Your teacher is probably referring to the "Convoy System" that was developed by the British Royal Navy & used by the Allies. It meant that merchant ships with the same cruising speeds traveled together in a group or "convoy". The group may be escorted by Navy warships that were capable of protecting the merchants from German U-boats, Q-ships, or surface raiders. Ships that were very slow, or fast would not travel in a convoy.
Neutrality Patrols
We entered World War 1 because of a German submarine attack on U.S. merchant ships in 1917.
Primarily over 2,000 merchant vessels, with a sprinkling of allied warships.
The Merchant Marine naval ships provided the transport of supplies .
Early in the war, merchant ships carrying supplies to both Russia and Britain were targeted heavily by German U-Boats(submarines). Since there were not enough destroyers and destroyer escorts to protect each individual ship, convoys were formed. In these convoys, merchant ships were grouped together and protected by a small number of escort vessels
103 merchant ships were sunk in world war one
