A pre-Civil War lawyer and United States Marshall in the Wisconsin Territory, he was a Captain in the 1st Regiment of Pennsylvania Militia (known as the "Gray Reserves") when the conflict began. He was tabbed to served on the staff of Brigadier General Francis E. During the end of the September 1862 Antietam Campaign his regiment was engaged unsupported at Shepardstown, (West) Virginia against a sizable Confederate force.Colonel Prevost, in an attempt to stabilize his wavering line in the face of heavy fire, grabbed the regiment's colors and placed himself at the front line. Moments after doing so he was shot in the shoulder and severely wounded by a shell fragment. Carried from the field, his men would go on to sustain almost 300 casualties. Out of action for the rest of the year, he would come back to command his regiment prior to the May 1863 Battle of Chancellorsville before being fully recovered. In that battle his led his men while his arm was strapped to his side, and after the conflict was over it was apparent he could no longer effectively serve in the field.
