Answer 2

The commanders of the 9th and 10th US Cavalry Regiments faced a skilled adversary who used unconventional tactics and methods as well as an international border to seek sanctuary. The Apache chief Victorio was the principal threat to Western settlements during the post Civil War period. He led a large band of warriors across the deserts and mountains of southern New Mexico and Texas, spreading terror and destruction as he struck at will. Only after an intuitive regimental commander’s shift in tactics did the Army finally gain the upper hand and drive this rogue Apache into Mexico where Mexican forces under Colonel Joaquin Terrazas in the Battle of Tres Castillos ultimately trapped and killed him on a remote mountain.
