The Battle of Gettysburg took place during the American Civil War from July 1 to July 3, 1863. It was a significant turning point in the war, marking the furthest advance of Confederate General Robert E. Lee’s Army of Northern Virginia into Northern territory. The battle ended with a Union victory, resulting in heavy casualties on both sides—approximately 51,000 soldiers were killed, wounded, or missing. The Union’s success bolstered morale and turned the tide of the war in favor of the North, ultimately leading to its victory in 1865.
