Washington was greatly embarrassed by his uncertainty with respect to the force which he might count upon to cooperate with the expected succors from France. Writing to Congress on this subject he said: "The season is come when we have every reason to expect the arrival of the fleet, and yet, for want of this point of primary consequence, it is impossible for me to form a system of cooperation. I have no basis to act upon, and, of course, were this generous succor of our ally now to arrive, I should find myself in the most awkward, embarrassing, and painful situation. The general and the admiral, from the relation in which I stand, as soon as they approach our coast, will require of me a plan of the measures to be pursued, and there ought of right to be one prepared; but, circumstanced as I am, I cannot even give them conjectures. From these considerations I have suggested to the committee, by a letter I had the honor of addressing them yesterday, the indispensable necessity of their writing again to the States, urging them to give immediate and precise information of the measures they have taken and of the result. The interest of the States, the honor and reputation of our councils, the justice and gratitude due to our allies, all require that I should, without delay, be enabled to ascertain and inform them what we can or cannot undertake. There is a point which ought now to be determined, on the success of which all our future operations may depend, on which, for want of knowing our prospects, I can make no decision. For fear of involving the fleet and army of our allies in circumstances which would expose them, if not seconded by us, to material inconvenience and hazard, I shall be compelled to suspend it, and the delay may be fatal to our hopes."
While this uncertainty still continued, the expected succors from France, consisting of a fleet of eight ships of the line, with frigates and other vessels, under the Chevalier de Ternay, having about 6,000 troops on board under General the Count de Rochambeau, reached Rhode Island on the evening of the 10th of July (1780), and in a few days afterward Lafayette arrived at Newport from Washington's headquarters to confer with his countrymen.
At the time of the arrival of the French in Rhode Island, Admiral Arbuthnot had only four sail of the line at New York, but in a few days Admiral Graves arrived from England with six sail of the line, which gave the British a decided superiority over the French squadron, and therefore Sir Henry Clinton, without delay, prepared for active operations. He embarked about 8,000 men and sailed with the fleet to Huntington bay, in Long Island, with the intention of proceeding against the French at Newport. The militia of Massachusetts and Connecticut were ordered by Washington to join the French forces in Rhode Island, and the combined army there thought itself able to give the British a good reception.
As the garrison of New York was weakened by the sailing of the armament under Clinton, Washington, having received considerable reinforcements, suddenly crossed the North river and advanced toward New York; that movement brought Clinton back to defend the place and consequently Washington proceeded no further in his meditated enterprise.
The want of money and of all necessaries still continued in the American camp, and the discontent of the troops, gradually increasing, was matured into a dangerous spirit of insubordination. The men, indeed, bore incredible hardships and privations with unexampled fortitude and patience, but the army was in a state of constant fluctuation; it was composed, in a great measure, of militia harassed by perpetual service and obliged to neglect the cultivation of their farms and their private interests in order to obey the calls of public duty, and of soldiers on short enlistments, who never acquired the military spirit and habits.
In consequence of an appointment, Washington and suite set out to a conference with Count Rochambeau and Admiral de Ternay, and on the 21st of September (1780) met them at Hartford, in Connecticut, where they spent a few days together, and conversed about a plan for the next campaign.
The conference was useful in making the respective commanders well acquainted with each other, and promoting a spirit of harmony between them; but it led to no settled plan for the next campaign. A plan of operations for the combined forces, which had been drawn up by Washington and sent to Rochambeau by Lafayette when he went to Newport, had contemplated the superiority of the naval force of the French, which had now ceased to exist in consequence of the arrival of Admiral Graves with a fleet of six ships of the line. It was consequently agreed that nothing could be done in the way of offensive movements until the arrival of a second division of the French fleet and army from Brest, which was expected, or that of the Count de Guichen from the West Indies. In the sequel, neither of these arrivals took place. The second French division was blockaded at Brest, and never came to this country, and de Guichen sailed direct to France from the West Indies. Meantime Admiral Arbuthnot blockaded the French fleet at Newport, and Rochambeau's army remained there for its protection. Both the parties remained watching each other's movements, and depending on the operations of the British and French fleets. Washington crossed the Hudson to Tappan and remained there till winter.
Washington did not relinquish without infinite chagrin the sanguine expectations he had formed of rendering this campaign decisive of the war. Never before had he indulged so strongly the hope of happily terminating the contest. In a letter to an intimate friend, this chagrin was thus expressed: "We are now drawing to a close an inactive campaign, the beginning of which appeared pregnant with events of a very favorable complexion. I hoped, but I hoped in vain, that a prospect was opening which would enable me to fix a period to my military pursuits and restore me to domestic life. The favorable disposition of Spain, the promised succor from France, the combined force in the West Indies, the declaration of Russia (acceded to by other powers of Europe, humiliating the naval pride and power of Great Britain), the superiority of France and Spain by sea in Europe, the Irish claims and English disturbances, formed in the aggregate an opinion in my breast (which is not very susceptible of peaceful dreams), that the hour of deliverance was not far distant; for that, however unwilling Great Britain might be to yield the point, it would not be in her power to continue the contest. But, alas, these prospects, flattering as they were, have proved delusive, and I see nothing before us but accumulating distress. We have been half of our time without provisions and are likely to continue so. We have no magazines nor money to form them. We have lived upon expedients until we can live no longer. In a word, the history of the war is a history of false hopes and temporary devices, instead of system and economy. It is in vain, however, to look back, nor is it our business to do so. Our case is not desperate if virtue exists in the people, and there is wisdom among our rulers. But to suppose that this great revolution can be accomplished by a temporary army, that this army will be subsisted by State supplies and that taxation alone is adequate to our wants is in my opinion absurd, and as unreasonable as to expect an inversion of the order of nature to accommodate itself to our views. If it were necessary it could be easily proved to any person of a moderate understanding that an annual army or any army raised on the spur of the occasion besides being unqualified for the end designed is, in various ways that could be enumerated, ten times more expensive than a permanent body of men under good organization and military discipline, which never was nor will be the case with raw troops. A thousand arguments, resulting from experience and the nature of things, might also be adduced to prove that the army, if it is to depend upon State supplies, must disband or starve, and that taxation alone (especially at this late hour) cannot furnish the means to carry on the war. Is it not time to retract from error and benefit by experience? Or do we want further proof of the ruinous system we have pertinaciously adhered to?"
While the respective armies were in the state of inaction to which we have just referred, the whole country was astounded by the discovery of Arnold's treason. The details of this sad affair disclosed traits in the character of this officer which were previously unknown, and, by the public generally, unsuspected.
The great service and military talents of General Arnold, his courage in battle and patient fortitude under excessive hardships had secured to him a high place in the opinion of the army and of his country. Not having sufficiently recovered from the wounds received before Quebec and at Saratoga to be fit for active service, and having large accounts to settle with the government, which required leisure, he was, on the evacuation of Philadelphia in 1778, appointed to the command in that place.
