The Royal Naval Patrol Service (RNPS) was a branch of the Royal Navy active during both the First and Second World Wars. The RNPS operated many small auxiliary vessels such as naval trawlers for anti-submarine and minesweeping operations to protect coastal Britain and convoys.
The Royal Naval Patrol Service has its origins in the Great War when the threat of mine warfare was first realized by the British Admiralty. The pre-war Commander-in-Chief of the Home Fleet, Admiral Lord Charles Beresford, is credited with recommending the use of Grimsby trawlers for minesweeping operations following visits he made to various East Coast Ports in 1907. Grimsby, with its impressive docklands and trawler fleet was seen as ideal, with the Commander-in-Chief arguing that the fishing fleet would be inactive in times of war as fishing grounds became war zones. [1] It was also thought that trawlermen would be more skilled than naval ratings with regards to the handling of the sizeable warps and winches that would be required for mine sweeping as they were already accustomed to using them with the working of the trawl. The Admiralty Minesweeping Division remained active throughout the remainder of World War I until the end of the war when the trawlers were returned to their owners to resume fishing operations and the division was disbanded.
The need for a skilled minesweeping force was recognised to be a part of modern naval warfare and the Royal Navy later commissioned one flotilla of fleet minesweepers for the instruction of ratings and junior officers. Three trawlers were then added to the group along with the re-introduction of training in the Trawler Section of the Royal Naval Reserve and, under the new name of the Royal Naval Patrol Service courses in training began at Portland. As tensions mounted in the years before the Second World War training intensified for officers and ratings and experiments and developments in sweeping methods and equipment were carried out, including improvements made to the Oropesa Sweep, named after the trawler that first tried the method in 1918.
In the summer of 1939 the Admiralty purchased 67 trawlers with a further 20 newly constructed and at the outbreak of World War II every available minesweeper of the Royal Navy and Royal Naval Patrol Service was at her war station. [1] HMS Europa, usually known as Sparrow's Nest, became the Central Depot of the Royal Naval Patrol Service, located at Lowestoft, the most easterly point of Great Britain, and then the closest British military establishment to the enemy until decommissioned in 1946. The Lowestoft War Memorial Museum in the town is housed in the old Royal Naval Patrol Service headquarters building.
This eventually became the training and drafting base for more than 70,000 men, who manned 6,000 small craft of numerous types, including trawlers, whalers, drifters, MFVs (Motor Fishing Vessels), MLs (Motor Launches), and later MMS (Motor Minesweepers or "Mickey Mouses"), American produced BYMS (British Yard Mine Sweepers) and numerous requisitioned vessels. [2]
Grimsby once again proved its worth in service to minesweeping, becoming the largest minesweeper base in Britain, and making possible the clearing of 34,858 mines from vital sea lanes by the brave men of the sweepers. [3]
Between 1942 and its decommissioning in 1946 new construction ships and craft manned by the Service totalled 1,637 of various kinds including converted trawlers, corvettes, fuel carriers, motor launches and naval seaplane tenders. Of this total, from September 1939 through to May 1945, approximately 260 trawlers were lost in action... This material loss however pales into insignificance when compared to the 15,000 or so, RNPS personnel who were killed in the Second World War, including the 2385 RNPS seaman who "have no known grave but the sea". [4]
The advantages of using small ships for minesweeping and other duties had been recognised in the First World War and many of the crews of the peacetime fishing fleets had been encouraged to join the Royal Naval Reserve. Because the majority were Reservists the RNPS became a "Navy within a Navy". [2]
Because it used out-dated and poorly armed vessels, such as requisitioned trawlers crewed by ex-fishermen, the RNPS came to bear a number of unofficial titles that poked fun at it, such as "Harry Tate's Navy", "Churchill's pirates" and "Sparrows".
The name 'Harry Tates' dates back to the First World War and was used as jargon for anything clumsy and amateurish. It originated from an old music hall entertainer who would play the clumsy comic who couldn't get to grips with various contraptions. His act included a car that gradually fell apart around him. By the start of World War II it had been adopted by the Royal Navy and used for the purpose of poking fun at the trawlers and drifters of the Royal Naval Patrol Service. In true RNPS style they took it on the chin and the title of Harry Tate's Navy was proudly adopted. As the war went on it was to become a worthy password for courage. [5]
Because the peacetime crews became Naval seamen together they developed a special camaraderie. This camaraderie continued in the Service throughout World War II, even though by the end most RNPS members were "hostilities only" [6] who had had little connection with the sea before the war. [7]
The Royal Naval Patrol Service suffered over 250 lost vessels, more than any other branch of the Royal Navy [8] Because of the dangers and losses faced by the men of the Royal Naval Patrol service, they were honoured in a statement made by Churchill and by a unique silver badge, worn on the sleeve of the serviceman's uniform, that was awarded to those who served six months or more in the RNPS.
MESSAGE FROM THE PRIME MINISTER TO THE OFFICERS AND MEN OF THE MINESWEEPING FLOTILLAS
Now that Nazi Germany has been defeated I wish to send you all on behalf of His Majesty's Government a message of thanks and gratitude.
The work you do is hard and dangerous. You rarely get and never seek publicity; your only concern is to do your job, and you have done it nobly. You have sailed in many seas and all weathers... This work could not be done without loss, and we mourn all who have died and over 250 ships lost on duty.
No work has been more vital than yours; no work has been better done. The Ports were kept open and Britain breathed. The Nation is once again proud of you.
W S Churchill [9]
The RNPS fought in all theatres of the war, from the Arctic to the Mediterranean, from the Atlantic to the Far East, involved in convoy duty, minesweeping and anti-submarine work. Most particularly they kept the British coast clear of the mines that were wreaking havoc with merchant ships. [2]
One RNPS member, Lieutenant Richard Stannard won the Victoria Cross while in command of the Hull trawler Arab in the Namsos campaign.
The fighting fleet of the RNPS consisted of a range of vessels. In the days prior to World War II the Grimsby class sloop was used in mine sweeping and anti-submarine operations. [10] This class is named after the port that was first recommended for use in minesweeping with its trawler fleet in 1907 by Commander-in-Chief of the Home Fleet Admiral Lord Beresford. [11] In 1933 four of the new Halcyon-class minesweepers were laid down, regarded as 'fast sweepers'. [12] They were 20 ft shorter than the Grimsby Class as the need for small vessels of shallow draught was recognised as crucial for working in minefields. [13] By 1939, with the threat of war imminent, the more economically and rapidly built 'whale catcher' Flower-class corvettes were built.
With war now a certainty, the Admiralty expanded minesweeping fleets by purchasing 67 trawlers and ordering a further 20 trawlers to be purpose built, [14] recognising their ideal suitability for sweeping. Hundreds more vessels would be requisitioned by the Admiralty as the war continued and more purpose built vessels were developed, including specially designed timber-hulled Motor MineSweepers (MMS class) that would be better protected from the threat of magnetic mines. [15]
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping.
The Ton class were coastal minesweepers built in the 1950s for the Royal Navy, but also used by other navies such as the South African Navy and the Royal Australian Navy. They were intended to meet the threat of seabed mines laid in shallow coastal waters, rivers, ports and harbours, a task for which the existing ocean-going minesweepers of the Algerine class were not suited.
The River class was a class of minesweeper built for the British Royal Navy in the 1980s, designated Fleet Minesweepers (MSF). Operated mainly by the Royal Naval Reserve they were taken out of service in 1990s and sold to foreign navies.
USS Auk (AM-57) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.
USS Velocity (AM-128) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing. She was the second warship to bear the name.
The Castle-class minesweeper was a highly seaworthy naval trawler adapted for patrol, anti-submarine warfare and minesweeping duties and built to Admiralty specifications. Altogether 197 were built in the United Kingdom between 1916 and 1919, with others built in Canada, India and later New Zealand. Many saw service in the Second World War.
A danlayer was a type of vessel assigned to minesweeping flotillas during and immediately after World War II. They were usually small trawlers, fitted for the purpose of laying dans. A dan is a marker buoy which consists of a long pole moored to the seabed and fitted to float vertically, usually with a coded flag at the top.
Commissioned minesweepers and danlayers of the Royal New Zealand Navy (RNZN) from its formation on 1 October 1941 to the present. The RNZN was created two years into World War II. For coherence this article covers the war years from the start, and thus includes also the New Zealand minesweepers operating from the beginning of the war.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some, known in the Royal Navy as "Admiralty trawlers", were purpose-built to naval specifications; others were adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
Naval trawlers were purpose-built or requisitioned and operated by the Royal Navy (RN), mainly during World Wars I and II. Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler".
The German Mine Sweeping Administration (GMSA) (‹See Tfd›German: Deutscher Minenräumdienst) was an organisation formed by the Allies from former crews and vessels of the Nazi Germany's Kriegsmarine for the purpose of mine sweeping after the Second World War, predominantly in the North Sea and Baltic Sea, which existed from June 1945 to January 1948.
HMT Almond was a Tree-class naval trawler of the British Royal Navy. Almond was launched in 1940 and served in World War II, being sunk by a mine on 2 February 1941.
HMCS Canso was a Bangor-class minesweeper initially constructed for the Royal Navy during the Second World War. Transferred to the Royal Canadian Navy in 1942, the minesweeper saw service on both the West and East Coasts of Canada as a convoy escort and patrol vessel. The vessel participated in the invasion of Normandy and spent the final years of the war in European waters. Canso was returned to the Royal Navy following the war and was broken up for scrap in 1948.
HMCS Mulgrave was a Bangor-class minesweeper that served with the Royal Canadian Navy during the Second World War. Entering service in 1942, the minesweeper took part in the Battle of the Atlantic and the invasion of Normandy. While sweeping for naval mines off France in 1944, the vessel hit one. The ship was towed back to port where Mulgrave was declared a constructive total loss. Laid up until the end of the war, the minesweeper was broken up in 1947.
The Llewellyn-class minesweepers were a series of ten coastal minesweepers constructed for the Royal Canadian Navy during the Second World War. Based on the Admiralty type MMS-class minesweeper, the Llewellyn class were constructed of wood and used for the removal of magnetic influence mines. Two were built in Quebec, with the eight constructed on the Western Coast of Canada. Mostly used as guard ships during the war, only three of the ten remained in Royal Canadian Navy service following the war, with the last being discarded in 1957. Following naval service, vessels of the class ended up in commercial service, with some becoming fishing vessels, cargo ships and one a floating restaurant. Six of the ten ships were lost in commercial service.
USS Richard Bulkeley was a minesweeping trawler leased from the British Royal Navy. Built as HMT Richard Bulkeley, the ship was a Mersey class trawler, purpose-built for service with the Auxiliary Patrol. On 12 July 1919, it was sunk by a mine while removing minefields in the North Sea.
HMS Europa was a Royal Navy Shore establishment active between 1939 and 1946 during World War II as the central depot for the Royal Naval Patrol Service (RNPS). It was established after the commandeering of Sparrows Nest Gardens, a private residence in Lowestoft in Suffolk. Originally named Pembroke X, the base was the headquarters of the RNPS, responsible for protecting coastal Britain and its convoys, in particular undertaking minesweeping duties. Over 70,000 men and 6,000 vessels, many of them small civilian vessels such as armed trawlers, served in the RNPS during the war.
Junella was a fishing trawler, best known for her service with the Royal Navy during the Falklands War. She was built in 1975 for J Marr & Son, a Hull-based fishing company. On 11 April 1982 she was taken up from trade by the British government and commissioned into the Royal Navy. She was fitted with Second World War era minesweeping gear at Rosyth Dockyard, manned by Royal Navy sailors and allocated to the 11th Mine Countermeasures Squadron. She sailed on 26 April but was unable to commence sweeping until after the 14 June Argentine surrender. In the meantime she was utilised to transfer troops and stores between ships and landed special forces troops at San Carlos. Demining operations commenced on 21 June. Junella returned to the United Kingdom on 11 August, carrying a defused Argentine mine.
HMS Rosemary was an Arabis-class minesweeping sloop of the British Royal Navy. Built by the Teesside shipbuilder Richardson, Duck and Company from 1915–1916, Rosemary carried out minesweeping and anti submarine operations during the First World War. She was used for fishery protection duties during the 1930s, and served through the Second World War, finally being sold for scrap in 1947.
