One was a giant of muscle and mud, hauling guns through terrain no machine could cross. The other was small enough to sit in your palm, carried underground to save soldiers from gas no one could see. Neither animal chose to be there.
Both animals were pulled into a war they had no say in. Here's a quick introduction before we dig into their stories.
Slow, powerful, and unstoppable in mud where horses gave up — oxen hauled supply wagons and heavy guns for the British, French, Russian and Austro-Hungarian armies.

Small enough to carry in one hand, sensitive enough to detect deadly gas before any human could — canaries rode into tunnels and bunkers as living early-warning systems.
Read the full story →Oxen were used by several armies, including the British, French, Russian and Austro-Hungarian forces, to pull heavy wagons of supplies. While horses and mules did most of the war's hauling work, oxen were brought in specifically for the terrain those animals struggled with: thick mud, steep or rocky ground, and routes far from any road.
Oxen were far slower than horses and ate much more food, so armies didn't rely on them for everything. But their raw strength meant they could still drag heavy wagons and artillery through conditions that brought faster animals to a halt.
Life for a military ox was hard labour in a war zone: long days pulling enormous loads, exposure to shellfire and disease near the front line, and exhausting treks across broken ground. Thousands of horses, mules, donkeys and oxen were killed, wounded, or worn down by fatigue and disease during the war. Britain's Army Veterinary Corps treated sick and injured animals where it could, but a large number could not be saved.
There's a strong case for yes: oxen were made to labour for long hours in dangerous conditions, with no choice in the matter and no understanding of why. They were valued for what they could pull, not cared for simply for their own sake.
At the same time, armies did spend real effort keeping draught animals alive and working — veterinary hospitals existed, and a healthy ox was worth protecting. Whether that counts as "care" or just careful use of a valuable resource is worth deciding for yourself.
Canaries were used by the British military and others to detect poisonous gas in tunnels and bunkers. Carried in cages by specialist "tunnelling companies," they warned soldiers of toxic air — especially deadly carbon monoxide left behind after underground explosions — long before a human could sense any danger.
Canaries have a much faster metabolism than humans, so gas affects them first and visibly. If a bird became sick, stopped singing, or fell off its perch, that was the signal: get out, now. Mine rescue stations even kept birds' claws trimmed so they couldn't grip too tightly — making it obvious the moment a canary lost its balance.
The method wasn't invented for the war. It came from scientist John Haldane, who investigated a coal mine explosion at Tylorstown in Wales in 1896 and proposed using small, sensitive animals as living gas detectors. By the First World War, specialist rescue teams — sometimes called "Proto men" after their breathing apparatus — carried around six canaries and mobile cages into the tunnels dug beneath enemy lines.
Here the tension is sharp: canaries were placed in some of the most dangerous environments of the war and could be killed by the very gas they were warning soldiers about. Their entire "job" depended on them getting sick before a person did.
Rescue teams did try to save them — special cages with oxygen cylinders could revive a canary after it collapsed, and a bird could be used again once recovered. Even so, they were kept specifically so they would suffer first. Whether their life-saving role justifies that is a fair question to sit with.

"Exploitation" means using someone or something purely for your own benefit, without much regard for what it costs them. Applying that word to animals in wartime is genuinely debatable — here's the case on both sides.
Neither animal had any choice. Oxen were worked to exhaustion in dangerous places; canaries were deliberately put in harm's way because their suffering was the whole point of the system. They bore the risk so humans didn't have to.
Armies also invested in keeping these animals alive — veterinary hospitals for draught animals, oxygen-cage revivals for canaries. That doesn't erase the danger they were put in, but it shows their treatment wasn't simple neglect either.
