These camps were often located in miserable terrain with discarded military tents serving each as the housing for multiple families. Everyone slept on the ground as there were no beds and there were only the most rudimentary sanitary or medical facilities. No fruit, vegetables, or milk was provided by their captors and the detained population often succumbed to disease and malnourishment.
The Boer War (1899-1902): The British controlled most of southern African what they didn't control was controlled by the Boers---Dutch descendants of early African colonists---after finding major mineral deposits on Boer land, the British invading resulting in the Boer Wars. The British took the Boer territories and created the White controlled political system that would dominate South Africa for more than 100 years.
Personal recollections testify that there were beatings and kicking of "Undesirables" in the camps by the British soldiers. The British burned the homesteads, killed livestock and destroyed crops. Women and children of burghers in the field were labeled "Undesirables" treated much worse than those of men who had surrendered.
