Sangokushi: The Yangtze Is Burning!

Covering roughly 13 years, from Cao Cao's victory over Lu Bu in 198 CE, through the Battle of Red Cliffs in 208 CE, and the aftermath up until 211 BCE. As other players are swept from the board, the story focuses on Liu Bei and his increasingly desperate attempts to prevent Cao Cao from seizing all of China. The turning point is Liu Bei's recruitment of the best strategic mind of that generation, Zhuge Kongming, the Crouching Dragon.
