George L. Griscom (1837-1901) was an adjutant of the 9th Texas Cavalry, one of four regiments composing Ross’s Brigade in the C.S.A. Army. Ross’s Brigade was one of the most famous Texas military units of the Civil War and was also one of the most active. Their actions in the Civil War included raiding the federal supply base at Holly Springs, Mississippi, in December 1862, as well as spending 112 days under fire and participating in eighty-six engagements in the Atlanta campaign of 1864.
