Although a young doctor when he volunteered for the Spanish Civil War in late 1936, New Zealander Douglas Jolly swiftly acquired a reputation as one of the most gifted and energetic surgeons of the Republican Army’s medical services. Over the next two years he performed countless life-saving operations on wounded combatants from both sides of the conflict, as well as on civilians. Tireless, dedicated, and courageous, he developed significant and innovative treatment systems based on the principle of working as near as possible to the front line. Jolly used this unprecedented battlefield experience to write a manual that was widely used in World War II and the Korean and Vietnam Wars. Frontline Surgeon traces Jolly’s remarkable career from medical training in 1920s New Zealand, postgraduate study during the rise of fascism in Europe, almost a decade of frontline surgery, and into civilian life as medical director of Britain’s largest hospital for amputees. One of the greatest war surgeons of the twentieth century, Jolly has been mysteriously omitted from the ranks of pioneers of modern medicine. This engaging biography, intensively researched in many countries, both explains and redresses that omission.
