24 mayo 1917 año - British Convoy System Established

Descripción:

The British Royal Navy introduces a newly created convoy system, whereby all merchant ships crossing the Atlantic Ocean would travel in groups under the protection of the British navy. A convoy of 10 to 50 merchant ships—along with, possibly, a troopship carrying arms and soldiers—might be escorted by a cruiser, six destroyers, 11 armed trawlers and a pair of torpedo boats with aerial reconnaissance equipment that could detect the movement of underwater submarines.
