INTERACTIVE BATTLE
Battle of Funaokayama
August 1511 · Funaokayama
Hosokawa Takakuni and Ōuchi Yoshioki's forces defeated Hosokawa Sumimoto's side at Funaokayama on the twenty-fourth day of the eighth month. Shogun Ashikaga Yoshitada returned to Kyoto on the first day of the ninth month and restored his government.
Background
After the assassination of Hosokawa Masamoto in 1507, the succession to the Kyoto Hosokawa house was disputed between Sumimoto and Takakuni. When Ōuchi Yoshioki and Hosokawa Takakuni escorted Ashikaga Yoshitane to the capital in 1508, Sumimoto's faction repeatedly attempted to recapture Kyoto, building a fortress on Funaokazan to prepare for entry from the Tanba direction.
Outcome
The allied forces of Ashikaga Yoshitane, Hosokawa Takakuni, and Ōuchi Yoshioki attacked Funaokazan and captured the fortress held by Hosokawa Sumimoto's faction. Sumimoto retreated to Settsu, and Yoshitane maintained his position in Kyoto. The precise dates of the battle cannot be confirmed.
