The Library of Congress has a collection of
cartographic items made by Major Jedediah Hotchkiss (1828-1899), a topographic engineer in the Confederate Army. Hotchkiss made detailed battle maps primarily of the Shenandoah Valley, some of which were used by the Generals Robert E. Lee and Thomas J. "Stonewall" Jackson for their combat planning and strategy. Several of the maps have annotations of various military officers, demonstrating their importance in the military campaigns. The collection also includes maps made or used by Hotchkiss during his post-war years, including maps with information about railroads, minerals and mining, geology and history, most of which focus on Virginia and West Virginia, but also cover other states and even the world.
The collection consists of 341 sketchbooks, manuscripts, and annotated printed maps, the originals of which reside in the Library of Congress' Geography and Map Division.
A good many of these are available online
