Nothing occurred to interrupt our progress, and, on the evening of June 13, I rejoined McCook's division headquarters at Iuka.
Buell's new movement, it will be remembered, was the occupation of the important strategic point, Chattanooga, and the liberation of East Tennessee. But, in addition to general instructions to this effect from Halleck, he also received a specific order to put the line of the Memphis & Charleston Railroad along his route of march in running order, and to maintain it by proper military protection. The distance from Corinth to Chattanooga is 217 miles, and should have been easily traversed by the army in from twenty-five to thirty-five days. General Buell always claimed that, in a personal interview with Halleck on the 11th, he requested to be permitted to choose his own route, his preference being in favor of a line of march through middle Tennessee via McMinnville, but that the order to repair the road and use it as a line of supply was insisted upon. An issue subsequently arose between Buell and Halleck as to the latter's responsibility for this. But, whatever the facts were, it can hardly be disputed that the coming failures of the Army of the Ohio were mainly due to the delays and other injurious effects of the efforts to repair and run the railroad in question. Fully two months were spent by half of the army in opening and holding it to Decatur, only to find that its regular operation could not be maintained, as it ran parallel to the front of the enemy, and hence was peculiarly exposed to interruption. Moreover, it proved impossible to stock it with sufficient motive-power and cars in time to do much good to Buell's forces. The work on the road resulted, too, in scattering the army a good deal, and demoralized the troops by keeping them from their regular military duties. The detention no doubt caused the miscarriage of the general plan for the campaign and the extraordinary turn of events which was to lead the Army of the Ohio, not to East Tennessee, but back to the river whose name it bore.
