WW1 by sea: Germans

  • Germany launched the U-Boat campaign in the Atlantic to blockade British supplies

  • Germany declared a naval blockade to Britain

    Many ships arriving at Britain or going out from it were sunk by German U-boots. This violated the Prize Rules of the Hague Convention and turned neutral opinion against the Central Powers. It was one of reasons for Brazilian’s entrance in the war later.
  • A German torpedo attack sunk the RMS Lusitana

    This had a loss of 1,000 lives being 128 Americans. This was a factor in bringing the US into the war
  • Germany renewed unrestricted submarine attacks

    After scaling down U-boat attacks after the Lusitania, Germany renewed unrestricted submarine attacks in February 1917 in an attempt to starve Britain and France into surrender.
