This Remembrance Sunday was a particularly proud and poignant day for one group of relatives of servicemen killed in wartime.
They are the families of more than 300 men who were shot at dawn for cowardice or desertion during the First World War.
The families have long argued that the men were the victims of an injustice, that they were not cowards but were deeply traumatised or shell-shocked.
Their appeals to have the men pardoned were repeatedly turned down but this year the government unexpectedly relented and 306 men have been pardoned.
This programme tells the story of the long campaign to resolve a dark episode in British history.
