The true reason why the enemy did not pursue the retreating army was not known until some time afterwards, and added to the disgrace of the defeat. They were not the main force of the French, but a mere detachment of 72 regulars, 146 Canadians, and 637 Indians, 855 in all, led by Captain de Beaujeu. De Contrecoeur, the commander of Fort Duquesne, had received information, through his scouts, that the English, three thousand strong, were within six leagues of his fort. Despairing of making an effectual defence against such a superior force, he was balancing in his mind whether to abandon his fort without awaiting their arrival, or to capitulate on honorable terms. In this dilemma Beaujeu prevailed on him to let him sally forth with a detachment to form an ambush, and give check to the enemy. De Beaujeu was to have taken post at the river, and disputed the passage at the ford. For that purpose he was hurrying forward when discovered by the pioneers of Gage's advance party. He was a gallant officer, and fell at the beginning of the fight. The whole number of killed and wounded of French and Indians, did not exceed seventy. Such was the scanty force which the imagination of the panic-stricken army had magnified into a great host, and from which they had fled in breathless terror, abandoning the whole frontier. No one could be more surprised than the French commander himself, when the ambuscading party returned in triumph with a long train of packhorses laden with booty, the savages uncouthly clad in the garments of the slain, grenadier caps, officers' gold-laced coats, and glittering epaulettes; flourishing swords and sabres, or firing off muskets, and uttering fiendlike yells of victory. But when De Contrecoeur was informed of the utter rout and destruction of the much dreaded British army, his joy was complete. He ordered the guns of the fort to be fired in triumph, and sent out troops in pursuit of the fugitives. The affair of Braddock remains a memorable event in American history, and has been characterized as "the most extraordinary victory ever obtained, and the farthest flight ever made." It struck a fatal blow to the deference for British prowess, which once amounted almost to bigotry, throughout the provinces. "This whole transaction," observes Franklin, in his autobiography, "gave us the first suspicion, that our exalted ideas of the prowess of British regular troops had not been well founded."
