In August 1914 war broke out in Europe. Russia, France , Serbia, Belgium, and Great Britain were the Allies. On the other hand Germany, and Austria Hungary were called the central powers. During this world war many battles took place on land, but they also took place at sea. Germany had new weapons at the time called the U-boats, which was an underwater submarine that was able to sneak up on the enemy without being seen. So one year into war on May 1915 a German U-boat sank the British luxury ocean liner called the Lusitania. This killed 1,198 people and 128 americans lost their lives. This caused much debate in whether Germany was justified or not. Though there is scant information on how Germany was justified in sinking the Lusitania.
