Between the Oostanaula and the Etowah was the most open portion of northern Georgia, and it was possible for Sherman to move his army southward in several columns of pursuit on parallel roads (such as they were) without extending his front over a width of more than eight or ten miles. He was eager to bring the Confederates to battle in this region, and urged his subordinates to make haste. The assignment of routes to the different columns gave the centre to General Thomas, following the railroad in general, but putting his three corps upon as many country roads, when they could be found. General Schofield with the Twenty-third Corps was ordered to get over to the old Federal road which runs through Spring Place (east of Dalton) to Cassville. General McPherson with his two corps was sent by the Rome road and such parallel road as might be available, keeping communication with the centre. [Footnote: Official Records, vol. xxxviii. pt. iv. p. 216.] Beyond him, on the extreme right, Davis's division of the Cumberland Army supported Garrard's cavalry division in a movement upon Rome by the west side of the Oostanaula. [Footnote: _Id_., pp. 198, 202-204.] The object of the last-mentioned movement was the destruction of the Confederate machine-shops and factories at Rome, as well as to cover the flank against movements along the main route of travel from Alabama. The extreme left flank was to be covered by the cavalry of the Ohio Army under General Stoneman. In making such an advance, success as well as comfort depends upon the care with which the several columns are led, so that each shall keep its place, progressing equally with the others, and avoid above all things cutting into and interrupting those moving on its right or left. Each must keep the common purpose in view, and avoid obstructing the rest, for nothing is more wearisome to the troops and ruinous to the plans of the commander than to have the lines of advance cross each other. In our march of the 17th our own corps was fated to feel the full annoyance and delay of such an interference. General Thomas ordered Howard's corps to cross by the bridges at Resaca, followed by Palmer's, which was diminished by the absence of Davis's division. He also ordered Hooker's corps to march by the long neck between the Oostanaula and Connasauga rivers to Newtown, and cross the Oostanaula there. Hooker would then follow such roads as he could find within two or three miles of Howard's line of march toward Adairsville. Sherman and Thomas both were with Howard.
