U-boats had to surface to attack ships.
U-boats sank ships carrying civilians.
U-boat is a term that refers to military submarines operated by Germany during the First and Second World Wars. The primary targets of the u-boat campaigns were merchant convoys from the British Empire and the United States to the United Kingdom, the Soviet Union and the Allied territories in the Mediterranean.
However, u-boats occasionally attacked ships carrying civilians. One of the most renowed examples was that of the liner RMS Lusitania on May 7, 1915. The sinking claimed 1,198 lives, 128 of them American civilians.
"U-boats had to surface to attack ships"
could you provide the answer choices?
The answer is A. U-boat warfare was the German response to the British blockade.
As Germany had only limited access to the ocean and since it was primarily a land based empire, naturally they did not possess a strong navy. However, the British Royal navy was the largest and the most powerful navy at the time. Because of this, Royal navy was able to blockade the German ports and the ports of German allies and prevented them from resources and other supplies from the sea.
This is why the Germans developed underwater U boat warfare to defeat the royal navy and their blockades.
The correct answer to this open question is the following.
What is true about Germany's use of U-boats is that these boats sank ships that carried civilians during World War 1, such as the RMS Lusitania ship.
A German U-boat sank the RMS Lusitania transatlantic ship that transported civilians on May 7, 1915. Great Britain had declared the North Sea as a war zone in 1914 and prohibited all imports coming from Germany. Although the Germany embassy in the US published in the newspaper warnings to avoid navigation in the conflictive zone, the Lusitania navigated those waters and the tragedy occurred. This was one of the reasons that pushed President Woodrow Wilson into Worl War 1.
