Major-General William T. Sherman to Major-General Ulysses S. Grant, July 12, 1863—12 m.

HEADQUARTERS,        

Before Jackson, Miss., July 12, 1863--12 m.

Port Hudson being ours, and Holmes repulsed at Helena, the Missouri forces should be pushed to Little Rock at once. Mobile should be attacked also, from the direction of New Orleans, and, when it is taken, we could move on Selma. I fear the weather is too hot for me to march to Grenada. Would it not be better to move on Grenada from Memphis, and on Columbus, Miss., from Corinth, leaving me to fight Johnston according to circumstances, and to destroy the Central road as far as Canton and Big Black River?

Harrisonburg, La., should be attacked by a brigade. It would paralyze the Washita country. Can't Grierson join me by land?

All is well with me now. I have ten days' supplies. Will send my supply train to Black River, under good escort, as soon as unloaded.

W. T. SHERMAN,        

Major-General.

General GRANT,

        Vicksburg.
