HEADQUARTERS DETACHMENT CAVALRY CORPS,
July 10, 1864.

Lieutenant Colonel C. H. MORGAN,

Chief of Staff:

COLONEL: I send you by bearer a negro woman who lives in sight of the railroad near Doctor Gurley's house. She says the cars passed up once yesterday toward Petersburg and came back. Had on them soldiers as they went toward Petersburg. She was three trains go out from Petersburg this morning; the cars were empty. She says General Lee told the soldiers yesterday if they would capture for him one Yankee he would give the man who did it thirty days' furlough. A scout sent out in front of the Gurley house got within twenty or thirty yards of the enemy's pickets and saw the men in little pits, very much like our infantry skirmishers or pickets use; says that in the one on the road there were two, and a few moments after four others with bayonets fixed came walking down the road toward it. They did not see him, as he was concealed by bushes. He is of the opinion that their line is a picket-line protected by small rifle-pits.

I send this in Colonel Bryan's absence.

Very respectfully, your obedient servant,

J. E. CARPENTER,

Captain and Acting Assistant Adjutant-General.
