In the meantime, two months had elapsed from the time when the German ambassador, Count Von Bernstorff, had been sent home by the United States. The Germans, true to their word, had begun their campaign of attacking and sinking without warning ships of all kinds in the waters surrounding Great Britain and France. Even the hospital ships, marked plainly with the red cross, and boats carrying food to the starving people of Belgium, were torpedoed without mercy. The curious state of public feeling in Germany is well illustrated by an incident which happened at this time. It so happened that an English hospital ship, crossing the channel, was laden with about as many German wounded as British. These men had been left helpless on the field of battle after the Germans had retreated, and had been picked up and cared for by the British, along with their own troops. A German submarine with its deadly torpedo sent this vessel to the bottom. The wounded men, German and British alike, sank without the slightest chance for their lives. A burst of indignation came from all over Germany against the “unspeakable brutality” of the British who dared to expose German wounded men to the danger of travel on the open sea! The British were warned that if this happened again the Germans would make reprisals upon British prisoners in their hands. [Illustration: Flight from a Torpedoed Ocean Liner]
