The conduct of Count de Guichen, on the 17th of April, and the 15th and 19th of May, in the West Indies, does great honor to the national bravery, as well as to their science in naval tactics, and shows that there is no cause to fear that the enemy will obtain any advantage there. Yet nothing has yet been done on either side that seems decisive. The advantages, which Spain has gained in West Florida, and particularly of late at Mobile, and the probability that she will succeed in gaining both the Floridas, show that the English are on the losing hand in that quarter; but it is not the loss of both the Floridas, nor of all the West India Islands, in my opinion, that will induce them to make peace, and acknowledge the independence of America in alliance with France. They will see every possession they have beyond the island lopped off, one after another, before they will do this. I pretend not to know, to what part of America M. de Ternay and M. de Rochambeau are destined, but to whatever part it is, whether Canada, Nova Scotia, New York, Carolina, or Georgia, I have no hopes of anything decisive from their operations, although they should be instructed to co-operate with General Washington. If they should be destined against Canada or Nova Scotia, they may succeed; but this success will not be decisive. If they are intended against New York, I have no hopes of their success. The naval force is not sufficient to command the seas. Admiral Graves, added to the ships before at New York, will be superior; and I shall venture to give my opinion, that without a superiority of naval force, clear and indisputable, New York will never be taken. It is so situated, so fortified, it is garrisoned with troops so accustomed to war, and so embittered and inflamed by cruel passions, carefully nursed up in their breasts by their King and their Generals, and it is universally regarded by them a port of such essential importance, that I confess I should despair of success against it, with an army twice as numerous as that of the Generals Washington and Rochambeau united, while the English are masters of the seas, or even while they have there an equality of naval power. Most people in Europe have wondered at the inactivity of the American army, for these two years past; but it is merely from want of knowledge and attention. The true cause of it is, the English have confined themselves to their strong holds in seaport towns, and have been sheltered from all attacks and insults by the guns of their men-of-war, and forever will be so, while they have the superiority at sea. If our army had been three times as numerous as it was, it must have remained inactive, without a fleet to co-operate with it; for an attack upon New York without a fleet, would have been only sacrificing the lives of thousands of brave men, without a possibility of succeeding.
