As I have said already, Johnston was at Dalton, which was nearly one-fourth of the way between Chattanooga and Atlanta. The country is mountainous all the way to Atlanta, abounding in mountain streams, some of them of considerable volume. Dalton is on ground where water drains towards Atlanta and into one of the main streams rising north-east from there and flowing south-west—this being the general direction which all the main streams of that section take, with smaller tributaries entering into them. Johnston had been preparing himself for this campaign during the entire winter. The best positions for defence had been selected all the way from Dalton back to Atlanta, and very strongly intrenched; so that, as he might be forced to fall back from one position, he would have another to fall into in his rear. His position at Dalton was so very strongly intrenched that no doubt he expected, or at least hoped, to hold Sherman there and prevent him from getting any further. With a less skilful general, and one disposed to take no risks, I have no doubt that he would have succeeded.

Sherman's plan was to start Schofield, who was farthest back, a few days in advance from Knoxville, having him move on the direct road to Dalton. Thomas was to move out to Ringgold. It had been Sherman's intention to cross McPherson over the Tennessee River at Huntsville or Decatur, and move him south from there so as to have him come into the road running from Chattanooga to Atlanta a good distance to the rear of the point Johnston was occupying; but when that was contemplated it was hoped that McPherson alone would have troops enough to cope with Johnston, if the latter should move against him while unsupported by the balance of the army. In this he was disappointed. Two of McPherson's veteran divisions had re-enlisted on the express provision that they were to have a furlough. This furlough had not yet expired, and they were not back.

Then, again, Sherman had lent Banks two divisions under A. J. Smith, the winter before, to co-operate with the trans-Mississippi forces, and this with the express pledge that they should be back by a time specified, so as to be prepared for this very campaign. It is hardly necessary to say they were not returned. That department continued to absorb troops to no purpose to the end of the war. This left McPherson so weak that the part of the plan above indicated had to be changed. He was therefore brought up to Chattanooga and moved from there on a road to the right of Thomas—the two coming together about Dalton. The three armies were abreast, all ready to start promptly on time.

Sherman soon found that Dalton was so strongly fortified that it was useless to make any attempt to carry it by assault; and even to carry it by regular approaches was impracticable. There was a narrowing up in the mountain, between the National and Confederate armies, through which a stream, a wagon road and a railroad ran. Besides, the stream had been dammed so that the valley was a lake. Through this gorge the troops would have to pass. McPherson was therefore sent around by the right, to come out by the way of Snake Creek Gap into the rear of the enemy. This was a surprise to Johnston, and about the 13th he decided to abandon his position at Dalton.

On the 15th there was very hard fighting about Resaca; but our cavalry having been sent around to the right got near the road in the enemy's rear. Again Johnston fell back, our army pursuing. The pursuit was continued to Kingston, which was reached on the 19th with very little fighting, except that Newton's division overtook the rear of Johnston's army and engaged it. Sherman was now obliged to halt for the purpose of bringing up his railroad trains. He was depending upon the railroad for all of his supplies, and as of course the railroad was wholly destroyed as Johnston fell back, it had to be rebuilt. This work was pushed forward night and day, and caused much less delay than most persons would naturally expect in a mountainous country where there were so many bridges to be rebuilt.

The campaign to Atlanta was managed with the most consummate skill, the enemy being flanked out of one position after another all the way there. It is true this was not accomplished without a good deal of fighting—some of it very hard fighting, rising to the dignity of very important battles—neither were single positions gained in a day. On the contrary, weeks were spent at some; and about Atlanta more than a month was consumed.

It was the 23d of May before the road was finished up to the rear of Sherman's army and the pursuit renewed. This pursuit brought him up to the vicinity of Allatoona. This place was very strongly intrenched, and naturally a very defensible position. An assault upon it was not thought of, but preparations were made to flank the enemy out of it. This was done by sending a large force around our right, by the way of Dallas, to reach the rear of the enemy. Before reaching there, however, they found the enemy fortified in their way, and there resulted hard fighting for about a week at a place called New Hope Church. On the left our troops also were fortified, and as close up to the enemy as they could get. They kept working still farther around to the left toward the railroad. This was the case more particularly with the cavalry. By the 4th of June Johnston found that he was being hemmed in so rapidly that he drew off and Allatoona was left in our possession.

Allatoona, being an important place, was strongly intrenched for occupation by our troops before advancing farther, and made a secondary base of supplies. The railroad was finished up to that point, the intrenchments completed, storehouses provided for food, and the army got in readiness for a further advance. The rains, however, were falling in such torrents that it was impossible to move the army by the side roads which they would have to move upon in order to turn Johnston out of his new position.

While Sherman's army lay here, General F. P. Blair returned to it, bringing with him the two divisions of veterans who had been on furlough.
