I am, sir, very respectfully, Your ob't se'v't, S. B. BUCKNER, Brig. Gen. C. S. A.
To Brigadier-General U. S. Grant, Com'ding U. S. Forces, Near Fort Donelson.
To this I responded as follows:
HEADQUARTERS ARMY IN THE FIELD, Camp near Donelson, February 16, 1862.
General S. B. BUCKNER, Confederate Army.
SIR:--Yours of this date, proposing armistice and appointment of Commissioners to settle terms of capitulation, is just received. No terms except an unconditional and immediate surrender can be accepted. I propose to move immediately upon your works.
I am, sir, very respectfully, Your ob't se'v't, U. S. GRANT, Brig. Gen.
To this I received the following reply:
HEADQUARTERS, DOVER, TENNESSEE, February 16, 1862.
To Brig. Gen'I U. S. GRANT, U. S. Army.
SIR:--The distribution of the forces under my command, incident to an unexpected change of commanders, and the overwhelming force under your command, compel me, notwithstanding the brilliant success of the Confederate arms yesterday, to accept the ungenerous and unchivalrous terms which you propose.
I am, sir, Your very ob't se'v't, S. B. BUCKNER, Brig. Gen. C. S. A.
General Buckner, as soon as he had dispatched the first of the above letters, sent word to his different commanders on the line of rifle-pits, notifying them that he had made a proposition looking to the surrender of the garrison, and directing them to notify National troops in their front so that all fighting might be prevented. White flags were stuck at intervals along the line of rifle-pits, but none over the fort. As soon as the last letter from Buckner was received I mounted my horse and rode to Dover. General Wallace, I found, had preceded me an hour or more. I presume that, seeing white flags exposed in his front, he rode up to see what they meant and, not being fired upon or halted, he kept on until he found himself at the headquarters of General Buckner.
I had been at West Point three years with Buckner and afterwards served with him in the army, so that we were quite well acquainted. In the course of our conversation, which was very friendly, he said to me that if he had been in command I would not have got up to Donelson as easily as I did. I told him that if he had been in command I should not have tried in the way I did: I had invested their lines with a smaller force than they had to defend them, and at the same time had sent a brigade full 5,000 strong, around by water; I had relied very much upon their commander to allow me to come safely up to the outside of their works. I asked General Buckner about what force he had to surrender. He replied that he could not tell with any degree of accuracy; that all the sick and weak had been sent to Nashville while we were about Fort Henry; that Floyd and Pillow had left during the night, taking many men with them; and that Forrest, and probably others, had also escaped during the preceding night: the number of casualties he could not tell; but he said I would not find fewer than 12,000, nor more than 15,000.
He asked permission to send parties outside of the lines to bury his dead, who had fallen on the 15th when they tried to get out. I gave directions that his permit to pass our limits should be recognized. I have no reason to believe that this privilege was abused, but it familiarized our guards so much with the sight of Confederates passing to and fro that I have no doubt many got beyond our pickets unobserved and went on. The most of the men who went in that way no doubt thought they had had war enough, and left with the intention of remaining out of the army. Some came to me and asked permission to go, saying that they were tired of the war and would not be caught in the ranks again, and I bade them go.
The actual number of Confederates at Fort Donelson can never be given with entire accuracy. The largest number admitted by any writer on the Southern side, is by Colonel Preston Johnston. He gives the number at 17,000. But this must be an underestimate.
The commissary general of prisoners reported having issued rations to 14,623 Fort Donelson prisoners at Cairo, as they passed that point. General Pillow reported the killed and wounded at 2,000; but he had less opportunity of knowing the actual numbers than the officers of McClernand's division, for most of the killed and wounded fell outside their works, in front of that division, and were buried or cared for by Buckner after the surrender and when Pillow was a fugitive. It is known that Floyd and Pillow escaped during the night of the 15th, taking with them not less than 3,000 men. Forrest escaped with about 1,000 and others were leaving singly and in squads all night. It is probable that the Confederate force at Donelson, on the 15th of February, 1862, was 21,000 in round numbers.
On the day Fort Donelson fell I had 27,000 men to confront the Confederate lines and guard the road four or five miles to the left, over which all our supplies had to be drawn on wagons.
During the 16th, after the surrender, additional reinforcements arrived.
During the siege General Sherman had been sent to Smithland, at the mouth of the Cumberland River, to forward reinforcements and supplies to me. At that time he was my senior in rank and there was no authority of law to assign a junior to command a senior of the same grade. But every boat that came up with supplies or reinforcements brought a note of encouragement from Sherman, asking me to call upon him for any assistance he could render and saying that if he could be of service at the front I might send for him and he would waive rank.
