CULPEPER COURT-HOUSE, March 24, 1864.

There are many artillery units stationed in Washington to defend that city. The defenses of Washington are formidable though, and certainly not all of those units are necessary to repel any attack. They would be of more service with the Army of the Potomac. I wrote Gen. Halleck,
Chief of Staff:
Will you please send me a map, with lines marked, showing the territory now occupied by our forces; also a copy of the returns of the army you showed me? If practicable to spare them from their present stations, three regiments of heavy artillery, one commanded by Colonel Tidball to be one of them, could be advantageously used with the Army of the Potomac.
