The Battle of Modder River (Afrikaans: Slag van die Twee Riviere, lit.'Battle of the Two Rivers', fought near the confluence of the Modder and Riet Rivers) was an engagement in the Boer War, fought at Modder River, on 28 November 1899. A British column under Lord Methuen, that was attempting to relieve the besieged town of Kimberley, forced Boers under General Piet Cronjé to retreat to Magersfontein, but suffered heavy casualties altogether.
