The loss of the two small forts called Ontario and Oswego, was a considerable national misfortune. They were erected on the south side of the great lake Ontario, standing on the opposite sides of the mouth of the Onondago river, that discharges itself into the lake, and constituted a post of great importance, where vessels had been built to cruise upon the lake, which is a kind of inland sea, and interrupt the commerce as well as the motions and designs of the enemy. The garrison, as we have already observed, consisted of fourteen hundred men, chiefly militia and new-raised recruits, under the command of lieutenant-colonel Mercer, an officer of courage and experience; but the situation of the forts was very ill chosen; the materials mostly timber or logs of wood; the defences wretchedly contrived and unfinished; and, in a word, the place altogether untenable against any regular approach. Such were the forts which the enemy wisely resolved to reduce. Being under no apprehension for Crown Point, they assembled a body of troops, consisting of thirteen hundred regulars, seventeen hundred Canadians, and a considerable number of Indian auxiliaries, under the command of the marquis de Montcalm, a vigilant and enterprising officer, to whom the conduct of the siege was entrusted by the marquis de Vaudreuil, governor and lieutenant-general of New France. The first step taken by Montcalm was to block up Oswego by water with two large armed vessels, and post a strong body of Canadians on the road between Albany and the forts, to cut off all communication of succour and intelligence. In the meantime he embarked his artillery and stores upon the lake, and landed them in the bay of Nixouri, the place of general rendezvous. At another creek, within half a league of Oswego, he erected a battery for the protection of his vessels, and on the twelfth day of August, at midnight, after his dispositions had been made, he opened the trenches before fort Ontario. The garrison having fired away all their shells and ammunition, spiked up the cannon, and deserting the fort, retired next day across the river into Oswego, which was even more exposed than the other, especially when the enemy had taken possession of Ontario, from whence they immediately began to fire without intermission. Colonel Mercer being on the thirteenth killed by a cannon ball, the fort destitute of all cover, the officers divided in opinion, and the garrison in confusion, they next day demanded a capitulation, and surrendered prisoners of war, on condition that they should be exempted from plunder, conducted to Montreal, and treated with humanity. These conditions, however, the marquis did not punctually observe. The British officers and soldiers were insulted by the savage Indians, who robbed them of their clothes and baggage, massacred several men as they stood defenceless on the parade, assassinated lieutenant de la Court as he lay wounded in his tent, under the protection of a French officer, and barbarously scalped all the sick people in the hospital: finally, Montcalm, in direct violation of the articles, as well as in contempt of common humanity, delivered up above twenty men of the garrison to the Indians, in lieu of the same number they had lost during the siege; and in all probability these miserable captives were put to death by those barbarians, with the most excruciating tortures, according to the execrable custom of the country. Those who countenance the perpetration of cruelties, at which human nature shudders with horror, ought to be branded as infamous to all posterity. Such, however, were the trophies that, in the course of the American war, distinguished the operations of a people who pique themselves upon politeness, and the virtues of humanity. The prisoners taken at Oswego, after having been thus barbarously treated, were conveyed in batteaux to Montreal, where they had no reason to complain of their reception; and before the end of the year they were exchanged. The victors immediately demolished the two forts (if they deserve that denomination,) in which they found one hundred and twenty-one pieces of artillery, fourteen mortars, with a great quantity of ammunition, warlike stores, and provisions, besides two sloops, and two hundred batteaux, which likewise fell into their hands. Such an important magazine, deposited in a place altogether indefensible, and without the reach of immediate succour, was a flagrant proof of egregious folly, temerity, and misconduct.
