The object of the expedition was accomplished. Thirty or forty of the warriors were slain; their stronghold was a smoking ruin. There was danger of the victors being cut off by a detachment from Fort Duquesne. They made the best of their way, therefore, to their horses, which had been left at a distance, and set off rapidly on their march to Fort Lyttleton, about sixty miles north of Fort Cumberland. Colonel Armstrong had reached Fort Lyttleton on the 14th of September, six days after the battle, and fears were entertained that he had been intercepted by the Indians and was lost. He, with his ensign and eleven men, had separated from the main body when they began their march, and had taken another and what was supposed a safer road. He had with him a woman, a boy, and two little girls, recaptured from the Indians. The whole party ultimately arrived safe at Fort Lyttleton, but it would seem that Mercer, weak and faint from his fractured arm, must have fallen behind, or in some way become separated from them, and had a long, solitary, and painful struggle through the wilderness, reaching the fort sick, weary, and half famished. [Footnote: "We hear that Captain Mercer was fourteen days in getting to Fort Lyttleton. He had a miraculous escape, living ten days on two dried clams and a rattlesnake, with the assistance of a few berries."--_New York Mercury for October_ 4, 1756.] We shall have to speak hereafter of his services when under the standard of Washington, whose friend and neighbor he subsequently became. [Footnote: Mercer was a Scotchman, about thirty-four years of age. About ten years previously he had served as Assistant Surgeon in the forces of Charles Edward, and followed his standard to the disastrous field of Culloden. After the defeat of the "Chevalier," he had escaped by the way of Inverness to America, and taken up his residence on the frontier of Pennsylvania.] CHAPTER XXI. FOUNDING OF FORT LOUDOUN--WASHINGTON'S TOUR OF INSPECTION--INEFFICIENCY OF THE MILITIA SYSTEM--GENTLEMEN SOLDIERS--CROSS-PURPOSES WITH DINWIDDIE-- MILITARY AFFAIRS IN THE NORTH--DELAYS OF LORD LOUDOUN--ACTIVITY OF MONTCALM--LOUDOUN IN WINTER QUARTERS. Throughout the summer of 1756, Washington exerted himself diligently in carrying out measures determined upon for frontier security. The great fortress at Winchester was commenced, and the work urged forward as expeditiously as the delays and perplexities incident to a badly organized service would permit. It received the name of Fort Loudoun, in honor of the commander-in-chief, whose arrival in Virginia was hopefully anticipated.
