The Great Emu War

The only war fought between humans and animals was the Australian military vs Emus. In 1932, the Australian military started “The Great Emu War” where they tried to cull emus with machine guns. Six days after the first engagement, 2,500 rounds of ammunition had been fired and no emu was killed. The end result was a forced retreat of Australian troops when they realized they could not kill the Emus cost-effectively due to the birds' positioning tactics.
