therefore brought this strong nation into the war. This caused Germany to prevent the entrance of natural ships such as those of America. The sinking of ‘Lusitania’ outraged the Americans and changed Germanys ways of sinking ships by submarine.
In 1915, the use of concealed guns on the ships ordered the sinking of natural or unnatural ships without warning. The submarine warfare became too dangerous and Germany feared America’s entrance into the war. Germany as it is, lacked submarines to guard the territory around the British coastline. But this didn’t stop Hollweg. He felt that armed and unarmed ships should be sunken with no warning inside the war zone. As the argument of unrestricted submarine warfare continued, it was agreed that this would better Germanys position. Finally our decision for unrestricted submarine warfare came to effect on February 1, 1917. Shortly after, on April 6, 1917, America officially entered the war.
