Oliver Steele
Handbook of Texas Online, Aragorn Storm Miller, "Steele, Oliver,"
On June 11, 1862, he joined Waul's Texas Legion as adjutant at Brenham. During the siege of Vicksburg, Steele received mention for distinguished service from his superiors. He was taken prisoner after the fall of Vicksburg. Following his exchange, Steele returned to Texas where he served as commander of the port of Gonzales and later as lieutenant colonel of the third military sub-district headquartered at Victoria.
