By the end of the First World War, the whereabouts of more than half a million British soldiers were unknown. Most were presumed dead, lost forever under the battlefields of northern France and Flanders. This, however, was only the beginning of a search that would span a century: from the department set up to investigate the fate of missing comrades in the war's aftermath, to the present day, when DNA profiling continues to aid efforts to recover, identify and honour these men. As the rest of the country found ways to repair and move on, countless families were consumed by this mission, undertaking arduous, often hopeless, journeys to discover what happened to their husbands, brothers and sons. In 'The Searchers', Robert Sackville-West brings together the extraordinary, moving accounts of those who dedicated their lives to the search for the missing.
