From what I understand, King Phillip's war against the New England colonies was maybe the most succesful undertaking of an Indian force against encroaching settlers. The tide was turned in 1676, when the Indians lost almost a thousand of their soldiers and then later lost their charismatic leader.
Had this not happened, it seems that Metacom's war may have lasted significantly longer. There's no way his 3500 or so warriors could have possibly won in the long-term against the English, but what if the war had dragged out another year, or maybe even two or three? The Indians would still take terrible losses, but the damage to property and loss of life among the colonists would be monumental, maybe even enough to discourage settlement in New England for several generations?
The following winter a thousand of the best men of New England marched against the savage foe; they surprised the Narragansett fort and put to death probably seven hundred people in a night. By the spring of 1676 the Indians were on the defensive. Philip became a fugitive and escaped his pursuers from place to place. At length he was overtaken in a swamp in <A href="http://www.usahistory.info/New-England/Rhode-Island.html">Rhode Island by Captain Ben Church of Plymouth and was shot dead by one of his own race.
