| After returning from the [[Siege of Odawara|Siege of Odawara Castle]], Kenshin, the newly-minted Kanto Kanrei, immediately began planning another campaign, this one aimed at Shinano Province. Takeda Shingen’s northernmost fort was Kaizu, presently garrisoned by [[Kosaka Masanobu]] and a token force of cavalry. Kenshin set out with some 13,00 men under his command, intending apparently to provoke a major battle with Shingen. Here one must pause to consider that our only real source for the course of the following campaign is the Koyo Gunkan, a rambling and at times disjointed record of the Takeda family under Shingen. This was composed by Takeda partisans (Kosaka Masanobu himself is sometimes given as the composer but the actual author appears to have been [[Obata Kagenori]], [[1570]]-[[1644]]) and its accuracy is often dubious. But that having been said, the battle the Koyo Gunkan describes is the one imprinted in the minds of generations of Japanese. | | After returning from the [[Siege of Odawara|Siege of Odawara Castle]], Kenshin, the newly-minted Kanto Kanrei, immediately began planning another campaign, this one aimed at Shinano Province.
