On the first of June, crossing Twelve-Mile River, Montgomerie began the campaign in earnest, devastating and burning every Indian village in the Valley of Keowee, killing and capturing more than a hundred of the Cherokees, and destroying immense stores of corn.

Receiving no reply to his summons to the Cherokees of the Middle and Upper Towns to make peace or suffer like treatment, Montgomerie took up his march from Fort Prince George on June 24th, resolved to carry out his threat.

On the morning of the 27th, he was drawn into an ambuscade within six miles of Et-chow-ee, eight miles south of the present Franklin, North Carolina, a mile and a half below Smith's Bridge, and was vigorously attacked from dense cover by some six hundred and thirty warriors led by Si-lou-ee.

Fighting with Indian tactics, the Provincial Rangers under Patrick Calhoun particularly distinguished themselves; and the bloodcurdling yells of the painted savages were responded to by the wild huzzas of the kilted Highlanders who, waving their Scotch bonnets, impetuously charged the redskins and drove them again and again from their lurking-places.

Nevertheless Montgomerie lost from eighty to one hundred in killed and wounded, while the loss of the Indians was supposed to be about half the loss of the whites.
Unable to care for his wounded and lacking the means of removing his baggage, Montgomerie silently withdrew his forces.
