Hammond's map of Europe shades the \"Barred Zones\" in which Germany declared from February 1917 that shipping would be sunk without warning: the whole Atlantic approach to the British Isles and France, the Mediterranean from Spain to the Aegean, and the Arctic approach to Archangel. Two gaps tell the story of neutral rights — a \"Safety Lane to Falmouth for one American ship per week\" and a \"Safety Lane to Greek Territorial Waters\". Unrestricted submarine warfare brought America into the war, and the red Armistice Line of 11 November 1918 closes the account.
