The Battle of Gettysburg is often considered the turning point of the American Civil War. Fought from July 1 to July 3, 1863, this battle marked a significant defeat for Confederate General Robert E. Lee's Army of Northern Virginia. The Union victory at Gettysburg halted Lee's invasion of the North and boosted Northern morale. Additionally, the significant casualties suffered by the Confederate forces weakened their ability to mount extensive offensives afterward. The Gettysburg Address, delivered by President Abraham Lincoln months later, further solidified the battle's importance in reinforcing the commitment to preserving the Union and the principles of liberty and equality.
