The Emu War, also called the Great Emu War, was a military operation in Australia. The army tried to kill many emus because they were pests. The war was fought in late 1932. Farmers were having trouble with the many emus invading the Campion district of Western Australia. Soldiers used Lewis guns to try to kill the emus, a large flightless bird. The media called it the "Emu War" when describing the military action. The army did kill some birds. The emu population stayed large and continued to destroy crops.
