https://williamitewarfare.blogspot.com/For anyone interested and for the fewer who follow my Williamite Warfare blog please find the above link. I have today repopulated my core rules supplement, Dutch army list, French army list, a Dutch basing convention guide and a Dutch OOB for Seneffe. All documents are now PDF accessible and downloadable. The rules are an extension supplement for WAB English Civil, War rules.
This has been a relatively inactive blog and very much a niche subject but I have not abandoned it. I am currently developing the Seneffe township for my concept of the game.
I have since the time of drafting these rules become a convert to Black Powder and will most likely develop an alternate Williamite Warfare model in the future.
Anyway, if anyone finds this useful or even plays with it - please report back.
