Preparations for the great march were made with extreme care. Defective wagons and horses were discarded; the number of heavy guns to be carried along was sixty-five, the remainder having been sent to Chattanooga. The marching army numbered about sixty thousand, five thousand of whom belonged to the cavalry and eighteen hundred to the artillery. The army was divided into two immense wings, the Right, the Army of the Tennessee, commanded by General O. O. Howard, and consisting of the Fifteenth and Seventeenth corps, and the Left, the Army of Georgia, by General Henry W. Slocum, composed the Fourteenth and Twentieth corps. Sherman himself was in supreme command. There were twenty-five hundred wagons, each drawn by six mules; six hundred ambulances, with two horses each, while the heavy guns, caissons, and forges were each drawn by eight horses. A twenty days' supply of bread, forty of coffee, sugar, and salt was carried with the army, and a large herd of cattle was driven on foot. In Sherman's general instructions it was provided that the army should march by four roads as nearly parallel as possible, except the cavalry, which remained under the direct control of the general commanding. The army was directed "to forage liberally on the country," but, except along the roadside, this was to be done by organized foraging parties appointed by the brigade commanders. Orders were issued forbidding soldiers to enter private dwellings or to commit any trespass. The corps commanders were given the option of destroying mills, cotton-gins, and the like, and where the army was molested in its march by the burning of bridges, obstructing the roads, and so forth, the devastation should be made "more or less relentless, according to the measure of such hostility." The cavalry and artillery and the foraging parties were permitted to take horses, mules, and wagons from the inhabitants without limit, except that they were to discriminate in favor of the poor. It was a remarkable military undertaking, in which it was intended to remove restrictions only to a sufficient extent to meet the requirements of the march. The cavalry was commanded by General Judson Kilpatrick, who, after receiving a severe wound at Resaca, in May, had gone to his home on the banks of the Hudson, in New York, to recuperate, and, against the advice of his physician, had joined the army again at Atlanta.
