As the eastern forces progressed up the
Tōkaidō,
Oda Hidenobu was not able to predict where the eastern forces would cross the
Kiso River and continue their westward march. To defend against all possibilities, Hidenobu set up fortifications throughout the area, with Gifu Castle at the center, dividing his forces and weakening their total strength.
Terumasa's forces Early in the morning of September 29, the combined eastern forces moved from
Haguri District's Kōda (present-day city of
Ichinomiya,
Aichi Prefecture) in
Owari Province to the neighboring Haguri District's Kōdajima (present-day city of
Kakamigahara, Gifu Prefecture) in
Mino Province. (The two Haguri Districts had previously been one district in Owari Province, hence their same names and proximity.) During their march, they crossed the Kiso River. While crossing the river, a contingent of Hidenobu's musketeers fought their advance in the
Battle of Kōda Kisogawa Tokō (河田木曽川渡河の戦い
Kōda Kisogawa Tokō no Tatakai) against
Ikeda Terumasa's forces. After defeating the musketeers, Terumasa's forces continued their march. On the afternoon of September 29, they arrived in the village of Komeno (present-day town of
Kasamatsu) and fought a force of 3,000 men under
Dodo Tsunaie (百々綱家) at the
Battle of Komeno (米野の戦い
Komeno no Tatakai) and defeated them. At the time of the defeat, Hidenobu was in the nearby village of Injiki (present-day
Ginan) and decided to remove his forces to Gifu Castle, instead of attacking the eastern forces where they were.
Masanori's forces Around the same time, Masanori's forces tried to cross the Kiso River near Owari Province's
Nakashima District (present-day Ichinomiya), but they found western forces deeply entrenched on the opposite banks and decided to head further south to cross the river. They eventually crossed at Higashikaganoi and traveled by
Kaganoi Castle (加賀野井城
Kaganoi-jō) (in present-day
Hashima, Gifu Prefecture) before they turned north and surrounded
Takegahana Castle.
Sugiura Shigekatsu (杉浦重勝) initially resisted Masanori's forces, but
Mōri Hiromori (毛利広盛), the leader of his supporting forces, capitulated to Masanori's, and Shigekatsu had no choice but to do the same and Takegahana Castle fell. After the victories by Terumasa and Masanori, the two forces joined at the
Arata River (荒田川
Arata-gawa) south of Gifu Castle to begin their final advance. ==Battle==
