The Battle of Gettysburg, fought from July 1 to 3, 1863, is often considered the turning point of the American Civil War. This battle was significant for several reasons: it marked the end of Confederate General Robert E. Lee's invasion of the North and resulted in a substantial Union victory. The defeat weakened the Confederate Army both strategically and psychologically, shifting the momentum towards the Union side. Additionally, the heavy casualties suffered by both sides underscored the war's brutality and the need for a decisive resolution. Following Gettysburg, President Abraham Lincoln delivered the Gettysburg Address, emphasizing the ideals of liberty and human equality.
