More than 9 million soldiers died as a result of the First World War, a deadly conflict that paved the way for revolutions and major political upheaval in the 20th century.

Images of victory and pride have been circulated widely since the fighting ended in 1918, but lesser known are the pictures which show how troops and civilians lived their everyday lives while the bloodshed unfolded.  On the 100th anniversary of the outbreak of the Great War , the Moscow House of Photography has prepared a large-scale international project called 'The War That Ended Peace' that brings together a collaboration of images from the world’s leading museums, alongside public and private archives. The stunning photographs depict the war through the eyes of those who fought on all sides of the conflict. It includes prisoners of wars staring through the barbed wire fences of German camps, wounded soldiers with limbs amputated walking through Poland, and families attending private funerals of the fallen in France. When you think of First World War footage, chances are you conjure up grainy images of soldiers and jumpy footage of the trenches. But a new 3D film by Lord of the Rings director Peter Jackson is set to bring the conflict to life in a way never seen before. The Oscar-winner has restored and colourised 100-year-old footage from the Imperial War Museum's vast archive, and early photos suggest the results will be remarkable. One comparison shot shows the dramatic transformation from poor quality black-and-white scenes to clear colour images, while another shows the radically sharpened faces of our troops.

Soon, however, the deadly terrain that evolved around trench warfare rendered cavalry attacks nearly useless on the Western Front. But the need for constant resupply, movement of new heavy weaponry, and the transport of troops demanded horse power on a massive scale -- automobiles, tractors, and trucks were relatively new inventions and somewhat rare. British and French forces imported horses from colonies and allies around the world, a near-constant flow of hundreds of thousands of animals across the oceans, headed for war. One estimate places the number of horses killed during the four years of warfare at nearly 8 million. Other animals proved their usefulness as well: Dogs became messengers, sentries, rescuers, and small beasts of burden. Pigeons acted as messenger carriers, and even (experimentally) as aerial reconnaissance platforms. Mules and camels were drafted into use in various war theatres, and many soldiers brought along mascots to help boost morale. Only a couple of decades later, at the onset of World War II, most military tasks assigned to animals were done by machines, and warfare would never again rely so heavily on animal power. 1 A single soldier on his horse, during a cavalry patrol in World War I. At the start of the war every major army had a substantial cavalry, and they performed well at first. However, the development of barbed wire, machine guns and trench warfare soon made attacks from horseback far more costly and ineffective on the Western Front. Cavalry units did prove useful throughout the war in other theatres though, including the Eastern Front, and the Middle East.

The Boston Bull Terrier started out as the mascot of the 102nd Infantry, 26th Yankee Division, and ended up becoming a full-fledged combat dog. Brought up to the front lines, he was injured in a gas attack early on, which gave him a sensitivity to gas that later allowed him to warn his soldiers of incoming gas attacks by running and barking. He helped find wounded soldiers, even captured a German spy who was trying to map allied trenches. Stubby was the first dog ever given rank in the United States Armed Forces, and was highly decorated for his participation in seventeen engagements, and being wounded twice.

When Europe's armies first marched to war in 1914, some were still carrying lances on horseback. By the end of the war, rapid-fire guns, aerial bombardment, armored vehicle attacks, and chemical weapon deployments were commonplace. Any romantic notion of warfare was bluntly shoved aside by the advent of chlorine gas, massive explosive shells that could have been fired from more than 20 miles away, and machine guns that spat out bullets like firehoses. Each side did its best to build on existing technology, or invent new methods, hoping to gain any advantage over the enemy. Massive listening devices gave them ears in the sky, armored vehicles made them impervious to small arms fire, tanks could (most of the time) cruise right over barbed wire and trenches, telephones and heliographs let them speak across vast distances, and airplanes gave them new platforms to rain death on each other from above. New scientific work resulted in more lethal explosives, new tactics made old offensive methods obsolete, and mass-produced killing machines made soldiers both more powerful and more vulnerable. 1 American troops using a newly-developed acoustic locator, mounted on a wheeled platform. The large horns amplified distant sounds, monitored through headphones worn by a crew member, who could direct the platform to move and pinpoint distant enemy aircraft. Development of passive acoustic location accelerated during World War I, later surpassed by the development of radar in the 1940s.(National Archives) 2 An Austrian armored train in Galicia, ca, 1915.
