This is a remarkable story and one that will move many, even to tears. For more than twenty-five years, David Nott has taken unpaid leave from his job as a general and vascular surgeon with the NHS to volunteer in some of the world’s most dangerous war zones. From Sarajevo under siege in 1993, to clandestine hospitals in rebel-held eastern Aleppo, he has carried out life-saving operations and field surgery in the most challenging conditions, and with none of the resources of a major London teaching hospital. Driven both by compassion and passion, the desire to help others and also the thrill of extreme personal danger, he is now acknowledged to be the most experienced trauma surgeon in the world.

But slowly David began to realise that flying into a catastrophe – whether war or natural disaster – was not enough. Local doctors needed to learn how to treat the appalling injuries that war inflicts upon its victims. Since 2015, his foundation has trained other doctors in the art of saving lives threatened by bombs and bullets. War Doctor is his extraordinary story.
