THE INSPIRATION BEHIND THE BBC DRAMA THE CRIMSON FIELD''On the face of it,'' writes Lyn Macdonald, ''no one could have been less equipped for the job than these gently nurtured girls who walked straight out of Edwardian drawing rooms into the manifest horrors of the First World War ...'' Yet the volunteer nurses rose magnificently to the occasion. In leaking tents and draughty huts they fought another war, a war against agony and death, as men lay suffering from the pain of unimaginable wounds or diseases we can now cure almost instantly. It was here that young doctors frantically forged new medical techniques - of blood transfusion, dentistry, psychiatry and plastic surgery - in the attempt to save soldiers shattered in body or spirit. And it was here that women achieved a quiet but permanent revolution, by proving beyond question they could do anything. All this is superbly captured in The Roses of No Man''s Land, a panorama of hardship, disillusion and despair, yet also of endurance and supreme courage.''Lyn Macdonald writes splendidly and touchingly of the work of the nurses and doctors who fought their humanitarian battle on the Western Front'' Sunday TelegraphOver the past twenty years Lyn Macdonald has established a popular reputation as an author and historian of the First World War. Her books are based on the accounts of eyewitnesses and survivors, told in their own words, and cast a unique light on the First World War. Most are published by Penguin.
