Between January and February 1812, he made strenuous exertions and shut himself up at a temporary residence of Naofuru SHIBASAKI, a disciple in Fuchu, Suruga Province, and he at once finished writing several books about Kodai Kenkyu (Ancient Study), including "Koshiseibun", "Koshicho" (Clarification of Early History) and "Koshiden" (Commentary on Ancient History).

今般、河野主一郎、山野田一輔の両士を敵陣に遣はし候儀、全く味方の決死を知らしめ、且つ義挙の趣意を以て、大義名分を貫徹し、法庭に於て斃れ候賦（つもり）に候間、一統安堵致し、此城を枕にして決戦可致候に付、今一層奮発し、後世に恥辱を残さざる様、覚悟肝要に可有之候也。

This time, having sent Shuichiro Kono and Kazusuke Yamanoda to the enemy camp, I intend to make known our resolve to die for our side, to carry through our just cause, and to fall in court; rest assured, make further efforts to fight to the death in this castle, and resolve not to leave disgrace to posterity.
