Other forms: convoys
A convoy is a group of vehicles or ships travelling under protection. An aid convoy, sail in convoy, a military convoy.
The Atlantic convoys of the Second World War proved the principle: ships sailing together were far safer than the same ships sailing alone, because an escort protects the whole group at once and a wide ocean is mostly empty. Note the same root as convey.
