Rhodes used this document in 1890 to justify sending the Pioneer Column, a group of Europeans protected by well-armed British South Africa Police (BSAP) through Matabeleland and into Shona territory to establish Fort Salisbury (present-day Harare), and thereby establish company rule over the area. In 1893 and 1894, with the help of their new Maxim guns, the BSAP would go on to defeat the Ndebele in the First Matabele War. Rhodes additionally sought permission to negotiate similar concessions covering all territory between the Limpopo River and Lake Tanganyika, then known as "Zambesia".
