When Major Grant with his men had been ordered on to Du Quesne, the main army had been left at Raystown, where it continued for some time; an advance was however posted at fort Ligonier. Between this vanguard and the detachment from Du Quesne there was a partial engagement, which resulted in the loss of some of the Maryland troops. Fort Ligonier was then closely watched by the French and Indians, and several of the sentinels were killed, before the point from which the fires were directed, was discovered; it was at length ascertained that parties of the enemy would creep under the bank of the Loyal Hanna till they could obtain a position from which to do execution. Some soldiers were then stationed to guard this point, who succeeded in killing two Indians, and in wounding and making prisoner of one Frenchman. From him the English obtained information that the greater part of the Indians had left Du Quesne, and that the fort was defenceless: the army then moved forward and taking possession of its ruins established thereon Fort Pitt.[13] The country around began immediately to be settled, and several other forts were erected to protect emigrants, and to keep the Indians in awe.
Previous to this an attempt had been made by David Tygart and a Mr. Files to establish themselves on an upper branch of the Monongahela river.[14] They had been for some time frontier's men, and were familiar with the scenes usually exhibited on remote and unprotected borders; and nothing daunted by the cruel murders and savage enormities, which they had previously witnessed, were induced by some cause, most probably the uninterrupted enjoyment of the forest in the pursuit of game, to venture still farther into the wilderness. About the year 1754 these two men with their families arrived on the east fork of the Monongahela, and after examining the country, selected positions for their future residence. Files chose a spot on the river, at the mouth of a creek which still bears his name, where Beverly, the county seat of Randolph has been since established. Tygart settled a few miles farther up and also on the river. The valley in which they had thus taken up their abode, has been since called Tygart's [59] valley, and the east fork of the Monongahela, Tygart's-valley river.
