A must-read for those interested in the battle of Gettysburg, the bloodiest battle of the bloodiest war in American history Long recognized as one of the best introductions to the campaign, Albert A. Nofi's The Gettysburg Campaign does not focus exclusively on the three days of the battle, but shows how events of May and June of 1863 set the stage for the engagement, and traces Lee's retreat from the field and the hesitant Northern pursuit, a fascinating tale in itself.
