The best example of how the Battle of Gettysburg was a turning point for the Union in the Civil War is that it resulted in a significant defeat for the Confederate Army. Prior to Gettysburg, the Confederate forces had been successful in their campaigns and had even invaded Northern territory. However, the Union Army's victory at Gettysburg forced the Confederate army to retreat back to the South, marking a critical moment in the war where the Union gained momentum and began to turn the tide in their favor. Additionally, the Battle of Gettysburg is often seen as the high watermark of the Confederate Army and their efforts to invade the North, making it a significant turning point in the war's course.
