"A 13-year project to document and commemorate every member of the SAS killed in the Second World War has for the first time confirmed identities of 13 lost members of the secretive, elite unit.

The 800-page roll of honour for the SAS and its forerunner, the Long Range Desert Group (LRDG), contains the stories of 374 men who died during the conflict, some of whose stories were on the verge of being lost.

The three-volume memorial published for this month?s 75th anniversary of the SAS's founding has been complied from an exhaustive trawl of service records, operational reports, medal citations, diaries and letters from next of kin."
