AUGUST 9, 1862. - Battle of Cedar Run or Cedar (or Slaughter) Mountain, Va.

Report of Brigadier General George H. Gordon, U. S. Army, commanding Third Brigade, First Division, Second Corps, Army of Virginia.

HEADQUARTERS THIRD BRIGADE,
Camp near Culpeper, August 11, 1862.

SIR: I have the honor to make the following report of the part taken by my brigade in the recent battle of Saturday, August 9, at Cedar Mountain, with the enemy under General (Stonewall) Jackson:

At 9 a. m. on the morning of the 9th, after a hurried march of the day before, which was prolonged until 12 o'clock at night, I received orders to remove my brigade from the town of Culpeper, where we were in bivouac, rapidly to the front, as General Crawford, commanding First Brigade, First Division, had been attacked and required assistance.

At this hour I heard quite a rapid musketry firing in my front, behind a range of timber distant about one-third of a mile from my position. I received an order to move at once with my brigade and support General Crawford, who was engaging the enemy's left. I moved rapidly from my well-chosen and exceedingly strong position, gaining the scene of action as briefly as a double-quick movement could carry me. I led into action the Second Massachusetts Regiment, Colonel G. L. Andrews; the Third Wisconsin, Colonel Ruger; and the Twenty-seventh Indiana, Colonel Colgrove. I should state that five companies of the Third Wisconsin Regiment, previously deployed as skirmishers in this same timber, had been ordered by General Williams to join Gen-
