GDG- Pipe Creek where are the maps?

[Tom Ryan]

To continue on the map theme, after Jackson's death, Hotchkiss' assignment
was with Ewell's corps.  My recollection is that, while Ewell was the
advance of the invasion, Hotchkiss worked on individual maps for operational
purposes as the corps progressed northward.  I gather what this meant was
that the original map provided the "big picture," while the operational maps
were for the  use of divisions, brigades and regiments operating in specific
local areas.
