German Blockade Runner Submarines-- Part 2: The Bremen Not So Lucky and the U-53

The Deutschland's sister submarine, the Bremen, was less fortunate and disappeared on its maiden voyage.

A less favorable impression was left by the U-53.  After refueling at Newport, Rhode Island,, Rose raided Allied shipping off the coast of Canada and the United States.  Although this was in international waters and the law was followed closely by the Germans, it was seen as an affront to the U.S., particularly when  U.S. warships were forced to stand aside while merchant ships nearby were sunk.
