They ordered their U-boats (Submarines) to attack all kinds of vessels that passes through the areas.

No matter if are they British boats or someone else’s.

German authority’s main purpose through the policy was to make the British government oblige to surrender the war.

On the 7th of May 1915, the German navy attacked and sank a British vessel ‘Lusitania’, where more than 1070 Britishers and 128 Americans lost their lives.

They kept attacking other merchant vessels also, where the majority were from the United States of America. 

This act of the German navy made America quite angry. 

Hence, at that time, the US president, Woodrow Wilson strongly warned Germany to stop attacking unarmed vessels without any warning.

In September 1915, Germany had to stop the policy due to pressure from the US and other neutral countries.
