In a long and serious letter to congress, he apologized for not obeying their orders to deliver the plan with his observations upon it to the Marquis; and, entering into a full investigation of all its parts, demonstrated the mischiefs, and the dangers, with which it was replete.  This letter was referred to a committee, whose report admits the force of the reasons urged by the Commander-in-chief against the expedition, and their own conviction that nothing important could be attempted unless the British armies should be withdrawn from the United States; and that, even in that event, the present plan was far too complex.

Men, however, recede slowly and reluctantly from favourite and flattering projects on which they have long meditated; and the committee, in their report, proceeded to state the opinion that the posts held by the British in the United States would probably be evacuated before the active part of the ensuing campaign; and that, therefore, eventual measures for the expedition ought to be taken.

This report concludes with recommending “that the general should be directed to write to the Marquis de Lafayette on that subject; and also to write to the minister of these states at the court of Versailles very fully, to the end that eventual measures may be taken, in case an armament should be sent from France to Quebec, for co-operating therewith, to the utmost degree, which the finances and resources of these states will admit.”

This report also was approved by congress, and transmitted to the Commander-in-chief; who felt himself greatly embarrassed by it.  While his objections to the project retained all their force, he found himself required to open a correspondence for the purposes of soliciting the concurrence of France in an expedition he disapproved, and of promising a co-operation he believed to be impracticable.  In reply to this communication, he said, “The earnest desire I have strictly to comply in every instance, with the views and instructions of congress, can not but make me feel the greatest uneasiness, when I find myself in circumstances of hesitation or doubt, with respect to their directions.  But the perfect confidence I have in the justice and candour of that honourable body, emboldens me to communicate, without reserve, the difficulties which occur in the execution of their present order; and the indulgence I have experienced on every former occasion, induces me to imagine that the liberty I now take will not meet with disapprobation.”

After reviewing the report of the committee, and stating his objections to the plan, and the difficulties he felt in performing the duty assigned to him, he added, “But if congress still think it necessary for me to proceed in the business, I must request their more definitive and explicit instructions, and that they will permit me, previous to transmitting the intended despatches, to submit them to their determination.

“I could wish to lay before congress more minutely the state of the army, the condition of our supplies, and the requisites necessary for carrying into execution an undertaking that may involve the most serious events.  If congress think this can be done more satisfactorily in a personal conference, I hope to have the army in such a situation before I can receive their answer, as to afford me an opportunity of giving my attendance.”
