except three (one for each separate army), should be permitted to come nearer than Chattanooga; and, moreover, I peremptorily required that all the citizens and families resident in Atlanta should go away, giving to each the option to go south or north, as their interests or feelings dictated.  I was resolved to make Atlanta a pure military garrison or depot, with no civil population to influence military measures.  I had seen Memphis, Vicksburg, Natchez, and New Orleans, all captured from the enemy, and each at once was garrisoned by a full division of troops, if not more; so that success was actually crippling our armies in the field by detachments to guard and protect the interests of a hostile population.

I gave notice of this purpose, as early as the 4th of September, to General Halleck, in a letter concluding with these words: 

If the people raise a howl against my barbarity and cruelty, I will answer that war is war, and not popularity-seeking.  If they want peace, they and their relatives most stop the war.

I knew, of course, that such a measure would be strongly criticised, but made up my mind to do it with the absolute certainty of its justness, and that time would sanction its wisdom.  I knew that the people of the South would read in this measure two important conclusions:  one, that we were in earnest; and the other, if they were sincere in their common and popular clamor “to die in the last ditch,” that the opportunity would soon come.

Soon after our reaching Atlanta, General Hood had sent in by a flag of truce a proposition, offering a general exchange of prisoners, saying that he was authorized to make such an exchange by the Richmond authorities, out of the vast number of our men then held captive at Andersonville, the same whom General Stoneman had hoped to rescue at the time of his raid.  Some of these prisoners had already escaped and got in, had described the pitiable condition of the remainder, and, although I felt a sympathy for their hardships and sufferings as deeply as any man could, yet as nearly all the prisoners who had been captured by us during the campaign had been sent, as fast as taken, to the usual depots North, they were then beyond my control.  There were still about two thousand, mostly captured at Jonesboro, who had been sent back by cars, but had not passed Chattanooga.  These I ordered back, and offered General Hood to exchange them for Stoneman, Buell, and such of my own army as would make up the equivalent; but I would not exchange for his prisoners generally, because I knew these would have to be sent to their own regiments, away from my army, whereas all we could give him could at once be put to duty in his immediate army.  Quite an angry correspondence grew up between us, which was published at the time in the newspapers, but it is not to be found in any book of which I have present knowledge, and therefore is given here, as illustrative of the events referred to, and of the feelings of the actors in the game of war at that particular crisis, together with certain other original letters of Generals Grant and Halleck, never hitherto published.
