Lanny, It has been awhile since I did any serious study of this but Gano returned to Texas in 1863. Per the ORs, he was transfered to the District of the Indian Territory under Gen Wm Steele and given command of what was Bankhead's Brigade which was located at Camp Hardeman in the Choctaw Nation a few miles south-southwest of Ft Smith AR (I believe on Sugar Loaf Creek -- Cooper's camp was named "Camp Sugar Loaf). Gano arrived there on Nov. 1st "with a company of men" presumed to his Grapevine Guards. His brigade was ordered back to the Red River to be supplied/clothed for the winter.
