But the General Assembly of Virginia, passionately seconded by the City Council, petitioned the Government to stand its ground "till not a stone was left upon another." Every man in Richmond who could do a hand's turn and who was not already in arms marched out to complete the defenses of the James at Drewry's Bluff. Senators, bankers, bondmen and free, merchants, laborers, and ministers of all religions, dug earthworks, hauled cannon, piled ammunition, or worked, wet to the waist, at the big boom that was to stop the ships and hold them under fire. The Government had changed its mind. Richmond was to be held to the last extremity. And the Southern women were as willing as the men. In the midst of all this turmoil Lee calmly reviewed the situation. He saw that the Federal gunboats coming up the James were acting alone, as the disconnected vanguard of what should have been a joint advance, and that no army was yet moving to support them. He knew McClellan and Banks and read them like a book. He also knew Jackson, and decided to use him again in the Shenandoah Valley as a menace to Washington. Writing to him on the sixteenth of May, the very day McClellan reached White House, only twenty miles from Richmond, he said: "Whatever movement you make against Banks, do it speedily, and, if successful, drive him back towards the Potomac, and create the impression, as far as possible, that you design threatening that line." Moreover, out of his own scanty forces, he sent Jackson two excellent brigades. Thus, while the great Federal civilians who knew nothing practical of war were all agog about Richmond, a single point at one end of the semicircle, the great Confederate strategist was forging a thunderbolt to relieve the pressure on it by striking the Federal center so as to threaten Washington. The fundamental idea was a Fabian defensive at Richmond, a vigorous offensive in the Valley, to produce Federal dispersion between these points and Washington; then rapid concentration against McClellan on the Chickahominy. The unsupported Federal gunboats were stopped and turned back at the boom near Drewry's Bluff. McClellan, bent on besieging Richmond in due form, crawled cautiously about the intervening swamps of the oozy Chickahominy. McDowell, who could not advance alone, remained at Fredericksburg. Shields stood behind him, near Catlett's Station, to keep another eye on nervous Washington.
