Soon after daybreak, Sunday the 16th, the men of Lauman's brigade heard the notes of a bugle advancing from the fort. It announced an officer, who bore to General Grant a letter from General Buckner, proposing the appointment of commissioners to agree upon terms of capitulation, and also proposing an armistice until noon. General Grant replied, acknowledging the receipt of the letter, and adding: "No terms except an unconditional and immediate surrender can be accepted. I propose to move immediately upon your works." Buckner replied: "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." White flags were displayed along the works; the National troops marched in, and General Grant at once made the following order: "All prisoners taken at the surrender of Fort Donelson will be collected as rapidly as practicable near the village of Dover, under their respective company and regimental commanders, or in such manner as may be deemed best by Brigadier-General S.B. Buckner, and will receive two days' rations preparatory to embarking for Cairo. Prisoners are to be allowed their clothing, blankets, and such private property as may be carried about the person, and commissioned officers will be allowed their side-arms." There is disagreement as to the number of guns captured. There were thirteen in the water-batteries and eight in the fort. Besides, there were eight artillery companies, whose field-pieces were disposed in nine positions along the line of intrenchments. Six of these companies were those of Maney, Porter, Graves, Green, Guy, Jackson. The other two are called Ross and Murray in the account in the Nashville _Patriot_, and called Parker and French on the pen-sketch of the works showing the position of the light batteries, found among the Confederate records. The number of pieces in these batteries is not given. Badeau gives the number of guns surrendered at sixty-five, and no reason is seen why that is not correct.
