," Watanabe Moritsuna, unwilling to give up, still persuaded him, "I heard that Honda Yasushi also led his army to retreat to the Okubo position at the east exit, so it is better to retreat here." Convergence with it, concentrating forces and fighting with Izumo Mamoru may be able to turn things around. ”

"Hanzo!" Yasumasa Kamihara glared angrily, "Is this what you or Fujijuro mean?" ”

"This ......" Watanabe Moritsuna lowered his head in shame and said, "I think Fujijuro's words are not unreasonable......"

"Coward!" Yasumasa Kamihara scolded: "In the battle of Changshino, you and the others also fought hard and never retreated, but now it is good, and the situation is unclear and they are clamoring to retreat?!" Could it be that ten years of comfortable life have buried your samurai hearts?! Hanzo, you tell me that Fujijuro can leave if he wants to escape, and Yasumasa will never stop him, and he doesn't need these high-sounding excuses. As for you, go with him, but please leave the more than 1,000 troops under your command to me, Yasuma does not want these loyal samurai to be infamous because of you! ”

"Your Excellency!" Watanabe Shougang's face was pale, and he stopped talking, "Hanzo just said that, he didn't really want to retreat, and besides, it was not a ploy to avoid the edge for the time being......"

"Bastard!" Yasumasa Kamihara slammed his whip on Watanabe Moritsuna, and scolded loudly: "It's all this time, what are you still arguing about? I've said it all, get out of here, don't disturb the morale of the army here, you are cowards, but we Samurai of the Three Rivers are not! Go to Okubo and let the old man prove what the way of a samurai is! ”

Watanabe Moritsuna gritted his teeth in pain, glanced at Yasumasa Kamihara and was defeated by his angry eyes, and immediately dismounted and bowed: "I have insulted the prestige of the Samurai of Mikawa, and I ask for your forgiveness!" I'm going to go back and explain to Fujijuro that he can support the adults with him! ”

"What you do has nothing to do with me, but if you drag down the lord, Kang Zheng will not let you go even if he dies!" Yasumasa Kamihara let out a loud shout, and rode his horse towards the center of the battlefield - this was his fourth attack, and although he was mentally prepared for defeat, two lines of old tears still crossed the corners of his eyes and drifted away with the wind at the thought of dying on the battlefield.

Yubara and the main battlefield were both at a disadvantage, and the northern and southern flanks were even more defence-based, and in this situation, both Honda Masasumi and Okubo were loyal neighbors, and both advised Tokugawa Ieyasu to withdraw his troops and return to his skills, and use the Battle of Cage Castle to buy time for Mori Terumoto in.

But Tokugawa Ieyasu was extremely resolute, he sat on the mazar and drank tea silently, without saying a word, as if waiting for something.

"Lord, the reinforcements from the northern Sichuan of the Right Mansion have not yet arrived, and the retreat at this time can preserve the strength!" This is the fourth time that Okubo has admonished Tokugawa Ieyasu, but Tokugawa Ieyasu still shook his head and said calmly, "Wait, wait." ”

"What are you waiting for?" Honda Masanobu turned sideways and asked Honda Masanobu.

Honda Masanobu smiled and said nothing, at this moment, an envoy came to the front of the tent of the main camp, only to see him in the dust, wiped the dirt off his face, knelt down on one knee and said: "Lord Kaiyu, Lord Yoshikawa has bypassed the small hinoyama and arrived at the abbot plain, ready to attack the main camp of the right house at any time!" ”

"It's finally here," Honda Masanobu and Tokugawa Ieyasu smiled at each other, while Honda Masanobu and Okubo Tadashi woke up from a dream and bowed deeply to Ieyasu.
