Perhaps the two most important battles the Union won during the US Civil War were the Battle of Gettysburg and the Siege of Vicksburg. Both occurred in July of 1863, with Gettysburg damaging Lee's army sufficiently enough that he would never again attempt offensive operation into Union soil. This is important since the thrust of the Gettysburg campaign was to alleviate the burden of war on Virginia, which had been the main battleground in the east since 1861.
The loss of Vicksburg split the far western Confederacy from the east and thereby impeded the flow of supplies such as cattle and reinforcements from the west to the eastern armies. There were many other Union victories, but these two were the most devastating to the hopes of the Confederate nation.
