The Beja cavalry were virtually all camel mounted.
I love painting these Perry camels for some reason; much more than horses, which I hate painting.
The Beja (especially the Bisharyyin, Ammar'ar and Haddendowa tribes) were great camel breeders (as they are now) and their off white Bishari camels, bred in Kassala and the Red Sea Hills are quite distinctive. When the reconquest of the Sudan took place in 1898 the British made sure that they had Bishari camels rather than the motley cocktail Redvers Buller pulled together to populate the Desert Column.
They are comparitively small and strong and today these camels are highly prized for racing.
