Fort Ontario, counted as the best of the three forts at Oswego, stood on a high plateau at the east or right side of the river where it entered the lake. It was in the shape of a star, and was formed of trunks of trees set upright in the ground, hewn flat on two sides, and closely fitted together,—an excellent defence against musketry or swivels, but worthless against cannon. The garrison, three hundred and seventy in all, were the remnant of Pepperell's regiment, joined to raw recruits lately sent up to fill the places of the sick and dead. They had eight small cannon and a mortar, with which on the next day, Friday, the thirteenth, they kept up a brisk fire till towards night; when, after growing more rapid for a time, it ceased, and the fort showed no sign of life. Not a cannon had yet opened on them from the trenches; but it was certain that with the French artillery once in action, their wooden rampart would be shivered to splinters. Hence it was that Colonel Mercer, commandant at Oswego, thinking it better to lose the fort than to lose both fort and garrison, signalled to them from across the river to abandon their position and join him on the other side. Boats were sent to bring them off; and they passed over unmolested, after spiking their cannon and firing off their ammunition or throwing it into the well.
The fate of Oswego was now sealed. The principal work, called Old Oswego, or Fort Pepperell, stood at the mouth of the river on the west side, nearly opposite Fort Ontario, and less than five hundred yards distant from it. The trading-house, which formed the centre of the place, was built of rough stone laid in clay, and the wall which enclosed it was of the same materials; both would crumble in an instant at the touch of a twelve-pound shot. Towards the west and south they had been protected by an outer line of earthworks, mounted with cannon, and forming an entrenched camp; while the side towards Fort Ontario was left wholly exposed, in the rash confidence that this work, standing on the opposite heights, would guard against attack from that quarter. On a hill, a fourth of a mile beyond Old Oswego, stood the unfinished stockade called New Oswego, Fort George, or, by reason of its worthlessness, Fort Rascal. It had served as a cattle pen before the French appeared, but was now occupied by a hundred and fifty Jersey provincials. Old Oswego with its outwork was held by Shirley's regiment, chiefly invalids and raw recruits, to whom were now joined the garrison of Fort Ontario and a number of sailors, boatmen, and laborers.
Montcalm lost no time. As soon as darkness set in he began a battery at the brink of the height on which stood the captured fort. His whole force toiled all night, digging, setting gabions, and dragging up cannon, some of which had been taken from Braddock. Before daybreak twenty heavy pieces had been brought to the spot, and nine were already in position. The work had been so rapid that the English imagined their enemies to number six thousand at least. The battery soon opened fire. Grape and round shot swept the intrenchment and crashed through the rotten masonry. The English, says a French officer, "were exposed to their shoe-buckles." Their artillery was pointed the wrong way, in expectation of an attack, not from the east, but from the west. They now made a shelter of pork-barrels, three high and three deep, planted cannon behind them, and returned the French fire with some effect.
Early in the morning Montcalm had ordered Rigaud to cross the river with the Canadians and Indians. There was a ford three quarters of a league above the forts; [430] and here they passed over unopposed, the English not having discovered the movement. [431] The only danger was from the river. Some of the men were forced to swim, others waded to the waist, others to the neck; but they all crossed safely, and presently showed themselves at the edge of the woods, yelling and firing their guns, too far for much execution, but not too far to discourage the garrison.
The garrison were already disheartened. Colonel Mercer, the soul of the defence, had just been cut in two by a cannon-shot while directing the gunners. Up to this time the defenders had behaved with spirit; but despair now seized them, increased by the screams and entreaties of the women, of whom there were more than a hundred in the place. There was a council of officers, and then the white flag was raised. Bougainville went to propose terms of capitulation. "The cries, threats, and hideous howling of our Canadians and Indians," says Vaudreuil, "made them quickly decide." "This," observes the Reverend Father Claude Godefroy Cocquard, "reminds me of the fall of Jericho before the shouts of the Israelites." The English surrendered prisoners of war, to the number, according to the Governor, of sixteen hundred, [432] which included the sailors, laborers, and women. The Canadians and Indians broke through all restraint, and fell to plundering. There was an opening of rum-barrels and a scene of drunkenness, in which some of the prisoners had their share; while others tried to escape in the confusion, and were tomahawked by the excited savages. Many more would have been butchered, but for the efforts of Montcalm, who by unstinted promises succeeded in appeasing his ferocious allies, whom he dared not offend. "It will cost the King," he says, "eight or ten thousand livres in presents." [433]
[432] Vaudreuil au Ministre, 20 Août, 1756. He elsewhere makes the number somewhat greater. That the garrison, exclusive of civilians, did not exceed at the utmost fourteen hundred, is shown by Shirley to Loudon, 5 Sept. 1756. Loudon had charged Shirley with leaving Oswego weakly garrisoned; and Shirley replies by alleging that the troops there were in the number as above. It was of course his interest to make them appear as numerous as possible. In the printed Conduct of Major-General Shirley briefly stated, they are put at only ten hundred and fifty.
[433] Several English writers say, however, that fifteen or twenty young men were given up to the Indians to be adopted in place of warriors lately killed.
The loss on both sides is variously given. By the most trustworthy accounts, that of the English did not reach fifty killed, and that of the French was still less. In the forts and vessels were found above a hundred pieces of artillery, most of them swivels and other light guns, with a large quantity of powder, shot, and shell. The victors burned the forts and the vessels on the stocks, destroyed such provisions and stores as they could not carry away, and made the place a desert. The priest Piquet, who had joined the expedition, planted amid the ruin a tall cross, graven with the words, In hoc signo vincunt; and near it was set a pole bearing the arms of France, with the inscription, Manibus date lilia plenis. Then the army decamped, loaded with prisoners and spoil, descended to Montreal, hung the captured flags in the churches, and sang Te Deum in honor of their triumph.
