予て[かねて] (kanete)

かねてから 予定よていしていた 長期ちょうき 休暇きゅうかを 取とった

I took the long vacation that I had been planning for a long time.

しかしながら、正午頃、予てより懐柔策をとっていた小早川秀秋の軍が西軍を裏切って東軍に味方することを決意し、西軍の大谷吉継隊に襲いかかったのを機に形成が逆転する。

However, around noon, the army of Hideaki KOBAYAKAWA, which Ieyasu had tried to take into his side, decided to change its support to the eastern side from the western side, and rushed to attack Yoshitsugu Otani's troops on the western side, changing the fighting state to the advantage of the eastern side.
