Dand C is supported by two theatre-specific booklets.
"By River and By Sea" covers the American Civil War in more detail, with two campaign systems and comprehensive ship data for over 175 ships and classes of the Union and Confederate navies.
"War of the Pacific" is something I've been working up to for decades and comprises a campaign system, ship data and brief campaign history covering the War of the Pacific, 1879-1883 between Chile, Peru and Bolivia, and also with my “Iron and Fire” more detailed rules from A&AGE. Ship data for the complete Peruvian and Chilean fleets is provided. Having visited Chile in 1994 and stood on the decks of the Peruvian / Chilean ironclad Huascar this is the culmination of over 20 years planning, and something I'm rather pleased and proud of :)
The third element of this project is the Paraguayan War, or the War of the triple Alliance, which again will feature a campaign system and comprehensive fleet data. This is all set to tie in with the excellent range of 1/1200 models from Spithead.
All three are available from Wargame Vault for a fiver. Links below if anyone is interested.
