Their name carries an aura of prestige and mystery - the British Army’s most renowned special forces unit - the best of the best. For this incredible episode, James spoke to author and filmmaker, Damien Lewis, about the story of the Special Air Service. They explore the birth of the unit, the selection of the brightest recruits, all day training in the North African desert with just one container of water. Next, we are taken through some of the unthinkable missions undertaken during the Second World War and Damien takes us in for a closer look at Operation Gain, when men were dropped behind enemy lines after D-Day. Damien and James discuss the consequences for SAS troops captured by the Nazis, and the SAS War Crimes Investigation Team - set up in May 1945 - which was responsible for bringing Nazis to justice and for the continuation of the SAS. Damien’s book, SAS Band of Brothers, is out now. This episode will have you on the edge of your seat.
