Based on extensive historical research, Clash of Giants provides the naval wargamer with everything they need to fight the battle of Jutland, either as a battle or as a mini-campaign. Clash of Giants has been written for use with LFG's "Si Vis Pacem" WW1 naval rules, but is adaptable for use with any set of naval rules covering the period. As well as the main campaign book the set includes three separate annexes containing charts, order sheets and ship data. —description from the publisher
