In old Japan more than seven hundred years ago a fierce war was raging between the two great clans, the Taira and the Minamoto, also called the Heike and the Genji. These two famous clans were always contesting together for political power and military supremacy, and the country was torn in two with the many bitter battles that were fought. Indeed it may be said that the history of Japan for many years was the history of these two mighty martial families; sometimes the Minamoto and sometimes the Taira gaining the victory, or being beaten, as the case might be; but their swords knew no rest for a period of many years. At last a strong and valiant general arose in the House of Minamoto. His name was Yoshitomo. At this time there were two aspirants for the Imperial throne and civil war was raging in the capital. One Imperial candidate was supported by the Taira, the other by the Minamoto. Yoshitomo, though a Minamoto, sided at first with the Taira against the reigning Emperor; but when he saw how cruel and relentless their chief, Kiyomori, was, he turned against him and called all his followers to rally round the Minamoto standard and fight to put down the Taira.

But fate was against the gallant and doughty warrior Yoshitomo, and he suffered a crushing defeat at the hands of the Taira. He and his men, while fleeing from the vigilance of their enemies, were overtaken within the city gates, and ruthlessly slaughtered by Kiyomori and his soldiers.

Yoshitomo left behind him his beautiful young wife, Tokiwa Gozen, and eight children, to mourn his untimely death. Five of the elder children were by a first wife. The third of these became Yoritomo, the great first Shogun of Japan, while the eighth and youngest child was Ushiwaka, about whom this story is written. Ushiwaka and the hero Yoshitsune were one and the same person. Ushiwaka (Young Ox—he was so called because of his wonderful strength) was his name as a boy, and Yoshitsune was the name he took when he became of age.

At the time of his father's death, Ushiwaka was a babe in the arms of his mother, Tokiwa Gozen, but his tender age would not have saved his life had he been found by his father's enemies.

After the defeat they had inflicted on the rival clan, the Taira were all-powerful for a time. The Minamoto clan were in dire straits and in danger of being exterminated now, for so fierce was Kiyomori's hatred against his enemies that when a Minamoto fell into his cruel hands he immediately put the captive to death.

Realizing the great peril of the situation, Tokiwa Gozen, the widow of Yoshitomo, full of fear and anxiety for the safety of her little ones, quietly hid herself in the country, taking with her Ushiwaka and her two other children. So successful was Tokiwa Gozen in concealing her hiding-place that, though the Taira clan either killed or banished to a far-away island all the elder sons, relations, and partisans of the Minamoto chief, they could not discover the whereabouts of the mother and her children, notwithstanding the strict search Kiyomori had made.

Determined to have his will, and angry at being thwarted by a woman, Kiyomori at last hit on a plan which he felt sure would not fail to draw the wife of Yoshitomo from her hiding-place. He gave orders that Sekiya, the mother of the fair Tokiwa, should be seized and brought before him. He told her sternly that if she would reveal her daughter's hiding-place she should be well treated, but if she refused to do as she was told she would be tortured and put to death. When the old lady declared that she did not know where Tokiwa was, as in truth she did not, Kiyomori thrust her into prison and had her treated cruelly day after day.

Now the reason why Kiyomori was so set on finding Tokiwa and her sons was that while Yoshitomo's heirs lived he and his family could know no safety, for the strongest moral law in every Japanese heart was the old command, "A man may not live under the same heaven with the murderer of his father," and the Japanese warrior recked nothing of life or death, of home or love in obeying this—as he deemed—supreme commandment. Women too burned with the same zeal in avenging the wrongs of their fathers and husbands.

Tokiwa Gozen, though hiding in the country, heard of what had befallen her mother, and great was her sorrow and distress. She sat down on the mats and moaned aloud: "It is wrong of me to let my poor innocent mother suffer to save myself and my children, but if I give myself up, Kiyomori will surely take my lord's sons and kill them.—What shall I do? Oh! what shall I do?"

Poor Tokiwa! Her heart was torn between her love for her mother and her love for her children. Her anxiety and distraction were pitiful to see. Finally she decided that it was impossible for her to remain still and silent under the circumstances; she could not endure the thought that her mother was suffering persecution while she had the power of preventing it, so holding the infant Ushiwaka in her bosom under her kimono, she took his two elder brothers (one seven and the other five years of age) by the hand and started for the capital.
