In response to this summary, and in general the Boer War.
I believe that the abandonment of civilized war practices during the Boer War is a completely natural consequence of territorial war. When the British began fighting the Boers for Boer territory, it was obvious that the only way to win was to destroy the native population. This is evident in that fact that every single imperial action initiated by Europe resulted in a death toll for the native population, mostly in inhumane ways because the tie to one’s land is one of the hardest bonds to break. Holding a nation to war standards when that nation is trying to conquer territory inhabited by rebellious natives is hard because people defending their land will stop at nothing to hold their land. I believe it’s a natural consequence of war to have a inclination towards brutality when dealing with the enemy.
