A 'convoy' is a group of
vehicles (of any type, but usually motor vehicles or ships) traveling together for mutual support. Often, a convoy is organized with armed defensive support, though it may also be used in a non-military sense, for example when driving through remote areas. If one vehicle breaks down or gets stuck, the other vehicle can assist with repairs or attempt to free the bogged-down vehicle. If repairs are not possible, the people from the broken-down vehicle can transfer to others.
Naval convoys
Age of Sail
By the
French Revolutionary Wars of the late
18th century, effective
naval convoy
tactics had been developed to ward off
pirates and
privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the
Spanish treasure fleets, that sailed from the 1520s until 1790.
When merchant ships sailed independently, a privateer could cruise a shipping lane and capture ships as they passed. Ships sailing in convoy presented a much smaller target: a convoy was no more likely to be found than a single ship. Even if the privateer found a convoy and the wind was favourable for an attack, it could hope to capture only a handful of ships before the rest managed to escape, and a small escort of warships could easily thwart it.
Many
naval battles in the
age of sail were fought around convoys, including:
★ The
Battle of Portland (
1653)
★ The
