HEADQUARTERS SIXTH ARMY CORPS,
Six miles from Danville, April 27, 1865-9.40 a. m.

Major-General SHERIDAN,

Commanding, &c.:

GENERAL: Your dispatch of 8 p. m. yesterday, with its inclosure, is just received, and the pontoon train will be sent immediately to report to you at Abbyville, though as it is so far in advance of that point I fear it may not reach you in time to be of service. Should you not need it, please notify the officer in charge in order that he may return to the railroad crossing of the Staunton river. I am now with the main column about six miles from Danville, but my advance of one brigade is no doubt in possession of the place at this time. The telegraph line is in working order, and if you have operators with you, you can communicate at any time with me by the wires. Accompanying this are copies of dispatches that I have been directed to furnish you.

Very respectfully, your obedient servant,

H. G. WRIGHT,

Major-General, Commanding.
