John T. Humphreys commanded a company in the Arkansas State Trooops (Co. E, 4th Regiment Arkansas State Troops) July to September 1861. After the State Troops disbanded, he was elected second lieutenant of the 1st Arkansas Light Artillery (Provence/Humphreys/Rivers) at Fort Smith on September 14, 1861. This battery was the PACS successor to Jack Reid's "Fort Smith Artillery" of the Arkansas State Troops. Humphreys was promoted to first lieutenant on April 10, 1862; to captain on July 13, 1862; and resigned on October 15, 1863. I had lost sight of him after that, until I saw your discussion regarding his subsequent command of Roswell's Battery. Many thanks.
