MorningThe Last Morning
The 7th day of the 5th month, Keichō 20. Its moats filled in after the Winter Campaign, Osaka Castle is now defenceless. The 55,000 of the Toyotomi side leave the castle and take up their final positions at the Tennōji and Okayama approaches. Against them stand 155,000 Tokugawa troops.

ChargeSanada Charges
"There is only one target: Ieyasu's head." From Mount Chausu, Sanada Nobushige (Yukimura) and 3,500 red-armoured troops drive straight at Ieyasu's headquarters. The commander's standard goes down: the second such humiliation since Mikatagahara.

ThirdThree Charges
Once, twice, three times. Each time the red wave washes over the headquarters, the 74-year-old Ieyasu is said to have prepared himself for death. But the disparity in numbers cannot be overcome.

FallThe Finest Warrior in Japan Falls
His strength spent, Nobushige is quietly cut down in the precincts of Yasui Shrine. "Sanada, the finest warrior in Japan; nothing like it even in the tales of old." So said the enemy, the men of Satsuma, of his 49 years of life.

RoutCollapse Toward the Castle
With Nobushige's death the Toyotomi side collapses completely. One hundred and fifty thousand Tokugawa troops surge toward Osaka Castle, swallowing the retreating defenders as they go.

FlamesOsaka Castle Burns
Toward evening the keep catches fire. The next day Hideyori and Lady Yodo take their own lives in the Yamazato bailey. The Toyotomi house is destroyed, and the age of war that had lasted 150 years since Ōnin ends with these flames: the Genna peace.
