Whatever the outcome of the Seven Days' Battle another year was to demonstrate beyond question that the wounding of General Johnston at Fair Oaks had left the Confederate army with an even abler commander. On such a field as Chancellorsville was to be shown the brilliancy of Lee as leader, and his skilful maneuvers leading to the invasion of the North. And the succeeding volume will tell, on the other hand, how strong and compact a fighting force had been forged from the raw militia and volunteers of the North.

Lincoln had reluctantly consented to the plan, fearing sufficient protection was not provided for Washington. By the battle of Kernstown, March 23d, in the Valley of Virginia, Jackson, though defeated, so alarmed the Administration that McDowell was ordered to remain at Manassas to protect the capital. The reverse at Kernstown was therefore a real triumph for Jackson, but with his small force he had to keep up the game of holding McDowell, Banks, and Frémont from reënforcing McClellan. If he failed, 80,000 troops might move up to Richmond from the west while McClellan was approaching from the North. But Jackson, on May 23d and 25th, surprised Banks' forces at Front Royal and Winchester, forcing a retreat to the Potomac. At the news of this event McDowell was ordered not to join McClellan in front of Richmond.

They were so in arms, at West Point, in Mexico and throughout the war. General Joseph E. Johnston (on the left), who had led the Confederate forces since Bull Run, was wounded at Fair Oaks. That wound gave Robert E. Lee (on the right) his opportunity to act as leader. After Fair Oaks, Johnston retired from the command of the army defending Richmond. The new commander immediately grasped the possibilities of the situation which confronted him. The promptness and completeness with which he blighted McClellan's high hopes of reaching Richmond showed at one stroke that the Confederacy had found its great general. It was only through much sifting that the North at last picked military leaders that could rival him in the field.
