Primary Data Sources (Books):
Conway's Pre (blue) and Dreadnought (green), as both types fought in WWI (see below):
Jane's, although it could be argued that it is a mixture of fact and fiction it certainly gives the flavour of the era (see below):
Brown who describes in great detail the RN's ship building programme (see below):
Source of "Ship counters/models and maps" to cover all nations and theatres in WWI:
Avalanche Press, Great War at Sea Series:
Russo-Japanese War 1904-05 (see above), I also have these ships in 1/3000 courtesy of Navwar Tsushima Pack and extending out to cover the pre-Tsushima "Yellow Sea" and the like battles around Port Arthur
Board Game Vol. I - The Mediterranean (see above), I had been after this one for a while (seeing it for £60 at Salute in London years ago when I was in London I didn't mind buying it for £25 and waiting while it came from America). Likewise, I have the combatant nations ships (down to and including a representative few destroyers) in Navwar's 1/3000.
Board Game Vol. II - The North Sea, where the big boys play. Jutland and everything else that went on in the North Sea including the American Sixth Battle Squadron of the British Grand Fleet. Yes I have the Navwar 1/3000 models (gaining a flying start with the Jutland Battle Pack and expanding afterwards) for this (down to the representative destroyer level), including the Americans, Baltic Russians and Swedish Fleets.
The remaining Avalanche Press WWI naval game of interest is the Cruiser Warfare (more "commerce raider" global strategy than "Fleet Action"). This would cover Von Spee's East Asiatic Squadron (which did have small squadron actions at Coronel and The Falklands), SMS Emden, SMS Karlschruhe and the SMS Konigsberg.
The Navwar lists have now by and large have been 'plundered' regarding WWI 'standard fair' and I seem to be now extracting the more and more exotic or "ships that never made it off the drawing board"
What is needed is to put all the above to some good use in a "Naval Wargame Campaign"
