The Battle of Gettysburg, fought from July 1 to July 3, 1863, was a pivotal clash in the American Civil War. It is considered one of the war's turning points as the Union Army, led by General George G. Meade, successfully defended against the Confederate Army under General Robert E. Lee. The battle marked the furthest advance of Lee's forces into Northern territory and resulted in significant casualties, with approximately 51,000 soldiers killed, wounded, or missing. The Union victory not only boosted Northern morale but also shifted the momentum of the war, leading to an eventual victory for the Union and the abolition of slavery.
