Second Boer War: Boers, led by Koos de la Rey, defeat the British at the Battle of Tweebosch.

The Second Boer War, also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the two Boer republics over Britain's influence in Southern Africa.

Boers are the descendants of the proto Afrikaans-speaking Free Burghers of the eastern Cape frontier in Southern Africa during the 17th, 18th, and 19th centuries. From 1652 to 1795, the Dutch East India Company controlled the Dutch Cape Colony, which the United Kingdom incorporated into the British Empire in 1806. The name of the group is derived from Trekboer then later "boer", which means "farmer" in Dutch and Afrikaans.

Jacobus Herculaas de la Rey, better known as Koos de la Rey, was a South African military officer who served as a Boer general during the Second Boer War. De la Rey also had a political career and was one of the leading advocates of Boer independence. His death at the hands of the South African Police under controversial circumstances had a major role in sparking the Maritz rebellion.

In the Battle of Tweebosch or De Klipdrift on 7 March 1902, a Boer commando led by Koos de la Rey defeated a British column under the command of Lieutenant General Lord Methuen during the final months of the Second Boer War.

March 7 is the 66th day of the year in the Gregorian calendar; 299 days remain until the end of the year.
