The diversion of the enemy's cavalry from the south side of the Chickahominy was its main purpose, for in the presence of such a force as Lee's contracted lines would now permit him to concentrate behind the Chickahominy, the difficulties of crossing that stream would be largely increased if he also had at hand a strong body of horse, to gain the time necessary for him to oppose the movement at the different crossings with masses of his infantry.
The order calling for two divisions for the expedition, I decided to take Gregg's and Torbert's, leaving Wilson's behind to continue with the infantry in its march to the James and to receive instructions directly from, the headquarters of the army.

"General Sheridan leaves here to-morrow morning with instructions to proceed to Charlottesville, Va., and to commence there the destruction of the Virginia Central railroad, destroying this way as much as possible.

The complete destruction of this road and of the canal on James River is of great importance to us.

According to the instructions I sent to General Halleck for your guidance, you will proceed to Lynchburg and commence there.

It would be of great value to us to get possession of Lynchburg for a single day.
