Organized November 24, 1863, under Colonel Robert W. Ratliff, it moved into Kentucky. In May, 1864, it joined General Burbridge's raid on Saltville and afterwards returned in pursuit of John Morgan, and engaged him successfully at Mt. Sterling and Cynthiana. In September it made another raid upon Saltville, and again in November passed Cumberland Gap under Generals Burbridge and Stoneman, driving the Rebels before them. The salt works, foundries and immense stores were destroyed. In the spring of 1865 it joined Stoneman's celebrated raid into Virginia and North Carolina, releasing Union prisoners at Salisbury and cutting the railroads in all directions. After Lee's surrender it aided in the capture of Jeff Davis, and moving through South Carolina, Georgia and Alabama, captured Generals Bragg and Wheeler with their escorts. It finally rendezvoused at Nashville and was mustered out November 14, 1865.
