The system you are referring to is the Convoy System. In this system, cargo ships traveled together in groups, typically escorted by navy warships for protection against enemy attacks during times of war. This system was commonly used during World War I and World War II to safeguard merchant ships from submarines and other threats.

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.

In World War I, the "convoy system" was an organizational innovation by the western allies (in particular, the British) in response to German submarine attacks. In 1916 then even further in 1917, Great Britain organized all of its shipping into large groups called "convoys". Convoys traveled as one and were protected by dedicated warships throughout their journeys to and from ports in Great Britain. The convoy system succeeded in breaking the German submarine blockade.
