Since the article dated May 4, 1213, of "Azuma Kagami" says 'Yamashiro hangan Yukimura was a bugyo (magistrate) and Yukichika and Tadaie supported him', in the Battle of WADA, it is considered that Yukimura was a military commissioner for Hojo and most descriptions of the Battle of WADA in "Azuma Kagami" were based on the historical documents compiled by Yukimura.
和田合戦では『吾妻鏡』1213年（建暦3年）5月4日条に「山城判官行村奉行たり、行親・忠家これを相副う」とあり、行村が北条方の軍奉行とみて間違いないだろうとされ、『吾妻鏡』の和田合戦の多くは行村が取り纏めた史料によると見られている。
