Moorosi was to die in unclear circumstances on Mount Moorosi (Sesotho "Thaba Moorosi") in 1879, after a protracted nine-month siege by the British, Boer (i.e. Afrikaner farmers) and Basotho forces (including the military participation of the Cape Mounted Riflemen). This siege is often referred to as "Moorosi's Rebellion". The issue that triggered the siege was alleged livestock theft in the Herschel area. In the aftermath of the siege, Phuthi people dispersed widely over what is contemporary southern Lesotho and the northern Transkei region, to escape capture by the colonial powers. It is for this reason, it has been hypothesised, that Phuthi villages (including Mpapa, Daliwe, Hlaela, Mosifa and Mafura—all to the east of Mount Moorosi, in Lesotho) are typically found in such topographically mountainous regions, accessible only with great difficulty to outsiders).
