The young woman who made her name with Testament of Youth had by 1939 become an internationally respected writer. By producing her Letters to Peace Lovers throughout World War II she put her reputation on the line, with her opposition to saturation bombing and her concern about the sterility of some of the Government's war aims, including that of unconditional surrender. She wrote and sent her letters to a long list of subscribers, many of them servicemen, advocating the preservation of those humanitarian values that so easily become twisted in wartime, and giving a different perspective to momentous events such as Dunkirk, the German invasion of Russia, the dropping of the atomic bomb on Hiroshima and Nagasaki.
