His first battle after restoration to command was an unfortunate one in the beginning, but was turned into a victory. He was advancing on Corinth, Miss., a railroad centre of the Southwest, where a large Confederate army under General Albert Sidney Johnston was collecting. All the available Union forces in the West were gathering to meet it. Grant had selected Pittsburg Landing on the Tennessee River, twenty miles from Corinth, as the place for landing his forces, and Hamburg Landing, four miles up the river, as the starting point for Buell's army in marching on Corinth. Buell was hastening to the rendezvous, coming through Tennessee with a large force. On the 4th of April Grant's horse fell while he was reconnoitring at night, and the general's leg was badly bruised but not broken. Expecting to make an offensive campaign and meet the enemy at Corinth, he had not enjoined intrenchment of the temporary camp. So great was the confidence that Johnston would await attack that the enemy's proximity in force was discovered too late. Johnston led his whole army out of Corinth, and early on the morning of the 6th of April surprised Sherman's division encamped at Shiloh, three miles from Pittsburg Landing, attacking with a largely superior force. The battle raged all day, with heavy losses on both sides, the Union army being gradually forced back to Pittsburg Landing. Five divisions were engaged, three of them composed of raw troops, and many regiments were in a demoralized condition at night. On the next day the Union army, reinforced by Buell's 20,000 men, advanced, attacking the enemy early in the morning, with furious determination. The Confederate forces, although weakened, were determined not to lose the advantage gained, and fought with desperate stubbornness. But it was in vain. A necessity of vindicating their courage was felt by officers and men of the Union Army. They had fully recovered from the effects of the surprise, and pressed forward with zealous assurance. Before the day was done Grant had won the field and compelled a disorderly retreat. In this battle the commander of the Confederate army, General Albert Sidney Johnston, was killed in the first day's fighting, the command devolving on General G. T. Beauregard. On the first day the Union forces on the field numbered about 33,000 against the enemy's above 40,000. On the second day the Union forces were superior. The Union losses in the two days were 1754 killed, 8408 wounded, and 2885 missing; total 13,047. Beauregard reported a total loss of 10,694, of whom 1723 were killed. General Grant says that the Union army buried more of the enemy's dead than is here reported in front of Sherman's and McClernand's divisions alone, and that the total number buried was estimated at 4000.
