To oppose this vast army Lee had less than 65,000 men in the Army of Northern Virginia and the only other formidable Confederate force in the field was that commanded by General Joseph Johnston, who, with some 53,000 men, was stationed in Georgia guarding the cotton states and the far South. If these two armies could be captured or destroyed, all organized resistance to the Union would be at an end, and Grant, accordingly, determined to throw his entire weight upon them, sending Sherman against Johnston, Butler against the City of Richmond and Sigel against the rich Shenandoah Valley which supplied the Confederate armies with food, while he himself attacked Lee with an overwhelming force. Never before had a Union general undertaken a campaign covering such a vast extent of country and never before had such a united effort been made to exhaust the armies and the resources of the South. With his own forces threatened by superior numbers Lee would not be able to reënforce Johnston with safety and, confronted by Sherman, Johnston would find it impossible to send assistance to Lee. This promised to bring the war to a speedy close, and the supporters of the Union redoubled their praises of the Lieutenant-General as they began to understand his plan. Indeed, the more he avoided publicity and applause and the more indifference he showed for popular opinion, the more the newspapers and the general public fawned upon him, and when, on May 3, 1864, he ordered his armies to advance, the whole North was fairly aflame with enthusiasm. It was certainly a momentous occasion. Three years earlier Grant had been utterly unknown to the country at large and the small group who acknowledged his acquaintance had regarded him as a rather pitiful failure, while the Government to whom he had offered his services had ignored him altogether. Now, at his nod, hundreds of thousands of men instantly sprang to arms and the most powerful armies that America had ever seen moved forward in obedience to his will, Sherman marching southward, Butler creeping toward Richmond, Sigel advancing into the fertile Shenandoah Valley, and the Army of the Potomac crossing the Rapidan River to renew its struggle with Lee. Lee had watched the elaborate preparations of his new antagonist with keen interest and no little apprehension, for Grant's record as a fighting man promised a duel to the death and the South had no more men.
