Colonel Bailey's morning report of those present with him on the way from Donelson to Cairo, which included none from hospitals, was, officers and men, 490. There is no report of trustworthy accuracy, giving either the aggregate or the effective strength. Ten thousand five hundred prisoners were put into the charge of Colonel Whittlesey, of the Twentieth Ohio; of which number he sent north, guarded by his own regiment, about six thousand three hundred; another, but much smaller body, was put into the hands of Colonel Sweeney. Besides these, were the wounded and sick in hospital, in camp, and some left on the field. Colonel Whittlesey, at the time, estimated the entire number taken charge of, including sick and wounded, at 13,000. General Floyd said that the boats which carried across and up the river his four Virginia regiments, took at the same time about as many other troops; and he says he took up the river with him 986, officers and men, of the four Virginia regiments. Pillow reported, on March 14th, that several thousand infantry had got out in one way or other, many of whom were at that time with him at Decatur, Ala., and the rest under orders to rendezvous there. They continued slipping out after the surrender. General B.R. Johnson, on the Tuesday after the surrender, not having reported or been enrolled as a prisoner, walked with a fellow-officer out of the intrenchments at mid-day, and, not being challenged, continued beyond the National camps and escaped. The accounts of the escape by boat with Floyd, on horse with Forrest, and by parties slipping out by day and by night through the forest and undergrowth and the devious ravines, fairly show that 5,000 must have escaped. There was scarcely a regiment or battery, if, indeed, there was a single regiment or battery, from which some did not escape. Eleven hundred and thirty-four wounded were sent up the river by boat the evening before the surrender, and General Pillow estimated the killed at over four hundred and fifty. This accounts for an aggregate of over nineteen thousand five hundred, sufficiently near the estimate of nineteen thousand six hundred--the number in the place during the siege, and the additional four hundred, who arrived only in time to be surrendered.
