Two texts that give in a reasonable manner, the story of the Camps :
MARTIN Lieutenant Colonel A.C., MC, VD, BA (Cape), Hon Ph.D (Natal), a very good researcher and historian. The Concentration Camps 1900-1902. Facts, Figures, and Fables. Howard Timmins, Cape Town, 1957. Hard cover, dustjacket, 109 pp., photographs. A factual account of the controversial camps issue, written as a repudiation of J.C.Otto's `Die Konsentrasiekampe' in a sane manner. Needless to say, it was greeted with derision in Nationalist circles. One very relevant point it brings out, is the very large number of deaths of children in the camps from measles, as having been no higher than the deaths of European children in the Southern African milieu, there being a world wide measles epidemic at the time.
In a similar vein, using different resources, this very hard to find due to its paper covers and deliberate removal by Afrikaan authorities; DEVITT Napier. The concentration camps in South Africa during the Anglo-Boer War of 1899-1902. Shuter & Shooter, Pietermaritzburg, 1941. Print wrappers, 60p. Puts a good case to contradict some of the "wild statements and wrong conclusions" about the camps.
The Apartheid regime did their level best to remove both books from the public domain.
Major General Sir H.H.Settle took military command of Cape Colony 1902, and appointed to deal with concentration camps, and martial law within the two colonies and two occupied States, which he did with equal effectiveness. They had not been under consolidated control, so the whole then came under his command, with military officers in complete command rather than politically appointed civilians.
There is no evidence of deliberate shortage of rations in the camps, what there was though, was the mass misappropriation of the necessities of life for the inmates. Bedding, clothes, food etc., many reported to policing authorities by the Camp Commandants, who were responsible for the camp security and the internal discipline of the inmates, all administrative and logistic matters were handled by the civilian administration. A lot of camps were very well run, some by incompetents, and some very bad! Quite a few of the civilians so employed were imprisoned for their thieving activities, none for their incompetence or sheer lack of ability. Many were Boers.
As for changing the name, it's just further acts of the nothing people to change everything in the rewriting of history. The one that amuses me the most is the push for the disbandment of The Royal Canadian Mounted Police , one of the most competent policing bodies in the world.
