On the 7th of September I learned of the advance of Van Dorn and Price, apparently upon Corinth. One division was brought from Memphis to Bolivar to meet any emergency that might arise from this move of the enemy. I was much concerned because my first duty, after holding the territory acquired within my command, was to prevent further reinforcing of Bragg in Middle Tennessee. Already the Army of Northern Virginia had defeated the army under General Pope and was invading Maryland. In the Centre General Buell was on his way to Louisville and Bragg marching parallel to him with a large Confederate force for the Ohio River.
I had been constantly called upon to reinforce Buell until at this time my entire force numbered less than 50,000 men, of all arms. This included everything from Cairo south within my jurisdiction. If I too should be driven back, the Ohio River would become the line dividing the belligerents west of the Alleghanies, while at the East the line was already farther north than when hostilities commenced at the opening of the war. It is true Nashville was never given up after its first capture, but it would have been isolated and the garrison there would have been obliged to beat a hasty retreat if the troops in West Tennessee had been compelled to fall back. To say at the end of the second year of the war the line dividing the contestants at the East was pushed north of Maryland, a State that had not seceded, and at the West beyond Kentucky, another State which had been always loyal, would have been discouraging indeed. As it was, many loyal people despaired in the fall of 1862 of ever saving the Union. The administration at Washington was much concerned for the safety of the cause it held so dear. But I believe there was never a day when the President did not think that, in some way or other, a cause so just as ours would come out triumphant.
Up to the 11th of September Rosecrans still had troops on the railroad east of Corinth, but they had all been ordered in. By the 12th all were in except a small force under Colonel Murphy of the 8th Wisconsin. He had been detained to guard the remainder of the stores which had not yet been brought in to Corinth.
