South Africa 1899–1902

The Second Boer War ( af, Tweede Vryheidsoorlog, , 11 October 189931 May 1902), also known as the Boer War, the Anglo–Boer War, or the South African War, was a conflict fought between the British Empire and the two Boer Republics (the South African Republic and the Orange Free State) over the Empire's influence in Southern Africa from 1899 to 1902. Following the discovery of gold deposits in the Boer republics, there was a large influx of "foreigners", mostly British from the Cape Colony. They were not permitted to have a vote, and were regarded as "unwelcome visitors", invaders, and they protested to the British authorities in the Cape. Negotiations failed and, in the opening stages of the war, the Boers launched successful attacks against British outposts before being pushed back by imperial reinforcements. Though the British swiftly occupied the Boer republics, numerous Boers refused to accept defeat and engaged in guerrilla warfare. Eventually, British scorched earth policies, and the poor conditions suffered in concentration camps by Boer women and children who had been displaced by these policies, brought the remaining Boer guerillas to the negotiating table, ending the war.

The conflict broke out in 1899 after the failure of the Bloemfontein Conference when Boer irregulars and militia attacked colonial settlements in nearby British colonies. Starting in October 1899, the Boers placed Ladysmith, Kimberley, and Mafeking under siege, and won a string of victories at Colenso, Magersfontein and Stormberg. In response to these developments, increased numbers of British Army soldiers were brought to Southern Africa, and mounted largely unsuccessful attacks against the Boers. However, British military fortunes changed when their commanding officer, General Redvers Buller was replaced by Lord Roberts and Lord Kitchener, who relieved the three besieged cities and invaded the two Boer Republics in early 1900 at the head of a 180,000-strong expeditionary force. The Boers, aware they were unable to resist such a large force, chose to refrain from fighting pitched battles, allowing the British to occupy both republics and their capitals, Pretoria and Bloemfontein.

Boer politicians, including President of the South African Republic Paul Kruger either fled the region or went into hiding; the British Empire officially annexed the two republics in 1900. In Britain, the Conservative ministry led by Lord Salisbury attempted to capitalise on British military successes by calling an early general election, which was dubbed by contemporary observers a "khaki election". However, numerous Boer fighters took to the hills and launched a guerrilla campaign against the British occupational forces, becoming known as ''bittereinders''. Led by prominent generals such as Louis Botha, Jan Smuts, Christiaan de Wet, and Koos de la Rey, Boer guerrillas launched a campaign of hit-and-run attacks and ambushes against the British, which would continue for two years.

The Boer guerrilla campaign proved difficult for the British to defeat, due in part to British unfamiliarity with guerrilla tactics and extensive support for the guerrillas among the civilian population in the Boer Republics. In response to continued failures to defeat the Boer guerillas, British high command ordered several scorched earth policies to be implemented as part of a large scale and multi-pronged counterinsurgency campaign; a complex network of nets, blockhouses, strongpoints and barbed wire fences was constructed, virtually partitioning the occupied republics. British troops committed several war crimes and were ordered to destroy farms and slaughter livestock to deny them to Boer guerillas. Over a hundred thousand Boer civilians (mostly women and children) were forcibly relocated into concentration camps, where 26,000 died of various causes, mostly starvation and disease. Black Africans in the same areas were also interned in concentration camps as well to prevent them from supplying the Boers; 20,000 died in the camps as well, largely due to the same causes as in the case of their Boer counterparts.

In addition to these scorched earth policies, British mounted infantry units were deployed to track down and engage individual Boer guerilla units; by this stage of the war, all battles being fought were small-scale skirmishes. Few combatants on either side were killed in action, with most casualties coming via disease. Lord Kitchener began to offer generous terms of surrender to remaining Boer leaders in an effort to bring an end to the conflict. Eager to ensure their fellow Boers were released from the concentration camps, the majority of Boer commanders
