besides one hundred and seventy-five stand of arms, a large quantity of accouterments and blankets, and quite one hundred and fifty hast.

The effect of this day's conflict was to satisfy the enemy he could not force a passage across Bull Run in the face of our troops, and led him into the flank movement of the 21st of July and the battle of Manassas, the details of which will be related in another paper.

Herewith I have the honor to transmit the reports of the several brigade commanders engaged and of the artillery; also a map of the field of battle.*

The rendition of this report, it is proper to say in conclusion, has been unavoidably delayed by the constantly engrossing administrative duties of the commander of an army corps composed wholly of volunteers, duties vitally essential to its well being and future efficiency, and which I could not set aside or postpone on any account.

I have the honor to be, general, your obedient servant,

G. T. BEAUREGARD,

General, Commanding.

General S. COOPER,

Adjutant and Inspector-General, C. S. Army.
