Robert W. Caskey of Iosco enlisted in Company L of Michigan’s Third Cavalry on October 1, 1861. He was a veteran on January 19, 1864 and he mustered out February 12, 1866. Although the cavalry branch of the army was not brought into as many general engagements as the infantry, and consequently suffered less in killed and wounded, yet its service was of an extremely arduous nature. Men were compelled to be almost constantly in the saddle, riding day and night for hundreds, and sometimes for a thousand miles in a single expedition. But the character of this service, being that of almost constant marching and change of station and duty, renders it impractical to follow and trace the movements of cavalry with as much precision and detail as can be done in the case of infantry regiments.

The Third Cavalry contained between eighty and one hundred men from Livingston County. The regiment was raised in the summer and fall of 1861, having its rendezvous at Grand Rapids. They left that place more than a thousand strong, November 18, 1861, and proceeded to St. Louis, Missouri, where it remained in winter quarters at the Benton Barracks. In 1862 it moved south and participated in the operations at New Madrid.
