Topographical Engineers were authorized for War Department duty by an act of 3 March 1813, to conduct engineering surveys for military purposes and to explore routes for the passage of troops. Specifically the duties of the topographical engineers were "to make such surveys and exhibit such delineations as the commanding generals shall direct; to make plans of all military positions which the army may occupy and of their respective vicinities, indicating the various roads, rivers, creeks, ravines, hills, woods, and villages to be found therein; to accompany all reconnoitering parties sent out to obtain intelligence of the movements of the enemy or of his positions; to make sketches of their routes, accompanied by written notices of everything worthy of observation therein; to keep a journal of every day's movement when the army is in march, noticing the variety of ground, of buildings, of culture, and distances, and state of roads between common points throughout the march of the day; and lastly, to exhibit the positions of contending armies on the fields of battle, and the dispositions made, either for attack or defense."
