Among the many prisoners at Knoxville, were some under like accusation with the two hung at Greeneville: but proceedings against them were more deliberate. They were tried by a court-martial, organized under Gen. Carroll, of Middle Tennessee, successor of Col. Wood at the Post, and by common repute of dissipated habits. For nearly one month, Wm. G. Brownlow was an in-mate of the jail. He states that at the time he was cast into it, the prisoners numbered about one hundred and fifty; that on the lower floor where he was kept, there was not room for all to lie down at one time, and therefore they stood on their feet and rested alternately; that the only article of furniture in the building was a dirty wooden bucket, from which the prisoners drank water with a tin cup; and that their food consisted of meat and bread, scantily supplied, sometimes half raw, sometimes burned. To the truth of his description, in the main, there is extant, corroborative testimony. Some prisoners shook his hand silently with tears; some faces lighted with joy to see him; some manifested a sense of humiliation wrought by their condition, and many were depressed in spirits. A few notes taken from his diary in jail will show the nature and extent of the work carried on by the military towards suspected and convicted Union people: SATURDAY, DEC. 7.--This morning forty of our number under a heavy military escort, were sent off to Tuscaloosa. Thirty-one others arrived to take their places from Cocke, Greene and Jefferson Counties. They bring us tales of woe from their respective counties as to the treatment of Union men and Union families, by the ... cavalry in the rebellion. They are taking all the fine horses they can find and appropriating them to their own use; they are entering houses, breaking open drawers and chests, seizing money, blankets and whatever they can use. MONDAY, DEC. 9.--More prisoners arrived this evening. Twenty-eight are in from Jefferson and Cocke counties. WEDNESDAY, DEC. 11.--Fifteen more prisoners came in to-day from Greene and Hancock counties, charged with having been armed as Union men and accustomed to drill. THURSDAY, DEC. 12.--Fifteen of our prisoners were started to Tuscaloosa this morning to remain there as prisoners of war. They had no trial, but were sent upon their admission that they had been found in arms as Union men, preparing to defend themselves against the assaults and robberies of the so-called Confederate cavalry. Poor fellows! They hated to go. FRIDAY, DEC. 13.--Three more prisoners in to-day from Hancock and Hawkins Counties. Charge as usual--Union men, attached to a company of Home Guards. SATURDAY, DEC. 14.--Three more prisoners from the upper counties were brought in to-day. They speak of the outrages perpetrated by these rebel troops, and of their murderous spirit.
