The manner in which Washington was received by Lord Loudoun on arriving in Philadelphia, showed him at once, that his long, explanatory letter had produced the desired effect, and that his character and conduct were justly appreciated. During his sojourn in Philadelphia he was frequently consulted on points of frontier service, and his advice was generally adopted. On one point it failed. He advised that an attack should be made on Fort Duquesne, simultaneous with the attempts on Canada. At such time a great part of the garrison would be drawn away to aid in the defence of that province, and a blow might be struck more likely to insure the peace and safety of the southern frontier, than all its forts and defences.
Lord Loudoun, however, was not to be convinced, or at least persuaded. According to his plan, the middle and southern provinces were to maintain a merely defensive warfare; and as Virginia would be required to send four hundred of her troops to the aid of South Carolina, she would, in fact, be left weaker than before.
Washington was also disappointed a second time, in the hope of having his regiment placed on the same footing as the regular army, and of obtaining a king's commission; the latter he was destined never to hold.
His representations with respect to Fort Cumberland had the desired effect in counteracting the mischievous intermeddling of Dinwiddie. The Virginia troops and stores were ordered to be again removed to Fort Loudoun, at Winchester, which once more became head-quarters, while Fort Cumberland was left to be occupied by a Maryland garrison. Washington was instructed, likewise, to correspond and co-operate, in military affairs, with Colonel Stanwix, who was stationed on the Pennsylvania frontier, with five hundred men from the Royal American regiment, and to whom he would be, in some measure, subordinate. This proved a correspondence of friendship, as well as duty; Colonel Stanwix being a gentleman of high moral worth, as well as great ability in military affairs.
The great plan of operations at the north was again doomed to failure. The reduction of Crown Point, on Lake Champlain, which had long been meditated, was laid aside, and the capture of Louisburg substituted, as an acquisition of far greater importance. This was a place of great consequence, situated on the isle of Cape Breton, and strongly fortified. It commanded the fisheries of Newfoundland, overawed New England, and was a main bulwark to Acadia.
In the course of July, Lord Loudoun set sail for Halifax with all the troops he could collect, amounting to about six thousand men, to join with Admiral Holbourne, who had just arrived at that port with eleven ships of the line, a fire-ship, bomb-ketch, and fleet of transports, having on board six thousand men. With this united force Lord Loudoun anticipated the certain capture of Louisburg.
Scarce had the tidings of his lordship's departure reached Canada, when the active Montcalm again took the field, to follow up the successes of the preceding year. Fort William Henry, which Sir Wm. Johnson had erected on the southern shore of Lake George, was now his object; it commanded the lake, and was an important protection to the British frontier. A brave old officer, Colonel Monro, with about five hundred men, formed the garrison; more than three times that number of militia were intrenched near by. Montcalm had, early in the season, made three ineffectual attempts upon the fort; he now trusted to be more successful. Collecting his forces from Crown Point, Ticonderoga, and the adjacent posts, with a considerable number of Canadians and Indians, altogether nearly eight thousand men, he advanced up the lake, on the 1st of August, in a fleet of boats, with swarms of Indian canoes in the advance. The fort came near being surprised; but the troops encamped without it, abandoned their tents and hurried within the works. A summons to surrender was answered by a brave defiance. Montcalm invested the fort, made his approaches, and battered it with his artillery. For five days its veteran commander kept up a vigorous defence, trusting to receive assistance from General Webb, who had failed to relieve Fort Oswego in the preceding year, and who was now at Fort Edward, about fifteen miles distant, with upwards of five thousand men. Instead of this, Webb, who overrated the French forces, sent him a letter, advising him to capitulate. The letter was intercepted by Montcalm, but still forwarded to Monro. The obstinate old soldier, however, persisted in his defence, until most of his cannon were burst, and his ammunition expended. At length, in the month of August, he hung out a flag of truce, and obtained honorable terms from an enemy who knew how to appreciate his valor. Montcalm demolished the fort, carried off all the artillery and munitions of war, with vessels employed in the navigation of the lake; and having thus completed his destruction of the British defences on this frontier, returned once more in triumph with the spoils of victory, to hang up fresh trophies in the churches of Canada.
Lord Loudoun, in the mean time, formed his junction with Admiral Holbourne at Halifax, and the troops were embarked with all diligence on board of the transports. Unfortunately, the French were again too quick for them. Admiral de Bois de la Mothe had arrived at Louisburg, with a large naval and land force; it was ascertained that he had seventeen ships of the line, and three frigates, quietly moored in the harbor; that the place was well fortified and supplied with provisions and ammunition, and garrisoned with six thousand regular troops; three thousand natives, and thirteen hundred Indians.
Some hot-heads would have urged an attempt against all such array of force, but Lord Loudoun was aware of the probability of defeat, and the disgrace and ruin that it would bring upon British arms in America. He wisely, though ingloriously, returned to New York. Admiral Holbourne made a silly demonstration of his fleet off the harbor of Louisburg, approaching within two miles of the batteries, but retired on seeing the French admiral preparing to unmoor. He afterwards returned with a reinforcement of four ships of the line; cruised before Louisburg, endeavoring to draw the enemy to an engagement, which De la Mothe had the wisdom to decline; was overtaken by a hurricane, in which one of his ships was lost, eleven were dismasted, others had to throw their guns overboard, and all returned in a shattered condition to England. Thus ended the northern campaign by land and sea, a subject of great mortification to the nation, and ridicule and triumph to the enemy.
During these unfortunate operations to the north, Washington was stationed at Winchester, shorn of part of his force by the detachment to South Carolina, and left with seven hundred men to defend a frontier of more than three hundred and fifty miles in extent. The capture and demolition of Oswego by Montcalm had produced a disastrous effect. The whole country of the five nations was abandoned to the French. The frontiers of Pennsylvania, Maryland, and Virginia were harassed by repeated inroads of French and Indians, and Washington had the mortification to see the noble valley of the Shenandoah almost deserted by its inhabitants, and fast relapsing into a wilderness.
