SIR: I take pleasure in handing you an accurate statement of the forces on the Confederate side engaged in the battle of the 21st of July, 1861, known by some as the Battle of Bull Run and by others as that of Manassas. So far as the troops of Beauregard's immediate Army of the Potomac are concerned, my present statement is condensed from two that I prepared with the sub-returns of all the commands before me as the adjutant-general of that army, September 25th, 1861, and I can assure you of its exactness. Copies of the original papers prepared at that date will be found on page 568, Series I, Vol. II., "Official Records of the Union and Confederate Armies." In respect to the Army of the Shenandoah ( Johnston's), I have been obliged to present an estimate, my authority for which is a statement written by me in the official report of the battle, and based, as I distinctly recollect, upon official documents and returns in my hands at the time, of the accuracy of which I was and am satisfied.
Respectfully, Thomas Jordan
