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.
In this state of mind, he received the magnificent plan already prepared by congress.

He was forcibly struck with the impracticability of executing that part of it which was to be undertaken by the United States, should the British armies continue in their country; and with the serious mischief which would result to the common cause, as well from diverting so considerable a part of the French force from other objects to one which was, in his opinion, so unpromising, as from the ill impression which would be made on the court and nation by the total failure of the American government to execute its part of a plan originating with itself; a failure which would, most probably, sacrifice the troops and ships employed by France.
On comparing the naval force of England with that of France in the different parts of the world, the former appeared to him to maintain a decided superiority, and consequently to possess the power of shutting up the ships of the latter which might be trusted into the St.
Lawrence.

To suppose that the British government would not avail itself of this superiority on such an occasion, would be to impute to it a blind infatuation, or ignorance of the plans of its adversary, which could not be safely assumed in calculations of such serious import.
[Sidenote: General Washington urges reasons against the plan.] A plan too, consisting of so many parts, to be prosecuted both from Europe and America, by land and by water; which, to be successful, required such a harmonious co-operation of the whole, such a perfect coincidence of events, appeared to him to be exposed to too many accidents, to risk upon it interests of such high value.
[Illustration: George Washington _From the portrait by John Trumbull_ _Colonel Trumbull, whose portraits of Washington, Hamilton, Jay, Adams, George Clinton and other Revolutionary contemporaries form a notable gallery, was General Washington's aide-de-camp at the outbreak of the War for Independence, and during its progress became a pupil of Benjamin West, in London.

The news of Andre's execution fastened upon him the suspicion of being a spy, and he spent eight months in an English prison.

Returning to America he painted this and other portraits of Washington, as well as a number of historical pictures, including the "Resignation of Washington at Annapolis," which hangs in the Capitol at Washington._] 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.
