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.
