Oda Nobunaga Is a vassal in front of the unification of the world, Akechi Mitsuhide I have committed suicide in response to Mr.'s rebellion.
"Honnoji Incident" is not it.
The motive for Mitsuhide's rebellion is unclear, and it remains a mystery to this day.
And because it is a mystery, there are many theories.
"Ambition theory" aiming for the world .. This is exactly like the Warring States period.
The daily grudge exploded "grudge theory" .. There are various theories about this, but it seems that Nobunaga's unreasonable behavior toward Mitsuhide was quite fierce.
And, "black curtain theory" that Mitsuhide had a black curtain. is.
The imperial court and Ieyasu Tokugawa Mr., and Hideyoshi Toyotomi Names such as Mr. will go up.
While many theories are flying around, this time "Shikoku theory" I would like to introduce about.
At the museums and museums in Okayama Prefecture in 2014, "a certain letter" at that time Was announced and made a noise.
The letter is a letter of exchange between Mitsuhide's chief vassal and the military commander who ruled Shikoku five months before the Honnoji Incident.
With this discovery, the truthfulness of the "Shikoku theory" has emerged.
Let's move on to the strange "Shikoku theory" of Honnoji.
Actions before "Honnoji Incident" by Oda Nobunaga's vassals!
Hashiba (Toyotomi) Hideyoshi
1577 5 years before "Honnoji Incident" Since then, he has been entrusted with the conquest of the Chugoku region, which is the sphere of influence of Mr. Mouri.
At the time of confrontation with the Mouri army, which is also the final push for "Chugoku Campaign", Hideyoshi requested Nobunaga for reinforcements and sent Akechi Mitsuhide's army first, but along the way, "Honnoji Incident" It happened, didn't it?
Hideyoshi will return to Kyo with the unfinished conquest of China.
Katsuie Shibata
Appointed as a military commander in the Hokuriku region, Sengoku warlord Kenshin Uesugi Will be in conflict with Mr.
He is the chief retainer of the Oda clan.
Even when the "Honnoji Incident" occurred, he was in battle with Uesugi and was sent news, and he made a big mistake that Hideyoshi's army would defeat Mitsuhide first, so that Hideyoshi would threaten his position. It becomes.
Kazumasu Takigawa
" Nagashino " famous for Oda Gun Squadron vs Takeda Cavalry Battle " And the one who took the overall command of the gun corps.
Furthermore, Nobunaga's firstborn, Oda Nobutada , was involved in the "Koushu Conquest" that destroyed the Takeda clan. As an assistant to Mr. Takeda, General Takeda, Katsuyori Takeda He has been credited with taking his head.
Kozuke Ueno Given (currently Tochigi) and Shinano Province (currently Nagano), Kanto agent Was ordered.
Nobutaka Kobe, Nagahide Niwa
Nobutaka Kobe Is Nobunaga's 3 sons So, I was adopted by the Kobe family and succeeded to the family.
He will move to various places as a corps of the Oda clan with Kazumasu Takigawa and others.
Nagahide Niwa Is the person who was given the position of the second chief retainer following Shibata Katsuie, "Oda clan's two heroes" Is called.
And, as the subject of this story, Chosokabe in Shikoku Negotiations with him broke down, and Nobunaga decided to "conquer Shikoku" and ordered Nobutaka as the general and Nagahide as the deputy general.
Mr. Akechi Mitsuhide was in charge of acting as an intermediary with Mr. Chosokabe.
Akechi Mitsuhide and "Shikoku Theory"!
Is Oda Nobunaga and Chosokabe a good relationship?
Chosokabe who achieved the unification of Tosa Province (currently Kochi) ex-parent He had a good relationship with Nobunaga and was relieved of his territory.
Nobunaga also "Shikoku can be selfish!" It was like that.
If you say so, your ex-parents will also try to extend their power to the remaining three countries in Shikoku.
Mr. Miyoshi, who ruled Awa (currently Tokushima) and Sanuki (currently Kagawa), was hostile to Nobunaga, but Miyoshi Yasunaga When he loses to Nobunaga, he is famous "Crescent's Leaf Tea Pot " As a vassal, he will be treated as a vassal.
Mr. Yasunaga is also close to Mr. Hideyoshi, and Hideyoshi's older sister's child (later Toyotomi Hidetsugu I was adopted by Mr.).
When the territory is robbed by a former parent, he appeals to Nobunaga and tries to withdraw the policy of the Oda clan.
Nobunaga "You can like Shikoku!" I told my ex-parents, but "After all, only in Tosa and Awa, return the other territories!" I changed my mind.
The ex-parents were furious and dissatisfied with this and refused his request.
And Nobunaga, with his third son, Nobutaka Kobe, as the general, "Shikoku Campaign" I ordered.
What is the relationship between Akechi Mitsuhide and Chosokabe?
Mitsuhide's vassal Yoritatsu Ishitani And Toshimitsu Saito I have a brother named Mr.
His younger brother, Toshimitsu, is a senior vassal of Mitsuhide and participated in the Honnoji Incident. Immediately after "Battle of Yamazaki" And he died with Mitsuhide.
Tokugawa 3rd Shogun Tokugawa Iemitsu Nanny's Lady Kasuga Is my father.
His older brother, Yoritatsu, is a military officer under the direct control of the Shogun in the Muromachi Shogunate. Mitsumasa Ishitani I was welcomed as a son-in-law to Mr. Mitsumasa is also the remarriage partner of this brother's mother.
In addition, Mitsumasa's other daughter is Chosokabe Motochika's regular room . It will be. Mr. Yoritatsu and his ex-parents are brother-in-laws.
Later, when the Muromachi Shogunate disappeared, Mitsumasa became a vassal of his ex-parents, and Yoritatsu became a vassal of Mitsuhide.
So, Mr. Akechi Mitsuhide was in charge of the "Shikoku territory problem" of Mr. Nobunaga Oda and Mr. Chosokabe Motochika, and it was Ritsu, Toshimitsu brothers and their adoptive father, Mitsumasa. That is to say.
What is the content of the discovered "letter"?
January 1582 , A letter addressed to Mitsumasa Ishitani by Toshimitsu Saito five months before the Honnoji Incident.
"I would like to ask the ex-parents to persuade you to send your brother, Ryota." The content.
You can see the conflict between Nobunaga and his ex-parents around this time.
May 1582 , A letter from Chosokabe Motochika to Toshimitsu Saito in the month before the Honnoji Incident.
As of January, he was a former parent who refused Nobunaga's order, but in this letter,
"I want to keep the territory that is the entrance to Tosa Province, but I will follow Nobunaga's life." It was such a content.
I don't know if Nobunaga had read this letter, but he was trying to send Nobutaka Kobe to the Shikoku Campaign even though his ex-parents showed an attitude of obeying orders.
The fact that Mitsuhide, who was the agent, was crushed by this, re-emerged the "Shikoku theory" as the motive for causing the Honnoji Incident.
Summary
It is said that the discovery of this letter may have motivated Akechi Mitsuhide to cause the Honnoji Incident in this "Shikoku theory".
It has been negotiated as an agent for a long time, but in the end it was said to be a "grudge theory" due to the fact that the route was changed to the use of force and the face of leaving the general to another person was crushed. I did.
However, from the contents of the "letter" discovered this time, it seems that Chosokabe was also a close relative of his vassals, so he might have protected it from Nobunaga who was about to destroy it.
If this theory is true, then Akechi Mitsuhide is definitely a "hero of the Warring States".
