In Death Ground: Wargames Rules for the Pre-Gunpowder Era, c. 2500 BC to 1300 AD

From the Introduction:

In Death Ground is a set of rules for gaming medium to large scale battles sent in the pre-gunpowder era, or roughly between 2500 BC and 1300 AD…

A great deal in these rules will be familiar to those who have played Ruga-Ruga Publications' previous sets, "Death In the Dark Continent" and "Too Few to Fight, Too Many to Die". We believe that the basic mechanisms produce a game which is simple enough to be enjoyable - and to be played to a finish in a leisurely evening - while retaining as much tactical interest and period flavor as possible.
