How Did Sekugawa Win The Battle Of Sekigahara?

The battle of Sekigahara was won before the actual battle

During October the 20th, a great battle between two of the biggest armies during the Azuchi-Momoyama period had occurred. This battle was the decider of who would obtain control over Japan for the next 200 years. The statement ‘The battle of Sekigahara was won before the actual battle’ is only true to an extent, though much preparation was put into the near guarantee victory of it. Ieyasu Tokugawa was the shogun and leader of the massive faction known as the eastern army, to march into the battle of Sekigahara.

Tokugawa’s Eastern army consisted of the following smaller factions: Honda Tadakatsu, Hoskawa Tadaoki, Li Naomasa, Matsudaira Tadayoshi, Tsutsui Sadatsugu, Arima Toyouji, Asano Yukinaga, Fukishima Masanori, Ikeda Terumasa, Ikoma Kazumasa, Kanamori Nagachika, Kato Yoshiaki, Kuroda Nagamasa, Kyogoku Takamoto, Oda Yuraku, Tanaka Yoshimasa, Terazawa Hirotaka, Todo Takatora, Yamanouichi Kazutoyo, and Yoshida Shigakatsu. These Generals and their men were collected and had agreed to fight for Tokugawa. Ishida had gathered up three more factions than Ieyasu, at a total of 24. Though little did Ishida Mitsunari know that Ieyasu had acquired and placed many spies within those armies and was able to obtain information that may have impacted the upcoming
This reason contradicts the fact that Tokugawa had won the battle before it began, as their superior abilities in battle were able to sustain themselves until Ieyasu had made the call of a counter attack and the beginning of the backstabs against Ishida
