The German cargo submarine Deutschland docked in Baltimore. July 9, 1916
American ports were open to ships of all countries as the United States was a neutral nation. Germany's simply couldn't get to US ports in 1916.
Submarines could, and therefore the Germans actually constructed the Deutschland, a cargo submarine, which completed its first Atlantic crossing to the US on July 9, 1916. The crew was celebrated due to the novelty of its passage. It would make one additional crossing prior to the United States entering World War One. Amazingly, the submarine, even after being converted to a fighting vessel, survived the war.
