The Battle of Gettysburg was the largest battle fought in North America and a major turning point in the American Civil War. Union forces under George G. Meade halted Robert E. Lee's invasion of the North after three days of fierce combat.
Gettysburg mattered because it ended Lee's most ambitious northern campaign and inflicted losses the Confederacy struggled to replace. Its symbolic power in American memory was later deepened by Lincoln's Gettysburg Address.
