1. The German U-Boat campaign aimed to cut off supplies to Britain and was part of a broader strategy to starve the British into submission.
2. The introduction of unrestricted submarine warfare in early 1917 marked a significant escalation in U-Boat attacks, directly leading to increased tensions with neutral countries like the United States.
3. U-Boats were often equipped with torpedoes and could travel underwater for extended periods, allowing them to launch surprise attacks on unsuspecting ships.
4. The Allies responded to U-Boat threats by developing convoy systems, where merchant ships would travel in groups escorted by warships for protection against submarine attacks.
5. The effectiveness of U-Boats declined later in the war due to advancements in anti-submarine warfare technologies, including depth charges and sonar detection methods.

Review Questions

• How did German U-Boats impact Allied shipping and the overall naval strategy during World War I?
  • German U-Boats significantly disrupted Allied shipping by targeting merchant vessels, leading to widespread losses and creating shortages of supplies. This tactic forced the Allies to adapt their naval strategies, including the implementation of convoy systems for protection against submarine attacks. The threat posed by U-Boats contributed to increasing tensions between Germany and neutral nations, particularly the United States, which ultimately influenced America's decision to enter the war.
• Evaluate the consequences of unrestricted submarine warfare initiated by Germany in 1917 on its relationship with neutral countries, particularly the United States.
  • The introduction of unrestricted submarine warfare in 1917 had severe repercussions for Germany's relationship with neutral countries. This aggressive policy led to incidents like the sinking of the Lusitania, which resulted in significant civilian casualties and heightened anti-German sentiment. The continuous targeting of neutral ships pushed the United States closer to war as American public opinion turned against Germany, ultimately contributing to the American entry into World War I.
• Analyze how advancements in anti-submarine warfare technology affected the effectiveness of German U-Boats toward the end of World War I.
  • As World War I progressed, advancements in anti-submarine warfare technology significantly diminished the effectiveness of German U-Boats. The Allies developed new tactics such as convoy systems and improved weaponry like depth charges and sonar detection. These innovations allowed Allied forces to better protect merchant ships and detect U-Boats before they could launch successful attacks. The growing effectiveness of these countermeasures contributed to a decline in U-Boat success rates, limiting their impact on Allied shipping as the war came to a close.
