A map detailing the Continental Army’s encampment at Valley Forge during the winter of 1777 to 1778.

This map was drawn by Antoine-Jean-Louis Le Bègue de Presle Duportail (1743-1802) and is labeled in French. Duportail served as tactical advisor to George Washington and later as the French Minister of War. The title on the map reads “Brouillon et Plan du Camp de Vallee Forge-Ordre de Battuelle du Premier ligne,” which when translated reads “Draft and Plan of the Camp of Valley Forge-Order of Battalion of the First line.”
