RMS Lusitania

Lusitania

RMS Lusitania was a British ocean liner, named after the ancient Roman province of Lusitania, which is part of present day Portugal. The ship entered passenger service with the Cunard Line on 26 August 1907 and continued on the line's heavily traveled passenger service between Liverpool, England and New York City, which included a port of call at Queenstown, (now Cobh) Ireland on westbound crossings and Fishguard, Wales on eastbound crossings.
During the First World War, as Germany waged submarine warfare against Britain, the ship was identified and torpedoed by the GermanU-boat U-20 on 7 May 1915 and sank in 18 minutes. The vessel went down 11 miles (18 km) off the Old Head of Kinsale,[4] Ireland, killing 1,198 of the 1,959 people aboard, leaving 761 survivors. The sinking turned public opinion in many countries against Germany, contributed to the American entry into World War I and became an iconic symbol in military recruiting campaigns of why the war was being fought.[5]
Lusitania was constructed as part of the competition between the Cunard Line and other shipping lines, principally from Germany, for the transatlantic passenger trade. Whichever company had the fastest and most luxurious ships had a commercial advantage: Lusitania and her sister Mauretania together provided a regular express service between Britain and the United States until the intervention of the First World War. The two ships both held the Blue Riband speed record for a transatlantic crossing at different times in their careers.Mauretania was generally the slightly faster of the two and continued to hold the record after the war until 1929.
The Cunard board had decided to use Parsonsturbine propulsion, which accounted for their 22-year retention of the speed record with her running mate RMS Mauretania. The turbines produced more horsepower, and (theoretically) less onboard noise and vibration, compared to expansion engines used in earlier vessels. The ships were the largest ever built at the time they were constructed, and had 50% greater passenger space than their nearest rivals, allowing unprecedented luxury for all Saloon, Cabin, and Steerage passengers.
The Lusitania was designed so that she might readily be converted to an auxiliary cruiser in times of war as part of an agreement with the British government who provided a loan of £2.6 million to finance her and Mauretania's construction. The ships attracted an ongoing operating subsidy and also held a valuable mail contract. In the event, the ships proved to be impractical armed cruisers (the liners all had very high fuel consumption and were found to be too expensive for the Admiralty to operate). Lusitania and other express liners were released from the Royal Navy shortly after the commencement of the war with instructions to resume passenger services, whileMauretania performed service as a troop ship. Cunard expressed a desire to lay up the ship for the duration of the war, but under the terms of the subsidy contract they were required to make all their ships available for government use and to carry government cargoes.
Lusitania had the misfortune to fall victim to torpedo attack relatively early in the First World War, before tactics for evading submarines were properly implemented or understood. The contemporary investigations both in the UK and the United States into the precise causes of the ship's loss were obstructed by the needs of wartime secrecy and a propaganda campaign to ensure all blame fell upon Germany. Argument over whether the ship was a legitimate military target raged back and forth throughout the war as both sides made misleading claims about the ship. At the time she was sunk, she was carrying a large quantity of rifle ammunition and other supplies necessary for awar economy, as well as civilian passengers. Several attempts have been made over the years since the sinking to dive to the wreck seeking information about precisely how the ship sank, and argument continues to the current day.

Development and construction

Lusitania and her sister ship Mauretania were commissioned by Cunard, responding to increasing competition from rival transatlantic passenger companies, particularly the GermanNorddeutscher Lloyd (NDL) and Hamburg America Line (HAPAG). They had larger, faster, modern, more luxurious ships than Cunard and were better placed, starting from German ports, to capture the lucrative trade in emigrants leaving Europe for America. In 1897 the NDL liner Kaiser Wilhelm der Grosse captured the Blue Riband from Cunard's Campania, before the prize was taken in 1900 by the HAPAG ship Deutschland. NDL soon wrested the prize back in 1903 with the new Kaiser Wilhelm II and Kronprinz Wilhelm. Cunard saw their business steadily declining[6] as a result of the so called Kaiser class ocean liners.
The American millionaire businessman J. P. Morgan had decided to invest in transatlantic shipping by creating a new company International Mercantile Marine (IMM), and in 1901 purchased the British freight shipper Frederick Leyland & Co. and a controlling interest in the British passenger White Star Line and folded them into IMM. In 1902, IMM, NDL, and HAPAG entered into a "Community of Interest" to fix prices and divide between them the transatlantic trade. The partners also acquired a 51% stake in the Dutch Holland America Line. IMM made offers to purchase Cunard which, along with the French CGT, were now their principal rivals. Cunard declined the offer, but lacked the financial resources to respond with new ships. Cunard chairman Lord Inverclyde thus approached the British government for assistance. Faced with the impending collapse of the British liner fleet and the consequent loss of national prestige, as well as the reserve of shipping for war purposes which it represented, they agreed to help. By an agreement signed in June 1903, Cunard was given a loan of £2.6 million to finance two ships, repayable over 20 years at a favourable interest rate of 2.75%. The ships would receive an annual operating subsidy of £75,000 each plus a mail contract worth £68,000. In return the ships would be built to Admiralty specifications so that they could be used as auxiliary cruisers in wartime.

Design

Cunard established a committee to decide the design for the new ships. James Bain, Cunard's Marine Superintendent was the chairman, while other members included Rear Admiral H. J. Oram, who had been involved in designs for turbine powered ships for the navy, and Charles Parsons, whose company Parsons Marine was now producing revolutionary turbine engines. Parsons maintained that he could design engines capable of maintaining a speed of 25 knots, which would require 68,000 horse power. The largest turbine sets built thus far had been of 23,000 bhp for the Dreadnought class battleships, and 41,000 bhp for Invincible class battlecruisers, which meant the engines would be of a new untested design. Turbines offered the advantages of less vibration in operation, greater reliability at high speeds and better fuel consumption. It was agreed that a trial would be made by fitting turbines to Carmania which was already under construction. The result was a ship 1.5 knots faster than her conventionally powered sister Caronia with the expected improvements in passenger comfort and operating economy.
The ship was designed by Leonard Peskett[9] and built by John Brown and Company of ClydebankScotland. Peskett had built a large model of the proposed ship in 1902 showing a three funnel design. A fourth funnel was implemented into the design in 1904 as it was necessary to vent the exhaust from additional boilers fitted after steam turbines had been settled on as the powerplant. The original plan called for three propellers, but this was altered to four because it was felt the necessary power could not be transmitted through just three. Four turbines would drive four separate propellers with additional reversing turbines connected to the two inner shafts only. To improve efficiency, the two propellers either side nearest the rudder rotated inwards, while the outer propellers rotated outwards. The outer turbines operated at high pressure, with the exhaust steam then passing to the inner low pressure turbines. The propellers were driven directly by the turbines since sufficiently robust gearboxes were not available until developed by Parsons in 1916. Instead turbines had to be designed to run much slower than their optimum efficient speeds. The efficiency of the installed turbines was less at low speeds than a conventional triple expansion piston steam engine, but significantly better when the engines were run at high speed, as was usually the case for an express liner. There were 23 double ended boilers and two single ended (fitting the forward space where the ship narrowed), operating at a maximum 195 psi and containing 192 individual furnaces.
Work to refine the hull shape was conducted in the Admiralty experimental tank at Haslar, Gosport. As a result of experiments the beam of the ship was increased 10 feet (3.0 m) compared to the initial design to improve stability. The hull immediately in front of the rudder and the balanced rudder itself followed naval design practice to improve rapid turning. The Admiralty contract required that all machinery be below the waterline, where it was considered to be better protected from gunfire. The rear third of the ship below water was used for the turbines, steering motors and four steam turbine driven 375 kW generators. The central half contained four boiler rooms, with the remaining space at the front of the ship reserved for cargo and other storage. Coal bunkers were placed along the length of the ship sandwiched between the hull and the boiler rooms, with a large transverse bunker immediately in front of the most forward, number 1 boiler room. Apart from convenience ready for use, the coal was considered to provide added protection for the central spaces against attack. At the very front were the chain lockers for the huge anchor chains and ballast tanks to adjust the ships trim. The hull space was divided into twelve watertight compartments, any two of which could be flooded without the ship sinking, connected by 35 hydraulically operated watertight doors. A critical difficulty with the watertight compartment design was that sliding doors to the coalbunkers needed to be open to feed coal all the time the ship was operating and closing these in emergency conditions could be problematic. The ship had a double bottom, with the space between divided into separate watertight cells. The ship's exceptional height was due to the six decks of passenger accommodation above the waterline, compared to the customary four decks in existing liners.[11]
High tensile steel was used for the ship's plating rather than the conventional mild steel. This allowed a reduction in plate thickness, reducing weight but still providing 26% greater strength than otherwise. Plates were held together by triple rows of rivets. The ship was heated and cooled throughout by a thermo-tank ventilation system, which used steam driven heat exchangers to warm air to a steady 65 °F (18.3 °C) while steam was injected into the airflow to maintain steady humidity. Forty-nine separate units driven by electric fans supplied seven complete air changes per hour throughout the ship in an interconnected system so that units could be switched out for maintenance. A separate system of exhaust fans removed air from galleys and bathrooms. As built, the ship conformed fully with Board of Trade safety regulations, which required sixteen lifeboats, with a capacity of approximately 1000 people.[12]
Lusitania was briefly the largest ship ever built at the time of her completion (due to the slightly larger Mauretania, entering service shortly after.). She was 70 feet (21 m) longer, two knots faster, and 10,000 tons larger than the most modern German liner, Kronprinzessin Cecilie. Passenger accommodation was 50% larger than any of her competitors providing for 552 saloon class, 460 cabin class and 1,186 in third class. Her crew comprised 69 on deck, 369 operating engines and boilers and 389 to attend to passengers. She had wireless telegraph, electric light, electrical lifts, and sumptuous interiors.

Interiors

At the time of their introduction both Lusitania and Mauretania possessed the most luxurious interiors afloat. The Scottish architect James Millar was chosen to design Lusitania's interiors, while Harold Peto was chosen to design Mauretania. Millar chose to use plasterwork to create interiors whereas Peto made extensive use of wooden panelling, with the result that the overall impression given by Lusitania was brighter than MauretaniaLusitania's designs proved the more popular.
In common with all major liners of the period, Lusitania’s interiors were decorated with a mélange of historical styles. The first class dining saloon was the grandest of the ship’s public rooms; arranged over two decks with an open circular well at its centre and crowned by an elaborate dome measuring 29 feet (8.8 m), decorated with frescos in the style of François Boucher, it was elegantly realized throughout in the neoclassical Louis XVI style.[14] The lower floor measuring 85 feet (26 m) could seat 323, with a further 147 on the 65 feet (20 m) upper floor. The walls were finished with white and gilt carved mahogany panels, with corinthian decorated columns where required to support the floor above. The one concession to seaborne life was that furniture was bolted to the floor, meaning passengers could not rearrange their seating for their personal convenience.
All other first class public rooms were situated on the boat deck and comprised a lounge, reading and writing room, smoking room and veranda café. The last was an innovation on a Cunard liner and, in warm weather, one side of the café could be opened up to give the impression of sitting outdoors. However this would have been a rarely used feature given the often inclement weather of the north Atlantic.[15] The first class lounge was decorated in Georgian style with inlaid mahogany panels surrounding a jade green carpet with a yellow floral pattern, measuring overall 68 feet (21 m). It had a barrel vaulted skylight rising to 20 feet (6.1 m) with stained glass windows each representing one month of the year. Each end of the lounge had a 14 feet (4.3 m) high green marble fireplace incorporating enamelled panels by Alexander Fisher. The design was linked overall with decorative plasterwork. The library walls were decorated with carved pillasters and mouldings marking out panels of grey and cream silk brocade. The carpet was rose, with Rose du Barry silk curtains and upholstery. The chairs and writing desks were mahogany, and the windows featured etched glass. The smoking room was Queen Anne style, with Italian walnut panelling and Italian red furnishings. The grand stairway linked all six decks of the passenger accommodation with wide hallways on each level and two lifts. First class cabins ranged from one shared room through various ensuite arrangements in a choice of decorative styles culminating in the two regal suites which each had two bedrooms, dining room, parlour and bathroom. The port suite decoration was modelled on the Petit Trianon.
The second class public rooms were situated in a separate section of the superstructure aft of the first class passenger quarters. Design work was deputised to Robert Whyte, who was the architect employed by John Brown. Although smaller and plainer, the design of the dining room reflected that of first class, with just one floor of diners under a ceiling with a smaller dome and balcony. Walls were panelled and carved with decorated pillars, all in white. As with first class, the dining room was situated lower down in the ship on the saloon deck. The smoking and ladies rooms occupied the accommodation space of the second class promenade deck, with the lounge on the boat deck. Cunard had not previously provided a separate lounge for second class; the 42 feet (13 m) room had mahogany tables, chairs and setees set on a rose carpet. The smoking room was 52 feet (16 m) with mahogany panelling, white plasterwork ceiling and dome. One wall had a mosaic of a river scene in Brittany, while the sliding windows were blue tinted. There were no second class cabin suites, only standard shared cabins.[17]
Third class accommodation was plainer still, but, in comparison to other ships of the period, surprisingly comfortable and spacious. The 79 feet (24 m) dining room was at the bow of the ship on the saloon deck, finished in polished pine as were the other third class public rooms. Meals were eaten at long tables and there were two sittings for meals. A piano was provided for passenger use. A ladies lounge and smoking room were provided on the shelter deck immediately above the dining room. The roofed and partially enclosed space between the two had seating and provided some third class sheltered deck access in bad weather. Cabins were shared with a mixture of 2, 4 or 6 bunks and a wash basin, which was a significant improvement on previously typical dormitories.[18]
The Bromsgrove Guild had designed and constructed most of the trim on Lusitania.[19] Waring and Gillow tendered for the contract to furnish the whole ship, but failing to obtain this still supplied a number of the furnishings.

Construction and trials

Lusitania's keel was laid at John Brown on Clydebank as yard no. 367 on 16 June 1904, Lord Inverclydehammering home the first rivet. Cunard nicknamed her 'the Scottish ship' in contrast to her sister whose contract went to Swan Hunter in England and who started building three months later. Final details of the two ships were left to designers at the two yards so that the ships differed in details of hull design and finished structure. The ships may most readily be distinguished in photographs through the flat topped ventilators used on Lusitania, whereas those on Mauretania used a more conventional rounded top. Mauretania was designed a little longer, wider, heavier and with an extra power stage fitted to the turbines.
The shipyard at John Brown had to be reorganised because of her size so that she could be launched diagonally across the widest available part of the river Clyde where it met a tributary, the ordinary width of the river being only 610 feet (190 m) compared to the 786-foot (240 m) long ship. The new slipway took up the space of two existing ones and was built on reinforcing piles driven deeply into the ground to ensure it could take the temporary concentrated weight of the whole ship as it slid into the water. Construction commenced at the bow working backwards, rather than the traditional approach of building both ends towards the middle. This was because designs for the stern and engine layout were not finalised when construction commenced. Railway tracks were laid alongside the ship and across deck plating to bring materials as required. The hull, completed to the level of the main deck but not fitted with equipment weighed approximately 16,000 tons.
The ship's stockless bower anchors weighed 1014 tons, attached to 125 ton, 330 fathom chains all manufactured by N. Hingley and Sons, Ltd. The steam capstans to raise them were constructed by Napier brothers Ltd, of Glasgow. The turbines were 25 feet (7.6 m) long with 12 ft (3.7 m) diameter rotors, the large diameter necessary because of the relatively low speeds at which they operated. The rotors were constructed on site, while the casings and shafting was constructed in John Brown's Atlas works in Sheffield. The machinery to drive the 56 ton rudder was constructed by Brown Brothers of Edinburgh. A main steering engine drove the rudder through worm gear and clutch operating on a toothed quadrant rack, with a reserve engine operating separately on the rack via a chain drive for emergency use. The 17 ft (5.2 m) three bladed propellers were fitted and then cased in wood to protect them during the launch.[21]
The ship was launched on 7 June 1906, eight weeks later than planned because of strikes and eight months after Lord Inverclyde's death. Princess Louise was invited to name the ship but could not attend, so the honour fell to Inverclyde's widow Mary.[22][23] The launch was attended by 600 invited guests and thousands of spectators.[24] 1000 tons of drag chains were attached to the hull by temporary rings to slow it once it entered the water. The wooden supporting structure was held back by cables so that once the ship entered the water it would slip forward out of its support. Six tugs were on hand to capture the hull and move it to the fitting out berth.[25]
Testing of the ship's engines took place in June 1907 prior to full trials scheduled for July. A preliminary cruise was arranged for 27 July with representatives of Cunard, the Admiralty, the Board of Trade, and John Brown aboard. The ship achieved speeds of 25.6 knots over a measured mile at Skelmorlie with turbines running at 194 revolutions per minute producing 76,000 shp. However, at high speeds the ship was found to suffer such vibration at the stern as to render the second class accommodation uninhabitable. VIP invited guests now came on board for a two day shakedown cruise during which the ship was tested under continuous running at speeds of 15, 18 and 21 knots but not her maximum speed. On 29 July the guests departed and three days of full trials commenced. The ship travelled four times between the Corsewall Light off Scotland to the Longship Light off Cornwall at 23 and 25 knots, between the Corsewall Light and Isle of Man, and Isle of Aran and Ailsa Craig. Over 300 miles (480 km) an average speed of 25.4 knots was achieved, comfortably greater than the 24 knots required under the admiralty contract. The ship could stop in 4 minutes in 3/4 of a mile starting from 23 knots at 166 rpm and then applying full reverse. She achieved a speed of 26 Knots over a measured mile loaded to a draught of 33 feet (10 m), and managed 26.5 knots over a 60-mile (97 km) course drawing 31.5 feet (9.6 m). At 180 revolutions a turning test was conducted and the ship performed a complete circle of diameter 1000 yards in 50 seconds. The rudder required 20 seconds to be turned hard to 35 degrees.[26][27]
The vibration was determined to be caused by interference between the wake of the outer propellers and inner and became worse when turning. At high speeds the vibration frequency resonated with the ships stern making the matter worse. The solution was to add internal stiffening to the stern of the ship but this necessitated gutting the second class areas and then rebuilding them. This required the addition of a number of pillars and arches to the decorative scheme. The ship was finally delivered to Cunard on 26 August although the problem of vibration was never entirely solved and further remedial work went on through her life.[28] In June 1908 the two outer propellers were replaced with others having a greater blade pitch which produced a modest improvement in performance. In April 1909 all four propellers were replaced with a four bladed design similar to those fitted on Mauretania with a six foot larger diameter weighing 23 tons. This change resulted in an approximate 1 knot increase in maximum speed and reduced vibration.

Comparison with the Olympic class

Lusitania and Mauretania were smaller than the White Star Line's Olympic-class vessels. Both vessels had been launched and had been in service for several years before the Olympic class ships were ready for the North Atlantic. Although significantly faster than the Olympic class would be, the speed of Cunard's vessels was not sufficient to allow the line to run a weekly two-ship transatlantic service from each side of the Atlantic. A third ship was needed for a weekly service, and in response to White Star's announced plan to build the three Olympic class ships, Cunard ordered a third ship: Aquitania. Like White Star Line's Olympic, Cunard's Aquitania had a lower service speed, but was a larger and more luxurious vessel.
The vessels of the Olympic class also differed from Cunard's Lusitania and Mauretania in the way in which they were compartmented below the waterline. The White Star vessels were divided by transverse watertight bulkheads. While Cunard's Lusitania also had transverse bulkheads, she additionally had longitudinal bulkheads running along the ship on each side, between the boiler and engine rooms and the coal bunkers on the outside of the vessel. The British commission that had investigated the Titanic disaster in 1912 heard testimony on the flooding of coal bunkers lying outside longitudinal bulkheads. Being of considerable length, when flooded, these could increase the ship's list and "make the lowering of the boats on the other side impracticable".[29] — and this was precisely what later happened with Lusitania. Furthermore the ship's stability was insufficient for the bulkhead arrangement used: flooding of only three coal bunkers on one side could result in negative metacentric height.[30] On the other hand Titanic was given ample stability and sank with only a few degrees list, the design being such that there was very little risk of unequal flooding and possible capsize.

Career

Lusitania, commanded by Commodore James Watt, moored at the Liverpool landing stage for her maiden voyage at 16:30 on Saturday 7 September 1907 as the onetime Blue Riband holder RMS Lucania vacated the pier. At the time Lusitania was the largest ocean liner in service and would continue to be until the introduction of Mauretania in November that year. During her eight-year service, she made a total of 202 crossings on the Cunard Line's Liverpool-New York Route.
A crowd of 200,000 people gathered to see her departure at 21:00 for Queenstown, where she was to take on more passengers. She anchored again at Roches Point, off Queenstown, at 09:20 the following morning, where she was shortly joined by Lucania, which she had passed in the night, and 120 passengers were brought out to the ship by tender bringing her total of passengers to 2,320. At 12:10 on Sunday Lusitania was again under way and passing the Daunt Rock Lightship. In the first 24 hours she achieved 561 miles (903 km), with further daily totals of 575, 570, 593 and 493 miles (793 km) before arriving at Sandy Hook at 09:05 Friday 13 September, taking in total 5 days and 54 minutes, 30 minutes outside the record time held by Kaiser Wilhelm II of the North German Lloyd line. Fog had delayed the ship on two days, and her engines were not yet run in. In New York hundreds of thousands of people gathered on the bank of the River Hudson from Battery Park to pier 56. All New York's police had been called out to control the crowd. 100 horse drawn cabs had been queuing from the start of the day ready to take away passengers. During the week's stay the ship was made available for guided tours. At 15:00 on Saturday 21 September, the ship departed on the return journey, arriving Queenstown 04:00 27 September and Liverpool 12 hours later. The return journey was 5 days 4 hours and 19 minutes, again delayed by fog.
On her second voyage in better weather, Lusitania arrived at Sandy Hook on 11 October 1907 in the Blue Riband record time of 4 days, 19 hours and 53 minutes. She had to wait for the tide to enter harbour where news had proceeded her and she was met by a fleet of small craft, whistles blaring. Lusitania averaged 23.99 knots (44.43 km/h) westbound and 23.61 knots (43.73 km/h) eastbound. In December 1907, Mauretania entered service and took the record for the fastest eastbound crossing. Lusitania made her fastest westbound crossing in 1909 after her propellers were changed, averaging 25.85 knots (47.87 km/h). She briefly recovered the record in July of that year, but Mauretania recaptured the Blue Riband the same month, retaining it until 1929, when it was taken by SS Bremen.

Hudson Fulton Celebration

Lusitania and other ships participated in the Hudson-Fulton Celebration in New York City from the end of September to early October 1909. This was in celebration of the 300th anniversary of Henry Hudson's trip up the river that bears his name and the 100th anniversary of Robert Fulton's steamboat, Clermont. The celebration also was a display of the different modes of transportation then in existence, Lusitaniarepresenting the newest advancement in steamship technology. A newer mode of travel was the aeroplane. Wilbur Wright had brought a Flyer to Governors Island and proceeded to make demonstration flights before millions of New Yorkers who had never seen an aircraft. Some of Wright's trips were directly over Lusitania; several photographs of Lusitania from that week still exist.

War

When Lusitania was built, her construction and operating expenses were subsidised by the British government, with the proviso that she could be converted to an Armed Merchant Cruiser if need be. At the outbreak of the First World War, the British Admiralty considered her for requisition as an armed merchant cruiser, and she was put on the official list of AMCs. The Admiralty then cancelled their earlier decision and decided not to use her as an AMC after all; large liners such as Lusitania consumed enormous quantities of coal (910 tons/day, or 37.6 tons/hour) and became a serious drain on the Admiralty's fuel reserves, so express liners were deemed inappropriate for the role when smaller cruisers would do. They were also very distinctive; so smaller liners were used as transports instead. Lusitania remained on the official AMC list and was listed as an auxiliary cruiser in the 1914 edition of Jane's All the World's Fighting Ships, along with Mauretania.
At the outbreak of hostilities, fears for the safety of Lusitania and other great liners ran high. During the ship’s first east-bound crossing after the war started, she was painted in a drab grey colour scheme in an attempt to mask her identity and make her more difficult to detect visually. When it turned out that the German Navy was kept in check by the Royal Navy, and their commerce threat almost entirely evaporated, it very soon seemed that the Atlantic was safe for ships like Lusitania, if the bookings justified the expense of keeping them in service.
Germany's declared exclusion zone of February 1915. Ships within this area were liable to search and attack
Many of the large liners were laid up over the autumn and winter of 1914–1915, in part due to falling demand for passenger travel across the Atlantic, and in part to protect them from damage due to mines or other dangers. Among the most recognizable of these liners, some were eventually used as troop transports, while others became hospital ships. Lusitania remained in commercial service; although bookings aboard her were by no means strong during that autumn and winter, demand was strong enough to keep her in civilian service. Economizing measures were taken, however. One of these was the shutting down of her No. 4 boiler room to conserve coal and crew costs; this reduced her maximum speed from over 25 knots (46 km/h) to 21 knots (39 km/h). Even so, she was the fastest first-class passenger liner left in commercial service.
With apparent dangers evaporating, the ship’s disguised paint scheme was also dropped and she was returned to civilian colours. Her name was picked out in gilt, her funnels were repainted in their traditional Cunard livery, and her superstructure was painted white again. One alteration was the addition of a bronze/gold coloured band around the base of the superstructure just above the black paint.

1915

The official warning issued by the Imperial German Embassy about travelling on Lusitania.
By early 1915 a new threat began to materialize: submarines. At first they were used by the Germans only to attack naval vessels, and they achieved only occasional – but sometimes spectacular – successes. Then the U-boats began to attack merchant vessels at times, although almost always in accordance with the old cruiser rules. Desperate to gain an advantage on the Atlantic, the German government decided to step up their submarine campaign. On 4 February 1915 Germany declared the seas around the British Isles a war zone: from 18 February allied ships in the area would be sunk without warning. This was not wholly unrestricted submarine warfare since efforts would be taken to avoid sinking neutral ships.
Lusitania was scheduled to arrive in Liverpool on 6 March 1915. The Admiralty issued her specific instructions on how to avoid submarines. Despite a severe shortage of destroyers, Admiral Henry Oliver ordered HMS Louis and Laverock to escortLusitania, and took the further precaution of sending the Q ship Lyons to patrol Liverpool Bay.[37] The destroyer commander attempted to discover the whereabouts of Lusitania by telephoning Cunard, who refused to give out any information and referred him to the Admiralty. At sea, the ships contacted Lusitania by radio, but did not have the codes used to communicate with merchant ships. Captain Dow of Lusitania refused to give his own position except in code, and since he was, in any case, some distance from the positions they gave, continued to Liverpool unescorted.[38]
It seems that, in response to this new submarine threat, some alterations were made to Lusitania and her operation. She was ordered not to fly any flags in the War Zone, a number of warnings, plus advice, were sent to the ship’s commander in order to help him decide how to best protect his ship against the new threat, and it also seems that her funnels were most likely painted a dark grey to help make her less visible to enemy submarines. Clearly, there was no hope of disguising her actual identity, since her profile was so well-known, and no attempt was made to paint out the ship’s name at the prow.[39]
Captain Dow, apparently suffering from stress from operating his ship in the War Zone, and after a significant “false flag” controversy, left the ship; Cunard later explained that he was "tired and really ill."[40] He was replaced with a new commander, Captain William Thomas Turner, who had previously commanded LusitaniaMauretania, and Aquitania in the years before the war.
On 17 April 1915, Lusitania left Liverpool on her 201st transatlantic voyage, arriving in New York on 24 April. A group of German–Americans, hoping to avoid controversy if Lusitania were attacked by a U-boat, discussed their concerns with a representative of the German Embassy. The embassy decided to warn passengers before her next crossing not to sail aboard Lusitania. The Imperial German Embassy placed a warning advertisement in 50 American newspapers, including those in New York (see illustration).
NOTICE!
TRAVELLERS intending to embark on the Atlantic voyage are reminded that a state of war exists between Germany and her allies and Great Britain and her allies; that the zone of war includes the waters adjacent to the British Isles; that, in accordance with formal notice given by the Imperial German Government, vessels flying the flag of Great Britain, or any of her allies, are liable to destruction in those waters and that travellers sailing in the war zone on the ships of Great Britain or her allies do so at their own risk.
IMPERIAL GERMAN EMBASSY
Washington, D.C. 22nd April 1915
This warning was printed adjacent to an advertisement for Lusitania's return voyage. The warning led to some agitation in the press and worried the ship's passengers and crew. Lusitania departed Pier 54 in New York on 1 May 1915.

Sinking

On 7 May Lusitania was making for the port of Queenstown (now Cobh), Ireland, 70 kilometers from the Old Head of Kinsale when the liner crossed in front of U-20 at 2:10 p.m. It was sheer chance that the liner became such a convenient target, since U-20 could hardly have caught the fast vessel otherwise. Schwieger gave the order to fire, and a single torpedo was launched towards Lusitania. It hit cleanly under the bridge, blowing a hole in the side of the ship, and was then followed by a much larger secondary explosion that blew out the starboard bow.[41][42]
The ship quickly developed a severe list to starboard, and, as was typical for this period of time, the hull plates of the Lusitania were fastened with large rivets. As the lifeboats were lowered, they dragged on these rivets, which threatened to rip the boats apart. Many lifeboats overturned while loading or lowering, spilling their passengers into the sea below; those that were lowered tended to be overturned by the ship's motion when they hit the water. Some, by the negligence of some officers, crashed down onto the deck, crushing other passengers, and sliding down towards the bridge. Lusitania had 48 lifeboats, more than enough for all the crew and passengers, but only six managed to get to the water and stay afloat.[43]
Lusitania sank in 18 minutes at 2:28 pm, 11 miles (18 km) off of the Old Head of Kinsale, killing 1,198 of the 1,959 people aboard., including almost a hundred children. The bodies of many of the victims were buried at either the Lusitania port in Cobh or the Church of St. Multose in Kinsale. However, the bodies of many other victims were never recovered and remain entombed inside the wreck of the ship. The sinking turned sentiments in neutral nations against Germany and helped provoke the United States into entering the war two years later.

Wreck

The wreck of the Lusitania lies on its starboard side at an approximately 30 degree angle in 93 meters of sea water. The keel has an "unusual curvature" which may be related to a lack of strength from the loss of its superstructure.[44] The beam is reduced with the funnels missing presumably to deterioration.[44] The bow is the most prominent portion of the wreck with the sterndamaged from depth charging in the Second World War as well as the removal of three of the four propellers by Oceaneering International in 1982.[44]

[edit]Simon Lake's attempt to salvage in the 1930s

Between 1931 and 1935 an American syndicate comprising Simon Lake, one of the chief inventors of the modern submarine, and a US Navy officer, Captain H.H. Railey, negotiated a contract with the British Admiralty and other British authorities to partially salvage the Lusitania.[45] The means of salvage was unique in that a 200-foot (61 m) steel tube, five feet in diameter, which enclosed stairs, and a dive chamber at the bottom would be floated out over the Lusitania wreck and then sunk upright, with the dive chamber resting on the main deck of the Lusitania. Divers would then take the stairs down to the diver chamber and then go out of the chamber to the deck of the Lusitania. Lake's primary business goals were to salvage the purser's safe and any items of historical value.[46] It was not to be though, and in Simon Lake's own words, "... but my hands were too full" -- i.e. Lake's company was having financial difficulties at the time—and the contract with British authorities expired 31 December 1935 without any salvage work being done, even though his unique salvage tunnel had been built and tested.[47]

[edit]Recent developments

In 1967 the wreck of the Lusitania was sold by the Liverpool & London War Risks Insurance Association to former US Navy diver John Light for £1,000. Gregg Bemis became a co-owner of the wreck in 1968, and by 1982 had bought out his partners to become sole owner. He subsequently went to court in England in 1986, the US in 1995, and Ireland in 1996 to ensure that his ownership was legally in force.[48][49]
None of the jurisdictions involved objected to his ownership of the vessel but in 1995 the Irish Government declared it a heritage site under the National Monuments Act, which prohibited him from in any way interfering with it or its contents. After a protracted legal wrangle, the Supreme Court in Dublin overturned the Arts and Heritage Ministry's previous refusal to issue Bemis with a five year exploration licence in 2007, ruling that the then minister for Arts and Heritage had misconstrued the law when he refused Bemis's 2001 application. Bemis planned to dive and recover and analyse whatever artefacts and evidence could help piece together the story of what happened to the ship. He said that any items found would be given to museums following analysis. Any fine art recovered, such as the paintings by RubensRembrandt and Monet among other artists believed to have been in the possession of Sir Hugh Lane, who was believed to be carrying them in lead tubes,[50] would remain in the ownership of the Irish Government.
In late July 2008 Gregg Bemis was granted an "imaging" licence by the Department of the Environment, which allowed him to photograph and film the entire wreck, and was to allow him to produce the first high-resolution pictures of it. Bemis planned to use the data gathered to assess the wreck's deterioration and to plan a strategy for a forensic examination of the ship, which he estimated would cost $5m. Florida-based Odyssey Marine Exploration (OME) were contracted by Bemis to conduct the survey. The Department of the Environment's Underwater Archaeology Unit was to join the survey team to ensure that research would be carried out in a non-invasive manner, and a film crew from the Discovery Channel was also to be on hand.[51]
A dive team from Cork Sub Aqua Club, diving under license, discovered 15,000 rounds of the .303 (7.7×56mmR) caliber rifle ammunition transported on the Lusitania in boxes in the bow section of the ship. The find was photographed but left in situ under the terms of the license.[52] In December 2008, Gregg Bemis's dive team estimated a further four million rounds of .303 ammunition were on the ship at the time of its sinking. Mr. Bemis announced plans to commission further dives in 2009 for a full-scale forensic examination of the wreck.[53][54]
The joint American-German production, The Sinking of the Lusitania: Terror at Sea premiered on the Discovery Channel on 13 May 2007, and on BBC One in the UK on 27 May 2007.

[edit]1950s damage from depth charges

Dublin-based technical diver Des Quigley, who dived on the wreck in the 1990s with Bemis' permission, has reported that the wreck is "like Swiss cheese" and the seabed around her "is littered with unexploded hedgehog mines". Royal Navy officials have claimed they had merely been "practising" on the wreck, but others have suggested that in fact the Navy was deliberately trying to destroy evidence. Professor William Kingston of Trinity College, Dublin has said, "There's no doubt at all about it that the Royal Navy and the British government have taken very considerable steps over the years to try to prevent whatever can be found out about the Lusitania".[50]
In February 2009, the Discovery Channel TV series Treasure Quest aired an episode titled "Lusitania Revealed", in which Gregg Bemis and a team of shipwreck experts explore the wreck via remote control unmanned submersible. At one point in the show it is mentioned that Cobh locals have believed for years that in the 1950s during a two week period, the Royal Navy dropped depth charges on the wreck, greatly worsening its condition. It was stated that numerous Cobh residents on shore heard the blasting and saw navy ships hovering over the area of the wreck.[citation needed] At one point in the show an unexploded depth charge was found in the wreckage, in plain sight, clearly seen by the remote control submersible's video camera. Gregg Bemis, as well as other people on the team, believe the British Royal Navy deliberately bombed the Lusitania site to "make the wreck as unattractive as possible, to prevent further salvage" and to "prevent divers from going in and finding that there was contraband cargo". No government has ever admitted to the depth charging. The narrator says the depth charges probably crushed the upper decks of the ship, and further scattered the debris field.

1984 British legal action

In 1982 various items were recovered from the wreck and brought ashore in the United Kingdom from the cargo of the Lusitania. Complex litigation ensued, with all parties settling their differences apart from the salvors and the British Government, who asserted "droits of admiralty" over the recovered items. The judge eventually ruled in The Lusitania, [1986] QB 384, [1986] 1 All ER 1011, that the Crown has no rights over wrecks outside British territorial waters, even if the recovered items are subsequently brought into the United Kingdom.[57] The case remains the leading authority on this point of law today.
