It's easy to understand Duquesne's hatred of the British, in general and Kitchener in particular, and why he wanted credit for Kitchener's demise. So much of what was wrong with the Empire was displayed in the 2nd Boer war. Breaker Morant was shot for killing guerrilla combatants. Horatio Kitchner killed 26,000 woman and children and was made an Earl. The only true British hero of the war was Emily Hobhouse.
