Location
Cause → Event → Consequence
A Toyotomi-loyal fortress controlling a section of the Kizu River near Osaka posed a strategic obstacle to the Tokugawa shogunate's military campaign. Following a reconnaissance mission to assess the position, Tokugawa commanders planned a coordinated multi-directional amphibious assault to neutralize it and advance their siege of Osaka Castle.
Tokugawa forces executed a two-pronged assault on the Toyotomi fortress along the Kizugawa. Ishikawa Tadafusa led 2,300 men across the river by boat from the west, while forces under Hachisuka Yoshishige attacked simultaneously from the south and east, combining amphibious and land-based pressure on the garrison.
The coordinated assaults succeeded and the fortress fell to the Tokugawa. This cleared Toyotomi resistance along the Kizu River, strengthening the Tokugawa siege of Osaka and contributing to the eventual destruction of the Toyotomi clan and consolidation of Tokugawa control over Japan.
