21st Kentucky Infantry (Union)-- Part 1: "The Old Infantry"

From Wikipedia.

The 21st was organized at Camp Hobson, near Greensburg, Kentucky, and Camp Ward, Kentucky, and mustered in for a three-year enlistment on December 31, 1861, and January 2, 1862, at Green River Bridge, Kentucky, under the command of Colonel Ethelbery Ludlow Dudley.

Before the war, most of the regiment's men were members of "The Old Infantry," a state guard unit commanded by Captain Samuel Woodson Price, who would later command the regiment.

The regiment mustered out of service December 9, 1865.

All of its duty was in the Western Theater.
