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.
I cannot better show my own exact impression at the time respecting the operations of Sherman and Hood in 1864, than by an illustration that will be at once appreciated on every farm in America. When two fighting-cocks meet for the first time, battle is joined without delay, and is prosecuted with all possible vigor and skill. If the result is decisive the victor’s triumph is loudly proclaimed, while the defeated combatant, with lowered crest, seeks safety in flight. If, on the contrary, the result is a drawn battle, the two antagonists, as if by common consent, slowly separate, carrying their heads high, and sharply watching each other. When distance has assured the close of that contest, they severally go to feeding, as if nothing unusual had happened, or else march off to seek some less formidable foe. Neither utters a note of defiance until he is well beyond the other’s reach.
The correspondence between Grant and Sherman, especially the letters from Grant of September 12, and from Sherman of September 20, both carried by Grant’s staff officer, Colonel Horace Porter, show a complete understanding of the situation at that time, and perfect accord in respect to the operations appropriate to that situation.( 2) Savannah was to be captured, if practicable, by military and naval forces from the east, and Sherman was so to manoeuver in respect to Hood’s army as to swing round the latter and thus place himself in position to open communication with Savannah as his new base. This was the simple, logical plan dictated by the situation, which had for a long time been considered and worked out after weighing all the advantages and disadvantages of other possible plans.
But very soon after Sherman despatched his letter of September 20 by Colonel Porter, Hood commenced his movement to Sherman’s rear, and then far to the west, which was designed to and did radically change the military situation in view of which the carefully matured plan described in Sherman’s letter of September 20 had been formed. Sherman, as clearly appears from his despatches later than September 20, considered long and apparently with great doubt what change ought to be made in his own plans in consequence of the altered situation due to the unexpected movements of his enterprising adversary. That some very important change in Sherman’s plans was imperative was a matter of course. A general cannot well make his own plans entirely upon his own theory as to what his enemy will or ought to do, but must be governed in some measure by what the other actually does. General Sherman evidently perceived quite clearly what established rules of action required to be done, and General Grant even more clearly, as was shown in his despatches of October 11, 1864, and others.
