Captain Von Spiegals and Zimmerman Telegram

The Captain Von Spiegals and the Zimmerman Telegram were talking about the U-Boat warfare in German point of view. Von Spiegals was the Captain of the U-Boat, and he had posted his memoirs in 1919. It was all about what happened during the U-Boat warfare and what the Captain Von Spiegals thought. It said things about "FIRE" the order he gave. On the other hands, the Zimmerman Telegram was written by Arthur Zimmerman. It was talking about the submarine that Germany was going to send on February and said they should keep the United States neutral.
