In the year 1643, Miantonimoh invaded the Mohegans with nine hundred of his warriors; Uncas met him at the head of five hundred of his men, on a large plain; both prepared for action, and advanced within bow-shot. Before the conflict commenced, Uncas advanced singly, and thus addressed his antagonist: "You have a number of men with you, and so have I with me. It is a pity that such brave warriors should be killed in a private quarrel between us. Come like a man, as you profess to be, and let us fight it out. If you kill me, my men shall be yours; but if I kill you, your men shall be mine." Miantonimoh replied: "My men came to fight, and they shall fight." Uncas had before told his men, that if his enemy should refuse to fight with him personally, he would fall down, and then they were to discharge their missiles on the Narragansets, and fall upon them as fast as they could. This was accordingly done. Uncas instantly fell upon the ground, and his men poured a shower of arrows upon Miantonimoh's army, and with a horrible yell advanced rapidly upon them, and put them to flight. Uncas and his men pressed on, driving them down ledges of rock, and scattering them in every direction. Miantonimoh was overtaken and seized by Uncas, who, by a shout, called back his furious warriors. About thirty Narragansets were slain, among whom were several noted chiefs. Finding himself in the hands of his implacable enemy, Miantonimoh remained silent, nor could Uncas, by any art, force him to break his sullen mood. "Had you taken me," said the conqueror, "I should have asked you for my life." No reply was made by the indignant chief, and he submitted without a murmur to his humiliating condition. He was afterwards conducted to Hartford, by his conqueror, and delivered to the English, by whom he was held in duress until his fate should be determined by the commissioners of the colonies. After an examination of his case, the commissioners resolved, "that as it was evident that Uncas could not be safe while Miantonimoh lived, but either by secret treachery or open force his life would be constantly in danger, he might justly put such a false and blood-thirsty enemy to death; but this was to be done out of the English jurisdiction, and without cruelty or torture." Miantonimoh was delivered to Uncas, and by a number of his trusty men was marched to the spot where he was captured, attended by two Englishmen to see that no torture was inflicted, and the moment he arrived at the fatal place, one of Uncas' men came up behind, and with his hatchet split the skull of the unfortunate chief. The body was buried on the spot, and a heap of stones piled upon the grave. The place since that time has been known by the name of Sachem's plain, and is situated in the town of Norwich, in Connecticut.[20]

The Narragansets, as was to be expected, ever afterwards bore an implacable malice against Uncas and all the Mohegans, and also for their sakes secretly against the English, so far as they dared to discover it. But the death of Miantonimoh, and the preparation for the invasion of the Narraganset country by the English which had been made, put an end to hostilities for a period in the eastern part of Connecticut.

In continuing the Narraganset history, Ninigret now properly comes into view. As already mentioned, he was sachem of the Nianticks, a tribe of the Narragansets. In 1644, the Narragansets and Ninigret's men united against the Mohegans, and for some time obliged Uncas to confine himself and men to his fort. The Indians, however, afraid of the English, abandoned the siege, and came in to Boston to sue for peace. This was granted; but a short time after, it became necessary to again terrify them. With twenty men, Captain Atherton marched to the wigwam of Ninigret, entering which, he seized the chief, and threatened his life. This step had the desired effect. The Indians begged for life, and promised submission.

Some time after this occurrence, Ninigret again grew troublesome, and again had to be quieted by an armed force sent against him. In the panic with which he was affected, he submitted to the demands that were laid upon him. Ninigret passed the winter of 1652-53 among the Dutch of New York. This circumstance awakened the suspicions of the English, especially as hostile feelings existed at that time between the Dutch and English. The report from several sagamores was, that the Dutch governor had attempted to hire them to cut off the English. The consequence was, a special meeting of the English commissioners of the several New England colonies, to consult in reference to this subject. Their object was to ascertain the truth of the rumor, that the Narragansets had leagued with the Dutch, to break up the English settlements. Several of the chiefs of the Narragansets were accordingly questioned by a letter, through an agent living at the Narraganset, in regard to this plot; but their answers were altogether exculpatory. As to any positive testimony that Ninigret was plotting against the English, there appears to be none.

In the year 1652, a war having commenced between England and Holland, it was apprehended that hostilities would take place between the colonies of the two nations in America. A threatening attitude was indeed held for some time by the Dutch of New Netherlands, and forces were raised by the four New England colonies; but no collision occurred. In the event of hostilities, it was believed that the sachem, Ninigret, would lead the Narragansets to the aid of the Dutch, and that he had held a conference with them at Manhattan, in the winter of 1652. Whether that was the case or not, he refused for some time after to treat with the English for a continuance of the peace. Under these threatening appearances, the commissioners of the colonies met, and resolved to raise two hundred and seventy infantry, and forty cavalry, for the purpose of chastising Ninigret's haughtiness, and bringing the Narragansets to terms. The forces were duly apportioned among the colonies. Massachusetts had been at first reluctant, but finally assented to the measure. The commissioners nominated Major Gibbons, Major Denison, or Captain Atherton, to the chief command; leaving it, in complaisance, to the general court of Massachusetts to appoint which one of the three they should please. But, rejecting these, who were men of known courage and enterprise, they appointed Major Simon Willard. The commissioners instructed him to proceed, with such troops as should be found at the place of general rendezvous, by the 13th of October, directly to Ninigret's quarters, and demand of him the Pequods who had been put under him, and the tribute which was due. If Ninigret should not deliver them, and pay the tribute, he was required to take them by force. He was instructed to demand of the sachem a cessation from all further hostilities against the Long Island Indians. Receiving these and some other instructions, he proceeded into the Narraganset country. When he arrived at the place of rendezvous, he found that Ninigret had fled into a swamp about fifteen miles distant. The latter had left his country, corn, and wigwams, without defence, and they might have been laid waste without danger or loss. He, however, returned without ever advancing from his head-quarters, or doing the enemy the least damage. About a hundred Pequods took this opportunity to renounce the government of Ninigret, and come off with the English army, putting themselves under the control of the whites.

The commissioners in favor of the expedition, were dissatisfied with the conduct of Major Willard, and charged him with having neglected a fair opportunity of chastising the Indians, by the destruction of their dwellings, and their fields of corn. He, however, pleaded in excuse, that his instructions were equivocal, and the season for marching unfavorable. By many people in Connecticut and New Haven, it was believed that the commander was secretly instructed by the government of Massachusetts to avoid depredations on the property of the Indians, and thereby prevent a war, which the latter colony considered to be of doubtful policy. However this may be, it is certain that Major Willard received no censure from the Massachusetts court, and no one doubted his firmness as an officer.

After the return of the English troops from the Narraganset country, Ninigret assumed his former spirit of defiance, and continued the war against the Indians upon Long Island. Both the Indians and the English there were soon thrown into great distress. It became apparent that these Indians could not hold out much longer, but that they must submit themselves and their country to the Narragansets, unless they should receive speedy aid. In consequence of this state of things, and as these Indians were in alliance with the colonies, measures were taken to aid them against Ninigret. An armed vessel was stationed off Montauk to watch his movements, and forces were held in readiness at Saybrook and New London, to move on the shortest notice, should the hostile chief again attempt to invade the island. Hostilities, however, continued some time, and the tribes in various directions exhibited a strange, changeable conduct. Uncas, in this exigency, was so pressed by the Narragansets, that Connecticut was obliged to send men to his fortress to assist in defending himself against them. The Narragansets, in several instances, threatened and plundered the inhabitants of Connecticut.
