In the early 20th century a number of Trinity House lightships around the coast were manned with wireless telegraphy sets and operators on board. These ships were in contact with local coastguard stations and their main role was to guide shipping into safe harbour and act as a lookout for ships in distress. Although Trinity House was impartial during the First World War it is possible they (or staff on military attachment) were involved in some war work. The lightships with wireless telegraph sets are included on the First World War admiralty list of home wireless stations in National Archives file ADM137.4680. (2)
