The Emu War, Australia, land of “oh fucking hell what the fucking shit is that thing” and “Oh sweet merciless god what the fucking fuck fuck fuuuck” versus a flightless bird.
The Australian government attempted to curb the emu population around marginal farmland, why the fuck they decided to farm marginals is frankly beyond me, but hey.
They used Lewis machine guns and failed, turns out that emus don’t tend to attack farmland in massive waves of birds, huge herds of flightless menaces, they are just grounds of birds.
The whole thing was a magnificent failure, ordered by some idiotic politician without consulting with say: An ornithologist, who could have told him that machine guns are useless. The bounty system put in place later was much more effective.
