The fall of Atlanta was a heavy blow to the Confederates. They had, during the war, transformed it into a city of mills, foundries, and workshops, from which they drew supplies, ammunition, and equipments, and upon which they depended largely for the manufacture and repair of arms. But perhaps even more important than the military damage to the South resulting from its capture, was its effect upon Northern politics. Until then the presidential campaign in progress throughout the free States was thought by many to involve fluctuating chances under the heavy losses and apparently slow progress of both eastern and western armies. But the capture of Atlanta instantly infused new zeal and confidence among the Union voters, and from that time onward, the reëlection of Mr. Lincoln was placed beyond reasonable doubt.
Sherman personally entered the city on September 8, and took prompt measures to turn it into a purely military post. He occupied only the inner line of its formidable defenses, but so strengthened them as to make the place practically impregnable. He proceeded at once to remove all its non-combatant inhabitants with their effects, arranging a truce with Hood under which he furnished transportation to the south for all those whose sympathies were with the Confederate cause, and sent to the north those who preferred that destination. Hood raised a great outcry against what he called such barbarity and cruelty, but Sherman replied that war is war, and if the rebel families wanted peace they and their relatives must stop fighting.
"God will judge us in due time, and he will pronounce whether it be more humane to fight with a town full of women, and the families of a brave people at our back, or to remove them in time to places of safety among their own friends and people."
Up to his occupation of Atlanta, Sherman's further plans had neither been arranged by Grant nor determined by himself, and for a while remained somewhat undecided. For the time being, he was perfectly secure in the new stronghold he had captured and completed. But his supplies depended upon a line of about one hundred and twenty miles of railroad from Atlanta to Chattanooga, and very near one hundred and fifty miles more from Chattanooga to Nashville. Hood, held at bay at Lovejoy's Station, was not strong enough to venture a direct attack or undertake a siege, but chose the more feasible policy of operating systematically against Sherman's long line of communications. In the course of some weeks both sides grew weary of the mere waste of time and military strength consumed in attacking and defending railroad stations, and interrupting and reëstablishing the regularities of provision trains. Toward the end of September, Jefferson Davis visited Hood, and in rearranging some army assignments, united Hood's and an adjoining Confederate department under the command of Beauregard; partly with a view to adding the counsels of the latter to the always energetic and bold, but sometimes rash, military judgment of Hood.
Between these two Hood's eccentric and futile operations against Sherman's communications were gradually shaded off into a plan for a Confederate invasion of Tennessee. Sherman, on his part, finally matured his judgment that instead of losing a thousand men a month merely defending the railroad, without other advantage, he would divide his army, send back a portion of it under the command of General Thomas to defend the State of Tennessee against the impending invasion; and, abandoning the whole line of railroad from Chattanooga to Atlanta, and cutting entirely loose from his base of supplies, march with the remainder to the sea; living upon the country, and "making the interior of Georgia feel the weight of war." Grant did not immediately fall in with Sherman's suggestion; and Sherman prudently waited until the Confederate plan of invading Tennessee became further developed. It turned out as he hoped and expected. Having gradually ceased his raids upon the railroad, Hood, by the end of October, moved westward to Tuscumbia on the Tennessee River, where he gathered an army of about thirty-five thousand, to which a cavalry force under Forrest of ten thousand more was soon added.
Under Beauregard's orders to assume the offensive, he began a rapid march northward, and for a time with a promise of cutting off some advanced Union detachments. We need not follow the fortunes of this campaign further than to state that the Confederate invasion of Tennessee ended in disastrous failure. It was severely checked at the battle of Franklin on November 30; and when, in spite of this reverse, Hood pushed forward and set his army down before Nashville as if for attack or siege, the Union army, concentrated and reinforced to about fifty-five thousand, was ready. A severe storm of rain and sleet held the confronting armies in forced immobility for a week; but on the morning of December 15, 1864, General Thomas moved forward to an attack in which on that and the following day he inflicted so terrible a defeat upon his adversary, that the Confederate army not only retreated in rout and panic, but soon literally went to pieces in disorganization, and disappeared as a military entity from the western conflict.
Long before this, Sherman had started on his famous march to the sea. His explanations to Grant were so convincing, that the general-in-chief, on November 2, telegraphed him: "Go on as you propose." In anticipation of this permission, he had been preparing himself ever since Hood left him a clear path by starting westward on his campaign of invasion. From Atlanta, he sent back his sick and wounded and surplus stores to Chattanooga, withdrew the garrisons, burned the bridges, broke up the railroad, and destroyed the mills, foundries, shops and public buildings in Atlanta. With sixty thousand of his best soldiers, and sixty-five guns, he started on November 15 on his march of three hundred miles to the Atlantic. They carried with them twenty days' supplies of provisions, five days' supply of forage, and two hundred rounds of ammunition, of which each man carried forty rounds.
With perfect confidence in their leader, with perfect trust in each others' valor, endurance and good comradeship, in the fine weather of the Southern autumn, and singing the inspiring melody of "John Brown's Body," Sherman's army began its "marching through Georgia" as gaily as if it were starting on a holiday. And, indeed, it may almost be said such was their experience in comparison with the hardships of war which many of these veterans had seen in their varied campaigning. They marched as nearly as might be in four parallel columns abreast, making an average of about fifteen miles a day. Kilpatrick's admirable cavalry kept their front and flanks free from the improvised militia and irregular troopers of the enemy. Carefully organized foraging parties brought in their daily supply of miscellaneous provisions—corn, meat, poultry, and sweet potatoes, of which the season had yielded an abundant harvest along their route.
The Confederate authorities issued excited proclamations and orders, calling on the people to "fly to arms," and to "assail the invader in front, flank, and rear, by night and by day." But no rising occurred that in any way checked the constant progress of the march. The Southern whites were, of course, silent and sullen, but the negroes received the Yankees with demonstrations of welcome and good will, and in spite of Sherman's efforts, followed in such numbers as to embarrass his progress. As he proceeded, he destroyed the railroads by filling up cuts, burning ties, heating the rails red hot and twisting them around trees and into irreparable spirals. Threatening the principal cities to the right and left, he marched skilfully between and past them.
He reached the outer defenses of Savannah on December 10, easily driving before him about ten thousand of the enemy. On December 13, he stormed Fort McAllister, and communicated with the Union fleet through Ossabaw Sound, reporting to Washington that his march had been most agreeable, that he had not lost a wagon on the trip, that he had utterly destroyed over two hundred miles of rails, and consumed stores and provisions that were essential to Lee's and Hood's armies. With pardonable exultation General Sherman telegraphed to President Lincoln on December 22:
