Gettysburg's Forgotten Cavalry Actions examines in detail three of the campaign's central cavalry episodes. The first is the heroic but doomed legendary charge of Brig. Gen. Elon J. Farnsworth's cavalry brigade against Confederate infantry and artillery. The attack was launched on July 3 after the repulse of Pickett's Charge, and the high cost included the life of General Farnsworth. The second examines Brig. Gen. Wesley Merritt's tenacious fight on South Cavalry Field, including a fresh look at the opportunity to roll up the Army of Northern Virginia's flank on the afternoon of July 3. Finally, Wittenberg studies the short but especially brutal July 3 cavalry fight at Fairfield, Pennsylvania. The strategic Confederate victory kept the Hagerstown Road open for Lee's retreat back to Virginia, nearly destroyed the 6th U.S. Cavalry, and resulted in the award of two Medals of Honor.
