Prior to operations against the German held Southwest Africa, the South African Government had to quell an anti-British revolt in the country. It had only been a little over a decade since the last Boer War and the tension between the British and Boers still ran high in some areas. In 1914 the South African army and population split over the impending attack on Southwest Africa.

Anti-government forces (2,000) mostly Boers were defeated. by Government forces at the Battle of Mushroom valley on November 12 1914. The last major attack by Anti-government forces occurred as they attacked Upington in January 1915. Consolidation operation continued until the last of the rebels surrendered in 1915.

For scenarios, I would field mostly men dressed in a Boer style but some men had by in the Territorial forces so may have worn parts of that uniform.

Between April and July of 1915, the 50,000 man South African force overwhelmed the 9,000 German defenders in Southwest Africa.

Units of the South African Defense Force included: the five Mounted Rifle Regiments formed from mainly the police forces of the various territories. In 1915 two regiments were raised as ‘Imperial units’ for service in other parts of Africa. These were the 1st and 2nd South Africa Rifle Regiments. The Active Citizen Force was raised for the campaign against Southwest Africa and included six Mounted Rifle regiments and twelve Infantry regiments.

For overseas service the South Africans provided a Brigade of four regiments. The 1st South African Infantry (Cape region), the 2nd South African Infantry (Natal and Orange River) , the 3rd South African infantry (Transvaal) and the unusual 4th South African Scottish Infantry (Scot settlers in the Transvaal, ACF Scottish unit and the Cape Town Highlanders).
