In 1860, during their first attempt to create the Golden Circle, several thousand Knights assembled in southern Texas to "colonize" the northern Mexico. Due to insufficient resources and organizational shortfalls, however, that filibuster failed. Later, the Knights shifted their focus and began pushing for disunion, spearheading prosecession rallies, and intimidating Unionists in the South. They appointed regional military commanders from the ranks of the South's major political and military figures, including men such as Elkanah Greer of Texas, Paul J. Semmes of Georgia, Robert C. Tyler of Maryland, and Virginius D. Groner of Virginia. Followers also established allies with the South's rabidly prosecession "fire-eaters," which included individuals such as Barnwell Rhett, Louis Wigfall, Henry Wise, and William Yancy.
