The members of Wakae Hachinin-shu were also grateful for Mitsunari who tried his best to save Hidetsugu's life, and in return, they fought to protect the army headquarters of Mitsunari ISHIDA during the Battle of Sekigahara, which started in 1600 (However, not all the members served Mitsunari, as there were exceptions such as Yoshimasa TODO who served his cousin Takatora TODO and Kinai YASUI who served Yoshinaga ASANO).
また、若江八人衆も秀次助命のため最後まで奔走した三成に感謝し、慶長5年（1600年）の勃発した関ヶ原の戦いでは石田三成軍の本陣を死守する獅子奮迅の戦いをしている（ただし、藤堂玄蕃は従兄弟の藤堂高虎に仕え、安井喜内は浅野幸長に仕えるなど、必ずしも全員が三成に尽くしたわけではない）。
