San Marcos br/Hays County, Texas br/29 53.573' N 97 55.849' Wbr/br/Text: The Republic of Texas Congress in Dec. 1838 called for military roads and forts from Red River to the Nueces. A road from Austin, joining El Camino Real near St. Mark's Springs, was designed for rapid communication between San Antonio and the Capital. Post San Marcos was to be constructed at the springs to safeguard travel. Adj. Gen. Hugh McLeod (1814-62) laid out the fort, to be garrisoned by a company of 56 men. Capt. Joseph Wiehl's Co. H, 1st Inf. Regt., in Oct. 1840 completed the road and the fort. In 1841 the Republic of Texas army disbanded for lack of funding, and the post was closed.
