The First World War ended for practical purposes with the Armistice of 11 November 1918, but the state of war between the belligerents came to an end only after the signing of the Treaty of Versailles on 28 June 1919. Following that Treaty the heralds were dispatched to proclaim the Peace, and this was done on 2 July 1919 from St James's Palace and other key points in London. This article by Oswald Barron, later Maltravers Herald Extraordinary, is from the July 1919 issue of Country Life. It shows Sir Henry Farnham Burke, Garter King of Arms, and Gordon Ambrose Lee, York Herald, making the Proclamation. College of Arms reference: Acc 2010/2.
