How the war turned
For two years the war swung back and forth, with Confederate commanders like Robert E. Lee winning stunning victories in the East even as the Union tightened its grip in the West. The great turning came in July 1863, when Lee's invasion of the North was shattered at Gettysburg on the same days that Vicksburg fell and gave the Union the Mississippi.
From 1864 the Union pressed its advantage without let-up. Ulysses S. Grant's Overland Campaign, through the Wilderness and Spotsylvania, traded terrible casualties to pin Lee's army, while Sherman drove through the Deep South. The Confederacy, outnumbered and out-produced, was worn down to collapse.

Why these battles matter
The Civil War settled whether the United States would survive as one nation and ended slavery within it. Its battles reshaped warfare, with rifled weapons, railroads, ironclads and trenches foreshadowing the industrial wars to come, and they cost more American lives than any war before or since.
