The total loss of the Confederate army is not definitely stated. General Gideon J. Pillow says, in his report, that in killed and wounded it was about two thousand. With regard to the number of Confederates captured, General Grant says in his "Memoirs": "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." But General Buckner says, in his official report, that "the aggregate of the army, never greater than 12,000, was now reduced to less than 9000 after the departure of General Floyd's brigade."
