This was organized somewhat peculiarly. Under the gloom induced by BUELL's retreat, in the summer of 1862, and the movement into Kentucky of Kirby SMITH and HEATH, Governor TOD, August 25th, ordered the Seventh cavalry, or "River Regiment," to be recruited - one hundred men in each of the counties of Meigs, Washington, Athens, Gallia, Scioto, Adams, Clermont, and Brown, and three hundred in Hamilton county. Within six days sixteen hundred men were enrolled. It rendezvoused at Ripley, and when the enemy's cavalry appeared at Augusta, Kentucky, a few miles below, company E, of the Seventh, procuring some muskets and other small arms, crossed and drove them out, with considerable loss to the invaders, but none to the bold assailants. After BRAGG's retreat began, four companies were sent on a scout from Maysville into eastern Kentucky, and, west to Falmouth. November 22d, the First battalion was sent to the field, and joined General GRANGER's force at Lexington, whence companies A, B, C, and D matched for the first raid into east Tennessee, upon which a rebel regiment guarding a long railway bridge at ZOLLICOFFER's Station was captured without firing a gun, and another force, six miles distant, was taken after a spirited though brief action. Two fine railroad bridges were burned, and much other property destroyed. December 20th the Second battalion entered the field, with General GRANGER, as also, eleven days later, the Third. February 22, 1863, the entire regiment marched to Richmond, Kentucky, to repel a reported invasion. The latter part of March it joined in a vigorous pursuit of PEGRAM's cavalry, and engaged it heavily at Dutton hill, on the thirty-first, when a sabre charge by five companies of the Seventh decided the day. May 1st it was in another attack upon PEGRAM, at Monticello, and helped to rout him handsomely. June 9th, at the same place, it again, with other cavalry, attacked and drove out the same pestilent invader. Upon its retirement it was in turn attacked by PEGRAM, and fought successfully the desperate action at Rocky Gap, for which General BURNSIDE complimented the regiment in orders. June 10th one hundred picked men of the command joined another expedition to destroy the east Tennessee railroads, where immense mischief was done the rebels. In July it engaged in the pursuit of Morgan across Ohio, traversing Hamilton county in its march, via Harrison, Springdale, Glendale, and Miamiville; and ,was the first to attack the bold raider in his last stand at Buffington. Colonels Basil DUKE and SMITH, with their staffs and an escort, surrendered to Colonel GARRARD, of the Seventh. September 3d the regiment entered Knoxville, and assisted in the capture of Cumberland Gap, with its garrison, on the ninth. It marched thence to Carter's Station, and defeated a large force there. It then held a strong post in the mountains east of Knoxville till October 10th, when it took part in the battle of Blue Springs, losing Captain HYLEY, of company K, while heading a charge. One of the forts at Knoxville was subsequently named from him. At Bristol, on the Tennessee and Virginia line, an immense amount of supplies and railway property was destroyed by it. At Rogersville, November 6th, it, with a Tennessee regiment and a battery, was fiercely attacked and overpowered by nearly four times the number of the Union force, losing one hundred and twelve men and some of its best officers. Colonel GARRARD was in command, and a court of inquiry not only exonerated him from blame, but praised his conduct in the affair. During the siege of Knoxville, the Seventh defended Cumberland Gap, and December 5th joined in pursuit of the retreating enemy, having seven days and nights of almost incessent skirmishing and close fighting. On the twenty-third it drove a force from New Market, and on Christmas, after a long day's hard fight, cut its way out of a largely superior force at Dandridge. For some time in January, 1864, it picketed the fords of the French Broad above that place. On the twenty-seventh it aided in the defeat of two divisions of WHEELER's cavalry at Fair Garden. In May the regiment reached central Kentucky, by rail for east Tennessee, to repel MORGAN, and on the twelfth participated in the successful attack upon him at Cynthiana. The Seventh alone captured about five hundred prisoners in this fight, but lost some valuable officers and men. Colonel GARRARD's brigade, including the Seventh, pursued MORGAN vigorously to the mountains of eastern Kentucky. July 4^th the regiment started for Atlanta, arriving on the twenty-sixth, and taking active part in the operations that led to the fall of the "Gate City." It encamped at Decatur till October 4th, and then engaged for a month in scouting and forageing for the Atlanta garrison. It was in the pursuit of HOOD, and held the left of the Union line tenaciously at the battle of Franklin November .30th. It participated in the battle of Nashville and the subsequent pursuit; spent the winter at Gravelly Springs; aided to destroy rebel railways and iron works the next spring; engaged and defeated FORREST at Plantersville April 1st; and after LEE's surrender scouted northern Georgia to intercept Jefferson DAVIS. After his capture the Seventh was ordered to Nashville, where it was mustered out on Independence day, 1865. It had numbered, including recruits, one thousand four hundred members, of whom
