Demobilised after the war, Smith returned to London. As a war hero, he was intermittently invited to social functions. In June 1920, he attended a garden party at Buckingham Palace, given by the king for all surviving Victoria Cross recipients. They included veterans of the Indian Mutiny, Rorke's Drift, Relief of General Gordon, the First and Second Boer Wars, countless campaigns on the borders of the empire, and dozens from the Great War. In October 1921, with Harry Kenny, he unveiled the Hackney War Memorial. In 1922, he attended "The Pilgrimage to Ypres", in Belgium, laying a wreath at the Cloth Hall there.
