Landing and on the same side of the river. General Buell, in command of the Army of the Ohio, about 36,000 strong, was marching toward Savannah to join Grant in an offensive movement against the Confederates, who were at or near Corinth.
Albert Sidney Johnston, grieved as he was over the disaster at Donelson, was always cheered by the support and friendship of Jefferson Davis, who wrote to him, My confidence in you has never wavered.1 Beauregard, then the idol of the South, had been persuaded to leave Virginia and go to the Southwest to the aid of Johnston in the hope that, by his personal popularity, he might succeed in arousing the people to resist the invasion of their territory.2 Through the exertions of these two, an army of 40,000 was collected at Corinth. What the people want, said Johnston, is a battle and a victory; and he hoped to crush Grant before Buell could join him. Leaving Corinth3 on April 3, with the idea of surprising the Union forces, he expected to make the attack two days later, but owing to a number of delays, was unable to deliver the blow until the early morning of Sunday, April 6.
On the eve of this battle, called Shiloh, Grants remarkable faculty of divining the enemys movements, displayed at Donelson and later during his military career, seemed to be utterly in abeyance. Grant never studied the opposing commander with the thoroughness of Lee, and this time he failed to guess that desperation would drive Johnston to the offensive. He had made up his mind that the enemy would await his attack and so obstinate was he in this belief as to ignore certain unmistakable signs of a projected movement.
