No. 32. Report of Colonel Andrew Porter, Sixteenth U. S. Infantry, commanding Second Division and First Brigade, Second Division.
HDQRS. FIRST BRIGADE, SECOND DIVISION, Arlington, Va., July 25, 1861.
SIR: I have the honor to submit the following account of the operations of the First Brigade, Second Division, of the Army, in the battle before Manassas, on the 21st instant.* The brigade was silently paraded in light marching order at 2 o'clock in the morning of that day, composed as follows, viz: Griffin's battery; marines, Major Reynolds; Twenty-seventh New York Volunteers, Colonel Slocum; Fourteenth New York State Militia, Colonel Wood; Eighth New York State Militia, Colonel Lyons; battalion regulars, Major Sykes; one company Second Dragoons, two companies First Cavalry, four companies First Cavalry, four companies Second Cavalry, Major Palmer.

The column moved forward, however, before they were completed, and in about thirty minutes emerged from the timber, when the rattle of musketry and occasional crash of round shot through the leaves and branches of the trees in our vicinity betokened the opening of battle.
The head of the brigade was immediately turned slightly to the right, in order to gain time and room for deployment on the right of the Second Brigade. Griffin's battery found its way through the timber to the fields beyond, followed promptly by the marines, while the Twenty-
