Johnston's army being his objective point, and the heart of Georgia his ultimate aim.

If successful he will secure the line from Chattanooga to Mobile with the aid of Banks.
Sigel cannot spare troops from his army to reinforce either of the great armies, but he can aid them by moving directly to his front.

This he has been directed to do, and is now making preparations for it.

Two columns of his command will make south at the same time with the general move; one from Beverly, from ten to twelve thousand strong, under Major-General Ord; the other from Charleston, Va., principally cavalry, under Brig.-General Crook.

The former of these will endeavor to reach the Tennessee and Virginia Railroad, about south of Covington, and if found practicable will work eastward to Lynchburg and return to its base by way of the Shenandoah Valley, or join you.
