Historical Information
Kenshin, taking the initiative moved to encircle Shigetsura’s forces preventing them from linking with the Oda army, and trapping Shigetsura in Anamizu Castle (the main Hatakeyama stronghold) the subsequent Breakthrough killed Shigetsura and resulted in the Hatakeyama switching allegiance to the Uesugi.

Due to the fall of Anamizu Castle the Oda army (now joined by Nobunaga himself) halted their march into Noto near the Tedori River and prepared to use cannons for stand-off tactics against the Uesugi. However a skillful nighttime feint by Kenshin (suggesting he had divided his forces) led to Nobunaga ordering Katsuie to charge against the Uesugi lines. Kenshin ordered the river’s floodgates to be opened. The strong current from the river prevented the Oda clan from effectively using its Arquebus and cannons. The Oda charge itself was repulsed due to the current and inferior close quarter ability of the ashigaru making up the bulk of the Oda army. Having suffered heavy casualties, Nobunaga ordered a retreat into Ōmi Province.
