Head Quarters, White Plains, 27th July, 1778.
DEAR MARQUIS,—This will be delivered to you by Major-General Greene, whose thorough knowledge of Rhode Island, of which he is a native, and the influence he will have with the people, put it in his power to be particularly useful in the expedition against that place, as well in providing necessaries for carrying it on, as in assisting to form and execute a plan of operations proper for the occasion. The honour and interest of the common cause are so deeply concerned in the success of this enterprise, that it appears to me of the greatest importance to omit no step which may conduce to it; and General Greene, on several accounts, will be able to render very essential service.
These considerations have determined me to send him on the expedition, in which, as he could not with propriety act, nor be equally useful merely in his official capacity as quartermaster-general, I have concluded to give him a command in the troops to be employed in the descent. I have, therefore, directed General Sullivan to throw all the American troops, both continental, state, and militia, into two divisions, making an equal distribution of each, to be under the immediate command of General Greene and yourself. The continental troops being divided in this manner, with the militia, will serve to give them confidence, and probably make them act better than they would alone. Though this arrangement will diminish the number of continental troops under you, yet this diminution will be more than compensated by the addition of militia; and I persuade myself your command will not be less agreeable, or less honourable, from this change in the disposition. I am, with great esteem and affection, dear marquis, your most obedient servant.
