1. The Emu War (Australia, 1932)

Imagine a nation’s military going up against giant, flightless birds—and losing. That’s exactly what happened during the Emu War in Australia. Farmers, desperate to protect their wheat crops from thousands of rampaging emus, enlisted soldiers with machine guns to solve the problem. Despite their firepower, the emus proved too fast and resilient, outmaneuvering the troops and winning the “war.” For the full story, see Smithsonian Magazine.
