From the Indiana Authors And Their Books website: Fort Harrison on the banks of the Wabash, 1812-1912:
Major Robert Sturgis. Appointed Ensign of the Second Infantry, September 28, 1812. Promoted to First Lieutenant March 9, 1814, and resigned February 10, 1818. He had served as a volunteer private in Captain Benj. Parks' troop of light dragoons, in the Tippecanoe campaign, and so was a builder of Fort Harrison. From many legends, he was so interesting a character, 'tis a pity more is not known of his history. He never married. He died in Terre Haute about 1828.
He was Treasurer of Vigo County 1823-1824, and Sheriff 1825-1826. Probably Fort Harrison ceased to be a military post about the time Major Sturgis resigned.
From the History of Terre Haute:
Poor Bob was a universal favorite; he would keep people laughing all the time he talked, and he talked about all the time. Ostensibly he was clerk in somebody's store, but his most constant occupation was drinking whisky.
