The so-called “Great War” that ensued would be one of unprecedented destruction and loss of life, resulting in the deaths of some 20 million soldiers and civilians and the physical devastation of much of the European continent.
  • Battle of Masurian Lakes

    Having defeated the Russian Second army, the Germans turned their attention to the Russian First army at Masurian Lakes. Although the Germans were unable to defeat the army completely, over 100,000 Russians were taken prisoner.
  • Battle of Jutland

    German forces, confined to port by a British naval blockade, came out in the hope of splitting the British fleet and destroying it ship by ship. However, the British admiral, Beatty, aware that the German tactics were the same as those used by Nelson at Trafalgar, sent a smaller force to lure the German’s into the range of Admiral Jellicoe’s main fleet. Although Beatty’s idea worked, the exchange of fire was brief and the German’s withdrew.
