June 19, 1864 - 10 p. m.
[General A. A. HUMPHREYS:]
GENERAL: A colored man named Riley had been sent in from the Second Division, Eighteenth Army Corps. He is very ignorant and makes a very confused statement; ;but the following connected store is elicited from him: He says that up to Friday a week ago he was living in Richmond; that at that time he hired himself as a servant to a Lieutenant Phillips, of the First South Carolina Rifles; that he went with him to where Grant was on the Chickahominy; that on the Monday following went with a wagon train which he understood to belong to Wilcox's division to some place near Malvern Hill; that he understood his master to be in McGowan's brigade; that day before yesterday,at about 6 p. m., "right smart" of troops having moved before, he went, as he was ordered to do, with a wagon train of, say, 100 wagons, which he thinks was the train of Wilcox's division, to a pontoon bridge, which they reached yesterday at 12 o'clock; that after crossing it they came down toward Petersburg, crossing the railroad where it was torn up; that the wagon train encamped last night, and that this morning he came on, leaving Petersburg to the right, till he struck the Appomattox River; that he was fired upon by the rebel and Union pickets and that he swam the river to our lines.
His story has borne the test of a very careful examination, and the First South Carolina Regiment, in McGowan's brigade, was originally a battalion and was known as the First South Carolina Rifles. Our scouts to-day went out on the left to the Jerusalem plank road, the first large road west of the Norfolk and Petersburg Railroad. They followed it southerly to a point where they found a post which was marked as being four miles from Petersburg; they went half a mile beyond, where they found a road going westerly from it. At the intersection was a rebel cavalry picket of about twenty-five men, who fired upon the scouts and they returned. On their was they saw the rebels very busily engaged in the erection of a considerable earth-work, or fort, as they call it, about a mile and a half south of Petersburg and about half a mile westerly of the Jerusalem plank road before alluded to. Between this earth-work and the Jerusalem plank road the rebels had a skirmish line.
