A Military Atlas of the First World War Quotes

“sea, 1916 was the year of Jutland (pages 256–261), of intensified measures by the British to blockade Germany, and of a fifty per cent increase over the 1915 figures for the tonnage of Allied shipping sunk by U-boats. The outlook for 1917 was ominous.”
― Arthur S. Banks, A Military Atlas of the First World War
