The Long Tom Pass was built between Lydenburg and Sabie as an alternative route for the waggoners of the 1800s to get through to the Mozambican port of Lourenco Marques (now Maputo) for trade. It took the wagons 10 days to get from here to the coast. Now, it's a simple matter of hours – border post protocol included – if you go via the Long Tom Pass.
At the top of the Long Tom Pass in Mpumalanga is a large cannon called The Long Tom. That was the British name for this Boer-operated field gun that fired a 38kg shell for 10km and was the bane of British generals and their brigades.
