Context paragraphs:
Culture of Texas: The culture of Texas can at face value be described as a melting pot of "Southern" and "Southwestern" features, with pockets of ethnic group town and settlements in many locations.  The large geographic nature of Texas has also played a role in its culture.  An in depth analysis of Texas reveals it is a border region.  Although Texas is placed in the Southern United States by the United States Census Bureau, It is a border between the western prairies, the Deep South, and Mexico, influenced by Hispanic and Anglo traditions.  It is a place of island communities from Germany, Czechoslovakia, Poland, Mexico, Africa, southern Anglo populations, and historic tribes of Native Americans.  Its culture is a complex blending and separation of the cultures different people originally brought with them to Texas.  Its African American community contributed to the blues through various artists, and it is the only place in world where its past musicians such as Adolph Hofner sang Western Swing Style music in Czech and German.  All of East Texas and the Gulf Coastal Plains regions near the Louisiana border have a Cajun/Creole influence.  Southwestern Louisiana Creole language is mostly spoken in Southeastern Texas (Houston, Beaumont, Port Arthur, and Orange).

Ojo de Agua Raid: The Ojo de Agua Raid was the last important military engagement between Mexican Seditionistas and the United States Army.  It took place at Ojo de Agua, Texas.  As part of the Plan of San Diego, the rebels launched a raid across the Rio Grande into Texas on October 21, 1915 aimed at harassing the American outposts along the Mexican border and disrupting the local economy.  After moving across the border, the Seditionistas began an assault against the United States Army Signal Corps station at Ojo de Agua.  The small group of American defenders was cornered into a single building and suffered heavy casualties before reinforcements arrived driving the Seditionist force back into Mexico.  The raid proved to be the tipping point in the American conflict with the Seditionistas, as its severity convinced American officials to send large numbers of American troops to the area in order to deter any further serious border raids by the Mexican force.

Border War (1910–19): The Border War, or the Border Campaign, refers to the military engagements which took place in the Mexico-United States border region of North America during the Mexican Revolution.  The Bandit War in Texas was part of the Border War.  From the beginning of the Mexican Revolution in 1910, the United States Army was stationed in force along the border and on several occasions fought with Mexican rebels or federals.  The height of the conflict came in 1916 when revolutionary Pancho Villa attacked the American border town of Columbus, New Mexico.  In response, the United States Army, under the direction of General John J. Pershing, launched an expedition into northern Mexico, to find and capture Villa.  Though the operation was successful in finding and engaging the Villista rebels, and in killing Villa's two top lieutenants, the revolutionary himself escaped and the American army returned to the United States in January 1917.  Conflict at the border continued however and the United States launched several more smaller operations into Mexican territory until after the American victory in the Battle of Ambos Nogales, leading to the establishment of a permanent border wall.  Conflict was not only subject to Villistas and Americans; "Maderistas", "Carrancistas", "Constitutionalistas" and Germans also engaged in battle with American forces during this period.

Butterfield Overland Mail in Texas: In Texas, the Butterfield Overland Mail service created by Congress on March 3, 1857, operated until March 30, 1861.  The route that was operated extended from San Francisco, California to Los Angeles, then across the Colorado Desert to Fort Yuma, then across New Mexico Territory via, Tucson and Mesilla, New Mexico to Franklin, Texas, midpoint on the route.  The route through Texas followed first the northern route to the Pecos River and downstream to Horse Head Crossing.  The route in West Texas was changed in 1859, in order to secure a better water supply on the route and to provide mail service to a more settled area, the stages between Franklin and the Pecos River followed the San Antonio-El Paso Road to Camp Stockton and then turned east to Horsehead Crossing.  From Horsehead Crossing the route crossed Texas to the Red River and into Indian Territory.  In 1860 the route was changed to another route from Jacksboro to Sherman via Decatur due to the building of a new toll bridge at Bridgeport, that avoided delays crossing the West Fork of the Trinity River when it was flooded.  From Colberts Ferry the route went on to Fort Smith, then up across Arkansas and southwest Missouri to Tipton with the final leg by train to St. Louis.  The Texas mail route was so long that the route there, like that in California, was divided into two divisions each under a superintendent.
