The answer is: Warships traveled with merchant ships for protection.
Explanation:
During World War I, the <em>Germans</em> waged <u>unrestricted submarine warfare</u> in its <u>war-zone waters.</u> This restricted ships and carriers for passengers to pass through. As a remedy, the Allies were protected against the German submarines through "convoy." This allowed the merchant vessels to travel protected in the sea together with<em> long-endurance warship</em>s or<em> destroyers</em> and other<em> patrol vessels.</em> They could also travel in large groups across the Atlantic.
Originally speaking, convoys were used to protect the merchant ships from<u> pirates.</u> However, the strategy was also effective enough in protecting the merchant ships against the German submarine warfare.
Thus, this explains the answer.
