Before, and between, the World’s defining conflicts, mapmakers were busy documenting the locales that would become the seats of war. In our map collection you will find historic maps, hundreds of our one-of-a kind troop movement maps, and numerous animated maps, in which the movements of battle come to life.

This list of battle maps show campaigns of major military conflicts including troop movements, defensive structures and groundworks, roads to and from sites of military engagements, campsites, and local buildings, topography and vegetation.

Some of the maps are manuscripts drawn on the field of battle, while others are engraved including some that have manuscript annotations reflecting the history of the battle or campaign.

A significant number of battle maps provide information about the locality that is not available elsewhere such as the location of plantations, the names of landowners in the area, the configuration of small towns and villages, and indications of prior settlement by native Americans.
