right after deutschland got back, the second of these merchant u-boats sailed. it was the bremen. never arrived in the united states. it is still missing today. the deutschland made a second trip later in 1916. put into new london, connecticut. less publicity. and new of u-boats, this is you 53. standard production german submarine. it sailed in september, 1916. for the port of newport, rhode island. october 7, it put into port. to u.s. naval officers there. it did not refuel. day, it went out, and sank five merchant ships. stopped them and scuttled them. there was no loss of life. there was like 15 u.s. destroyers running around trying to keep ships from being sunk. but, because the germans were operating in accordance with international law, these ships, dutch, norwegian, were carrying were surprised for britain, was a perfectly legally justifiable action. by the submarines. this sent a rather not very subtle message, obviously, if germany enters the war, you know, u.s. enters the war, two countries are at war, what is going to happen?? u-boats can come over here and sink ships.
