The Pioneer Column was a force raised by Cecil Rhodes and his British South Africa Company in 1890 and used in his efforts to annexe the territory of Mashonaland, later part of Southern Rhodesia (now Zimbabwe).
Rhodes was anxious to secure Matabeleland and Mashonaland before the Germans, Portuguese or Boers did. His first step was to persuade the Matabele King Lobengula, in 1888, to sign a treaty giving him rights to mining and administration (but not settlement as such) in the area of Mashonaland which was ruled by the King by use of coercion and murderous raids involved tribute-taking and abduction of young men and women. Using this Rudd Concession (so called because Rhodes's business partner, Charles Rudd, was instrumental in securing the signature) between Rhodes' British South Africa Company (allegedly on behalf of Queen Victoria though without any official knowledge or authority) and Lobengula, he then sought and obtained a charter from the British government allowing him to act, essentially although in a limited way, with the government's consent. The next step was to occupy the territory.
Rhodes's military advisers estimated that it would take 2,500 men and about one million pounds to win the war that would, they thought, inevitably result when Lobengula realised that Rhodes meant not only to mine but also to occupy his land. Frank Johnson, a 23-year-old adventurer, however, undertook to deliver the territory in nine months with a mere 250 men for £87,500. Frederick Selous, a hunter with close knowledge of Mashonaland, agreed to join the effort as guide. Johnson published recruitment notices in Kimberley offering each volunteer 1,200 hectares (3,000 acres) of land and 15 mining claims (aggregating about 8.5 hectares (21 acres)). On the advice of Rhodes, Johnson selected for his column, from thousands of applicants, mostly the sons of rich families, so that if they were, indeed, imperilled by Lobengula their families would be more likely to enlist British government support for their rescue. Johnson's column eventually consisted of 180 civilian colonists, 62 wagons and 200 volunteers (who ultimately formed the nucleus of what became the British South Africa Police). A further party of 110 men, 16 wagons, 250 cattle and 130 spare horses later attached itself to the column. The troopers were equipped with Martini-Henry rifles, revolvers, seven-pound field guns and Maxim machine guns, as well as an electric searchlight (which they later used to good effect to intimidate Matabele warriors shadowing the column).
