<em>Anglo Texans greeted the end of the U.S-Mexican War in 1848 with the hope that federal troops would at last put an end to violent encounters with Indians and Mexicans along the state's western and southern borders and open the vast frontier to settlement. All too quickly the lure of nearly free and unbroken land attracted a multitude of pioneers. So rapidly, in fact, that it thrust some white settlers far beyond the protection of the eight new military installations established at war's end, running from Fort Worth in North Texas to Fort Duncan on the Rio Grande.</em>
<em>In response, the U.S. Army in 1851 began establishing a new line of forts a hundred miles beyond the original vanguard. Others were located in the Big Bend country along the Rio Grande and in extreme South Texas.</em>
