Nothing was done to annoy the French or check the Indians, until a change occurred in the English Ministry, and the master mind of William Pitt assumed the control of the mother country. He seemed to fully realize the situation of the English subjects in the colonies and immediately determined to send troops in sufficient strength to maintain her power.
Pennsylvania, as usual, led the way and equipped 2700 men. The other colonies contributed large quotas.
Three expeditions were determined upon, and the most active measures taken to bring them to the field. The one in which Pennsylvanians are more properly interested was known as the Western expedition. It was placed under the command of Major General John Forbes, an officer of great skill, energy and resolution. His army consisted of nearly 9000 men, embracing British regulars and provincials from Pennsylvania, and the Lower Counties, Virginia, Maryland and North Carolina.
The troops from the other Governments rendezvoused at Winchester, while the Pennsylvanians, under Colonel Henry Bouquet, assembled at Raystown, now Bedford.
General Forbes, with his regulars, marched from Philadelphia to effect a junction with the provincials at Raystown, but the serious illness of the general compelled him to stop at Carlisle, where he remained until the middle of September, when he reached Bedford and the provincial troops under Colonel George Washington.
At the suggestion of Colonel Bouquet and the Pennsylvania officers, a new road was cut direct from Raystown to Loyalhanna, a distance of forty-five miles, where Colonel Bouquet erected Fort Ligonier.
Before the arrival of General Forbes at Loyalhanna, Colonel Bouquet had dispatched Major William Grant, of the Highland Regiment, with thirty-seven officers and 800 troops, to reconnoitre the fort and adjacent country. His instructions were to approach not too near the fort, and in no event to take the risk of an attack.
Grant camped the first day on the banks of the Nine Mile Run, ten miles west of the camp on the Loyalhanna. The second day he proceeded farther, and on the third reached to within about twelve miles of Fort Duquesne.
Although the French and Indians were constantly watching the movements of the army, yet Grant succeeded in coming within sight of the fort, after marching fifty miles without being discovered.
The detachment halted here until 3 o’clock in the afternoon, when the troops quietly marched to about two miles from the fort, where they left their baggage under charge of Captain Bullitt, two subalterns and fifty men. It was already dark, and later in the night Major Grant appeared with his troops at the brow of the fatal hill, which still bears his name, between the two rivers, about a quarter of a mile from the fort.
