The location is at the head of the "Long Tom' Pass between Lydenburg and Sabie, In the old Eastern Transvaal Province of South Africa. The pass is part of the old wagon route between Delagoa Bay (Lourenzo Marques/Maputo) in Mozambique and Johannesburg. I believe that it was at this site that the last formal action of the cannon occurred before they were destroyed and the Boers changed their tactics to guerilla warfare.
