This was the most brilliant, perhaps, of Grant's victories. It is known as the "battle of Missionary Ridge." Hooker had exceeded his prerogative and kept on after capturing the crest of Lookout Mountain, while Sherman was giving the foe several varieties of fits, from the north, when Grant discovered that before him the line was being weakened in order to help the Confederate flanks. So with Thomas he crossed through the first line and over the rifle-pits, forgot that he had intended to halt and reform, and concluded to wait and reform after the war was over, when he should have more time, and that night along the entire line of heights the camp-fires of the Union army winked at one another in ghoulish glee. The army under Bragg was routed, and Bragg resigned his command. Burnside, who had been relieved of the command of the Army of the Potomac, was sent to East Tennessee, where the brave but frost-bitten troops of Longstreet shut him up at Knoxville and compelled him to board at the railroad eating-house there. Sherman's worn and weary boys were now ordered at once to the relief of Burnside, and Longstreet, getting word of it, made a furious assault on the former, who repulsed him with loss, and he went away from there as Sherman approached from the west. [Illustration: "WHERE AM I?"] Hooker had succeeded Burnside in the command of the Army of the Potomac, and he judged that, as Lee was now left with but sixty thousand men, while the Army of the Potomac contained one hundred thousand who craved out-of-door exercise, he might do well to go and get Lee, returning in the cool of the evening. Lee, however, accomplished the division of his army while concealed in the woods and sent Jackson to fall on Hooker's rear. The close of the fight found Hooker on his old camping-ground opposite Fredericksburg, murmuring to himself, in a dazed sort of way, "Where am I?" Lee felt so good over this that he decided to go North and get something to eat. He also decided to get catalogues and price-lists of Philadelphia and New York while there. Threatening Baltimore in order to mislead General Meade, who was now in command of the Federals, Lee struck into Pennsylvania and met with the Union cavalry a little west of Gettysburg on the Chambersburg road. It is said that Gettysburg was not intended by either army as the site for the battle, Lee hoping to avoid a fight, depending as he did on the well-known hospitality of the Pennsylvanians, and Meade intending to have the fight at Pipe Creek, where he had some property. July 1-2-3 were the dates of this memorable battle. The first day was rather favorable to Lee, quite a number of Yankee prisoners being taken while they were lost in the crowded streets of Gettysburg.
