"The trouble with Yamanami seems to have originated over a disagreement in philosophy, though Shimosawa also cites a bitter rivalry with the other vice commander, Hijikata Toshizo. Yamanami was apparently vexed over the lately inflated self-importance of Kondo and Hijikata. He felt that they had forgotten the original purpose for which the members of the Shieikan had enlisted in the "loyal and patriotic" corps. The unyielding will to power that had lately consumed his erstwhile friends had diminished their former patriotic ideals. According to most sources, Yamanami's vexation was exacerbated sometime early in 1865, when Kondo and Hijikata, unhappy with their cramped headquarters at Mibu, decided to move to a more spacious location at Nishihonganji Temple in the southwest of the city. The temple priests were perplexed over the decision. Their attempts to rebuff the Shinsengumi were ignored by Kondo and Hijikata. Yamanami objected to what he considered coercion of Buddhist priests. "Certainly there are many other suitable places, " he admonished Kondo, and suggested that his commander reconsider. But his commander would not reconsider, and Yamanami resolved to pay the ultimate price. He composed a farewell letter explaining the reasons he could no longer, in good conscience, risk his life under Kondo's command. Then he defected."
