In the estimate of time, Sherman had no right to disregard even Thomas's well-known "slowness of thought and action," but was bound to take that into account.

I have never yet been able to see the wisdom of taking any hazard of defeat in Tennessee when we had ample force at command to secure victory there, with enough remaining to march wherever its commander pleased through the South, except where Hood's or Lee's army might be. By this I mean to say that three, or even two, of Sherman's corps could have gone to Savannah, or anywhere else, just as well as four, and thus have left Thomas force enough to make the defeat of Hood sure beyond contingency; or that Sherman should have delayed his march to the sea until Thomas had concentrated troops enough to defeat Hood.

THE MILITARY THEORY ON WHICH IT WAS BASED

The question which now presents itself for critical consideration is, Upon what military theory was Sherman's "march to the sea" based?

Sherman himself explains it as a change of base, and he estimates its value in comparison with that of his subsequent operations in the ratio of one to ten. But why those subsequent operations, or a change of base with a view to any such ulterior purpose? Grant had not at that time even suggested the need of Sherman's aid against Lee, and events proved that no such need existed. When Sherman started for Savannah from Atlanta, the Confederate force in the Gulf States was quite equal to Lee's army in Virginia, while Grant's army was larger than Sherman's. Could Sherman have contemplated at that time such a thing as going to Grant's assistance, where he was not needed, and leaving Hood's army behind him?

A change of base to Savannah or Mobile had been contemplated as a probable necessity of future operations in Georgia or in the Gulf States, upon the capture of Atlanta; but that of course upon the supposition that there would still be a formidable army of the Confederacy in those States against which operations were to be conducted. When that Confederate army, under Hood, marched toward the west, with the evident intention to carry the war into Tennessee and Kentucky, why a change of base by Sherman in the opposite direction, to Savannah?

Sherman appears to have supposed at first that Hood would follow him when he started on his march through Georgia, as Hood had supposed that Sherman would follow him into Tennessee. Was there any more reason for the one supposition than the other? Ought not Sherman as well as Hood to have known his antagonist better than such a supposition would imply? Was it not extremely unreasonable to suppose that Hood, after he had marched hundreds of miles west from Atlanta and reached the base of his projected operations in Tennessee, would turn back and follow Sherman at such a distance in his rear? It is perfectly evident that such a stern-chase by Hood was contemplated only as a bare possibility, not by any means as a probable result of Sherman's march. It could have had no influence in forming Sherman's final determination to make that march. In fact, the march does not appear to have been finally decided on—certainly it was not commenced—until Hood had gone so far in the opposite direction as to make his pursuit of Sherman out of the question, and had fully disclosed his plan to invade Tennessee. It was surely, therefore, an extraordinary spectacle to see the main Union army marching where there was no considerable hostile force to meet it, leaving a comparatively small detachment to cope with the formidable enemy!

Of course Sherman could not fall back into Tennessee, and thus let Hood put him on the defensive, even for a short time. He could afford only to send back a detachment large enough to enable Thomas, with the other forces he could assemble, to hold Nashville and prevent Hood from crossing the Cumberland. This is virtually but little more than what Sherman did in that regard.

THE MILITARY THEORY ON WHICH IT WAS BASED

There then remained to Sherman practically only one line of action at all consistent with the dictates of established principles in the conduct of a military campaign: That was to strike with his superior remaining force for Hood's rear, south of the Tennessee River. Such a movement could have been commenced immediately upon Hood's march in that direction. Supplies would have been drawn, first from Chattanooga, and afterward from Stevenson, and then from Decatur, Sherman's line of supply being thus very much shortened. A small detachment at Atlanta could have destroyed the works of military value in that place, and the railroad thence back to Chattanooga, being completely covered in this work by Sherman's army, without delaying its march a single day. Sherman could thus have easily struck Hood south of the Tennessee before the latter could have made his preparations for crossing that river. Indeed, with Sherman marching in that direction, even so bold a man as Hood could hardly have been so reckless as to have crossed the Tennessee; and if he had, his destruction must have been sure. Hence the least result would have been simply to transfer the theater of operations from Georgia to Alabama, or perhaps to Mississippi, and greatly to shorten Sherman's line of supply. And what possible difference could it make in which part of the revolted States the theater of war might be, so long as the Confederate army, to destroy which was the only important object of a campaign, was there? To avoid a transfer of the battlefield from Georgia to Alabama or Mississippi, was it wise to run the risk of transferring it to Kentucky or Ohio? Perhaps no movement which could have been contemplated by the Confederate authorities would have been more greatly to Sherman's advantage over Hood than the one they adopted.
