When he reached this fortress, he received intelligence that the enemy had entered the pass of Killycrankie, and he resolved to give them battle without delay.

He accordingly advanced against them, and a furious engagement ensued, though it was not of long duration.

The Highlanders having received and returned the fire of the English, fell in among them sword in hand with such impetuosity, that the foot were utterly broke in seven minutes.

The dragoons fled at the first charge in the utmost consternation.

Dundee's horse, not exceeding one hundred, broke through Mackay's own regiment; the earl of Dumbarton, at the head of a few volunteers, made himself master of the artillery: twelve hundred of Mackay's forces were killed on the spot, five hundred taken prisoners, and the rest fled with great precipitation for some hours, until they were rallied by their general, who was an officer of approved courage, conduct, and experience.
