How could Oda Nobunaga beat Yoshimoto Imagawa before? I wrote an article called.
In that article, a small number of Oda troops surprise attack from the mountain behind the Imagawa army resting in the Okehazama. I wrote that I won.
Interpretation of Okehazama between Nobunaga Kouki and Nobunaga
[Nobunaga Kouki] and [Nobunaga Ki] are the historical materials for investigating the battle between Okehazama. there is.
Nobunaga Is [ Shincho Kouki ] Based on original research and interpretation It was published in the Edo period. Since it is based on Nobunaga's official record, there are many similarities in the depiction of the battle between Okehazama.
Although the depictions are similar, there are some significant differences.
It is said to have caused a surprise attack [ mountain behind 】is.
Shincho Kouki Then, Nobunaga moved from Zensho-ji Fort, moved to Nakajima Fort, and attacked the Imagawa army, which had a camp in the hills, from the mountainside . Is written.
On the other hand, Nobunaga Then, I went around to the mountain behind the Imagawa Honjin directly from the Zensho-ji Fort without going through the Nakajima Fort, and attacked from above the Imagawa army . It has been.
[Attack from the mountainside] and [Attack from the mountain behind] Then, the meaning is different.
The base historical material, Nobunaga Kouki, was not published in the Edo period, and the [Nobunaga Ki] written based on Nobunaga Kouki was generally published and read by many Edo townspeople.
Perhaps because of this, Nobunaga's depiction spread among the common people, and that became a popular theory.
The battle between Okehazama was a frontal breakthrough! ??
In the Meiji era, the Army General Staff Headquarters [ War History ] I started my research.
Among them, [ Battle of Okehazama When editing 】, Nobunaga led 2000 soldiers through a detour to approach Yoshimoto's main corps and launched a surprise attack from the top of the mountain . I came to the conclusion.
The Army General Staff, a military expert, adopted this theory, and the [ detour surprise attack theory ], But it has become a popular theory and will be introduced in many media.
For some time, this detour surprise attack theory has long been a popular theory.
However, the one that cast a stone on this theory was the [ frontal attack theory , which has been advocated by history researcher Masayuki Fujimoto since around 1980. 】is.
Mr. Fujimoto is highly creative [ Nobunaga ], But [ Shincho Kouki ] Was insisted on being trusted. As a result of scrutinizing this Nobunaga's official record, Nobunaga's theory that he attacked the Imagawa army head-on without detouring Was announced.
Yoshimoto, who set up his headquarters in the Okehazama, set up his camp in the northwest direction.
Nobunaga, who left Fort Nakajima, is Yamagiwa * . When you march to, it will start to rain suddenly.
Heavy rain, like hitting stones and leopards, sprinkled from behind Nobunaga and hit the Imagawa army violently. * The mountainside here is explained as being between Okehazamayama, where Yoshimoto was headquartered, and Fort Nakajima.
Fort Nakajima is a flat land, and Okehazama is a hilly area.
Assuming that the place where the flat land touches the hills is exactly the mountainside, it is presumed that the former army of the Imagawa army was stationed at this mountainside.
Nobunaga sees the heavy rains stop and the sunny days spread, and attacks the former army of the Imagawa army, which is set up on the mountainside. Imakawa, who did not expect a small number of Nobunaga troops to launch an attack from the front, was suddenly confused.
The onslaught of Nobunaga's army caused the former army to collapse, and it spread to the Yoshimoto headquarters who had been standing behind, resulting in a total collapse, and as a result, General Yoshimoto Imagawa was beaten.
This theory is advocated by Mr. Fujimoto [ front breakthrough theory 】is.
Of course, there are some questions in this theory as well.
There is no description in Shincho Kouki that he launched an attack on the former army of the Imagawa army.
Was the Imakawa army weak enough to easily collapse into an attack by Nobunaga's army, no matter how ambushing it was? The question remains.
Regarding this idea, it is unlikely that the Oda clan, who had settled Owari (570,000 stones), had only 2000 troops, and in fact led nearly 10,000 troops . It is also thought that it may be.
[Detour surprise attack theory] and [Front breakthrough theory] It is not clear which is correct, but it goes without saying that the Battle of Okehazama, which is the most famous battle in the history of the Warring States period, became a turning point in the history of the future.
