The Emu War, which took place in Australia in 1932, is a unique and somewhat humorous event in history. It involved the Australian military attempting to cull the emu population in Western Australia. Despite the use of machine guns, the emus proved to be surprisingly resilient and elusive.
To answer the question directly: no people died in the Emu War. The conflict was between the Australian military and the emus, and there were no human casualties reported. The war is often remembered more for its absurdity than for any serious consequences.
