1. From cavalry to beasts of burden - how their roles changed

WWI horses used for transport
  • Many horses were initially used as traditional cavalry horses but their vulnerability to modern machine gun and artillery fire meant their role changed to transporting troops and ammunition.
  • Because military vehicles were relatively new inventions and prone to problems, horses and mules were more reliable - and cheaper - forms of transport. 
  • Thousands of horses pulled field guns; six to 12 horses were required to pull each gun.

2. How the numbers grew

  • At the start of the war, the British Army had 25,000 horses at their disposal.
  • Another 115,000 were purchased compulsorily under the Horse Mobilisation Scheme.
  • Over the course of the war, between 500 and 1,000 horses were shipped to Europe every day.

3. Looking after their welfare

  • Over the course of the war vets treated 2.5 million horses and 2 million recovered and returned to the battlefield.
  • The British Army Veterinary Corp hospitals in France cared for 725,000 horses and successfully treated three-quarters of them.
  • A typical horse hospital could treat 2,000 animals at any one time. 
  • Well-bred horses were more likely to suffer from shell shock and be affected by the sights and sounds of battle than their less refined compatriots, who could be taught to lie down and take cover at the sound of artillery fire.
  • One-quarter of all deaths were due to gunfire and gas; exhaustion and disease claimed the rest.
  • It could take up to 12 hours to clean the horses and their harnesses in muddy conditions.

4. They used dummy horses too

  • Horse carcasses were a common feature at the front, and were sometimes used by soldiers as impromptu barriers.  Thus the French came up with a cunning plan - why not use hollowed-out dummy horses as observation posts? They made these dummies out of papier-mâché and built them large enough for a man to crawl inside and poke a gun through. A telephone wire was even run up from inside the horse back to the trenches so the horse lodger could report back on German movements.
  • Though the Germans soon twigged what was afoot when a French sniper was spotted climbing out of a horse, the method grew in popularity and was a regular feature on the battlefield for the duration of the war.

6. Let them eat oat cakes

  • Horse fodder was the single largest commodity shipped to the front by some countries, including Britain. The manufacturers of Quaker Oats put in a bid to supply army horses with cakes baked from compressed oats and molasses, but this proposal was dismissed as too extravagant.

7. Where is the hoof?

  • Horses were considered so valuable that if a soldier's horse was killed or died he was required to cut off a hoof and bring it back to his commanding officer to prove that the two had not simply become separated.

8. The loss of life

  • Fearing their horses would face terrifying conditions at war, some owners took the drastic measure of humanely putting their animals down before the army could seize them. 
  • In a single day during the Battle of Verdun in 1916, 7,000 horses were killed by long-range shelling on both sides, including 97 killed by single shots from a French naval gun.
  • Losses were particularly heavy among Clydesdale horses, which were used to haul guns.
  • Britain lost over 484,000 horses - one horse for every two men.

The Animals in War Memorial is a war memorial in Hyde Park, London, commemorating the countless animals that have served and died under British military command throughout history. It was designed by English sculptor David Backhouse and unveiled in November 2004 by Anne, Princess Royal.
