The Last Full Measure series are brigade scale Print-and-Play games of Civil War battles.
With as few as seven pages of rules, the system implements regiments, ranged artillery fire, command, reorganization and revovery, and cavalry charges.
The games are offered as "Print and Play" and are free of charge. Everything needed is downloadable from this page; though you will need to be able to view PDF's, and print in color.
The maps are offered in a PDF so they may be printed in "Poster" mode, or "tiled" on an ordinary printer, or a full-size JPG is provided for printing on large format printers.
