In this special episode we join The Army Benevolent Fund’s “Frontline Walk” from the Somme to Ypres, via Vimy Ridge. As we follow the fundraisers’ we visit a vast German Cemetery near Arras and hear from a walker whose relative is buried along the route. In Polygon Wood, we find an Australian grave with an emotional family inscription, and follow the route of the Canadians as they cross the Ravebeek in terrible conditions during the Battle of Passchendaele. We end with an emotional interview with Alix Hale, who father Mark was killed in action in Afghanistan in 2009.
