A great trek was projected for the north, but fortunately it miscarried.

To the east they raided Zululand, and succeeded, in defiance of the British settlement of that country, in tearing away one third of it and adding it to the Transvaal.

To the west, with no regard to the three-year-old treaty, they invaded Bechuanaland, and set up the two new republics of Goshen and Stellaland.
So outrageous were these proceedings that Great Britain was forced to fit out in 1884 a new expedition under Sir Charles Warren for the purpose of turning these freebooters out of the country.

It may be asked, why should these men be called freebooters if the founders of Rhodesia were pioneers?
The answer is that the Transvaal was limited by treaty to certain boundaries which these men transgressed, while no pledges were broken when the British power expanded to the north.

The upshot of these trespasses was the scene upon which every drama of South Africa rings down.
