White Plains, 10th August, 1778.
My Dear Marquis,—Your favour of the 6th instant, which came to my hands yesterday, afforded a fresh proof of the noble principles on which you act, and has a just claim to my sincere and hearty thanks. The common cause, of which you have been a zealous supporter, would, I knew, be benefitted by General Greene's presence at Rhode Island, as he is a native of that state, has an interest with the people, and a thorough knowledge of the country, and, therefore, I accepted his proffered services; but I was a little uneasy, lest you should conceive that it was intended to lessen your command. General Greene did not incline to act in a detached part of the army, merely as quartermaster-general; nor was it to be expected. It became necessary, therefore, to give him a detached command, and consequently to divide the continental troops. Your cheerful acquiescence in the measure, after being appointed to the command of the brigades which marched from this army, obviated every difficulty, and gave me singular pleasure.
I am very happy to find that the standards of France and America are likely to be united under your command, at Rhode Island. I am persuaded, that the supporters of each will be emulous to acquire honour, and promote your glory upon this occasion. The courier to Count d'Estaing is waiting. I have only time, therefore, to assure you, that, with most perfect esteem, and exalted regard, I have the honour to be, my dear marquis, your obedient and affectionate servant.
