The Delville Wood South African National Memorial is a World War 1 memorial to all South Africans who fell during the Great War including the African volunteers of the South African Native Labour Corps and the victims of the SS Mendi. It is the only memorial dedicated to the South African Forces and their role in the Battle of Delville Wood. The battle was the debut action of the South African Forces on the Western Front and is considered an example of supreme sacrifice and heroism. It was also the most costly that the South African Forces experienced during their involvement in the War. Included in the memorial is an Altar Stone in commemoration to the South African losses during the 2nd World War.
