The brutal nature of the First World War presented frontline medical personnel with an array of horrific and debilitating wounds, inflicted on a previously unimaginable scale. From gas attacks and bayonet wounds to rifle fire and artillery barrages, day-to-day life on the frontlines posed a serious risk to life and limb. The doctors and nurses responsible for medical care rose to the challenge, and the First World War saw a dramatic transformation in the provision of frontline medicine. Many more lives would be saved than lost due to the efforts of these 'lifesavers'. Focusing on the Canadian experience, Tim Cook, author of Lifesavers and Body Snatchers, explains just how important and innovative the work of frontline medical staff was, and reveals the more sinister side of how these advances were achieved.
