3. The Hidden Kingdom of Natagala. In 1890 the famous Professor George Nightengale accidentally discovered the Hidden Kingdom of Natagala. Our hero journeyed up to the big curve in the Merowe river that flowed out of Batal Colony and then west into the Great Desert, where he eventually found a rich, primitive culture in a hidden valley on the other side of the Great Desert; the Kingdom of Natagala. Professor Nightengale theorizes that the Natagala are related ethnically to the Matabele and Zulus.
6. German Imperial Marines and Schutztruppe. Schutztruppe (literally "protection force") was the official name of the colonial troops in the African territories of the German colonial empire from the late 19th century. Similar to other colonial armies, the Schutztruppe consisted of volunteer European commissioned and non-commissioned officers, medical and veterinary officers. Most enlisted ranks were generally recruited locally.
7. The French Foreign Legion. Some additional forces for In Her Majesty's Name include the famous French Foreign Legion. Statistics for the Legion can be found in the basic rules and the other forces I have added can easily be built using the rules and annexes.
