Not to be anual or anything but the battle of vicksburg,civil war, was the biggest and bloodies war there was.
Nope. It was one of the bloodiest battes In US history (it's tiny compared to some of the biggest world battles). Gettysburg is the biggest battle of the civil war in terms of casualties and number of people involved. And the civil war was by no means the bloodiest war in history. Oh and... Battle of borodino was still bigger then Vicksburg OR Gettysburg. Over 100,000 soldiers on each side, face off on one bloody day.
And yes, battle of stalingrad is the biggest battle in history.
