Head Quarters Armies of the United States,
City Point Va. July 15th 1864
Maj. Gen. H. W. Halleck
Chief of Staff of the Army
General.
In view of the possible recurrence of the late raid into Maryland I would suggest the following precautions be taken.
First, there should be an immediate call for all the troops we are likely to require.
Second, Washington City, Baltimore and Harper's Ferry should be designated as schools of instruction, and all troops raised east of the state of Ohio should be sent to one of those three places as fast as raised. Nashville, Decatur & Stevenson should also be named as schools of instruction and all troops raised in Ohio and west of it, should be sent to those.
By doing this we always have the / benefit of our increased force and they in turn improve more rapidly by contact with veteran troops. To supply Sherman, all the rolling stock that can possibly be got to him should be sent. An effort ought to be made to transfer a large portion of the stores now at Nashville to Chattanooga. This might be facilitated by withdrawing for a while the rolling stock from the Nashville & Reynoldsburg road, and a large part of the stock from the Ky. roads.
There is every indication now, judging from the tone of the Southern forces, that unless Johnson is reinforced Atlanta will not be defended. They seem to calculate largely upon driving Sherman out by keeping his lines of communication cut. If he can supply himself once with Ordnance and Quartermaster's stores, and partially with subsistence, he will find no difficulty in staying until a permanent / line can be opened with the south coast. The road from Chattanooga to Atlanta will be much more easily defended than that north of the Tennessee. With the supplies above indicated at Chattanooga, with say sixty days provisions there, I think there will be no doubt but the country will supply the balance. Sherman will, once in Atlanta, devote himself to collecting the resources of the country. He will take every thing the people have and will then issue from the stores so collected to rich and poor alike. As he will take all their stock, they will have no use for grain further than is necessary for bread.
If the enemy do not detach from here against Sherman they will, in case Atlanta falls, bring most of Johnson's Army here with the expectation of driving us out, and then unite against Sherman. again They will fail if they attempt this programme. My greatest fear is, of their sending troops / to Johnston first.
Sherman ought to be notified of the possibility of a Corps going from here and should be prepared to take up a good defensive position in case one is sent, one which he can hold against such increase.
If Hunter cannot get to Gordonsville & Charlottesville to cut the rail-roads he should make all the valleys south of the B. & O. road a desert as high up as possible. I do not mean that houses should be burned but every particle of provisions and stock should be removed and the people notified to move out. I am Gen. very respectfully
Your obt. svt.
