Soldiers fired 10,000 rounds and lost—to which enemy?

The Wheat Crisis That Launched a War

In October 1932, Western Australia faced an agricultural emergency. Twenty thousand emus had migrated inland after their breeding season, descending on farmland around Campion and Walgoolan in search of water and food. The birds trampled fences, devoured wheat crops, and created gaps that let rabbits pour through, compounding the damage. World War I veterans who had been given these marginal lands under soldier-settlement schemes watched their livelihoods disappear under the onslaught. Federal politicians, pressuring the government for help, framed the crisis in military terms: if the government had deployed soldiers to fight rabbits with poison, surely it could deploy them against emus with guns. On October 17, Minister of Defence Sir George Pearce approved what newspapers would mockingly call the Great Emu War, dispatching a unit with two Lewis machine guns and ten thousand rounds of ammunition.

The Campaign That Became a Rout

Major G.P.W. Meredith of the Seventh Heavy Battery of the Royal Australian Artillery arrived with Sergeant S. McMurray and Gunner J. O'Halloran, confident the operation would take days at most. The first engagement on November 2 near Campion seemed to confirm that confidence: the soldiers spotted a mob of approximately fifty emus and opened fire. But emus can sprint at nearly fifty kilometers per hour and pivot mid-stride, scattering in every direction the moment shooting began. Meredith's after-action reports noted that the guns jammed repeatedly in the dust, and by the time they were cleared the birds had vanished into the scrub. A second attempt to ambush a flock at a dam ended when an advance scout emu detected the soldiers and led the entire group away before the guns could be positioned. Over six days, the unit expended 2,500 rounds and estimated they had killed fewer than two hundred birds—a ratio of more than twelve bullets per emu, and even that figure was likely optimistic.

The Tactical Genius of Flightless Birds

The emus' success lay not in intelligence but in evolutionary adaptation. Ornithologist Dominic Serventy later noted that emus travel in small, loosely coordinated groups rather than dense flocks, so a machine-gun burst that might mow down a tightly packed target instead hit empty ground between scattered individuals. Their leg muscles, built for marathon endurance rather than straight-line speed, let them execute sudden direction changes that made lead-targeting nearly impossible. When Meredith tried mounting a Lewis gun on a moving truck to chase the birds, the rough terrain bounced the barrel so violently that the gunner couldn't aim, and the emus simply outpaced the vehicle across the open scrubland. One ornithologist observing the operation told a Melbourne newspaper that if the emus had a military commander, he deserved a medal—the birds consistently split into smaller units when under fire, regrouped at a distance, and resumed their crop-raiding within hours. By November 8, the unit had been withdrawn after expending nearly all its ammunition, and the emu population was effectively unchanged.

The Legacy of a Feathered Victory

The failed campaign became an instant source of ridicule in Australian and international press. Canberra parliamentarians demanded explanations for the waste of military resources, and one opposition member quipped that the emus should be granted war medals since they had clearly won every engagement. Major Meredith's official report acknowledged the operation's futility, noting that
