Diamond Hill (Second Boer War).

Fought June 11 and 12, 1900, when General Botha, with the main Boer army of 15,000 men, strongly entrenched about 15 miles from Pretoria, was attacked by Lord Roberts with 17,000 men and 70 guns, and driven from his position. The Boer lines were so extended that three distinct actions were in progress at the same time. The British lost 25 officers and 137 men killed and wounded.
