Oda Nobunaga, who would do more to unite Japan than any before him, was almost nipped at the bud. During his invasion of the Azai he fought the combined Azai/Asakura Army at Anegawa River. Oda's forces were almost routed and Oda himself was almost killed, only to be saved at the last moment. The Battle was only salvaged when Tokugawa routed the Asakura force and slammed into the Azai flank. Let's say that Tokugawa takes longer and Oda's forces break. What happens next?
