Resistance In The Desert Site
Ian Croxall has created an amazingly comprehensive site on France’s colonial adventures in North Africa (Morocco) at the turn of the century. There are maps, period illustrations, descriptions of actions, overviews of the native tribes, orders of battle and painting guides.
Ian writes:
At the dawn of the 20th century, an influential party of colonialists was obsessed with carving a colonial empire out of the barren wastes of the North African desert for their personal glory in the name of France. This was achieved through political manipulation and subtle subterfuge on the part of a handful of ambitious army officers. This activity led to a series of small unit actions in North Africa culminating in a full-scale invasion of Morocco in 1907. These actions are eminently suitable for colonial skirmishing on the wargames table.
Front Rank Fire Zulu Skirmish Rules
Front Rank … Fire is a set of free wargames rules for the Zulu War of 1879. The game is for skirmish actions in 15mm to 25mm figures, and you’ll need a ratio of about 3-1 Zulus over Brits to make it a game.
Warhammer Colonials!
These aren’t exactly free wargames rules, but if you already own a set of Warhammer 40K, this is worth checking out. Jervis Johnson has provided this page of colonial amendments to Warhammer 40K. These also would be a good way to introduce fantasy and science fiction wargamers to historical miniatures games.
