_Battle of Fair Oaks_ (May 31, June l).--While these stirring events had been going on in the Shenandoah Valley, McClellan had pushed his left wing across the Chickahominy. A terrible storm had flooded the swamps, turned the roads to mud, and converted the Chickahominy Creek into a broad river. Johnston seized the opportunity to fall with tremendous force upon the exposed wing. At first, the Confederates swept all before them, but General Sumner throwing his men across the tottering bridges over the Chickahominy, checked the column which was trying to seize the bridges and thus separate the two portions of the army. General Johnston was severely wounded. Night put an end to the contest. In the morning, the Confederates renewed the attack, but the loss of their general was fatal, and they were repulsed in great disorder. _The Union Army Checked_.--General Lee, who now took command of the Confederate army, was anxious to assume the offensive. [Footnote: Robert Edward Lee was born in Stratford, Virginia, Jan. 19, 1807; died in Lexington, Oct. 12, 1870. His father, Henry Lee, was the celebrated "Light-horse Harry" of Revolutionary fame. Robert early evinced a love for a military life, and during his West Point course became noted for his devotion to his studies. In the Mexican war he was Scott's chief engineer, and was thrice brevetted for his services. When Virginia seceded, he threw in his fortunes with his native State, although Scott had already intimated his intention of nominating him as his successor. Lee was immediately appointed major-general of the Virginia forces, and was soon after designated to fortify Richmond. The wonderful success he achieved in the Seven-Days fight made "Uncle Robert," as he was familiarly called, the most trusted of the Confederate leaders. For three years he baffled every attempt to take Richmond, which fell only with the government of which it was the capital, and the army and general which were its defence. General Lee was handsome in face and figure, a graceful rider, grave and silent in deportment--just the bearing to captivate a soldier; while his deep piety, truth, sincerity, and honesty won the hearts of all.] General Stuart led off (June 12) with a bold cavalry raid, in which he seized and burned supplies along the railroad leading to White House, made the entire circuit of the Union army, and returned to Richmond in safety. McClellan also meditated an advance, and Hooker had pushed his pickets within sight of the Richmond steeples. At this moment, there came news of the "same apparition which had frightened Banks" in the Shenandoah. Stonewall Jackson had appeared near Hanover Court House, and threatened the Union communications with White House. There was no longer any thought of moving on Richmond. Hooker was recalled. McClellan resolved to "change his base" of supply from the York River to the James. [Illustration: GENERAL ROBERT E. LEE.]
