His army was seventy-five thousand strong. That opposed to him exceeded his in strength by more than fifty thousand men. But neither as yet knew what they had to encounter, for a fog lay heavy on the plain, and the two armies, drawn up in battle array, were invisible to each other. To prevent surprise, Iyeyasu sent in front of his army a body of guards bearing white flags, to give quick warning of an advance.
At length, at eight o'clock, the fog rose and drifted away, revealing the embattled hosts. Hardly had it vanished before the drums beat their battle peal and the martial conchs sounded defiance, while a shower of arrows from each army hurtled through the opposing ranks. In a short time the impatient warriors met in mid field, and sword and spear began their deadly work.
The great weight of the army of the league at first gave it the advantage, and for hours the result was in doubt, though a corps of the league forces deserted to the ranks of Iyeyasu. At length unity and discipline began to prevail, the intrepidity of Iyeyasu and his skill in taking advantage of every error of his enemy giving confidence to his men. By noon they were bearing back the foe. Ordering up the reserves, and bidding the drummers and conch-blowers to sound their most inspiriting appeal, Iyeyasu gave order for the whole army to charge.
Before the impetuous onset that followed, the enemy wavered, broke, and fled, followed in hot pursuit by the victorious host. And now a frightful scene began. Thousands of heads of the flying were cut off by the keen-edged blades of their pursuers. Most of the wounded and many of the unhurt killed themselves upon the field, in obedience to the exaggerated Japanese sense of honor. The defeat became a butchery. In Japanese battles of the past quarter was a mercy rarely craved or granted, and decapitation the usual mode of death when the sword could be brought into play, so that the triumph of the victors was usually indicated by the dimensions of the ghastly heap of heads. In this frightful conflict the claim was made by the victors (doubtless an exaggeration) that they had taken forty thousand heads of the foe, while their own loss was only four thousand. However that be, a great mound of heads was made, one of many such evidences of slaughter which may still be seen in Japan.
Throughout the battle a knotted handkerchief was the only defence of Iyeyasu's head. The victory won, he called for his helmet, which he put on, carefully tying the strings. As all looked on with surprise at this strange action, he, with a smile, repeated to them an old Japanese proverb, "After victory, knot the cords of your helmet."
It was a suggestion of vigilance wisely given and alertly acted upon. The strongholds of the league were invested without delay, and one by one fell into the victors' hands. The fragments of the beaten army were followed and dispersed. Soon all opposition was at an end, and Iyeyasu was lord and master of Japan.
The story of the victor in the most decisive victory Japan had ever known, one that was followed by two and a half centuries of peace, needs to complete it a recital of two important events, one being the founding of Yedo, the great eastern capital, the other the organization of the system of feudalism.
For ages the country around the Bay of Yedo, now the chief centre of activity and civilization in Japan, was wild and thinly peopled. The first mention of it in history is in the famous march of Yamato-Daké, whose wife leaped here into the waves as a sacrifice to the maritime gods. In the fifteenth century a small castle was built on the site of the present city, while near it on the Tokaida, the great highway between the two ancient capitals, stood a small village, whose chief use was for the refreshment and assistance of travellers.
Ota Dagnan, the lord of the castle, was a warrior of fame, whose deeds have gained him a place in the song and story of Japan. Of the tales told of him there is one whose poetic significance has given it a fixed place in the legendary lore of the land. One day, when the commandant was amusing himself in the sport of hawking, a shower of rain fell suddenly and heavily, forcing him to stop at a house near by and request the loan of a grass rain-coat,—a mino, to give it its Japanese name.
A young and very pretty girl came to the door at his summons, listened to his polite request, and stood for a moment blushing and confused. Then, running into the garden, she plucked a flower, handed it with a mischievous air to the warrior, and disappeared within the house. Ota, angrily flinging down the flower, turned away, after an impulse to force his way into the house and help himself to the coat. He returned to the castle wet and fuming at the slight to his rank and dignity.
