In this episode we talk to author and former RAF Tornado Navigator and Gulf War prisoner-of-war John Nichol. Over one million British Empire soldiers were killed during the First World War. More than a century later, more than half a million still have no known grave. 

The scale of the fighting, the destructive power of high explosive, and the combination of relentless military engagement and glutinous mud meant that many of the dead were never recovered or identified. Names were left without bodies, and bodies, or fragments of bodies, without names.

In an emotional personal journey, John uncovers the dramatic story of the Unknown Warrior who lies in Westminster Abbey, and our nation’s deep-seated need to honour and mourn the fallen.
