KIKUCHI Yōusai

This is a scene from the Battle of Ichinotani, where the Genji and Heike clans fought.
The Taira clan had set up an impregnable camp at Ichinotani, and Minamoto no Yoshitsune came up with a bold plan to surprise the Taira clan from behind rather than attacking them from the front, by galloping down a steep cliff on horseback.
