Gamble for Victory: Battle of Gettysburg

In July 1863, after having observed a forward column of Union General George G. Meade's cavalry, General Robert E. Lee sent his 75,000 men of the Army of Northern Virginia to meet the 97,000 strong Union Army of the Potomac.
Of more than 2,000 land engagements of the American Civil War, Gettysburg ranks as one of the most horrific and devastating battles; more men actually fought and died on this battlefield than in any other encounter on North American soil and the battle itself marked the beginning of the end for the Confederacy.
