He was the commander of Apache Scouts until 1891. That same year, he became a compatriot of the District of Columbia Society of the Sons of the American Revolution and was assigned national membership number 1976.
In 1891, he became First Lieutenant and he was transferred to the 9th Cavalry Regiment. From 1891 to 1892 he was an observer, stationed at Düsseldorf, Germany with a Westphalian Hussar regiment. The discipline of the German Army greatly impressed him.[6]
He was back with the 10th Cavalry by early 1892. From 1892 until his death in 1893, he lived in Fort Custer, Montana. In 1892 he married Elizabeth Clemens of St. Louis, Missouri; they had one son. After diving into shallow water and striking his head, Clarke drowned in the Little Bighorn River on July 21, 1893,[7] and was buried at Calvary Cemetery in St. Louis, Missouri.[5]
