Lecture at the event 'Wilfred Owen: From Doomed Youth to the Battle of the Sambre'. Imperial War Museum, 10th November 2012. In this talk, Jean Moorcroft Wilson, presents Owen's full flowering as a late one. Fertilized by his meeting with Sassoon at Craiglockhart War Hospital for Neurasthenic Officers in August 1917 and nurtured by his own experiences of the 'pity of war', it died with Owen himself in one of the last Allied engagements in November 1917, the Battle of the Sambre.
