The Unknown Warrior with John Nichol

Over half a million British soldiers killed during the First World War are still missing. More than a century later, they have no known grave or their body has never been identified. In a deeply personal journey, John Nichol uncovers the story of one of them: the Unknown Warrior who lies in Westminster Abbey.

Few are better placed to reflect on what it means if a person is lost in combat. As a Royal Air Force navigator during the first Gulf War, John was shot down. He was captured, tortured and held as a prisoner of war, facing the prospect that he might never return home.

I spoke to him about every soldier's worst nightmare: to be forgotten.
