Hooker now marched to where he could see the dome of the court-house at Richmond, but just then McClellan heard that Jackson had been seen in the neighborhood of Hanover Court-House, and so decided to change his base. General McClellan was a man of great refinement, and would never use the same base over a week at a time. He had hardly got the base changed when Lee fell upon his flank at Mechanicsville, June 26, and the Seven Days' battle followed. The Union troops fought and fell back, fought and fell back, until Malvern Hill was reached, where, worn with marching, choked with dust, and broken down by the heat, to which they were unaccustomed, they made their last stand, July 1. Here Lee got such a reception that he did not insist on going any farther. But the Union army was cooped up on the James River. The siege of Richmond had been abandoned, and the North felt blue and discouraged. Three hundred thousand more men were called for, and it seemed that, as in the South, "the cradle and the grave were to be robbed" for more troops. Lee now decided to take Washington and butcher Congress to make a Roman holiday. General Pope met the Confederates August 26, and while Lee and Jackson were separated could have whipped the latter had the Army of the Potomac reinforced him as it should, but, full of malaria and foot-sore with marching, it did not reach him in time, and Pope had to fight the entire Confederate army on that historic ground covered with so many unpleasant memories and other things, called Bull Run. For the second time the worn and wilted Union army was glad to get back to Washington, where the President was, and where beer was only five cents per glass. Oh, how sad everything seemed at that time to the North, and how high cotton cloth was! The bride who hastily married her dear one and bade him good-by as the bugle called him to the war, pointed with pride to her cotton clothes as a mark of wealth; and the middle classes were only too glad to have a little cotton mixed with their woollen clothes. [Illustration: WHERE BEER WAS ONLY FIVE CENTS PER GLASS.] Lee invaded Maryland, and McClellan, restored to command of the Army of the Potomac, followed him, and found a copy of his order of march, which revealed the fact that only a portion of the army was before him. So, overtaking the Confederates at South Mountain, he was ready for a victory, but waited one day; and in the mountains Lee got his troops united again, while Jackson also returned. The Union troops had over eighty thousand in their ranks, and nothing could have been more thoughtful or genteel than to wait for the Confederates to get as many together as possible, otherwise the battle might have been brief and unsatisfactory to the tax-payer or newspaper subscriber, who of course wants his money's worth when he pays for a battle.
