小早川秀秋
Yoshitsugu was at the head of about 600 men, with another 4000 or so under Toda Shigemasa, Hiratsuka Tamehiro, Ōtani Yoshikatsu (his son), and Kinoshita Yoritsugu. As the battle raged on, Kobayakawa Hideaki, who was situated above Yoshitsugu on Mount Matsuo, didn't move, despite repeated calls from Ishida Mitsunari. Yoshitsugu suspected something, and thus called for his troops to position themselves so as to prepare for a possible attack from their flanks. His hunch was right, as following a stimulatory gun volley from Ieyasu's position, Kobayakawa Hideaki and his troops rushed down the mountain towards Yoshitsugu's position. This movement was immediately followed by Akaza Naoyasu, Ogawa Suketada, Kutsuki Mototsuna, and Wakizaka Yasuharu, a total of over 20,000 troops.
