on 28 november 1899, during a raid south of the tugela river in natal, joubert was thrown from his horse and suffered internal injuries. as the war went on, physical weakness led to joubert's virtual retirement, and, though two days earlier he was still reported as being in supreme command, he died at pretoria from peritonitis on 28 march 1900. sir george white, the defender of ladysmith, summed up jouberts character when he called him "a soldier and a gentleman, and a brave and honourable opponent".
