The laws of nations, as observed by civilized countries in wars up to this time, have said that a blockade, in order to be recognized by all nations, had to be successful in doing the work for which it was intended. If England really was able to stop every boat sailing for German shores, then all nations would have to admit that Germany was blockaded; but if the Germans were able to sink only one ship out of every hundred that sailed into English ports, Germany could hardly be said to be carrying on a real blockade of England. In spite of protests from neutral nations who were peaceably trying to trade with all the countries at war, this sinking of merchantmen by submarines went on. In May, 1915, the great steamship _Lusitania_ was due to sail from New York for England. A few days before her departure notices signed by the German ambassador were put into New York papers, warning people that Germany would not be responsible for what happened to them if they took passage on this boat. Very few people paid any attention to these warnings. With over a thousand persons on board the _Lusitania_ sailed, on schedule time. Suddenly the civilized world was horrified to hear that a German submarine, without giving the slightest warning, had sent two torpedoes crashing through the hull of the great steamer, sending her to the bottom in short order. A few had time to get into the boats, but over eight hundred men, women, and children were drowned, of whom over one hundred were American citizens. Strange as it may seem, this action caused a thrill of joy throughout Germany. Some of the Germans were horrified, as were people in neutral countries, but on the whole the action of the German navy was approved by the voice of the German people. With a curiously warped sense of right and wrong the Germans proclaimed that the English and Americans were brutal in allowing women and children to go on this boat when they had been warned that the boat was going to be sunk! They spoke of this much in the manner in which one would speak of the cruelty of a man who would drive innocent children and women to march in front of armies in order to protect the troops from the fire of their enemies.
