The last resistance of the Osaka Garrison was at Tennoji, outside of the castle. Hideyori, son of the legendary Toyotomi Hideyoshi, made up a plan to try and turn the tide of the siege. Akashi Morishige was to attack the Tokugawa in conjunction with Sanada Yukimura. But the Tokugawa were led by Ieyasu himself, and even though Ieyasu was wounded by a spear thrust, Yukimura was killed in action. Thus, Morishige's attack failed as well. This left only Hideyori to defend the castle. The Tokugawa cannon began pounding the keep, and hopeless, Hideyori committed seppuku.
