BRILLIANT strokes came like flashes of lightning. With McClellan still setting his heart on taking Richmond, "Stonewall" Jackson was making threatening moves towards Washington. Demonstrations were begun to plant fear in the Government and cause sufficient alarm to order the withdrawal of McClellan to the defense of Washington. This daring ruse was successful inasmuch as it completely upset the plans to take Richmond, and the seat of battle was almost instantly transferred to the North. There was no denying it; Washington stood in abject fear of the brilliant Jackson. His presence in the vicinity of the National Capital caused much uneasiness. The stand against him came at Cedar Mountain, known from its hard fight as Slaughter Mountain, on the ninth of August, 1862. At a cost of about 1,400 men, the Union army frustrated Jackson and depleted his forces to the extent of 1,307. Brady's cameras were with the army at Cedar Mountain. The first photograph was taken just as one of the batteries was fording a tributary of the Rappahannock. Another picture was taken of the Union camp on the battlefield. The Confederate general, Charles S. Winder, was struck by a shell while leading his division on the field. He was taken to the house shown in one of these photographs where he died. The marks of the shells can easily be seen in the roof. It was about this time, at Harrison's Landing, that Brady met the famous Irish Brigade which was then fighting in the defense of Washington, under Brigadier-General Thomas Francis Meagher, who had taken prominent part in a recent rebellion in Ireland. A group of officers of the sturdy Irish Brigade sat before one of Brady's cameras. The charges of this brigade are among the most daring in warfare.
