Two detachments, amounting each to 1,600 men, were to march from Pittsburgh and Wyoming against Detroit and Niagara. A third body of troops which was to be stationed on the Mohawk during the winter and to be powerfully reinforced in the spring, was to seize Oswego and to secure the navigation of Lake Ontario with vessels to be constructed of materials to be procured in the winter. A fourth corps was to penetrate into Canada by the St. Francis and to reduce Montreal and the posts on Lake Champlain, while a fifth should guard against troops from Quebec. Thus far America could proceed unaided by her ally. But Upper Canada being reduced another campaign would still be necessary for the reduction of Quebec. This circumstance would require that the army should pass the winter in Canada, and in the meantime the garrison of Quebec might be largely reinforced. It was therefore essential to the complete success of the enterprise that France should be induced to take a part in it. The conquest of Quebec and of Halifax was supposed to be an object of so much importance to France as well as to the United States that her aid might be confidently expected. It was proposed to request the King of France to furnish four or five thousand troops, to sail from Brest the beginning of May under convoy of four ships of the line and four frigates, the troops to be clad as if for service in the West Indies and thick clothes to be sent after them in August. A large American detachment was to act with this French army and it was supposed that Quebec and Halifax might be reduced by the beginning or middle of October. The army might then either proceed immediately against New Foundland or remain in garrison until the spring when the conquest of that place might be accomplished. It had been supposed probable that England would abandon the further prosecution of the war on the continent of North America, in which case the government would have a respectable force at its disposal, the advantageous employment of which had engaged in part the attention of Washington. He had contemplated an expedition against the British posts in Upper Canada as a measure which might be eventually eligible and which might employ the arms of the United States to advantage if their troops might safely be withdrawn from the sea-board. He had, however, considered every object of this sort as contingent. Having estimated the difficulties to be encountered in such an enterprise he had found them so considerable as to hesitate on the extent which might safely be given to the expedition admitting the United States to be evacuated by the British armies.
