a fire broke out within the castle, greatly damaging the defences. Shingen seized the opportunity to mount an assault that evening, in which Kasahara was killed. Aftermath The fall of Shika spurred Murakami Yoshikiyo, the most powerful Shinano daimyō, into moving against the Takeda, and in 1548 he succeeded in defeating Shingen at Uedahara. However this was only a temporary setback for Shingen, who went back on the offensive in Shinano in 1550 and drove Yoshikiyo out of Shinano after the 1553 Siege of Katsurao. This in turn prompted a renewed Uesugi intervention in Shinano, led by their new daimyō Uesugi Kenshin, which culminated in the famous Battles of Kawanakajima. In popular culture Takeda Shingen's famous display of severed heads before the walls of Shika is depicted in the 1969 Japanese film Fūrin Kazan ('Samurai Banners'), which follows the careers of Shingen and his general Yamamoto Kansuke.
