HMHS Britannic was the third and largest Olympic-class ocean liner of the White Star Line. She was the sister ship of RMS Olympic and RMS Titanic, and was intended to enter service as a transatlantic passenger liner. She was launched just before the start of the First World War and was laid up at her builders in Belfast for many months before being put to use as a hospital ship in 1915. In that role she struck a mine off the Greek island of Kea on 21 November 1916, and sank with the loss of 30 lives.

History

Post-Titanic design changes

Following the loss of the Titanic and the subsequent inquiries, several design changes were made to the remaining Olympic-class liners. With Britannic, these changes were made before launching (Olympic was refitted on her return to Harland and Wolff). The main changes included the introduction of a double hull along the engine and boiler rooms and raising six out of the 15 watertight bulkheads up to 'B' Deck.

A more obvious external change was the fitting of large crane-like davits, each capable of holding six lifeboats. Additional lifeboats could be stored within reach of the davits on the deckhouse roof, and in an emergency the davits could even reach lifeboats on the other side of the vessel. The aim of this design was to enable all the lifeboats to be launched, even if the ship developed a list that would normally prevent lifeboats being launched on the side opposite to the list. However, several of these davits were placed abreast of funnels, defeating that purpose. Similar davits were not fitted to Olympic.

Britannic's hull was also 2 feet (0.61 m) wider than her predecessors due to the redesign after the loss of Titanic. To keep to a 21 knots (39 km/h) service speed, the shipyard installed a larger turbine rated for 18,000 horsepower (13,000 kW)-versus Olympic's and Titanic's 16,000 horsepower (12,000 kW)-to compensate for the vessel's extra width.

Although the White Star Line always denied it, most sources say that the ship was supposed to be named Gigantic.

Construction

Britannic was launched on 26 February 1914 at the Harland and Wolff shipyard in Belfast and fitting out began. She had been constructed in the same gantry slip used to build RMS Olympic. Reusing Olympic's space saved the shipyard time and money in clearing out a third slip similar in size to those used for Olympic and Titanic. In August 1914, before Britannic could commence transatlantic service between New York and Southampton, the First World War began. Immediately, all shipyards with Admiralty contracts were given top priority to use available raw materials. All civil contracts (including the Britannic) were slowed down. The military authorities requisitioned a large number of ships as armed merchant cruisers or for troop transport. The Admiralty was paying the companies for the use of their vessels but the risk of losing a ship during military operations was high. However, the big ocean liners were not taken for military use, as smaller vessels were much easier to operate. White Star decided to withdraw RMS Olympic from service until the danger had passed. RMS Olympic returned to Belfast on 3 November 1914, while work on her sister continued slowly. All this would change in 1915.

Requisitioning

The need for increased tonnage grew critical as military operations extended to the Eastern Mediterranean. In May 1915, Britannic completed mooring trials of her engines, and was prepared for emergency entrance into service with as little as four weeks notice. The same month also saw the first major loss of a civilian ocean vessel when the Cunard liner RMS Lusitania was torpedoed near the Irish coast by SM U-20.

The following month, the British Admiralty decided to use recently requisitioned passenger liners as troop transports during the Gallipoli campaign (also called the Dardanelles service). The first to sail were Cunard's RMS Mauretania and RMS Aquitania. As the Gallipoli landings proved to be disastrous and the casualties mounted, the need for large hospital ships for treatment and evacuation of wounded became evident. RMS Aquitania was diverted to hospital ship duties in August (her place as a troop transport would be taken by the RMS Olympic in September) and on 13 November 1915, Britannic was requisitioned as a hospital ship from her storage location at Belfast. Repainted white with large red crosses and a horizontal green stripe, she was renamed HMHS (His Majesty's Hospital Ship) Britannic and placed under the command of Captain Charles A. Bartlett (1868-1945).

Last voyage

After completing five successful voyages to the Middle Eastern theatre and back to the United Kingdom transporting the sick and wounded, Britannic departed Southampton for Lemnos at 14:23 on 12 November 1916, her sixth voyage to the Mediterranean Sea. The Britannic passed Gibraltar around midnight on 15 November and arrived at Naples on the morning of 17 November for her usual coaling and water refuelling stop, completing the first stage of her mission.

A storm kept the ship at Naples until Sunday afternoon, when Captain Bartlett decided to take advantage of a brief break in the weather and continue on. The seas rose once again just as Britannic left the port but by next morning the storms died and the ship passed the Strait of Messina without problems. Cape Matapan was rounded during the first hours of Tuesday, 21 November. By the morning Britannic was steaming at full speed into the Kea Channel, between Cape Sounion (the southernmost point of Attica, the prefecture that includes Athens) and the island of Kea.

Explosion

At 8:12 AM on 21 November 1916 a loud explosion shook the ship. The cause, whether it was a torpedo from an enemy submarine or a mine, was not apparent. The reaction in the dining room was immediate; doctors and nurses left instantly for their posts. Not everybody reacted the same way, as further aft the power of the explosion was less felt and many thought the ship had hit a smaller boat. Captain Bartlett and Chief Officer Hume were on the bridge at the time, and the gravity of the situation was soon evident. The first reports were frightening. The explosion had taken place on the starboard side between holds two and three, but the force of the explosion had damaged the watertight bulkhead between hold one and the forepeak. That meant that the first four watertight compartments were filling rapidly with water. To make things worse, the firemen's tunnel connecting the firemen's quarters in the bow with boiler room six had also been seriously damaged and water was flowing into that boiler room.

Bartlett ordered the watertight doors closed, sent a distress signal and ordered the crew to prepare the lifeboats. Unfortunately, another surprise was waiting. Along with the damaged watertight door of the firemen's tunnel, the watertight door between boiler rooms six and five also failed to close properly for an unknown reason. Now water was flowing further aft into boiler room five. The Britannic had reached her flooding limit. She could stay afloat (motionless) with her first six watertight compartments flooded and had five watertight bulkheads rising all the way up to B-deck. Those measures were taken after the Titanic disaster (Titanic could float with her first four compartments flooded but the bulkheads only rose as high as E-deck). Luckily, the next crucial bulkhead between boiler rooms five and four and its door were undamaged and should have guaranteed the survival of the ship. However, there was something else that probably sealed Britannic's fate: the open portholes of the lower decks. The nurses had opened most of those portholes to ventilate the wards. As the ship's list increased, water reached this level and began to enter aft from the bulkhead between boiler rooms five and four. With more than six compartments flooded, the Britannic could not stay afloat.

Evacuation

On the bridge, Captain Bartlett was trying to save his vessel. Only two minutes after the blast, boiler rooms five and six had to be evacuated. In about ten minutes the Britannic was roughly in the same condition the Titanic was one hour after the collision with the iceberg. Fifteen minutes after the ship was struck the open portholes on E-deck were underwater. Water also entered the ship's aft section from the bulkhead between boiler rooms five and four. The Britannic quickly developed a serious list to starboard. To his right Bartlett saw the shores of Kea, about three miles away. He decided to make a last desperate effort to beach the ship. This was not an easy task because of the combined effect of the list and the weight of the rudder. The steering gear was unable to respond properly but by using the propellers alone (giving more power to the port shaft) Britannic slowly started to turn right.

Simultaneously, on the boat deck the crewmembers were preparing the lifeboats. Some of the boats were immediately rushed by a group of stewards and some sailors, who had started to panic. An unknown officer kept his nerve and persuaded his sailors to get out and stand by their positions near the boat stations. He decided to leave the stewards on the lifeboats as they were responsible for starting the panic and he did not want them in his way during the evacuation. However, he left one of the crew with them in order to take charge of the lifeboat after leaving the ship. After this episode, all the sailors under his command remained at their posts until the last moment. As no RAMC personnel were near this boat station at that time, the Officer started to lower the boats, but when he saw that the ship's engines were still running, he stopped them within six feet (2 m) of the water and waited for orders from the bridge. The occupants of the lifeboats did not take this decision very well and started cursing. Shortly after this, orders finally arrived: no lifeboats should be launched, as the Captain had decided to beach the Britannic.

Assistant Commander Harry William Dyke was making the arrangements for the lowering of the lifeboats from the aft davits of the starboard boat deck when he spotted a group of firemen who had taken a lifeboat from the poop deck without authorisation and had not filled it to maximum capacity. Dyke ordered them to pick up some of the men who had already jumped into the water.

At 08:30, two lifeboats from the boat station assigned to Third Officer David Laws were lowered without his knowledge through the use of the automatic release gear. Those two lifeboats dropped some 6 feet into the water and hit the water violently. The two lifeboats soon drifted into the still-turning propellers, which were almost out of the water by now. As they reached the turning blades, both lifeboats, together with their occupants, were torn to pieces. Word of the carnage arrived on the bridge, and Captain Bartlett, seeing that water was entering more rapidly as Britannic was moving and that there was a risk of more victims, gave the order to stop the engines. The propellers stopped turning the moment a third lifeboat was about to be reduced to splinters. RAMC occupants of this boat pushed against the blades and got away from them safely.

Final moments

The Captain officially ordered the crew to lower the boats and at 08:35, he gave the order to abandon ship. The forward set of port side davits soon became useless. The unknown officer had already launched his two lifeboats and managed to launch rapidly one more boat from the after set of portside davits. He then started to prepare the motor launch when First Officer Oliver came with orders from the Captain. Bartlett had ordered Oliver to get in the motor launch and use its speed to pick up survivors from the smashed lifeboats. Then he was to take charge of the small fleet of lifeboats formed around the sinking Britannic. After launching the motor launch with Oliver, the unknown officer filled another lifeboat with seventy-five men and launched it with great difficulty because the port side was now very high from the surface due to the list to starboard. By 08:45, the list to starboard was so great that no davits were operable. The unknown officer with six sailors decided to move to mid-ship on the boat deck to throw overboard-collapsible rafts and deck chairs from the starboard side. About thirty RAMC personnel who were still left on the ship followed them. As he was about to order these men to jump then give his final report to the Captain, the unknown officer spotted Sixth officer Welch and a few sailors near one of the smaller lifeboats on the starboard side. They were trying to lift the boat but they had not enough men. Quickly, the unknown officer ordered his group of forty men to assist the Sixth officer. Together they managed to lift it, load it with men, then launch it safely.

At 09:00, Bartlett sounded one last blast on the whistle then just walked into the water, which had already reached the bridge. He swam to a collapsible boat and began to co-ordinate the rescue operations. The whistle blow was the final signal for the ship's engineers (commanded by Chief Engineer Robert Fleming) who, like their heroic colleagues on the Titanic, had remained at their posts until the last possible moment. They escaped via the staircase into funnel #4, which ventilated the engine room.

The Britannic rolled over onto her starboard side and the funnels began collapsing. Violet Jessop (who was also one of the survivors of Britannic's sister-ship Titanic, as well as the third sister, Olympic, when she collided with HMS Hawke), described the last seconds: "She dipped her head a little, then a little lower and still lower. All the deck machinery fell into the sea like a child's toys. Then she took a fearful plunge, her stern rearing hundreds of feet into the air until with a final roar, she disappeared into the depths, the noise of her going resounding through the water with undreamt-of violence....” It was 09:07, only fifty-five minutes after the explosion. The Britannic was the largest ship lost during the First World War.

Rescue

The first to arrive on the scene were the Greek fishermen from Kea on their Cax�que, who picked up many men from the water. One of them, Francesco Psilas, was later paid �4 by the Admiralty for his services. At 10:00, HMS Scourge sighted the first lifeboats and ten minutes later stopped and picked up 339 survivors. HMS Heroic had arrived some minutes earlier and picked up 494. Some 150 had made it to Korissia (a community on Kea), where surviving doctors and nurses from the Britannic were trying to save the horribly mutilated men, using aprons and pieces of lifebelts to make dressings. A little barren quayside served as their operating room. Although the motor launches were quick to transport the wounded to Korissia, the first lifeboat arrived there some two hours later due to the strong current and their heavy load. It was the lifeboat of Sixth Officer Welch and the unknown Officer. The latter was able to speak some French and managed to talk with one of the local villagers, obtaining some bottles of brandy and some bread for the injured.

The inhabitants of Korissia were deeply moved by the suffering of the wounded. They offered all possible assistance to the survivors and hosted many of them in their houses while waiting for the rescue ships. Violet Jessop approached one of the wounded. "An elderly man, in an RAMC uniform with a row of ribbons on his breast, lay motionless on the ground. Part of his thigh was gone and one foot missing; the grey-green hue of his face contrasted with his fine physique. I took his hand and looked at him. After a long time, he opened his eyes and said: 'I'm dying'. There seemed nothing to disprove him yet I involuntarily replied: 'No, you are not going to die, because I've just been praying for you to live'. He gave me a beautiful smile . . . That man lived and sang jolly songs for us on Christmas Day.”

The Scourge and Heroic had no deck space for more survivors and they left for Piraeus signalling the presence of those left at Korissia. Luckily, HMS Foxhound arrived at 11:45 and, after sweeping the area, anchored in the small port at 13:00 to offer medical assistance and take onboard the remaining survivors. At 14:00 arrived the light cruiser HMS Foresight. The Foxhound departed for Piraeus at 14:15 while the Foresight remained to arrange the burial on Kea of Sergeant W. Sharpe, who had died of his injuries. Another two men died on the Heroic and one on the French tug Goliath. The three were buried with military honours in the British cemetery at Piraeus. The last fatality was G. Honeycott, who died at the Russian Hospital at Piraeus shortly after the funerals.

1,036 people were saved. Thirty men lost their lives in the disaster but only five were buried. The others were left in the water and their memory is honoured in memorials in Thessaloniki and London. Another twenty-four men were injured. The ship carried no patients. The survivors were hosted in the warships that were anchored at the port of Piraeus. However, the nurses and the officers were hosted in separate hotels at Phaleron. Many Greek citizens and officials attended the funerals.

Wreck

The wreck of HMHS Britannic is at 37�42′05″N 24�17′02″E / 37.70139�N 24.28389�E / 37.70139; 24.28389 in about 400 ft (120 m) of water. It was first discovered and explored by Jacques Cousteau in 1975. The giant liner lies on her starboard side hiding the zone of impact with the mine. There is a huge hole just beneath the forward well deck. The bow is attached to the rest of the hull only by some pieces of the B-deck. This is the result of the massive explosion that destroyed the entire part of the keel between bulkheads two and three and of the force of impact with the seabed. The bow is heavily deformed as the ship hit the seabed before the total length of the 882 feet 9 inches (269 m) liner was completely submerged, as she sank in a depth of only 400 feet of water. Despite this, the crew's quarters in the forecastle were found to be in good shape with many details still visible. The holds were found empty. The forecastle machinery and the two cargo cranes in the forward well deck are still there and are well preserved. The foremast is bent and lies on the sea floor near the wreck with the crow's nest still attached on it. The bell was not found. Funnel #1 was found a few metres from the Boat Deck. The other three funnels were found in the debris field (located off the stern). The wreck lies in shallow enough water that scuba divers trained in technical diving can explore it, but it is listed as a British war grave and any expedition must be approved by both the British and Greek governments.

In mid-1995, during an expedition filmed by NOVA, Dr. Robert Ballard visited the wreck, using advanced side-scan sonar. Images were obtained from remotely controlled vehicles, but the wreck was not penetrated. Ballard succeeded in locating all the ship's funnels, which proved to be in surprisingly good condition. Attempts to find mine anchors failed.

In August 1996, the wreck of HMHS Britannic became available for sale and was bought by maritime historian Simon Mills who has written two books about the ship: Britannic-The Last Titan, and Hostage To Fortune. When Simon Mills was asked if he had all the money and support needed, what would his ideal vision be for the wreck of Britannic be, he replied: "That's simple-to leave it as it is!"

In November 1997, an international team of divers led by Kevin Gurr used open-circuit trimix diving techniques to visit and film the wreck in the newly available DV digital video format. Kevin Gurr, Alan Wright, John Thornton, Dan Burton, Uffe Eriksson, Ingemar Lundgren, Richard Lundgren, Dave Thompson, Alexander Sotiriou, Kirk Kavalaris, Kevin Denlay, Tristan Cope, Miria Denlay, Gary Sharp, Ian Fuller, and Manthos Sotiriou participated in the project. Vangelis Sotiriou provided general support.

In September 1998, a team of divers led by Nick Hope made a major expedition to the wreck. Many of the divers who participated in 'Britannic 98' were members of the deep wreck-diving team, 'The Starfish Enterprise'. Using diver propulsion vehicles (DPVs), the team made more man-dives to the wreck and produced more images than ever before, including video of four telegraphs, a helm and a telemotor on the captain's bridge. John Chatterton became the first diver to visit Britannic using a closed-circuit rebreather, but his efforts to penetrate the firemen's tunnel using it were hampered by its poor reliability. Christina Campbell became the first woman to dive the wreck. The expedition was regarded as one of the biggest wreck diving projects ever undertaken. Time magazine published images shot during the expedition. The expedition inspired many others to explore the wreck, including Carl Spencer, who mounted his own expedition in 2003.

The principal divers were: Nick Hope (UK), Leigh Bishop (UK), John Chatterton (US), Christina Campbell (UK), Geraint Ffoulkes-Jones (UK), Chris Hutchison (UK), Bob Hughes (UK), Innes McCartney (UK), Jamie Powell (UK), Rob Royle (UK), Dave Wilkins (UK), John Yurga (US). The support team, many of whom also dived the wreck: Greg Buxton (UK), Dan Crowell (US), Kevin Emans (UK), Hagen Martin (UK), Greg Mossfeldt (Canada), Kostas Nizamis (Greece), Derek Palmer (UK), Marinos Pittas (Greece), Jen Samulski (US), Gregoris Theodoris (Greece), Andrea Webb (UK), Becky Williams (UK).

In 1999, GUE, divers acclimated to cave diving and ocean discovery, led the first dive expedition to include extensive penetration into Britannic. Video of the expedition was broadcast by National Geographic, BBC, the History Channel, and the Discovery Channel.

In 2003, an expedition led by Carl Spencer used advanced diving technology to send scuba divers into the wreck. Spencer's expedition is regarded as the expedition that answered the important questions, why the ship sank and what made her sink so fast. Their most significant finding was that several watertight doors were open. It has been suggested that this was because the mine strike coincided with the change of watches. Alternatively, the explosion may have distorted the doorframes. A number of mine anchors were located off the wreck by Sonar expert Bill Smith, confirming the German records of U-73 that Britannic was sunk by a single mine and the damage was compounded by open portholes and watertight doors. Spencer's expedition was broadcast extensively across the world for many years by National Geographic and the UK's Channel 5.

In 2006, an expedition, funded and filmed by the History Channel, brought together thirteen of the world's best wreck divers to help determine what caused the quick sinking of the Britannic. Setting sail on 17 September in a diving boat converted from a fishing boat for this mission, the crew dived and explored the sunken ship. After days of preparation, the wreck was explored by divers John Chatterton and Richie Kohler. However, time was cut short when silt was kicked-up, causing zero visibility conditions, and the two divers narrowly escaped with their lives. John Chatterton's rebreather famously failed whilst he was still deep inside the wreck. One last dive was to be attempted on Britannic's boiler room, but it was discovered that photographing this far inside the wreck would lead to breaking the rules of a permit issued by the Ephorate of Underwater Antiquities, a department within the Greek Ministry of Culture. Due partly to a barrier in languages, a last minute plea was turned down by the department. The expedition was unable to determine the cause of the rapid sinking, but hours of footage were filmed and important data was documented. Underwater Antiquities later recognized the importance of this mission and has since extended an invitation to revisit the wreck under less stringent rules.

During this expedition, Chatterton and Kohler found a bulb shape in her expansion joint. This proved that her design was changed following the loss of Titanic.

On 24 May 2009, a diver, Carl Spencer, 39, died in Greece from a suspected case of decompression sickness, commonly known as the bends, which is caused by surfacing too quickly from a dive, while filming the wreck of HMHS Britannic for National Geographic. He is reported to have "begun convulsing" at depth which is a symptom of oxygen poisoning. He was diving with an Ouroboros rebreather. Carl Spencer, from Burton-on-Trent, Staffordshire, was part of a 17-member crew. Spencer, father-of-two, was an experienced mixed gas and closed circuit rebreather diver who had been on three previous missions to film the Britannic. He was in the team during the exploration of the Titanic wreckage as part of a Discovery Channel expedition led by filmmaker James Cameron, who directed the blockbuster Titanic.

Pipe organ

A Welte Philharmonic Organ was planned to be installed onboard the Britannic. Due to the outbreak of the First World War, the instrument never made its way to Belfast.

During the restoration of the Welte-Organ now in the Swiss National Museum in Seewen, the restorers detected in April 2007 that the main parts of the instruments were signed by the German organ builders with "Britanik". A photo of a drawing in a company prospectus, found in the Welte-legacy in the Augustiner Museum in Freiburg, proved that this was the organ for the Britannic.

Film adaptation

The sinking of the Britannic was dramatised in a 2000 film of the same name that featured Edward Atterton, Amanda Ryan and Jacqueline Bisset. The film took several liberties with the events aboard the vessel, depicting the sinking as being caused by an onboard saboteur rather than a naval mine.
