The Boer War also introduced "concentration camps" to the world.
The Spanish used a similar system in Cuba a few years earlier, and the US used a similar system in the Phillipines at the same time. As Thrawn points out, such camps had been used against aboriginal populations a lot earlier (for example, American Indians)
Don't forget Lazs, the British didn't exactly park their whole army in the Transvaal,
Yes, I believe the Boers had about a 4 to 1 advantage in soldiers in the first Boer war, and in the second they carried out guerrila attacks, because they couldn't win major battles.
In the end, of course, they lost the guerilla campaign as well.
The brits exploited the Boer love of family by rounding up the Boer women and children and putting em into concentration camps to starve and die of disease and the elements.
It was actually the end of the concentration camp policy that defeated the Boers.
The camps had been set up to house Boer families who had had their farms destroyed, either in fighting or to prevent them supplying the guerillas. In late 1901 Kitchener ordered no more Boer families to be brought in, unless they were starving, and the Boer guerillas had to look after their civilians. By the Boer congress of March 1902 they were complaining that the British were turning their families away from the camps.
