I learned recently that Spain used 'reconcentration' camps during the war, and America had their own version of a camp in the Philippines. I'd like to know if others exist or have existed. Thank you.
The concentration camps used by Nazi-Germany were very different from those used in in the Spanish-American War, the Boer War and the Philippine-American War. I've written a more extensive post about the use of 'concentration camps' in counterinsurgency here. You are free to ask any additional questions!
