Custer's orders were to destroy a railroad bridge across the Rivanna River. His only opposition came from Confederate Maj. Gen.J.E.B. Stuart's "Horse Company" and Confederate infantrymen stationed in a camp near the Rivanna River at Carrsbrook. Custer's men raided the camp under fire from Confederate forces commanded by Capt. R. Preston Chew and Captain Marcellus N. Moorman. The Federal troopers looted the camp and set fire to it, after capturing two Confederate soldiers. During the raid, one of the Confederate artillery pieces exploded, and Custer became confused believing that the explosion was actually the reopening of enemy artillery fire. His men fired into each other and then fled from the camp. The Confederate troops regrouped and chased Custer out of Albemarle.
