The Q-Ship, or Decoy Ship has been a tactic of maritime warfare since earliest times. Put simply, it involves a ship flying the flag of a neutral or ally, with perhaps a false name and hidden armaments. This fools an attacker or target until it is too late, and the element of surprise is of great advantage to the 'victim' turned attacker.
These 'Trojan Horses' of maritime warfare were used by nations such as Britain France Holland and Spain since the 16th Century in an informal way. It was not until World War One that they were organised on a command scale. Winston Churchill, First Lord of the Admiralty, was credited with the organisation of the Royal Navy Q-Ships.
Haulbowline Dockyard, in Cork Harbour was responsible for the conversion of many mercantile steamers to armed decoy ships. The majority however appear to have been converted in larger navy yards such as Devonport.
Some Q-ships were not converted merchant vessels, but a type of naval ship called a sloop. These were single-screw naval patrol craft, but some classes had the passing appearance of a merchant ship.
The effectiveness of the Q-ship was greatest in 1916, but in the latter years of the war they became common knowledge among combatants, with the enemy treating any innocent ship with great suspicion. It could be argued that they contributed in some way to the casualties amongst merchant seamen as attacks without warning became the norm.
At the beginning of WW1 Prize Rules -a system of stop and search had been generally observed with merchant ships. As the War progressed there were the Q-Ships, a policy of deliberate ramming , and the arming of merchant ships (DAMs), to contend with. Submarine commanders were more likely to take the tactic of the unobserved torpedo attack, or shelling from a long distance, with less chance for the ships crew to take to the boats.
Aug 21 1917 Commander Wortman of the American Destroyer USS Porter , based in Queenstown, stated at the end of a confidential report -
"The impression prevails that Q Boats have rather outlived their usefulness - the enemy are on to them "
The reputation of the Q-Ships, and the heroism of their crews, was tarnished by the actions of the Q-Ship Baralong , with accusations of the slaughter of unarmed u-boat sailors
The effectiveness of the Q-Ship during WW1 is a matter of some debate. There were 14 submarines credited as destroyed, but at a loss of 27 Q-ships, some with their entire compliments of highly trained crew.
Q-Ships were tried on a limited scale in World War Two, but were quickly disbanded.
The WW1 Q-Ships of the Royal Navy were organised by their commands and fought in almost all theatres of war. The commands were:
Vice-Admiral Commanding. Queenstown.
Commodore in Charge. Falmouth
Vice-Admiral. Milford Haven
Vice-Admiral Commanding. Orkneys and Shetland
Commander in Chief, Rosyth.
Senior Naval Officer. Granton
Rear-Admiral East Coast
Senior Naval Officer. Malta
Vice Admiral Commanding. Eastern Mediterranean
Rear Admiral. QCS

Wrecks over 100 years old and archaeological objects found underwater are protected under the National Monuments (Amendment) Acts 1987 and 1994. Significant wrecks less than 100 years old can be designated by Underwater Heritage Order (UHO) on account of their historical, archaeological or artistic importance as is the case with the wreck of the RMS Lusitania lost off the Old Head of Kinsale in 1915. UHOs can also be used to designate areas of seabed or land covered by water to more clearly define and protect wreck sites and archaeological objects. Under the legislation all diving on known protected wreck sites or with the intention of searching for underwater cultural heritage is subject to licensing requirements. https://www.archaeology.ie/underwater-archaeology
