Snow in the reserve trenches, Western Front, during World War I. The sheer misery of the trenches in the winter is well illustrated by this photograph of troops walking along a reserve trench. The men, huddled into their greatcoats, are black against the snow around the trench. THE HEROES of World War One have been brought into the twenty-first century thanks to a series of stunning colourised images to mark the 100th anniversary of the end of the war. Striking pictures show men hauling a howitzer out of the mud at Beaucourt sur Ancre, four British soldiers using a fallen tree-trunk as a temporary bridge over the River Ancre and six soldiers looking out of a dugout on the Western Front. Other vivid colour photographs show soldiers digging a trench viewed between strands of barbed wire, officers showing a map to their men at the Somme in France and infantry waiting in a trench for their turn to advance. The original black and white photos were expertly colourised by electrician Royston Leonard (56) from Cardiff, Wales. Royston Leonard / mediadrumimages.com
