During the South African/Anglo-Boer War(1899-1902), the British established concentration camps in retaliation to Boer guerilla fighters. Thousands of Boer women and children and thousands of blacks and "coloured" people were interned within these camps. The conditions in the camps were unsanitary and led to the death by disease,mostly respiratory illnesses, of many of the inmates. There were outcries in Britain over the camps among Liberal members of Parliament and social reformers such as Emily Hobhouse. In response to this, the Secretary of War sent an all ladies commission to South Africa. Their final report cited unsanitary conditions and insufficient camp administration as contributing factors to the high death rates.Among their recommendations was to increase the nursing staff. The Colonial Nursing Association provided nurses for these jobs. This article uses a previously unused archival source, the case notes of the medical advisor to the Colonial Office. In 1901-1902, he examined a group of nurses going out to work in the concentration camps of South Africa. This article presents the results of the examinations of 89 nurses, three of whom were rejected, and places them in the context of medical concerns at the time.
