As we anticipated, an early "_reveille of musketry_" awoke the party, and mounting my sorrel Rosenante, I proceeded to investigate "why we do these things," or to learn what the _quarrel is all about_. Crossing the river, I caught up with Major Tracy just as he was returning from his expedition to General Starnes's house. It was about eight o'clock as we came in sight of College Grove, a little village about a mile beyond Harpeth River. Here we turned toward Triune, and had left College Grove half a mile to the rear, when we heard the rebels firing upon a few stragglers of the Tennessee Cavalry. Major Tracy promptly countermarched his battalion, which was in the rear, and double-quicked back to the school-house at the town, and within a hundred yards of the rebel cavalry, who were drawn up in a line, in the front and rear of some houses, on the right of the road. The Major, seeing they outnumbered him two to one, halted, and sent word back to Major Burkhardt to reinforce. He then formed a line of battle across the road, awaiting the other battalion. Just as it arrived, Major Tracy thought he saw signs of wavering in the rebel line, and immediately ordered Squadron E to "Forward, by platoons! Double-quick! Charge!" and galloping to the front, along with Lieutenant Thurman, away they go. The rebels waver, break, and now comes the chase. The Major gains upon their rear, and brings rebel No. 1 to the dust, by the aid of a Smith & Wesson revolver. The Major, now wild with excitement, threw his cap in the air, and, hallooing for the boys to follow, continued the chase. The race was fully a three-mile heat, in which we captured fifty-nine rebels. Thirteen were _wounded by the saber_, four very severely. There were not more than fifteen or twenty of our men close on their rear at one time, and as the rebels turned out on the road-side to surrender, the Tennessee boys never stopped to make sure of them, but yelled to them to drop their guns and dismount, and if they stirred before they returned, they would murder them. After going as far as the few thought it safe, they returned to camp, bringing the prisoners, horses, and various implements of warfare, "sich" as fine English shotguns and the like. This was certainly one of the most gallant affairs of the season, and may be considered among the most successful charges of the war; for, while not a man of ours was injured, fifty-nine rebels were taken, and I saw more saber cuts that day than any time since I have been with the army.
