My latest release from LFG is a supplement for "Broadside and Ram" entitled "The Schleswig Holstein Question".
This supplement allows players of “Broadside and Ram” to extend their games to the Second Schleswig War, fought between Denmark and the allied Prussia and Austria in 1864, and also the Franco Prussian war of 1870 (although here the naval warfare element is conjectural). Summaries of the naval aspects of both conflicts is followed by ship data for all the major and minor warships involved.
Additional data is provided for a selection of British, Dutch, Norwegian and Swedish ships of the era that could have been “on scene” and may form the basis for a hypothetical game. Finally a short set of additional rules covering sailing ships is included.
A copy of "Broadside and Ram" is required to use this supplement, which is available from Wargame Vault for $2.50
