When the rebel military line already mentioned, running lengthwise of the State of Kentucky, was broken up by Grant's getting through and behind it at Fort Donelson, the rebel leaders sought to hold another east and west line, coinciding nearly with the southern line of Tennessee, along the important Memphis and Charleston Railroad, and their commander in the West, Albert Sydney Johnston, set about concentrating his forces at Corinth, on that road. Halleck, by this time commanding the whole Department of the Mississippi, now prepared to attack Corinth. It was with this design that Grant's army was sent up the Tennessee, and encamped at Shiloh. But the rebels did not wait to be attacked. They advanced themselves, with the bold and judicious design of beating the army at Shiloh, and then of marching northward, regaining all the ground they had lost, and retaliating by an invasion of the States north of the Ohio. This hardy attempt was well nigh successful. The night before the battle of Shiloh, Beauregard, as the rebel council of war separated, had prophesied: "To-morrow night we sleep in the enemy's camp." The sudden and vehement assault of the morning, maintained with tremendous and pertinacious fury all day long, had steadily crushed the Union army backward towards the Tennessee river, until towards sunset it had been pounded into a heterogeneous, irregular line of desperate fighters, and behind them a great mass of terrified and disheartened runaways, hiding under the river bank. What the heathen called Fortune, what Christians recognize as an overruling Providence, caused a conjuncture of circumstances by which, between night and morning, the relative number and spirits of the troops on both sides, and the result of the fight, were totally reversed. These circumstances were, the powerful resistance offered, at the end of the Sunday's disastrous fight, to the final charges of the rebels, by the artillery massed at the left end or key of the Union position, close to the river; by the further obstacle of a ravine stretching back from the river before the Union lines just at that point; by the powerful effect of the monstrous shells sent up this ravine and into the rebel lines from the two Union gunboats, Tyler and Lexington; and finally, by the coming upon the field of the advance of Buell's army. Beauregard's men slept in the Union camp, as he had said, but during the night Buell's troops and Gen. Lewis Wallace's division came upon the field. Monday morning, instead of last night's picture of 30,000 rebels, flushed with all day's victory, against at most 23,000 disorganized and all but overpowered Union troops, the daylight broke on a Union army of 50,000, being Grant's 23,000, somewhat refreshed and reorganized, and entirely inspirited; and 27,000 reinforcements, fresh and unbroken; while the rebel army, exhausted by its own efforts, had received no increase, had lost by stragglers, had
