Union General Philip Sheridan's cavalry clashed with Confederate horsemen under Wade Hampton near Trevilian Station, Virginia, in the war's largest cavalry engagement. Two days of brutal, close-range fighting cost roughly 1,600 Union and 800 Confederate casualties. Sheridan failed to destroy the rail line as intended, but the battle underscored the increasingly decisive role of mounted troops fighting dismounted, rifle in hand.
By June 1864 cavalry warfare had changed. Gone were the romantic sabre charges of earlier campaigns; increasingly, horsemen dismounted and fought from behind fence rails and trees with repeating carbines, functioning as a fast-moving infantry. Trevilian Station displayed this transformation at its bloodiest.
Sheridan had ridden out from Grant's army with two divisions to sever the Virginia Central Railroad and link up with Union forces near Charlottesville. Wade Hampton, anticipating the move, positioned his own cavalry to block him. The two forces collided head-on, and George Custer, leading a Union brigade, found his men briefly surrounded and cut off, forced to fight in a full circle while defending a captured wagon train.
The fighting on June 11 and 12 seesawed violently, with charges and countercharges across broken, wooded terrain that negated normal cavalry tactics. Sheridan ultimately withdrew without breaking the railroad, a tactical setback, but the battle drained Confederate cavalry resources Lee could not easily replace. It remains, by numbers engaged, the largest cavalry battle of the entire war.
