On 29 July 1857, the Regiment caught up with the Cheyenne on the bank of the Solomon River. As the two groups paused within about a mile of each other, the cavalry commander, Col. E.V. Sumner, gave the command "Gallop march." Both groups approached each other at full speed. Col. Sumner then commanded "Sling carbines! Draw Sabers! Charge." It was the first time sabres had been used in the West. The astonished Indians, whose medicine, administered by holy men before the battle, protected them from carbines but not from sabers, became terrified when they saw the sabers. They pivoted and ran as fast as their horses would carry them away from the troopers. The chase lasted for about seven miles before the Indians, having faster horses, pulled ahead too far for the cavalry to follow. During the brief fighting that took place during the chase, two troopers were killed and nine, including Lieutenant J.E.B. Stuart (the future Confederates' most famous cavalry general during the Civil War), were wounded. An estimated nine Indians were killed on the field and an unknown number were wounded. The cavalry wounded and a detachment of infantry were left behind in a makeshift fort while the rest of the 1st Cavalry followed the Indians as best they could.
