The Northern Patrol, also known as Cruiser Force B and the Northern Patrol Force, was an operation of the British Royal Navy during the First World War and Second World War. The Patrol was part of the British "distant" blockade of Germany. Its main task was to prevent trade to and from Germany by checking merchant ships and their cargoes. It was also to stop German warships, raiders and other German naval ships from leaving the North Sea for the Atlantic Ocean or entering the North Sea from the Atlantic, protect Shetland against invasion and to gather intelligence from intercepted neutral ships.[1]
The Northern Patrol operated under the command of the Grand Fleet during the First World War. At first, Edgar-class cruisers were used but these were not built for the seas around Scotland in winter and were replaced by civilian ships pressed into service as Armed Merchant Cruisers.
In the Second World War the Northern Patrol was commanded by the Home Fleet. Perhaps the Northern Patrol's most famous action was the loss of the armed merchant cruiser HMSRawalpindi on 23 November 1939. Captain Edward Kennedy RN, commander of Rawalpindi decided to fight the 11-inch gun German battleshipsScharnhorst and Gneisenau. The crew of Rawalpindi managed to inflict splinter damage on Scharnhorst during a short engagement before being sunk, only a few survivors being rescued by the Germans.[2]
For much of the nineteenth century, the Admiralty and much of the navy took it that the main aim was to engage and defeat an opposing fleet. In 1908 war orders to the Channel Fleet were that
The principal object is to bring the main German fleet to decisive action and all other operations are subsidiary to this end.
Success in this object would guarantee command of the English Channel and the North Sea, secure British trade and territory and allow the Expeditionary Force to reach France. The Admiralty expected that the German fleet would sally forth, soon after the declaration of war, to contest British command of the sea. An alternative to decisive battle was the close blockade of opposing ports as had been done during the Napoleonic Wars (1803–1815). Swift-sailing frigates cruised off French ports, backed by bigger ships out to sea. The blockading ships were almost immune to attack and had no need to return to port to refuel. The advent of steam power required more frequent returns to port for coal and after 1900, the risks to blockading ships multiplied with the advent of mines, torpedoes, submarines and long-range coastal artillery. By 1912, airships and aircraft could uncover the position of the bigger ships off shore and direct submarines and destroyers towards them. During the Russo-Japanese War (1904–1905), the Japanese fleet conducting the last close blockade, of Port Arthur, had suffered many losses from mines.[4]

The Navy policy for blockade evolved, in 1908 the commander of the Channel Fleet ordered that the big ships would move to positions beyond the range at which German destroyers could not reach if sailing at nightfall with orders to return the next morning, reckoned to be 170nmi (200mi; 310km). British ships in the Heligoland Bight should try to cut off German ships sailing from the Elbe or Jade or report the sailing of the High Seas Fleet (Hochseeflotte). The Admiralty had a change of heart in 1911 but by 1912 the war orders stipulated that a close blockade was superseded by an observational blockade formed by cruisers and destroyers ranged from the south-west coast of Norway, to half-way between Germany and England, level with Newcastle, then south to Texel, with the Battle Fleet cruising to the west of the line.[5]
Plans from 1905 to capture a German North Sea island as a forward base were also abandoned after the Germans fortified Heligoland and the Frisian Islands. The Grand Fleet war plans of June 1914 scrapped the observational blockade for the Grand Fleet to be based in Scotland, except for the Channel Fleet, which would remain on the south coast. The bases of the Grand Fleet were to block the northern exists of the North Sea and the Channel Fleet to seal the channel. The northerly line would stretch from the Scottish coast and northern islands to Norway, with the Grand Fleet based at Scapa Flow in Orkney, with un-armoured cruisers (later named the Northern Patrol) keeping watch on a line from the Shetlands to the Norwegian coast. The German navy was ignorant of the new policy and expected to find plenty of opportunities to whittle away the numerical superiority of the British.[6]
In a naval war with Germany, Britain had the great geographical advantage of obstructing German access to the Atlantic Ocean. Should German ships seek to use the southern exit of the North Sea, they would have to pass through the Strait of Dover and along the English Channel, which for 200nmi (230mi; 370km) was no more than 60nmi (69mi; 110km) wide. Using the northabout route past Scotland would consume a vast amount of coal and ships would have to make passage through another restricted and stormy sea of about 200nmi (230mi; 370km) width between the Orkney Islands and Shetland Islands off the north of Scotland and the Norwegian coast.[7]
A German ship that got as far as Cape Clear Island, at the extreme south-west of Ireland, would have to commandeer coal from captured ships, a risky and unreliable method of re-fuelling.[7] The British could exploit the same geographical and oceanic conditions to intercept German sea traffic and attempts of the Imperial German Navy (Kaiserliche Marine) to operate outside the North Sea. With the Grand Fleet based at Scapa Flow in the Orkneys, the northabout route would be blocked, with the assistance of a cruiser squadron keeping watch on the seas to the east and north of Shetland; other cruiser squadrons would watch a second line to the north.[7]
British naval preparations
In 1914, the British government expected that economic pressure would have a great effect on Germany.[8] The Admiralty war plan anticipated that Germany would be the main enemy in a European war and that a distant naval blockade would cut trade to and from Germany, including goods carried in neutral vessels. A special naval force was to patrol the sea routes between the north of Scotland and Norway and intercept traffic from the Atlantic into the North Sea. The Northern Patrol was to be provided by Cruiser Force B (later the 10th Cruiser Squadron) from Scapa Flow in Orkney.[1] The cruiser squadrons of the Grand Fleet based at Cromarty and Rosyth were to form a cordon further to the south as another blockade line. The administrative complications of the blockade overwhelmed the capacity of Vice Admiral Francis Miller, the Base Admiral in Chief from 7 August 1914, devolving on the commander in chief, Admiral John Jellicoe.[9] To relieve the administrative burdens on Miller and Jellicoe, the post of the Admiral Commanding, Orkneys and Shetlands was created to oversee the defence of the islands, naval bases and shore duties. Vice-Admiral Stanley Colville was appointed to the command (7 September 1914 – 19 January 1916) with Miller subordinate to him.[10]

The Canadian naval officer, Dudley de Chair, had a steady rise through the naval hierarchy and reached the rank of rear-admiral in 1912. Early in 1913 he became naval secretary to Winston Churchill, the First Lord of the Admiralty (1911–1915). After several full and frank exchanges of views with Churchill, de Chair was denied the command of the 2nd Cruiser Squadron that had been promised as his next appointment. De Chair received instead the post of Admiral of the Training Service, something of a snub, which included eight ageing Edgar-class cruisers built from 1889 to 1894. Under a 1913 war plan, the 10th Cruiser Squadron (10th CS) and 11th Cruiser Squadrons were to close the northabout route past the British Isles between Orkney, Shetland, Iceland and Norway but in 1914, the 11th Cruiser Squadron, as Cruiser Force E, was sent to the Persian Gulf, leaving the 10th Cruiser Squadron to make do.[11]
Mobilisation orders were issued by the Admiralty on 19 July 1914 and on 3 August, de Chair was ordered to take the Edgars to Scapa Flow in the Orkneys. The cruisers were ordered from their ports and en route the 10th CS captured SS William Behrens a German ship carrying timber which was sent to port under a prize crew. Endymion and Theseus made a delayed arrival on 6 August having chased SS Kronprinzessin Cecile, a German liner carrying precious metals, sending it into Falmouth. On 7 August Edgar sank two German trawlers which had tried to run instead of stopping when ordered. The seas between Scotland and Norway were notoriously dangerous; in the summer, mist and sudden high winds were common, for the rest of the year there were gales, stormy seas and long nights, with short, dull days under leaden skies. It was common for winds to reach force 9 or 10 on the Beaufort scale, raising seas higher than ships' masts.[12][lower-alpha 1] A local phenomenon, lumps, were waves which had superimposed and which, in a force 10 gale, arrived without warning, damaging ships and occasionally sinking them.[13]
Shetland (boxed) Orkney and Scotland to the south, Faroe Islands to the north-west and Norway to the east
The 10th CS reached full strength on 7 August and commenced operations to,
...intercept German vessels of war and German merchant vessels, and sink or capture them; also to stop all neutral vessels proceeding to German ports, and to deny the anchorage of any harbour in the Shetlands or Orkneys to the enemy.
The Edgars were first-class protected cruisers, old, Victorian ships. The ships carried two 9.2-inch (234 mm) guns and ten 6-inch (150 mm) quick-firers for the ships to fire broadside into opposing ships. The Edgars had been built to patrol the seas, protecting trade and overawing recalcitrant colonials. By 1914 they were in no condition to spend long periods in such dangerous seas; many of the crews were recalled pensioners, somewhat surprised to return to service. De Chair established a base at Swarbacks Minn, an anchorage on the west side of Shetland. On 10 August, de Chair formed the First Division with Crescent, Grafton, Endymion and Theseus; Edgar, Royal Arthur, Gibraltar and Hawke became the Second Division. The Shetland–Faroe gap was watched by the First Division and the Second Division was sent to watch the Orkney–Norway gap.[15] The Edgars were slow in speed and acceleration and had to make frequent returns to port for coaling, reducing each patrol to three ships. During autumn, the weather deteriorated and sometimes was so bad as to preclude boarding ships. The mechanical state of the ships declined, Gibraltar, Royal Arthur and Crescent soon needing repairs.[16]

During October, de Chair was ordered to patrol further to the south during a big operation to protect a convoy of 33 cruise liners transporting the Canadian Expeditionary Force to Britain. On 15 October, while patrolling off Aberdeen in line abreast at 10nmi (12mi; 19km) intervals, Hawke stopped to collect mail from Endymion then set off at 13kn (24km/h; 15mph) in a straight line to regain position. At 10:30 a.m.,Hawke was struck by a torpedo from U-9, capsized and sank. None of the other ships saw the sinking and found out only after U-9 attacked and missed Theseus. The patrol was ordered to head north-west at high speed but Hawke failed to acknowledge the signal. HMSSwift, an extremely fast destroyer, was sent from Scapa Flow to investigate and found a raft with 22 survivors. A Norwegian merchant ship rescued 49 men from a boat and transferred them to a British trawler but 524 members of the crew perished.[17] Before sailing, the captain, Hugh Williams, had visited Crescent and asked de Chair for another two days to make repairs to the engines. De Chair had refused since the ship could still sail at 10kn (19km/h; 12mph). As Williams left the flagship, he was reported saying
...it is pure murder sending the ship with over 500 officers and men on board to sea in this state.[18]
On 21 October, Crescent was surprised to be taken under fire by a tanker, north-north-west of Foula. The ship had no identification signs and Crescent replied at 7,000yd (6,400m), having been damaged by the tanker. The tanker soon caught fire on the deck and sent up a white flag. Due to the sea state, no boarding party was risked and the ship was escorted to Lerwick, where it was found to have been bought by the Kaiserliche Marine two months earlier, for service as an oceanic U-boat supply ship.[19]
The decrepitude of the Edgars continued to interfere with operations; on 29 October Grafton reported engine-trouble and unstable funnels. Theseus broke down chasing another ship and on 31 October reported more defects, being sent back to Swarbacks Minn to make repairs. Endymion docked at Scapa Flow and reported that it could not sail due to unserviceable engines and trouble with the fore bridge. On 11 November, Edgar had more engine trouble and had to return to Shetland when the weather had improved. Along with the frequent defects arising in the Edgars, Jellicoe ordered sweeps outside the cruisers' patrol areas reducing the Northern Patrol to nearly nothing. On 11 November, Crescent shipped a lump over the forecastle, which carried away de Chair's sea cabin, a whaler and swamped a ventilator, dousing several boilers; Edgar lost a crewmember and a cutter swept overboard. Afterwards, de Chair said that he had doubted that Crescent could survive. Crescent, Royal Arthur and Grafton were sent to the Clyde for repairs but the dockyard director stressed the diminishing returns that repairs would realise. On 20 November the Admiralty ordered the seven Edgars back to their home ports to be paid off. In under five months, the Edgars had boarded more than 300 ships and intercepted many others in storm-wracked seas.[20]
In mid-August 1914 the first AMC started operations with the Northern Patrol and soon enough AMCs were available to take over from the Edgars.[23] The AMCs were faster, longer-ranged, had better sea-keeping and more reliable machinery than the Edgars and provided their crews with far more comfortable quarters.[24] Later, armed trawlers were added to the force and warships from the Grand Fleet or other commands would temporarily be attached to the patrol. Admiral de Chair was replaced in March 1916 by Rear-Admiral (later vice-admiral) Reginald Tupper, who commanded the 10th Cruiser Squadron until it was disbanded on 29 November 1917.[25] The entry of the United States, the main source of contraband, into the war drastically reduced the need for the blockade. The ships of the force were transferred to convoy and anti-submarine work.[26] Royal Navy officers were appointed to command the AMCs and most of their masters stayed on as advisers. Many of their other mercantile officers were retained and the crews were drawn from the Royal Naval Reserve and the Mercantile Marine (many of whom had crewed the vessels in peacetime) with a "small number" from the Royal Fleet Reserve.[27]
One of four A-series liners requisitioned as armed merchant cruisers. In the action of 29 February 1916 she was torpedoed while engaging the merchant raider SMSGreif, both sank.[29]
Taken into French service as Champagne, retained British crew, packet ship from France to Archangelsk in Russia from 2 December 1915, torpedoed, Irish Sea by U-boat, 9 October 1917, 56 men lost[43]
Before the disbandment of the 10th Cruiser Squadron on 29 November 1917, the ships of the Northern Patrol inspected almost 13,000 merchant vessels at sea and only 642 ships managed to elude the blockade.[48] The cruiser HMS Hawke and ten AMCs (including Avenger) were lost. In 1980, A. Cecil Hampshire wrote that the blockade is generally considered to have been one of the main causes of the defeat of Germany in the First World War.[49]
Model of the armed merchant cruiser HMS Rawalpindi
In June 1939 the Admiralty began to call up reservists, 12,000 for the Reserve Fleet, as its ships were prepared to return to service; by 9 August the ships had received their complement of crews. The light cruisers were far from new, most being C-class cruisers and D-class cruisers of 4,000 and 5,000 long tons (4,100 and 5,100t), built during the First World War. The ships had five or six 6-inch (152 mm) guns, two 3-inch (76 mm) guns, four 3-pounder (47 mm) guns and eight 21-inch (533 mm) torpedo tubes; the ships had a maximum speed of 29kn (33mph; 54km/h). The ships had been designed for operations in the North Sea but had soon been sent onto far rougher waters. Six of the vessels had been used as boys' training ships. Two Emerald class light cruisers and the Hawkins-class cruiserHMSEffingham, the flagship of the Admiral Commanding, Northern Patrol, Vic-Admiral Max Horton were added.[50]
The Northern Patrol was re-established on 6 September 1939, three days after the start of the Second World War. Its area of operations was more extensive than during the First World War and included the areas north of Scotland and Ireland, between the north of Scotland and Norway, around Shetland, the Faeroe Islands and Iceland and the Denmark Strait between Iceland and Greenland.[51] Armed merchant cruisers soon replaced the light and heavy cruisers.[52] As in the First World War, warships from the Home Fleet or other commands were temporarily attached to the Northern Patrol.[53] The force operated within the command area of the Vice-Admiral or Rear-Admiral Commanding in the Orkneys and Shetlands who administered the islands and commanded the defences of Scapa Flow but was not subordinate to him.[54]
The three cruiser squadrons were supplemented and then replaced by armed merchant cruisers, the survivors of which were dispersed to other duties between late 1940 and 1941.[55]
By October 1939 the Admiralty had requisitioned 51 ships for use as armed merchant cruisers.[58] The first group of twenty AMCs were to fitted with Emergency Equipment in British ports with six more being converted overseas. The Emergency scale consisted of ancient 6-inch guns and mountings, a light director control, wooden magazines and shell-rooms and no divided storage for anti-aircraft ammunition. Only easily removed woodwork was to be removed such as furniture and bulkheads. The crew would be placed in the existing accommodation rather than broadside messes. Defensive shielding would be limited to protecting the bridge with sandbags and steel plates with more plates for the steering gear and machinery. It was hoped to have the ships operational in two and a half to three weeks. Complete Equipment was to follow, comprising full director systems, watertight magazines and shell rooms made of steel, broadside mess decks with hammocks, four paravanes per ship, the removal of more woodwork and thirteen 6-inch gun sets taken from C- and D-class cruisers once they were re-armed as anti-aircraft cruisers.[59]
Due to equipment shortages, the ships were fitted with six to nine 6-inch guns (some with 5.5-inch), two to four 3-inch or 4-inch anti-aircraft guns, several smaller guns and roll-off racks for a small number of depth charges. The guns and mountings were old, their ammunition had to be carried by hand and at 20° elevation reached their maximum range of only 14,000yd (6.9nmi; 8.0mi), the guns had director control but very little shielding. The armament of the C- and D-class cruisers had been intended for the AMCs but the decision to keep the cruisers in service precluded this. Royal Navy captains or commanders were put in command of the vessels, mostly dug-outs from retirement, accompanied by Navy first lieutenants, navigation and gunnery officers, some of whom were also Navy personnel and the rest of the officers were drawn from the RNR, some being the civilian officers of the ships, RNVR and T.124 agreement (voluntary enlistment and subject to RN discipline whilst retaining civilian rates of pay and conditions). A retired officer was embarked to help find neutral and belligerents' trawlers, often known to the trawler skippers and on good terms, which helped when bartering for part of the trawlers' catch. Ratings were drawn from the RN, RFR, RNR, RNVR, "hostilities only" and former Merchant Navy ratings on special agreements.[60]
The accommodations of AMCs were greatly superior to those on RN ships, even when fittings were removed to reduce the risk of fire. Lounges became wardrooms and junior ranks had a gunroom (junior officers' mess). Some cabins were used by chief and petty officers but most were demolished to make way for broadside messes to avoid delays when called to action stations. Holds and other spaces were filled with barrels or 40impgal (180L; 48USgal) oil drums as buoyancy ballast and called ping-pong balls. Even when laden with war stores the ships did not reach the peacetime GRT and carried heavy ballast of road stone or iron to maintain stability. Horton was uneasy at the new arrivals whose crews were somewhat unready for hostilities and boarded each ship with his technical officers to help the process of familiarisation with Navy methods. Horton asked for more long-range reconnaissance aircraft. Three days after HMSRoyal Oak had been torpedoed at Scapa Flow on 14 October 1939, the first seven AMCs arrived and by the end of November eleven AMCs were on patrol; Rawalpindi had already been sunk.[61]
SS Rawalpindi was requisitioned for the Northern Patrol by the Admiralty on 26 August 1939 and converted into an armed merchant cruiser. Eight elderly 6 in (150 mm) guns and two 3 in (76 mm) guns were added and the ship named HMSRawalpindi. On 19 October in the Denmark Strait, Rawalpindi intercepted the German tankerGonzenheim (4,574 grt), which had left Buenos Aires on 14 September. The tanker was scuttled by her crew before a boarding party could get on board. The ships sent a wireless message but this was not received by the Germans.[64]
On 26 September 1939, restrictions on the operation of the two German battleships Scharnhorst and Gneisenau in the Atlantic were terminated and after several short voyages, Grand Admiral Erich Raeder concluded that they were not vulnerable to the three Home Fleet battlecruisers in British home waters. On 12 November the Seekriegsleitung (SKL, Naval Warfare Command) of the Oberkommando der Marine (High Command of the Navy) decided to send the ships past the British ships watching the Faeroes–Iceland gap or those between Shetland and Norway, to threaten the British sea lanes in the North Atlantic. The operation was intended to be a feint, to divert British ships from the hunt for Graf Spee in the South Atlantic. The battleships sailed on 21 November and on 23 November reached the Faeroes–Iceland gap.
At 4:07 p.m.Scharnhorst sighted a ship at a distance of 25 km and immediately gave chase. After one hour the distance had closed to 7.5 km and Scharnhorst opened fire from 5:04 – 5:16 p.m.[65][2]Rawalpindi managed to get off a sighting report to the Admiralty, but it mentioned only one battlecruiser.[66] Despite being hopelessly outgunned, 60-year-old CaptainEdward Kennedy RN of Rawalpindi decided to fight.[67] He was heard to say "We'll fight them both, they'll sink us, and that will be that. Good-bye".[68]Rawalpindi sent a second sighting report identifying in error the opponent as the heavy cruiser Deutschland sailing homewards.[69]Rawalpindi sank in forty minutes but managed one hit on Scharnhorst, causing minor splinter damage. Scharnhorst rescued sixteen men and another twenty-one were rescued by Gneisenau.[70] Eleven men were later picked up by the AMC HMS Chitral but 238 men were killed.[68][lower-alpha 7] At 7:15 p.m. German lookouts spotted another ship in the darkness and gave alarm. The German ships retreated northwards as the British cruiser Newcastle arrived on the scene.[69] At 7:40 p.m. the German ships were informed that Rawalpindi had got off a sighting report that the German ships were sailing south-east. As the Home Fleet threatened to block their return to Germany, they sailed north-east into the Arctic Ocean and waited for a weather front before breaking unnoticed through a cruiser and destroyer patrol line on 26 November, safely returning to port.[72][73] The crews of Scharnhorst and Gneisenau were eligible for the Das Flottenkriegsabzeichen (High Seas Fleet Badge) for participating in the sinking of Rawalpindi.[74]
After the débâcle in France during May and June 1940, trawlers with the Northern Patrol were amongst those sent to the south-east of England took keep watch on home waters. The Admiralty had also floated a suggestion to Admiral Charles Forbes the commander-in-chief Home Fleet to move the Northern Patrol southwards to a line running north-west from the North Channel to watch for a German invasion of Ireland. Forbes threw cold water on the idea since an invasion force would sail west of the patrol line and that the AMCs would be vulnerable to U-boats which passed through the area en route to the Western Approaches. The Admiralty decided to mine the waters between Scotland and Iceland; the minefield was extended into the Denmark Strait to constrict the gap between the arctic ice off Greenland and the coast of Iceland with magnetic mines. Ships were directed to the Pentland Firth and between Orkney and the Faeroes. The Germans took the change to mean that the AMCs were being replaced by aircraft and cruisers but the AMCs remained.[76]
Raikes was replaced by Rear-Admiral Ernest Spooner on 16 July and for the rest of the month more patrols were sailed since the German invasion of Norway and four ships were sent for examination. The weather had at last improved and due to the war situation, shipping bound for the east coast ports had to take the route northabout Scotland. The admiralty decided on 21 July to extend the blockade to the French, Spanish and Portuguese Atlantic coasts and to French North Africa, naming it the Western Patrol. The ships were to be poached from the Northern Patrol but the new patrol was to remain under the existing command. Cilicia and Cheshire sailed on 19 July, to be joined by the trawlers Kingston Jacinth, Kingston Sapphire, Kingston Topaz and Kingston Turquoise. The number of ships on patrol in the area of the Northern Patrol had declined due to the detachments and because one AMC had been paid off and three transferred to the Atlantic and West Indies Command. Forbes ordered the Northern Patrol to watch the seas north of the Faeroes. When Spooner asked for ten more trawlers or corvettes he was told that none was available. Despite the success of the B-Dienst, part of German Naval Intelligence Service, the Marinenachrichtendienst, in reading British naval codes, the change went unnoticed.[77]
On 9 August, Transylvania, having departed the Clyde and passed near Ailsa Craig, was torpedoed just after midnight and began to sink by the stern. A distress call got an aircraft on the scene by 03:15 then three destroyers; only Transylvania's ping-pong balls had stopped it from sinking faster. No casualties had been suffered in the torpedo explosion but one boat was launched with only five men on board and disappeared. The rest of the crew who should have boarded, crowded onto another boat which capsized and another overcrowded boat capsized next to a destroyer. The confusion of the evacuation in the dark and in bad weather caused the worst loss to the Northern Patrol since the sinking of Rawalpindi. On the following day, California received a distress signal from SS Llanfair and Captain Pope had to decide whether to obey standing orders to avoid a danger area or attempt a rescue. A British aircraft was overhead of Llanfair, the sea state made another attack by a U-boat difficult and Pope decided to risk it. California dropped depth-charges as it arrived and picked up swiftly the thirty survivors, receiving orders not to attempt a rescue thirty minutes afterwards.[78]
On 18 November 1940, after the sinking of Laurentic and Patroclus the Admiralty decided to abolish the Northern Patrol except in the Denmark Strait; the Faeroes–Iceland gap was to be left to the trawlers and minefields. Surplus ships were to be diverted to the Western Patrol. The average number of ships on the Northern Patrol was cut to five out of the eleven ships left, with three on the Western Patrol. The Northern Patrol checked fifteen ships and the Western Patrol 155, three from the latter being sent under guard for inspection. Klaus Schoke (5,800 GRT) of the Hansa Line departed on 1 December for Ponta Delgada in the Azores for Vigo in Spain but was stopped by the AMC California. The crew tried to scuttle the ship and despite attempts to save the ship it sank on 5 December. On the Northern Patrol, Forfar had refitted at Liverpool, sailed on 30 November escorted by a destroyer, which was ordered back near midnight on 1 December.[80]
Forfar was ordered to divert south around a U-boat said to be in the area of 54° 23' N and 20° 11' west. Course was changed and before joining the Western Patrol, was diverted to escort the eastbound Convoy SC 14. Forfar sailed near Convoy HX 90 by coincidence, which was being shadowed by four U-boats; at 03:30 the lookouts spotted something but the captain of Forfar decided to maintain the zig-zag and at 04:40 Forfar was struck by a torpedo. Within the hour, four more torpedoes hit the ship; many of the lifeboats were caught in the explosions making an organised evacuation impossible, many men going into water slicked with oil. SSDunsley, a straggler from Convoy HX 90, which had fought off a surface attack by U-99, arrived on the scene and rescued some survivors, a Sunderland flying boat managed to miss others but destroyers rescued the remaining survivors during the next afternoon. Members of the crew had been killed in the torpedo explosions, others died of wounds and another 178 were killed after abandoning ship; it was the worst disaster to the Northern Patrol since the sinking of Rawalpindi.[80]

Scapa Flow is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray, South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World wars, but the facility was closed in 1956.
HMS King George V was the lead ship of her class of four dreadnought battleships built for the Royal Navy in the early 1910s. She spent the bulk of her career assigned to the Home and Grand Fleets, often serving as a flagship. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during the First World War generally consisted of routine patrols and training in the North Sea.
HMS Centurion was the second of four King George V-class dreadnought battleships built for the Royal Navy in the early 1910s. She spent the bulk of her career assigned to the Home and Grand Fleets. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, and the Battle of Jutland in May 1916, her service during the First World War generally consisted of routine patrols and training in the North Sea.
HMS Ajax was the third of four King George V-class dreadnought battleships built for the Royal Navy in the early 1910s. After commissioning in 1913, she spent the bulk of her career assigned to the Home and Grand Fleets. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during World War I generally consisted of routine patrols and training in the North Sea.
HMS Thunderer was the fourth and last Orion-class dreadnought battleship built for the Royal Navy in the early 1910s. She spent the bulk of her career assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during World War I generally consisted of routine patrols and training in the North Sea.
HMS St Vincent was the lead ship of her class of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. After commissioning in 1910, she spent her whole career assigned to the Home and Grand Fleets, often serving as a flagship. Aside from participating in the Battle of Jutland in May 1916, during which she damaged a German battlecruiser, and the inconclusive action of 19 August several months later, her service during World War I generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war and was reduced to reserve and used as a training ship. St Vincent was sold for scrap in 1921 and broken up the following year.
HMS Bellerophon was the lead ship of her class of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. She spent her whole career assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during the First World War generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war and was used as a training ship before she was placed in reserve. Bellerophon was sold for scrap in 1921 and broken up beginning the following year.
The Grand Fleet was the main battlefleet of the Royal Navy during the First World War. It was established in August 1914 and disbanded in April 1919. Its main base was Scapa Flow in the Orkney Islands.
The Home Fleet was a fleet of the Royal Navy that operated from the United Kingdom's territorial waters from 1902 with intervals until 1967. In 1967, it was merged with the Mediterranean Fleet creating the new Western Fleet.
HMS Erin was a dreadnought battleship of the Royal Navy, originally ordered by the Ottoman government from the British Vickers Company. The ship was to have been named Reşadiye when she entered service with the Ottoman Navy. The Reşadiye class was designed to be at least the equal of any other ship afloat or under construction. When the First World War began in August 1914, Reşadiye was nearly complete and was seized at the orders of Winston Churchill, the First Lord of the Admiralty, to keep her in British hands and prevent her from being used by Germany or German allies. There is no evidence that the seizure played any part in the Ottoman government declaring war on Britain and the Triple Entente.
Operation Berlin was a raid conducted by the two German Scharnhorst-class battleships against Allied shipping in the North Atlantic between 22 January and 22 March 1941. It formed part of the Battle of the Atlantic during World War II. The Scharnhorst and Gneisenau sailed from Germany, operated across the North Atlantic, sank or captured 22 Allied merchant vessels, and finished their mission by docking in occupied France. The British military sought to locate and attack the German battleships, but failed to damage them.
HMS Rawalpindi was a British armed merchant cruiser that was sunk in a surface action against the German battleships Scharnhorst and Gneisenau during the first months of the Second World War. Her captain was Edward Kennedy.
HMS Mashona was one of 16 Tribal-class destroyers built for the Royal Navy shortly before the beginning of Second World War in 1939. Completed in that year, she was assigned to the Home Fleet. During the first year of the war, the ship was on convoy escort duties. Mashona played an active role in the Norwegian Campaign of April–May 1940, escorting convoys to and from Norway. The ship helped to briefly seize four Swedish warships en route from Italy to Sweden in June 1940 and resumed her role of convoy escort after their release in July. She accidentally collided with one of her sister ships in early 1941 and spent several months under repair.
The Action of 16 March 1917 was a naval engagement in which the British armed boarding steamer SS Dundee and HMS Achilles, a Warrior-class armoured cruiser, fought the German auxiliary cruiser SMS Leopard, which sank with the loss of all 319 hands and six men of a British boarding party.
The action of 29 February 1916 was a naval engagement fought during the First World War between the United Kingdom and the German Empire. SMS Greif, a German commerce raider, broke out into the North Sea and Admiral Sir John Jellicoe dispatched Royal Navy warships to intercept the raider. Four British vessels intercepted the commerce raider Greif. The armed merchant cruiser RMS Alcantara and Greif fought a brief engagement before British reinforcements arrived when both were severely damaged, both being sunk.
The action off Lerwick was a naval engagement on 17 October 1917 fought in the North Sea during the First World War. The German light, minelaying cruisers SMS Brummer and Bremse attacked a westbound convoy of twelve colliers and other merchant ships and their escorts, part of the regular Scandinavian convoy. The two escorting destroyers and nine neutral Scandinavian ships were sunk off Shetland, Scotland.
Gneisenau was a German capital ship, alternatively described as a battleship and battlecruiser, in Nazi Germany's Kriegsmarine. She was the second vessel of her class, which included her sister ship, Scharnhorst. The ship was built at the Deutsche Werke dockyard in Kiel; she was laid down on 6 May 1935 and launched on 8 December 1936. Her outfitting was completed in May 1938: she was armed with a main battery of nine 28 cm (11 in) C/34 guns in three triple turrets. At one point after construction had started, a plan had been approved to replace these weapons with six 38 cm (15 in) SK C/34 guns in twin turrets, but when it was realized that this would involve a lot of redesign, that plan was abandoned, and construction continued with the originally planned lower-calibre guns. The upgrade had been intended to be completed in the winter of 1940–41, but instead, due to the outbreak of World War II, that work was stopped.
The Admiral Commanding, Orkneys and Shetlands was an operational commander of the Royal Navy. He was charged with the administration of the Orkney and Shetland Islands and operating and defending the fleet base at Scapa Flow that was the main anchorage for both the Home Fleet and Grand Fleet at various times.
The action of 11–12 December 1917 was a German naval operation in the North Sea against convoys sailing on the Scandinavian convoy route from Norway to Lerwick in the Shetland Islands during the First World War. Ships carrying coal from the loading port of Immingham on the Humber estuary were convoyed to Lerwick up the war channel, along the east coast of Northern England and Scotland, for dispatch in convoys to Scandinavian neutrals, along with ships carrying general cargo.
Operation Northern Mark was a sortie by a German flotilla of two battleships and a heavy cruiser against British merchant shipping between Norway and Shetland from 18 to 20 February 1940. The sortie was intended as a riposte to the Altmark incident, to create confusion to help German blockade-runners reach home and as a prelude to more ambitious operations in the Atlantic. The flotilla was spotted by the British early on, who held back a Norway-bound convoy.
