In the meantime Grant was busier with his own pressing problems of organization for an advance than with any idea of resisting attack. He lacked the prevision of Winfield Scott and Lee, both of whom expected from the first that the war would last for years. His own expectation up to this had been that the South would collapse after the first smashing blow, and that its western armies were now about to be dealt such a blow. He was not unmindful of all precautions; for he knew the Confederates were stirring on his front. Yet he went downstream to Savannah without making sure that his army was really safe at Shiloh. Pittsburg Landing was at the base of the Shiloh position. But the point at which, by the original orders, Buell was to join was Savannah, nine miles north along the Tennessee. So Grant had to keep in touch with both. He had not ignored the advantage of entrenching. But the best line for entrenching was too far from good water; and he thought he chose the lesser of two evils when he devoted the time that might have been used for digging to drilling instead. His army was raw as an army; many of the men were still rawer recruits; and, as usual, the recruiting authorities had sent him several brand-new battalions, which knew nothing at all, instead of sending the same men as reinforcements to older battalions that could "learn 'em how." Grant's total effectives at first were only thirty-three thousand. This made the odds five to four in favor of Johnston's attack. But the rejoining of Lew Wallace's division, the great reinforcement by Buell's troops, and the two ironclad gunboats on the river, raised Grant's final effective grand total to sixty thousand. The combined grand totals therefore reached a hundred thousand--double the totals at Donelson and far exceeding those at Bull Run. After a horrible week of cold and wet the sun set clear and calm on Saturday, the eve of battle. The woods were alive with forty thousand Confederates all ready for their supreme attack on the thirty-three thousand Federals on their immediate four-mile front. Grant's front ran, facing south, between Owl and Lick Creeks, two tributaries that joined the Tennessee on either side of Pittsburg Landing. Buell's advance division, under Nelson, was just across the Tennessee. But Grant was in no hurry to get it over. His reassuring wire that night to Halleck said: "The main force of the enemy is at Corinth. I have scarcely the faintest idea of an attack (general one) being made upon us." But the skirmishing farther south on Friday had warned Grant, as well as Sherman and the vigilant Prentiss, that Johnston might be trying a reconnaissance in force--the very thing that Beauregard wished the Confederates to do.
