* In the summer of 1863, Confederate forces under General Robert E. Lee invaded the North. They were met in the first days of July by Union forces under Major General George G. Meade at a little town in southern Pennsylvania named Gettysburg, resulting in three days of extraordinarily violent fighting in one of the most decisive battles of the American Civil War. This document tells the story of the Battle of Gettysburg. A list of image credits is provided at the end of this document.
