Chancellorsville, to which place the main army of General Hooker was being moved, was not a town, but merely a large farmhouse surrounded by the usual outbuildings. Toward Fredericksburg ten miles distant, the country was somewhat open; but in every other direction it was covered with tall pines and with dense thickets of scrub oaks and many other kinds of trees and flowering plants. This forest, called “the Wilderness,” was about twenty miles long and fifteen broad. It was traversed by two good roads, the Plank road and the old Turnpike; it was along these roads, the possession of which would, of course, be hotly contested by the Federal troops, that General Lee would have to send his forces to attack General Hooker in his strong position at Chancellorsville. But on the night of the first of May, just after the first skirmishing had occurred along these two roads, Stuart brought information that changed the situation decidedly. He rode up about eleven o’clock to an old fallen tree where Lee and Jackson were talking over the plans for the next day, and reported that while Hooker had fortified his position at Chancellorsville on the east, the south, and the southwest, upon the north and the west he had no defences. At the same time, information had been secured concerning an old road by which a circuit could be made around Hooker’s army. Jackson at once conceived the idea of making a forced march by this road so as to attack Hooker in the rear on the next day. Lee agreed, as on this plan seemed to depend their one chance of success. The next morning, General Lee with about 14,000 men remained in front of the Federals on the Plank and Turnpike roads, while Jackson with three divisions marched fifteen miles through the forest and about three o’clock in the afternoon reached the rear of Hooker’s army on the west. General Fitz Lee with the First Virginia cavalry led the advance while the other regiments of cavalry protected the right of Jackson’s line of march. Colonel Munford, commander of one of these regiments, was familiar with this part of the country and rendered valuable service as a guide to Jackson. As Jackson’s command marched first directly south by the Furnace road, Federal scouts, who were spying from the tops of tall pine trees, thought that Lee’s army was in full retreat. They carried this report to Hooker who sent forward two divisions to attack the marching column. By that time, Jackson had turned to the west and, completely screened by trees and undergrowth, was marching rapidly along the old road. The rear of his column, however, was attacked near Catherine Furnace. This attack was soon checked by McLaws, whom Lee sent forward from his small force, and by two regiments sent back by Jackson when he heard the firing in his rear.
