The Battle of Sekigahara, which laid the foundation of the Tokugawa shogunate

Ishida Misei, who had been favored by Hideyoshi after Toyotomi Hideyoshi's death, realized that Tokugawa Ieyasu had become the greatest threat to the Toyotomi regime, but he himself was attacked by Toyotomi warlords instigated by Toyogawa Ieyasu and forced to live in seclusion. However, during the period of seclusion, Sansei had actually been secretly wooing the names of various princes, and gradually formed an alliance against Ieyasu.

Ishida Misei was the first to lobby for Yoshiki Otani. Yoshiji Otani was the daimyō of Echizen 50,000 stones, and was praised by the people of the time as a talent who could command a million male soldiers, but unfortunately he suffered from leprosy, so his skin was easy to fall off his face, and others felt very frightened when they saw him. During his lifetime, Toyotomi Hideyoshi held a tea party where everyone took turns passing tea bowls to drink tea. However, when the tea bowl reached Ji Ji's hand, the people who were afraid of infection did not dare to pick up the tea bowl in Ji Ji's hand, and Ji Ji, who was stung, was speechless on the spot. At this time, Sancheng took the bowl in Ji Ji's hand and brewed the tea and drank it. It is said that from then on, Ji Ji believed that Sansei was his confidant.

At that time, a conflict broke out between Tokugawa Ieyasu and Echizen Uesugi Keisatsu, and Yoshikimoto had been ordered by Ieyasu to go on a campaign against Echizen, but when he reached the halfway point, he was invited by 30% to his hermitant Sawa Mountain Castle. Sansei told JiJi the truth about his intention to raise an army against Ieyasu, and Jiji, who knew that Ieyasu's powerful forces were shocked to hear this, immediately persuaded Sansei to dispel his thoughts. Sancheng persevered to persuade Ji Ji, but Ji Ji never agreed.

Although Yoshiji did not accept himself, Sansei persevered in lobbying the various forces— he succeeded in wooing Masuda Nagamori, one of the five pursuers of the Toyotomi regime, and pulling Akimoto, the strongest in Western Japan, to his side. Sansei then summoned a meeting of the princes who were on his side, and the meeting decided to detain the wives and children of the warriors who had followed Tokugawa on the expedition in Osaka Castle.

Tokugawa Ieyasu was quick to learn the news. At this time, Tokugawa Ieyasu's forces were mainly divided into two forces: the Tokugawa clan and the Toyotomi warlords who had been instigated by Ieyasu for their hatred of the civilian forces led by Ishida Sansei. When Toyotomi Takeshi followed Ieyasu on the expedition, he did not know that Sansei would suddenly make such a move behind his back, and now that his wife and children were detained, naturally an individual was panicked. Ieyasu knew that Toyotomi was only on his side out of disgust for Sansei, and naturally he was not loyal to himself. Seeing that toyotomi warriors were separated from himself, Ieyasu showed his talent for acting: "At present, all of your families are detained in Osaka, if any of you want to leave here and go back to Osaka, please go to the toilet, even if you go back to help Ishida Sansei, I will not hate, please choose your own." After a moment of silence, Masanori Fukushima, one of the Seven Tiger Generals of Toyotomi, spoke: "Now that Hideyoshi is only eight years old, what do you know?" It must have been at the behest of Ishida Sansei that the family members of me and others would be detained. As long as Ieyasu can abide by the last words of His Highness The Great Court to protect Hideyoshi, I will firmly support Ieyasu. At this critical juncture, if you are distracted from your wife and children, you are not a real samurai. After this incitement by Ieyasu and Masanori Fukushima, everyone agreed that they were ready for a war with the Osaka side.

On the other hand, the problem of hostages soon ceased to exist: the wife of Hosokawa Tadaoko, who followed Ieyasu on the expedition, was The Daughter of Mitsuhide Mitsuhide, Who was baptized catholic and changed her name to Glexia. 30% sent a man to osaka's residence to take hostages, and the fierceLyschia had his courtiers kill him—because Catholics forbade believers to commit suicide. Ishida, who learned of this, suspended plans to take the hostages. From the perspective of human nature: Sancheng is undoubtedly a righteous gentleman with principles and a bottom line, but it is precisely his principle bottom line that makes him have one less chip in his hand that is enough to balance Ieyasu.

On October 21, 1600, the Eastern Army, commanded by Tokugawa Ieyasu, and the Western Army, composed of 300,000 Western Japanese princes and daimyōs who had been drawn in by Ishida, formally clashed in Sekigahara: the total strength of the Eastern Army was about 75,000, and the Western Army was close to 100,000. It seems that the Western Army still has the advantage, but the Eastern Army is composed of only two forces, the Tokugawa clan and the Toyotomi warlords, and the internal coordination and dispatch is relatively simple; while the Western Army is the Western Japanese princes who have been drawn in by Ishida sancheng in every way, and there is no strong leadership center - in fact, the nominal general of the Western Army is not Ishida Sansei, but Maori Huiyuan, because Ishida Sansei knows that his small daimyo with less than 200,000 stone fiefs is not enough to convince the public. The complicated chain of command within the Western Army left a shadow over its victory in the war from the very beginning, and Otani Yoshiji saw it very clearly—although he had originally advised Ishida Sansei to give up the idea of confronting Ieyasu, when he learned that Ishida Sansei had raised an army, he still rushed to help at the first time, but what he said to Ishida Sansei was: "I came to accompany you to death." ”

After the formal confrontation between the two sides, the Western Army, which had the superiority in manpower, gradually gained the upper hand, but it was under such circumstances that the Western Army was unable to completely crush the Eastern Army with a single blow, because the three-way army of the Western Army always stood still: one was Yoshihiro Shimazu, one was Hideaki Kohayakawa, and the other was the Maori Army, which was the nominal general of the Western Army. In the eyes of these powerful figures, this war is the dispute between Ishida Sansei and Tokugawa Ieyasu, and they may as well sit back and watch the success or failure, and then sit back and reap the profits after the victory or defeat is roughly determined. The three-way line of troops, Hayakawa Hideaki, was stationed on Mount Matsuo, just behind the rest of the Western Army. What Ishida Sansei didn't know was that Hideaki Hayakawa had actually been secretly dealing with Tokugawa Ieyasu, and Hideaki had already made up his mind to step on two boats.

Hideaki Hayakawa intends to step on two boats, but Tokugawa Ieyasu can't wait—Ieyasu, who is in danger, urgently needs Hideaki to attack the Western Army from the rear; conversely, if Hideaki and Shimazu and Maori's legions cooperate with the other troops of the Western Army to attack themselves, they will immediately suffer disaster. It is said that at this time, Ieyasu wanted to woo Hideaki to help him, but his way of wooing his allies was very unique - shooting at Kohayakawa. Ieyasu's move is actually quite risky, in case Xiu qiu is provoked, the result can be imagined. However, the reality is that Xiuqiu was frightened by Ieyasu's shooting, and after being so stimulated, she decided to abandon the Western Army and switch to the Eastern Army.

More than 10,000 Kohayakawa troops suddenly swooped down from the mountain and attacked the rear of Otani Yoshi's army, in fact, before the war, Otani Yoshiji became suspicious of Kohayakawa Hideaki, so he arranged troops in advance to defend against the possible defection of the Kohayakawa army. However, to his surprise, Yasuharu Wakasa, Motosuke Motoki, naoho Akaza, and others who were deployed in front of the Ogayakawa Army also rebelled, so Otani Yoshiji's defense line arranged in advance to defend Kohayakawa was completely ineffective, and the battlefield situation changed to the eastern army encircling and attacking the western army, and Tokugawa Ieyasu won the Battle of Sekigahara.
