 HEADQUARTERS ARMIES OF THE UNITED STATES,

                                          CITY POINT VIRGINIA, September 12, 1864.
 
Major-General W. T. Sherman, commanding Military Division of the Mississippi
 
General: I send Lieutenant-Colonel Horace Porter of my staff, with this. Colonel Porter will explain to the exact condition of affairs here, better than I can do in the limits of a letter. Although I feel myself strong enough now for offensive operations, I am holding on quietly, to get advantage of recruits and convalescents, who are coming forward very rapidly. My lines are necessarily very long, extending from Deep Bottom, north of the James, across the peninsula formed by the Appomattox and the James, and south of the Appomattox to the Weldon road. This line is very strongly fortified, and can be held with comparatively few men; but, from its great length, necessarily takes many in the aggregate. I propose, when I do move, to extend my left so as to control what is known as the Southside, or Lynchburg & Petersburg road; then, if possible, to keep the Danville road cut. At the same time this move is made, I want to send a force of from six to ten thousand men against Wilmington. The way I propose to do this is to land the men north of Fort Fisher, and hold that point. At the same time a large naval fleet will be assembled there, and the iron-cads will run the batteries as they did at Mobile. This will give us the same control of the harbor of Wilmington that we now have of the harbor of Mobile. What you are to do with the forces at your command, I do not exactly see. The difficulties of supplying your army, except when they are constantly moving beyond where you are, I plainly see. If it had not been for Price's movement, Canby could have sent twelve thousand more men to Mobile. From your command on the Mississippi, an equal number could have been taken. With these forces, my idea would have been to divide them, sending one-halt to Mobile, and the other half to Savannah. You could then move as proposed in your telegram, so as to threaten Macon and Augusta equally. Whichever one should be abandoned by the enemy, you could take and open up a new base of supplies. My object now in sending a staff-officer to you is not so much to suggest operations for you as to get your views, and to have plans matured by the time every thing can got ready. It would probably be the 5th of October before any of tie plans here indicated will be executed. If you have any promotions to recommend, send the names forward, and I will approve them.

In conclusion, it is hardly necessary for me to say that I feel you have accomplished the most gigantic undertaking given to any general in this war, and with a skill and ability that will be acknowledged in history' as unsurpassed, if not unequaled. It gives me as much pleasure to record this in your favor as it would in favor of any living man, myself included.
            Truly yours,
                      U. S. Grant, Lieutenant-General.
