What was a result of the introduction of U boats by Germany?

• A. Increased naval battles
• B. Naval blockades of enemy ports
• C. Disruption of allied shipping
• D. Decline in submarine warfare

Answer: (C)

The introduction of U-boats (submarines) by Germany during World War I significantly disrupted Allied shipping, which is why this choice is correct. The German navy aimed to cut off supplies to the Allies by targeting merchant vessels in the Atlantic Ocean, leading to a considerable impact on the transportation of goods, military supplies, and resources essential for sustaining the war effort of Allied nations. This strategy was a key component of Germany's naval warfare and aimed to weaken the Allies by choking off supplies and cutting communication lines.

The effectiveness of U-boats led to heightened fear among shipping companies and prompted changes in naval strategy and shipping routes. The significant loss of merchant vessels to U-boat attacks was a major factor in the eventual shift of public opinion in some countries towards supporting military intervention in the war.

While increased naval battles and naval blockades of enemy ports did occur during this period, the defining characteristic of Germany's use of U-boats was the indiscriminate targeting of vessels, causing widespread disruption. The option reflecting a decline in submarine warfare does not apply, as U-boat usage expanded during the war, particularly in response to the Allied naval blockade of Germany.
