Shortly after the war D. G. and J. H. van der Byl erected on Cornwall Hill a memorial to their friends who fell in the war; this is a monolith visible for miles around. Standing on a hill on the other side of the valley and known as Koppie Smuts is the obelisk where General Smuts’ ashes were strewn; a memorial service is held here each year on the Sunday nearest to the General’s birthday at the end of May. In the valley are many of the Transvaal’s indigenous trees, particularly thorn trees, and there is little doubt that this part of the valley or “kloof” was the feature which gave the farm its name more than a hundred years ago — “Doornkloof”.
