What is DBA?
De Bellis Antiquitatis ("The Wars of Antiquity") or DBA is a set of fast-play rules for ancient and medieval wargaming using miniature figures. The rules are authored by Phil and Sue Barker and Richard Bodley Scott and published by the Wargames Research Group. The current edition (DBA 2.2) was released in January 2004.
Fanaticus is an on-line community promoting ancient and medieval wargaming using the De Bellis Antiquitatis (DBA) and the DBx-family of rules. Fanaticus is intended to promote DBA and provide resources for DBA players.
The Unofficial Guide to DBA was written by a group of active players and written with the community of active players in mind. The guidebook explains and sets a common understanding of the rules. It is a free download courtesy of W.A.D.B.A.G. / Washington Area De Bellis Antiquitatis Gamers
