The Battle of Diamond Hill (Donkerhoek) took place on 11 and 12 June 1900 during the Second Boer War. Fourteen thousand British soldiers squared up against four thousand Boers and forced them from their positions on the hill. The British cavalry were under the command of Sir Ian Hamilton. He despatched Robert Broadwood's 2nd Cavalry brigade, which included the 10th Royal Hussars, 12th Royal Lancers and the Household Cavalry Regiment, on a Special Mission.
