Following the line of the Pamunkey, McClellan's advance-guard reached the Chickahominy on the 21st of May, and could plainly see the spires and steeples of Richmond, which was thrown into a state of great alarm. Rain fell most of the time, and the rise of the Chickahominy carried away the bridges, made the surrounding country a swamp, and badly divided the Union army.

MOIST WEATHER AT THE FRONT.

One of the most effective means employed by the Confederate commander against the Union advance was by creating a diversion in the Shenandoah Valley and fear for the safety of Washington. Rather than lose that, our government would have sacrificed the Army of the Potomac. General Johnston had sent Stonewall Jackson into the Valley, where Banks was in command. He was another of the political generals, wholly unfitted for the responsibilities placed in his hands.

At the opening of hostilities, Banks was so confident that he telegraphed the government that Jackson was on the eve of being crushed; but it proved the other way. Banks was completely outgeneraled and sent flying toward Washington. His troops marched more than thirty miles a day, and would have been captured or destroyed to a man had Jackson continued his pursuit, but his forces were fewer in numbers, and he allowed the exhausted and panic-stricken fugitives to find refuge in Washington.

This routing of Banks frightened Washington again, and McDowell was hastily called from Fredericksburg to the defense of the capital. This was the very thing for which the Confederates had planned, since it kept those reinforcements away from McClellan, who was ordered by President Lincoln to attack at once or give up his plan. Still cautious and wishing to feel every foot of the way, McClellan pushed a reconnaissance in the direction of Hanover Court-House.

When fire was opened on the Confederates most of them fell back to Richmond. General Jo Johnston, perceiving that the Union army was divided by the swollen Chickahominy, quickly took advantage of it, and prepared to hurl a force of 50,000 against the Union corps, which numbered a little more than half as many. A violent rain so interfered with his plans that 10,000 of his troops were unable to take part in the battle. In the disjointed struggle which followed, the Confederates were successful at what is known as the battle of Seven Pines, but were defeated at Fair Oaks. Both were fought on June 1st.

GENERAL LEE BECOMES CONFEDERATE COMMANDER.

In the fighting on the morrow, General Johnston, while directing the attack of the right, was desperately wounded by an exploding shell, which broke several ribs and knocked him from his horse. General G.W. Smith succeeded him in command, but three days later gave way to General R.E. Lee, who in time became the supreme head of the military forces of the Confederacy, and retained his command to the last.
