As Angus Calder states in his introduction to this edition, 'Seven Pillars of Wisdom is one of the major statements about the fighting experience of the First World War'. Lawrence's younger brothers, Frank and Will, had been killed on the Western Front in 1915. Seven Pillars of Wisdom, written between 1919 and 1926, tells of the vastly different campaign against the Turks in the Middle East - one which encompasses gross acts of cruelty and revenge and ends in a welter of stink and corpses in the disgusting 'hospital' in Damascus.
