HDQRS. SECOND BRIGADE, FIRST CAVALRY DIVISION,
Dandridge, East Tenn., January 17, 1864.
CAPTAIN: I have the honor to report that on the 16th instant the Second Brigade moved forward in advance of the First Division to a point 6 miles northeast from Dandridge on the Morristown road, for the purpose of supporting Colonel Wolford's division, then engaged with the enemy. Colonel Wolford's right having been driven back almost to the town, the command was ordered to return by the same road, and engaged the enemy on the right of the Morristown road and assisted the other troops of the cavalry command in driving back the enemy, who was at one time considerably confused by a vigorous advance of battalions of the Second and Fourth Indiana, and-it was thought that his artillery might have been captured had instructions permitted the bringing forward of proper supports for those battalions. Our loss was 1 man killed and 1 mortally wounded; several horses were also killed. Enemy's loss unknown.
Very respectfully,
O. H. LA GRANGE,
Colonel, Commanding.

Assistant Adjutant-General, First Cavalry Division.

HDQRS. SECOND BRIGADE, FIRST CAVALRY Div., D.C.,
Near Sevierville, Tenn., January 20, 1864.
CAPTAIN: I respectfully report that at 4.30 p.m., on the 17th, a brigade of rebel cavalry under Colonel Harrison attacked one of the pickets of this brigade, which was posted on an eminence to the right of the Morristown road, 2 miles from Dandridge.
As soon as the firing commenced the First Wisconsin was ordered out at a trot, and dismounted at the foot of the wooded hill on which our picket was posted, for the purpose of occupying it before the enemy and holding it against him. He, however, drove back our pickets so rapidly that he was enabled to open a flank fire before the regiment could be brought into action. At this time the remainder of the brigade was ordered out at a trot, but owing to a misunderstanding, for which no blame can attach to any person, did not move at the first order. The First Wisconsin was driving the enemy rapidly through the woods when the Eighth and Eleventh Texas charged past its left flank upon the led horses. Major Torrey promptly returned with a portion of his command, and some desperate hand-to-hand fighting took place for the possession of the horses. The Second and Fourth Indiana arrived at this time, and four companies of the former and two of the latter charged the enemy's cavalry and drove it three-quarters of a mile, while the remainder of those regiments dismounted and formed on the left of the First Wisconsin, in which order our line again advanced and drove the enemy through the woods, while the Seventh Kentucky made a gallant but unsuccessful attempt to regain the original post of the picket on our right. At this time three bodies of the enemy's infantry advanced on our line across an open field in column of sections, and, disregarding our fire, which fell steadily upon them moved within 30 yards of our front, passing heedlessly over the bodies of their fallen comrades, planted their battle-flag, and began to deploy. Without waiting so hopeless a contest as must have taken place between dismounted cavalrymen and a superior force of trained infantry, our line was withdrawn in good order to its original position, where breast-works of rails were hastily erected, while the mounted men were properly posted for supports with the expectation that the enemy would advance and renew the contest. The First Brigade now arrived and promptly took position on our left. We remained in line within short range of the enemy until 11 p.m., when an order was received to move to Strawberry Plains. The Second Brigade was the last to leave the ground. Owing to my desire to possess the hill, which was considered of the highest importance as commanding the position occupied by the camp of the Federal troops, our men were more freely exposed than they would otherwise have been.
Our loss was 48 killed, wounded, and missing (vide report).(*) We captured 19 of the enemy, and owing to his manner of moving infantry across an open field exposed to our fire, his loss in killed and wounded must greatly have exceeded ours. Deserters last night reported 150. His cavalry was driven out of sight in 15 minutes after the beginning of the action.
This skirmish has increased my confidence in the fighting qualities of the Second Brigade and diminished my own conceit. I pay no undeserved compliments in saying that the charge of Lieutenant-Colonel [Major] Lesslie of the Fourth and Captain Edwards of the Second could not have been bettered; that Major Purdy of the Fourth handled his dismounted men splendidly, and that Major Torrey, by the masterly manner in which he extricated himself from the dangerous position in which my culpable haste had placed him, gained new honors for himself and regiment. Lieutenant Moulton, acting assistant adjutant-general, Second Brigade, who had his horse killed under him, and Captain Robinson, acting assistant inspector-general, who was constantly in the thickest of the fight, deserve special mention for their gallantry. Brigade Surgeon Carrick was very prompt and efficient in attending our wounded. Capt. W. W. La Grange, First Wisconsin, fell with a dangerous (probably mortal) wound while gallantly charging at the head of his company near the crest of the hill.
Very respectfully,
O. H. LA GRANGE,
Colonel, Commanding.
