The darkest blot upon the character of Yoritomo is his treatment of his youngest brother Yoshitsuné. It was he who had by his generalship and gallantry brought these terrible wars to a triumphant conclusion. He had crushed in the decisive battle of Dan-no-ura the last of the enemies of Yoritomo. With his victorious troops he marched northward, and with prisoners and captured standards was on his way to lay them at the feet of his now triumphant brother at Kamakura. But the demon of jealousy had taken possession of Yoritomo. He resented the success and fame of his more winning and heroic brother. He sent orders to him not to enter Kamakura, and to give up his trophies of battle at Koshigoye near to Enoshima. Here at the monastery of Mampukuji is still kept the draft of the touching letter(120) which he sent to his brother, protesting his loyalty and denying the charges of ambition and self-seeking which had been made against him. But all this availed nothing. Yoshitsuné returned to Kyōto and, in fear of bodily harm from the machinations of his brother, made his escape with his faithful servant Benkei,(121) into his old asylum with his friend Fujiwara Hidehira the governor of Mutsu. Shortly after his arrival, however, Hidehira died, and his son Yasuhira abjectly connived at his assassination(122) A.D. 1189, with a view to secure Yoritomo’s favor. He was at the time of his death only thirty years of age. He has lived down to the present time in the admiring affection of a warlike and heroic people. Although Yoritomo is looked upon as perhaps their greatest hero, yet their admiration is always coupled with a _proviso_ concerning his cruel treatment of his brother. In order not to rest under the imputation of having encouraged this assassination, Yoritomo marched at the head of a strong force and inflicted punishment upon Yasuhira for having done what he himself desired but dared not directly authorize. The way was now clear for Yoritomo to establish a system of government which should secure to him and his family the fruits of his long contest. In A.D. 1190, he went up to the capital to pay his respects to the Emperor Go-Toba as well as to the veteran retired Emperor Go-Shirakawa. The latter was now in his sixty-sixth year, and had held his place through five successive reigns, and was now the friend and patron of the new government. He died, however, only two years later. Yoritomo knew the effect produced by a magnificent display, and therefore made his progress to the capital with all the pomp and circumstance which he could command. The festivities were kept up for a month, and the court and its surroundings were deeply impressed with a sense of the power and irresistible authority of the head of the Minamoto clan.
