Porter, Major General Commanding, Headquarters Army Corps, Hall's Hill, in his report to General Marcy states that a battery supported by cavalry suddenly appeared on Barnett's Hill and opened fire upon Pleasanton at Falls Church, while dismounted cavalry fired upon and killed 3 of his mounted pickets, who, armed only with sabers and pistols, could not contend with the enemy protected by timber. Pleasanton replied with his battery but the shots fell very short. The enemy supposed to have come from direction of Hunter's Mill returned toward Vienna. He states that the country beyond his picket lines affords every facility for such attacks, and that the commanding general must expect them to be frequent so long as the enemy continues in large force in his front and wishes to divert attention from other movements, that from the opposite hills his camp and movements are open to view of the enemy. [Illustration: Mr. R. J. Yates] Sept. 4, 1862: Brig. Gen'l A. Pleasanton from his camp near Fort Albany, Va., in his report to Brig. Gen. R. B. Marcy, chief of staff, written at 5 a. m., states that he is about to be off with the sixth cavalry and two other companies for Falls Church where he expects to make his headquarters and from whence he will scout as directed. He suggests that the telegraph be extended to Falls Church and asks that supplies for his command be forwarded by railroad to a point opposite Falls Church. [Illustration: 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.
