The game and design was fully described in Miniature Wargames with Battlegames, issue 365 (September 2013), so I suggest you order a backcopy to find out all the details.
Here are some documents:
- Flyer (Dutch), that was handed out to the participants.
- Game cards. For the frequency of the cards needed to compose a playing deck, please refer to the article mentioned above.
SOme photos, focusing more on the river itself (where the game was being played), from a replay of the game during the Red Barons convention in Gent, 2013.
