June 27, 1864-10.15 a. m.
Commanding Cavalry Corps:
A body of the enemy's cavalry excepting 1,000 strong was seen leaving Petersburg this morning a southerly direction on a road near the Weldon railroad, probably for the purpose of re-enforcing the enemy's cavalry that followed Wilson, of of interposing between Wilson and us on Wilson's return. To anticipate any attempt at a dash at the trains of the army Gibbeon's division has been sent to hold the crossing of the Blackwater by the old Norfolk or baxter road, and the approaches between that and the Jerusalem plan road on the right and Prince George Court-House on the left. General Ferrero's division is sent to hold from crossing of Blackwater, near Prince George Court-House to Old Court-House; the dismounted cavalry holding the crossing of Bailey's Creek, at the Old Court-House. The letter of the army covers the Jerusalem plank road as far as 4 miles from Petersburg. The commanding general desires you to join the army as soon as practicable, and be prepared for active co-operation with General Wilson to aid his return.
