A recent (as of 2016) set of ancients wargames rules which borrow heavily from DBM and FoG. They originate in France, where they have been played for some years, but are still new in the UK. Find out more about L'Art de la Guerre at the official web site.
I have produced a ADLG ruler which you are welcome to download and use. It's formatted to print 4 rulers on a page, since they're small. Give them to all your friends!
I haven't tried the rules yet, but they look good and I am sure I will play them soon.
