In the civil war, what did cavalry do before battles?

Explanation: In the civil war,the role of the cavalry at the beginning of the Civil War was very limited. Horsemen of both armies were initially limited to patrolling and scouting, guarding supply trains and railroads, and providing escorts to generals. They were only used in battle as shock troops, a tactic which dated back to the Romans.
