Infantry waiting in a trench for their turn to advance, while others to the right are already advancing. There is a tank in the background in front of the infantry, so the image must have been taken after 15 September 1916, the first time that tanks were used in battle. It probably dates to after the Cambrai offensive of 1917, when they were used with greater success. 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
