This is a history of General Robert E. Lee's Campaign into Pennsylvania that ended in defeat at the Battle of Gettysburg in early July of 1863.

This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Because it was the greatest, Gettysburg is also one of the most analyzed battles of the Civil War. This volume, first published in 1887 and long out of print, is still among the most authoritative works on the subject.
