Details of soldiers murdered by the Nazis during the Second World War have been put together for the first time.

A series of books has uncovered details of how members of the SAS and Long-Range Desert Group were killed.

Thirteen years of research into the Roll of Honour has been done by an ex-lance corporal, who's staying anonymous.

Alex van Straubenzee learned about his uncle's involvement in France through the project: "There are some harrowing stories, because Hitler ordered any member of what he called the terrorists - the SAS - to be killed out of hand, they were not to be taken prisoner."
