Ad Mare Bellum is a quick playing set of Ancient naval rules covering the period 2000BC to 900AD, allowing small and medium sized games with 30 ships a side or more to be completed in a couple of hours or less. They have been written with 1/1200 models such as those from Navwar and Langton in mind, but could be used with larger or smaller models with appropriate changes in ranges and movement. Bookkeeping is minimal, using simple markers to indicate ship damage and crew casualties. Data for over 30 different broad ship types and nine different fleet lists are included, from the Egyptians and Sea Peoples, through classical Greek and Roman to Norse and Byzantine fleets and ships. —description from the publisher
