Rebellion Record: a Diary of American Events: Documents and Narratives, Volume 3.

early on the evening of the 23d instant, a company of fifty picked men, under command of Lieutenant Grayson, of the Indiana Sixth, left camp for the purpose of reconnoitring in the vicinity of Hodgesville, where it was reported a party of rebels had made repeated visits, committing depredations on the Union citizens of that place. Arriving at Hodgesville he learned from a Mr. Henderson that the rebels were encamped on a hill near a small place called Mud Run, some nine or ten miles further down the road. The whole party immediately set out for that place. After a fatiguing march of over three hours duration, through a drenching rain, and just as the gallant little band of Hoosiers were rounding a turn in the road, they suddenly came upon a party of rebels about one hundred and fifty strong, who immediately fired upon our boys that were in the advance, which consisted of Lieutenant Grayson, Sergeant J. W. Taylor, Corporal W. H. McCann, Private Newton, and Orderly Sergeant T. J. Dunlap, who were some two hundred yards in advance of the little band. At the first fire Sergeant Taylor fell, Lieutenant Grayson received a slight wound in the arm, and Sergeant Dunlap received a slight wound in the left arm. The rebels now made a desperate charge upon the gallant lieutenant and his brave comrades, but they were met by the brave sons of Indiana just in time to save their gallant leader and his party. Our boys came up with a tremendous yell, which led the enemy to believe it was the advance of a larger force. Lieutenant Grayson, although wounded and bleeding profusely, gave the command, “At 'em, boys! Give them the steel, boys!” &c., &c. The brave Indianians made a desperate charge, which caused the enemy to retreat in great disorder, leaving three dead and five wounded. The rebels continued their flight for several miles. Our boys continued in hot pursuit, capturing a large number of horses, wagons, &c., and about five hundred pounds of powder. Our boys, worn out and fatigued, gave up the chase, well satisfied with their light's work. After burying the dead and leaving the wounded well cared for by the citizens near the scene of action, they returned to camp with their captured property. The wounded are all doing well. Sergeant Taylor, who fell at the beginning of the action, was shot in the right leg, just above the knee. His wound, although very bad, fortunately is not fatal; he will be able to be out in a short time. Lieutenant Grayson's wound was but slight; he is on duty at this time. Sergeant Dunlap is on duty again. There were several of the Indiana boys slightly wounded, but none fatally.

Perhaps you have heard of this affair before this by telegraph, but knowing more about it than any one else, I send you the full particulars, as near as I can recollect. The boys are anxious to meet General Buckner and the rest of his cowardly rebels.
