What was the group of destroyers that escorted merchant ships across the Atlantic in groups?

The group of destroyers that escorted merchant ships across the Atlantic in groups during World War II was known as a "convoy." These convoys were protected by naval escorts, primarily destroyers, to defend against attacks from German U-boats and aircraft. The strategy was crucial in ensuring the safe passage of supplies and troops between North America and Europe. This coordinated effort helped mitigate losses and maintain vital supply lines.
