 Officers of the Westmoreland Militia met on June 18, 1781, at the home of Captain John McClelland, on Big Sewickley Creek, and by a majority, voted to give aid to General George Rogers Clark.It was resolved to furnish 300 men out of the County Militia to join General Clark's army against the Ohio savages, for the immediate benefit of the Westmoreland frontier; despite the fact that Clark's real intention was to conquer the British post at Detroit.Although George Washington agreed to transfer a small group of regulars to assist Clark, the detachment was defeated in August 1781 before they could meet up with Clark, effectively putting an end to the campaign.
