Trooper Arthur Fischer was one of the original members of Roberts' Horse, joining on 15.12.1899 when it was still known as the 2nd South African Light Horse. Its name was changed in January 1900 at the request of its members as a compliment to the new Commander-in-Chief. It was immediately thrown into the fray, took part in the relief of Kimberley and Paardeberg and only through its adroit handling by Lieutenant-Colonel Dawson, Officer Commanding, avoided decimation at Sannah's Post. Fischer was discharged medically unfit in July 1900.
