Which events were the north successful in?

The North was successful in several key events during the Civil War, including the Battle of Gettysburg in 1863, which marked a significant turning point by halting the Confederate invasion of the North. Additionally, the Siege of Vicksburg, which culminated in July 1863, gave the Union control of the Mississippi River, splitting the Confederacy. The capture of Atlanta in 1864 further boosted Northern morale and contributed to Abraham Lincoln's reelection.
