In the world of military history there is no brand as potent as that of the SAS. They burst into global prominence in 1980 with their spectacular storming of the Iranian Embassy, and there have been hundreds of books, films, documentaries and even reality TV shows about them.

Gavin Mortimer is a writer, historian and television consultant whose ground-breaking book 'Stirling's Men' remains the definitive history of the wartime SAS. Drawing on interviews with more than sixty veterans, most of whom had never spoken publicly, the book was the first comprehensive account of the SAS brigade. He has also written histories of the SBS, Merrill's Marauders and LRDG, again drawing heavily on veteran interviews. Gavin was the historical consultant on the 2017 BBC documentary about the wartime SAS and he has guided several serving members of the SAS around the sites in France where their predecessors operated in the summer of 1944.
