128 innocent Americans lost their lives. President [[Woodrow Wilson]], saying America was too proud to fight, demanded promises that Germany would never again sink unarmed passenger liners. Germany so promised but a few weeks later sank another passenger ship, the [[Arabic attack|''Arabic'']] with more innocent Americans killed. Finally the Germans backed away from attacks on civilian ships. When they resumed unrestricted submarine warfare in early 1917 their goal was to defeat Britain quickly, knowing full well that Americans would go to war when American ships started going down, as happened in April 1917. | 128 innocent Americans lost their lives.
