George, and subsequently became the subject of a dispute among Sassoon's heirs. At Craiglockhart, Sassoon met Wilfred Owen, another poet. It was thanks to Sassoon that Owen persevered in his ambition to write better poetry. A manuscript copy of Owen's Anthem for Doomed Youth containing Sassoon's handwritten amendments survives as testimony to the extent of his influence and is currently on display at London's Imperial War Museum. Sassoon became to Owen "Keats and Christ and Elijah", according to a surviving letter which demonstrates the depth of Owen's love and admiration for him. Both men returned to active service in France, but Owen was killed in 1918, a week before Armistice. Sassoon was promoted to lieutenant, and, having spent some time out of danger in Palestine, eventually returned to the Front. On 13 July 1918, Sassoon was wounded again—by friendly fire when he was shot in the head by a fellow British soldier who had mistaken him for a German near Arras, France. As a result, he spent the remainder of the war in Britain. By this time he had been promoted to acting captain. He relinquished his commission on health grounds on 12 March 1919, but was allowed to retain the rank of captain. After the war, Sassoon was instrumental in bringing Owen's work to the attention of a wider audience. Their relationship is the subject of Stephen MacDonald's play, Not About Heroes.

In November 1918, he travelled to Blackburn to support the Labour candidate in the general election, Philip Snowden, who had been a pacifist during the war. Though a self-confessed political novice, Sassoon delivered campaign speeches for Snowden, later writing that he ‘felt grateful for [Snowden's] anti-war attitude in parliament, and had been angered by the abuse thrown at him. All my political sympathies were with him.’ While his commitment to politics waned after this, he remained a supporter of the Labour Party, and in 1929 ‘rejoiced that [they] had gained seats in the British general election.’ Similarly, ‘news of the massive Labour victory in 1945 pleased him, because many Tories from the class he had loathed during the First World War had gone.’ In 1919 took up a post as literary editor of the socialist
