Sole Rider by Robert Summers - In 1867, when Black Soldiers of the 9th and 10th Cavalry regiments arrived in the southwest Texas frontier, only a few settlers and adventurers had dared to enter the area. The Indians, respecting the tenacity and courage displayed by the Black Soldiers, called them Buffalo Soldiers. The Buffalo was a sacred animal to the Indians, therefore, the Cavalrymen accepted the title with great pride.
