At length the army arrived in sight of Fort Duquesne, advancing with great precaution, and expecting a vigorous defence; but that formidable fortress, the terror and scourge of the frontier, and the object of such warlike enterprise, fell without a blow. The recent successes of the English forces in Canada, particularly the capture and destruction of Fort Frontenac, had left the garrison without hope of reinforcements and supplies. The whole force, at the time, did not exceed five hundred men, and the provisions were nearly exhausted. The commander, therefore, waited only until the English army was within one day's march, when he embarked his troops at night in batteaux, blew up his magazines, set fire to the fort, and retreated down the Ohio, by the light of the flames. On the 25th of November, Washington, with the advanced guard, marched in, and planted the British flag on the yet smoking ruins. One of the first offices of the army was to collect and bury, in one common tomb, the bones of their fellow-soldiers who had fallen in the battles of Braddock and Grant. In this pious duty it is said every one joined, from the general down to the private soldier; and some veterans assisted, with heavy hearts and frequent ejaculations of poignant feeling, who had been present in the scenes of defeat and carnage. The ruins of the fortress were now put in a defensible state, and garrisoned by two hundred men from Washington's regiment; the name was changed to that of Fort Pitt, in honor of the illustrious British minister, whose measures had given vigor and effect to this year's campaign; it has since been modified into Pittsburg, and designates one of the most busy and populous cities of the interior. The reduction of Fort Duquesne terminated, as Washington had foreseen, the troubles and dangers of the southern frontier. The French domination of the Ohio was at an end; the Indians, as usual, paid homage to the conquering power, and a treaty of peace was concluded with all the tribes between the Ohio and the lakes. With this campaign ended, for the present, the military career of Washington. His great object was attained, the restoration of quiet and security to his native province; and, having abandoned all hope of attaining rank in the regular army, and his health being much impaired, he gave up his commission at the close of the year, and retired from the service, followed by the applause of his fellow-soldiers, and the gratitude and admiration of all his countrymen. His marriage with Mrs. Custis took place shortly after his return. It was celebrated on the 6th of January, 1759, at the White House, the residence of the bride, in the good old hospitable style of Virginia, amid a joyous assemblage of relatives and friends.
