In this week's episode we travel to another 'Forgotten Battlefield' of the Great War and walk the area around Loos, on the site where the 'Lone Tree' was located in 1915. Walking from Le Rutoire Farm, near the village of Vermelles, to the Lone Tree in the very heart of the 1915 Loos Battlefields. We visit battlefield cemeteries and discuss the story of Rudyard Kipling's son, John, who fell at Loos with the Irish Guards. Our object this week is a poignant photo of a young girl, a postcard lost on the battlefield.
