The effective force of General Grant's army engaged in the battles of April 6th and 7th at Shiloh was 49,314; reënforcements of General Buell, 21,579; total, 70,893. The casualties in the battle of April 6th in Grant's force were as follows: killed, 1,500; wounded, 6,634; missing, 3,086; total, 11,220; leaving, for duty on the 7th, 59,673.
On April 9th Major-General H. W, Halleck left St. Louis and proceeded to Pittsburg Landing to assume command of the enemy's forces in the field. A reorganization was made, in which General Grant's divisions formed the right wing, those of General Buell the center, and those of General Pope, brought from the west side of the Mississippi, the left wing; and an advance on Corinth was commenced.
Corinth, the position from which our forces had advanced to Shiloh or Pittsburg Landing, and to which they had now retired, was a small village in the northeast corner of the State of Mississippi. It was ninety miles east of Memphis and twenty or twenty-two west of the Tennessee River. The Memphis and Charleston Railroad ran from west to east through it, and the Mobile and Ohio road from south to north. The country between it and the Tennessee River was quite rugged, broken into ridges, and covered with a heavy forest. The position itself was flat, the water poor. Being the point at which two principal railroads crossed, it served admirably for the concentration of our forces.
Corinth was a strategic point of importance, and it was intended to be held as long as circumstances would permit; but it was untenable in the face of a largely superior force, owing to the ease with which the railroad communications in the rear could be cut by the enemy's cavalry. The small streams and contiguous flats in its front formed some obstacles which were not passed by the enemy until after the retreat of our army. The defenses were slight, consisting of rifle-pits and earthworks of little elevation or strength.
The movement of General Halleck against this position commenced from Pittsburg Landing on April 28th with a force exceeding eighty-five thousand effectives. On May 3d he had reached within eight miles of Corinth, and on the 21st his batteries were within three miles. This slow progress was probably the result of a conviction that our force was very large, rather than of the bad state of the roads. So great were his precautions, that every night his army lay in an intrenched camp, and by day it was assailed by skirmishers from our army in more or less force.
General Sherman, in his report of May 30th, says:
"My division has constructed seven distinct intrenched camps since leaving Shiloh, the men working cheerfully and well all the time, night and day. Hardly had we finished one camp before we were called on to move forward and build another. But I have been delighted at this feature in the character of my division, and take this method of making it known. Our intrenchments near Corinth and at Russell's, each built substantially in one night, are stronger works of art than the much-boasted forts of the enemy at Corinth."
The line of railroad on the north and east had been cut by the enemy, and an attempt made on the south. But so well was his apprehension of our strength maintained, that he continued his intrenched approaches until within one thousand yards of our main works.
General Sherman says:
