When Slough discovered the Texans he went ahead and launched an attack against them. Four companies from Colorado were deployed across the trail. Confederates dismounted and formed a line across the canyon, but the terrain caused some companies to intermingle. Colorado's troops were initially successful and held their ground for a half an hour. However, the Confederates had them out numbered enabling them to outflank them.
Slough then was able to reform his men closer to Pigeon's Ranch with four companies from Colorado and an artillery battery on the hill to their left. Slough also had another battery supported by two companies in the center and the other two companies were on the ridge to his right. Scurry launched a three-pronged attack on the Union line. All three lines were stalled by the Union and a Confederate cannon was disabled. The Confederates positioned snipers on what is now called Sharpshooter's Ridge and they began picking off Union artillery and infantrymen. This combined with Scurry's push into the unions center made their position untenable and Slough then ordered a retreat.
