October 27, 1862, Col. J. H. Mix received authority from the War Department to raise, with the consent of the State government, a regiment of cavalry in this State. The organization of the regiment was, however, not completed, and but two companies were recruited. These were mustered in the service of the United States for three years between January and May, 1863, and were recruited principally: A at Lancaster, Tonawanda, Aurora, LeRoy, Golden, Pavilion, Bethany, Newstead and Cheektowaga; and B at New York city.

These companies left the State in May, 1863; served in the Department of North Carolina (18th Corps), mostly attached to the I2th N. Y. Volunteer Cavalry, and were mustered out and honorably discharged, July 22, 1865, at Raleigh, N. C.

They lost in the service by death, of disease and other causes, fourteen enlisted men; of whom five enlisted men died in the hands of the enemy.
