There are some quite superb 28mm figures available for this genre and of course the subject matter lends itself nicely to smaller armies. I have in mind a couple of ideas for use with Death in the Dark Continent although they are a long way off as the project list currently stands.
My knowledge of the various African campaigns in the latter half of the 19th century is limited in both scale and scope to the usual suspects - the Zulu War, elements of the Sudan campaign (included purely as it took place on the same continent!), some of the French adventures and the Great War so when I saw that Chris Peers had written a book that serves as an excellent reference source to his rules my only questions was how soon could I get a copy?
I can do no more than quote the Amazon advert for the above:
"In The African Wars Chris Peers provides a graphic account of several of the key campaigns fought between European powers and the native peoples of tropical and sub-tropical Africa in the late nineteenth and early twentieth centuries. His pioneering and authoritative study describes in vivid detail the organization and training of African warriors, their weapons, their fighting methods and traditions, and their tactics. He concentrates on the campaigns mounted by the most successful African armies as they struggled to defend themselves against the European scramble for Africa. Resistance was inconsistent, but some warlike peoples fought long and hard - the Zulu victory over the British at Isandhlwana is the best known but by no means the only occasion when the Africans humiliated the colonial invaders."
Certainly worth adding to the collection for some ideas.
