Regarding Yoshiie's failure to be rewarded despite victory in the Later Three Years' War, engaging in battle without imperial consent was illegal at that time and an ambassador carrying the "Termination of the Battle at Oshu" order had been dispatched midway through the conflict.
尚、後三年の役の勝利にも関わらず恩賞が与えられなかった点に関しては、本来朝廷の命令（官符）無しに合戦を起こすことは当時でも違法行為であり、合戦の途中においても「奥州合戦停止」の官使の派遣を決定したりしている。
