I would like to use some auxileries (spelling?) as well both with firearms and without, which tribes were more friendly towards the British?
The Masai served as auxiliaries for the Brits against such foes as the Nandi, the Kikuyu, and that other warlike tribe of East Africa: Kaiser Wilhelm II's Germans.
When they weren't fighting the British, some Nandi "Friendlies" also fought for
them against their traditional enemies, as did the Kavirondo.
