Sassoon was a paradox as a human being. A sensitive and cultivated man and a world-famous poet when still in his twenties, he was also a ferocious fighter on the battlefield, dubbed "Mad Jack" by his men and a holder of the prestigious Military Cross. Disenchanted by the wastage and slaughter he had experienced, in 1917 he wrote a denunciation of the war and was promptly shut up in an asylum in Craiglockhart, Britain, where he composed many of the poems that appear in this book. Later he returned to the front and was shot in the head, but survived and enjoyed a prolific and diverse writing career, somewhat annoyed (as Hart-Davis tells us) that he had gone down in history as a "war poet." Reading this book, however, it is easy to see why.
