Statement of Significance (as of designation - July 4, 1961):
This was the most southwesterly military outpost in the United States, from its establishment in 1822 until the Mexican War. In March 1845, Texas was offered admission to the Union and Gen. Zachary Taylor's "Army of Observation", stationed at Fort Jesup, was ordered to hold its troops ready to march into Texas. After Texas joined the Union, Taylor was ordered to move into the new State. The site is now Fort Jesup State Monument.
