In early 1880, British forces in Transvaal decided to build a fort in the village, due to its remoteness from other British South African forts, with it being from Pretoria. Marabastad and the
Zoutpansberg district had a population of 300,000–400,000 natives, along with an additional 175,000 in Waterberg. A fort was needed to control the large native population. In February 1880, two detachments of the 94th Regiment, under Captain Campbell, reached Marabastad, the first British forces to reach this part of South Africa. Within three months, the fort had been built. On 29 November 1880, Captain Campbell was ordered to march to Pretoria. Along with a company of 60 men, Campbell left for the city, leaving behind a company of 60 men in Marabastad. Campbell left Captain E.S. Brooks in command, along with Lieutenant F.G.W. Jones and Surgeon Harding, A.M.D. ==Preparations for the siege==
