Central Otago-born Doug Jolly was one of the greatest war surgeons of the twentieth century. Tireless, dedicated and courageous, he was one of the most gifted Republican Army surgeons in the Spanish Civil War and his surgical manual based on his battlefield experiences close to the frontline was widely used in later wars. Frontline Surgeon traces Jolly's remarkable career from medical training in 1920s New Zealand to medical director of Britain's largest hospital for amputees, and restores him to the ranks of pioneers of modern medicine.
