 Some members of the Committee had been instrumental in the preparation for the Jameson Raid.Leander Starr Jameson had been in charge of Matabeleland when he overstepped his authority and invaded Transvaal with 1 500 troops, greatly exacerbating the many adverse conditions that would lead to both the Second Matabele War and the Second Boer War.Upon Jameson's capture and surrender to the forces of the South African Republic (the Transvaal) in December 1895, the Committee took charge of the peace and security of Johannesburg, before conceding control back to the Boer authorities some days later.
