Question 1
2 marksFigure 1 is a timeline of the war at sea. Event A was the sinking of a British passenger liner by a German U-boat off the coast of Ireland, with the loss of about 1,200 lives. Event B was a change in German naval policy that led the USA to break off diplomatic relations with Germany.
Name the liner sunk in event A and describe the change in policy in event B.
Model answer
A was the sinking of the Lusitania (7 May 1915). B was Germany's decision to resume unrestricted submarine warfare from 1 February 1917, sinking any ship in the waters around Britain without warning, including neutral American ships.
Explanation
The Lusitania was sunk by U-20 off southern Ireland; about 1,200 people died, including 128 Americans, which turned American opinion against Germany. Germany limited its U-boat campaign after American protests, but in February 1917 it gambled on unrestricted warfare to starve Britain out; the USA broke off relations on 3 February and declared war on 6 April 1917.
