Upon arriving at the Rellano station, Huerta had Villa make several probing attacks to test the enemies. Although these were easily repulsed by Orozco's men, they revealed their positions and the fact that the eastern hill lacked artillery support. As a result, on the night of the 22nd, Huerta ordered Villa to take the hill, while the federal artillery shelled both rebel positions to hide the troops' movements. As soon as Villa succeeded Huerta moved his artillery to this newly captured position. Since the eastern hill of the canyon was higher than the western, from this spot the federals were able to rain down artillery fire on the Orozcistas. The rebels attempted to retake the hill, but faced with artillery fire were beaten back. Huerta continued to shell the rebels, and at 9:45 the following morning, he ordered a cavalry charge which after a few hours' fighting, dislodged the rebels from their positions.
