It was in the main observed by the Narragansets. They allowed the colonial army to pass through their territories, and furnished five hundred men for the war.
Uncas, the chief of the Mohegans, had also been an ally of the English against the Pequots. After the destruction of this tribe, the three parties declared a peace, and the spoils of the war were divided between the allies. But the Narragansets and Mohegans were naturally enemies. The latter were of the Pequot race, and Uncas himself, having married the daughter of Sassacus, was but a revolted subject of that great chief. It is said that one of Uncas' dependent sachems attacked Miantonomo, who referred the matter to the English and was told to take his own course, and invaded the Mohegan country with a thousand warriors. The fortunes of war were against him and he fell into the hands of Uncas. The victor now referred the fate of his victim to the English. They decided that the rules of war permitted, and the safety of Uncas required, the death of Miantonomo. They were careful, however, not to permit his execution within their jurisdiction. The colonies were responsible for the death of this chief. Uncas was nominally their ally, but really their subject. From first to last he did their bidding with a spirit so craven and a manner so treacherous that he was neither trusted nor respected by them. But the English in their death-warrant voluntarily offered to protect Uncas from the consequences of Miantonomo's death. This was in 1643, and thus did the English observe the treaty of peace made seven years before under circumstances of extraordinary solemnity. Miantonomo died the victim of rivalry, jealousy and fear, yet with a spirit so heroic that he scorned to ask the precious boon of life from those whom he had served rather than wronged. His death was the seed of the war of 1675, —for how, under these circumstances, could Canonchet, his son and successor, be other than the enemy of the English, the ready and efficient ally of Philip.
But aside from particular incidents in the relations of the English to the Indians there were three ever-operating causes of hostility.
1st. The mutual disposition of the English and the Indians to traffic with each other. The colonies passed the most stringent laws for the suppression of this traffic, or to make it a monopoly in their own hands, and the government at home issued two or more proclamations. These laws and proclamations had no great practical value, and the Indians were constantly supplied with spirits, clothing, munitions and weapons of war, either by the English, French, or Dutch. Thus trade furnished an occasion for hostility, and the means of gratifying the spirit of war.
2nd. There was a universal tendency in the people and governments of the colonies to acquire land.
There was, however, a settled purpose on the part of the company in England and the governments here to make this spirit conform to the principles of honor and justice. In the company's letter of instruction of April 17, 1629, Endicott and his Council were told that "If any of the savages pretend right of inheritance to all or any part of the lands granted in our patent, we pray you to endeavor to purchase their title, that we may avoid the least scruple of intrusion." And in a second letter of the 28th of May following, the same injunction is imposed upon the settlers. Attempts were made to pursue the course pointed out by the company, and a penalty of five pounds per acre was imposed upon any person who should receive an Indian title without the consent of the government. Governor Winslow, in 1676, writes thus: "I think I can clearly say, that before the present trouble broke out, the English did not possess one foot of land in this colony but what was fairly obtained by honest purchase of the Indian proprietors."
It is no doubt true that for the most part the lands were purchased, and, according to the idea of the English, honorably purchased, yet the natives could not fail to foresee the result of these cessions of territory. There were English settlements at Bridgewater, Middleboro', Taunton, Rehoboth, Seekonk, and Swanzey, all within the ancient jurisdiction of Massasoit. And as a perpetual monitor to Philip of his limited domains, though in obedience to a different and highly honorable motive, the people erected a fence quite across the neck of land on the south of Swanzey, and thus confined the Pokanokets by metes and bounds.
That Philip was annoyed by applications for land is evident from his letter, without date, addressed to Governor Prince of Plymouth:
"Philip would intreat that favor of you, and any of the magistrates, if any English or Indians speak about any land, he pray to give them no answer at all. This last summer he made that promise with you, that he would sell no land in seven years' time, for that he would have no English trouble him before that time. He has not forgot that you promise him."
The apostle Eliot, in a letter to the Massachusetts government, dated in 1684, asking that certain fraudulent purchases of the Indians might be annulled, puts this suggestive inquiry: "Was not a principal cause of the late war about encroachments on Philip's land at Mount Hope?"
