"Invention of the concentration camp by England during the Boer war."

Sorry Richard we cannot claim that or accept the blame for that. Both the Spanish (Cuba October 1896 - Gen. Valeriano Weyler - over 300,000 dead) and the USA (1899 in The Philippines - General Franklin Bell - ~298,000 dead) employed the use of "concentration camps" before we did. The British version arrived shortly after late in November 1900 - General Kitchener - ~26,000 Boer dead and ~14,000 native Africans {During the same time ~15,000 British & Empire Soldiers died in their camps} - But there again neither the Spanish or the US Army had any equivalent of Emily Hobhouse, or the Fawcett Commission to raise British public awareness of conditions in the camps, recommendations from the latter meant that a duty of care and protection was imposed on the British Military authorities in charge of the camps and mortality rates inside the camps were reduced to less than those in most towns in England.
