The following official reports were received this evening from Gen. THOMAS, dated at his headquarters near Franklin: HEADQUARTERS DEPARTMENT OF THE CUMBERLAND, NEAR FRANKLIN, Tenn., Dec. 17, 1864. A report just received from Major-Gen. WILSON, states that at 6 P.M. to-day he attacked and dispersed STEVENSON’s division of rebel infantry and a brigade of cavalry, capturing three guns. The Fourth United States Cavalry and HATCH’s division of cavalry, handsomely supported by KNIPE’s division of cavalry, did the work, making several beautiful charges, breaking the rebel infantry in all directions. Had it only been light, the rebel rear guard would have been entirely destroyed. As it is, it has been severely punished. The whole army will continue vigorous pursuit in the morning. This attack was made six miles beyond Franklin. (Signed,) GEORGE H. THOMAS, Major-General.
HEADQUARTERS DEPARTMENT OF CUMBERLAND, NEAR FRANKLIN, Tenn., Dec. 17 — 8 P.M. We have pressed the enemy to-day beyond Franklin, capturing his hospitals, containing over 1,500 wounded and about 150 of our wounded, in addition to the above. Gen. KNIFE, commanding a division of cavalry, drove the enemy’s rear guard through Franklin to-day, capturing about 250 prisoners and five battle-flags, with very little loss on our side. Citizens of Franklin represent HOOD’s army as completely demoralized. In addition to the captures of yesterday, reported in my dispatches of last night, I have the honor to report the capture of Gen. RUCKER and about two hundred and fifty prisoners of the enemy’s cavalry, in a fight that occurred about 8 o’clock last night between Gen. RUCKER and Gen. HATCH, of our cavalry. The enemy has been pressed to-day both in front and on both flanks. Brig.-Gen. JOHNSON succeeded in striking him on the flank just beyond Franklin, capturing quite a number of prisoners — number not yet reported. My cavalry is pressing him closely through, and I am very much in hopes of getting many more prisoners to-morrow. (Signed) Geo. H. THOMAS, Maj.-Gen.
Other dispatches (unofficial) from Nashville, state that 1,000 prisoners were captured by WILSON, and that Gen. ROUSSEAU, commanding at Murfreesboro, reports FORREST killed and 1,500 of his men captured. The Superintendent at Nashville reports that the railroad from Nashville will be open to Franklin to-night, and will rapidly follow THOMAS, thus furnishing him supplies, and enabling him to push on after HOOD. EDWIN M. STANTON, Secretary of War.
