Mr. S. A. Copper
At 8:30 a. m., his message states that from reports received by him, the impression is that the enemy is going to cross the Potomac at Walker's Landing.
At 12: 45 p. m., he reports from Falls Church that the enemy's advanced pickets, on the Leesburg and Georgetown turnpike are three-fourths of a mile this side of Difficult Creek, and that a regiment of Mississippi cavalry, the Jeff Davis Legion, is at the bridge over the creek.
At 1:30 p. m., from Falls Church his dispatch to the chief of staff states that the squadron on the Vienna road reports the enemy to be approaching from that direction in some force; that one of his men had been badly wounded in a skirmish. Gives it as his opinion that the enemy is only making a show of force to conceal his movements on the upper Potomac.
Sept. 4, 1862: Major General F. J. Porter from Headquarters Fifth Army Corps at Hall's Hill, sends a message at 4:30 p. m., to Major Gen'l McClellan stating that Gen'l Morell from Minor's Hill reports that the enemy has begun an attack on the Union pickets, with artillery, infantry and cavalry.
