Gettysburg Maps
The Pentagoet History of the Gettysburg Campaign includes some three hundred detailed static maps, and over thirty equally detailed animated maps of key events of the campaign and the battle. These maps have been generated from USGS 2D and 3D maps of the areas in question and adapted to reflect contemporary accounts and descriptions (e.g., Batchelder and the U.S. Official History).

Gettysburg - LEE's Plan
AM 2 July 1863

Confederate General LEE's appreciation of the Federal position facing him early on 2 July was deeply flawed, for lack of cavalry. Based on his misapprehension of the Federal line, he proposed a shallow flanking attack against what he believed to be the exposed left wing of the Union forces present along the Emmitsburg Road. In actuality, the Federal positon was further East, along Cemetery Ridge.
