Cavalry in the American Civil War played a crucial role in reconnaissance, raiding, and flanking maneuvers. Unlike infantry, cavalry units were mounted on horses, allowing them to move quickly across the battlefield. They were often used to gather intelligence about enemy positions and to disrupt supply lines, making them essential for both the Union and Confederate armies. The effectiveness of cavalry varied throughout the war, with notable leaders like Philip Sheridan for the Union and J.E.B. Stuart for the Confederacy. While cavalry charges were less common than in previous conflicts, their mobility and speed remained vital for strategic operations and communication between units.
