Ex-Coldstream Guard, Mark Evans tells, for the first time, the incredible story of the Battle of Nad Ali in the Afghanistan conflict. On a patrol, Mark and his men are pinned down in a fire fight. Mark calls in air support but the Apache pilot makes a fatal error and opens fire on the British and ANA forces. Mark is one of the few to escape unscathed. Nad Ali is declared a 'black' zone with the RAF refusing to fly in and leaving Mark and his men without critical resources. Drawing on parallels with the famous battle of Rorke's Drift, that inspired the film Zulu, Code Black is a forthright account of modern warfare and the damaging effects of PTSD. Code Black reveals what it is like to fight on the front line and the challenges it presents to those it affects, not just as as soldiers, but as people.
