This book introduces the fascinating subject of ancient wargaming using the latest edition of DBA version 3.0. De Bellis Antiquitatis have become known for the combination of simple game mechanics and playability. The rules are easy to learn, but the finer details of tactics are hard to master. The rules are extensively used for competitions around the world. The book starts by discussing how to choose a period of history and build an wargaming army, then it includes the complete DBA 3.0 rules with a detailed step by step play through of a sample game- Germans v Romans on the bank of the river Rhine. There are also numerous sample army lists with discussion of the sources on which they are based. Sue Laflin-Barker was a key contributor to the development and success of WRG. This is her first solo authorship of a wargaming book.
