M. de Contrecoeur, commandant of Fort du Quesne, had received information of all Braddock's movements from the Indians. With the view of embarrassing the English advance rather than of offering any serious resistance, he dispatched M. de Beaujeu, with 250 of the marine, or colony troops, toward the line of march which Braddock was expected to take; this detachment was afterward strengthened by about 600 Indians, principally Outamacs, and the united force took up a favorable position, where the underwood and long grass concealed them from the approaching enemy.
Intelligence of a contradictory nature as to the strength and movements of the French had been every day carried to the unfortunate Braddock by Indians professing to be his friends, and by doubly traitorous deserters. Still, under a fatal conviction of security, he had pursued his march, meeting with no interruption, except in taking "eight or nine scalps, a number much inferior to expectation." On the 8th of July, following the winding course which the difficulty of the country rendered necessary, he crossed the Monongahela River, encamped upon the bank at the opposite side from Fort du Quesne, and sent Sir John St. Clair forward to reconnoiter the enemy's fort. The quarter-master general was successful in attaining the desired information: he reported that the defenses were of timber, and that a small eminence lay close by, from whence red-hot shot could easily be thrown upon the wooden parapets.
At seven in the morning of the 9th of July, an advance guard of 400 men, under Colonel Gage, pushed on and took possession of the fords of the river, where it was necessary to recross, unopposed, but somewhat alarmed by the ominous appearance of a few Indians among the neighboring thickets. A little before mid-day the main body began to cross the broad stream with "colors flying, drums beating, and fifes playing the Grenadiers' March:" they formed rapidly on the opposite side, and, not having been interrupted in the difficult passage, recommenced their march in presumptuous security.
Three guides and six light horsemen led the way toward Fort du Quesne, through an open space in the forest, followed by the grenadiers of the 44th and 48th: flanking parties skirted the edge of the woods on both sides. The 44th regiment succeeded with two guns; behind them were the 48th, with the rest of the artillery and the general: the Virginian companies, in unwilling obedience, sullenly brought up the rear. In this order they advanced with as much regularity as the rough road permitted. When within seven miles of the fort, they left a steep conical hill to the right, and directed their march upon the extremity of the open space, where the path disappeared between the thickly-wooded banks of a small brook: so far all went well.
