Leverage for horses

This diagram from a US army manual issued in 1916 shows the standard loading for a pack animal.

It is time to review how draft animals are connected to their loads. The simplest example would be a pack horse or a mule, in the days when mule trains carried clay to pottery workshops. The Devon clay that was transported this way earned the name of ball clay, since it was shaped into large balls and carried in a double bag carried on the animal’s back, where a saddle might otherwise have gone. Pack animals are often quite light, enabling them to cross rugged terrain, where roads were not available. It is important to keep a regularly updated note of a draft animal’s weight, taking care not to expect them to carry more than 15-20% of their current weight.

Take a half ton horse, hitch it up to loaded lighter, and you’re off!

Carts redistribute a load, but slowing down or stopping can be more demanding, particularly when going downhill. The most efficient means of transport, particularly for heavy consignments such as building supplies, is the canal barge. This can be hauled by a (large) single horse, even when loaded with several tonnes of goods.

Verdun: the turning point

When the first world war started in 1914, the world’s armies were accustomed to seeing imposing troops on horseback leading charges across open ground and engaging in the thick of the action. By the end of the battle of Verdun, in December 1916, the former cavalry units were to be found changing their sabres for machine guns and driving armoured vehicles instead of riding horses.

Verdun marked a pivotal point in the first world war, claiming so many lives that it was known as the “meat grinder”. To this day, farmers are still digging up horseshoes from the former battlefield. After decades of developing increasingly powerful artillery and with the arrival of mechanised warfare, the twentieth century battlefield witnessed the massacre of draft animals  on a scale never previously imagined. 

The British Army did not appreciate just how few horses it could afford to lose. Moving artillery pieces, carrying munitions to gun emplacements, at the turn of the century, modern armies could not operate without horses. From the front line to the billets, draft animals were ever-present. The first world war was deadly: on a particularly bad day, over 7,000 were killed in a conflict that lasted for years and claimed millions of equine lives around the world. Of these, nearly half a million were attached to the British army in some way. Faced with the eye-watering costs of procuring and transporting horses, the government set up the British army veterinary corps. Its skilled veterinary surgeons treated nearly three quarters of a million draft animals.

Despite going to war with extra horses to keep the army supplied, the German government had problems procuring fodder and some animals starved to death. Importing horse-related items was particularly difficult since traders were refusing to take German currency.

Around the world, the heavy losses of working horses created strong demand for alternative transport capacity. In Britain, the War Office pushed up demand for commercial vehicles by dumping 6,000 war surplus lorries and trucks on the market at bargain prices. It is hard to gauge the full extent of wartime losses and their impact on the wider economy, but many businesses that used to be horse-based changed to offer engineering and driving skills.

Horses were among the first animals to be domesticated during millennia of prehistory. You can be sure that the energy needed to build the monuments and cities of antiquity came from horses, mules and donkeys, if it did not come from slaves.

Horse sense

A cornerstone of Urban Food Chains crystallised this evening. Fundamental to the structure of a supply chain is the basic unit of transport and energy. Taking three major themes of this blog, let’s unpack the topic. First, before the dawn of time, generations of early agriculturists worked for millennia to domesticate species and crops that we would recognise today. They also tamed fire, an evolutionary trump card. Their lasting achievement was to breed forerunners of today’s strategic ungulates: cows, pigs, sheep and horses. Fast forward to the early twentieth century, when the first world war slaughtered millions of draft animals.

This high tech cull of horses, in particular, damaged the bedrock of the agricultural world. Livestock numbers would take decades to restore, if indeed there was either the economic resources or the political will to do so. The first world war was a reset that made way for change on a global scale, for humans and animals alike. Thousands of years spent establishing stable working relationships turned to dust in the heat of battle.

The penny dropped when I read Christopher Turnor, an author of the time, complaining that the UK had too many pastures, they were blocking food production. The origins of all this empty grassland are to be found in Edwardian England, but the wartime cull of draft animals accelerated the trend. The rest is not so much history as a race to plug the economic gaps left by the ravages of war.
