Work had only just been started on keel 433, the last and largest of the three Olympic
class ships Britannic when construction was halted to await the outcome of the inquiry into
the loss of the Titanic. When work was restarted many changes to the design were
incorporated in the final plans. These included a double skin which increased her beam by
two feet, the double bottom, itself normally five feet deep was increased to six feet. the
space between the inner and outer bottoms was seperated into compartments by six huge
longitudinal steel girders to minimise flooding in case of rupture. Water tight bulkheads for
the most part had extended onlu as high as the bottom of E deck in the forward part of the
ship and D deck in the rear, The Britannic had five extended to B deck and the other
eleven to E deck. It no longer seemed to matter if the bulkheads and thier heavy doors
bisected first class compartments. Four rows of rivets on plating where stress would be
greatest, giant sized lifeboat davits, and a name change from Gigantic to Britannic. These
modifications made her the largest in gross tonnage of the three at 48,158 tons. As a
hospital ship she was about 5% larger and probably would have been about 50,000 tons
(about 10% larger) when fitted as a commercial liner. Most of this was due to increased
compartmentalisation, the giant sized lifeboat davits, somewhat heavier construction
throughout and a whole list of safety gear and redundant systems. The White Star Line
became obsessed with safety following the disaster of her sister ship. Tonnage is based on
enclosed space not weight per se, as the term implies. 

She was launched on February 26th 1914 and White Star announced she would commence
service between Southampton and New York in the spring of 1915. Outbreak of World War
One was to change this. On November 13th 1915 she was requisitioned by the admiralty
and officially completed as a hospital ship. Her nearly completed interiors were converted
into dormitories and operating rooms. On December 12th 1915 she was ready for war
service. 

She arrived in Liverpool on December 12th, 1915 under heavy armed escort. She was
outfitted for her duties as a hospital ship with 2034 berths and 1035 cots for casualties. A
medical staff of 52 officers, 101 nurses, 336 orderlies, and a crew of 675 men and women.
The ship was under the command of Captain Charles A. Bartlett. 

He started his career with the White Star Line in 1874 and rose through various positions
serving on such ships as Celtic, Teutonic, Oceanic and Georgic. He earned his Masters
Certificate in 1903. As a Master, he commanded such ships as the Germanic, Cedric, and
for a brief period the ill fated Republic. His daughter recalls that he was well liked by his
passengers but not always by the White Star Management, mainly because of his
excessive concern for safety over speed. 

The Britannic was commissioned "His Majesty's Hospital Ship" on December 12, 1915
and departed Liverpool for her maiden voyage on December 23, 1915. She was bound for
Mudros on the isle of Lemnos. She was joining the Mauretania, Aquitania, and her sister,
Olympic, in the "Dardanelles Service." Joined later by the Statendam the five ships
together were capable of carrying 17,000 sick and wounded or 33,000 troops. 

Because of their size, the five ships including Britannic would have to anchor in very deep
water and rely on as many as eight smaller ships to ferry the wounded and ill from the
battlefront docks to the ships. 

Christmas was celebrated on the Britannic as she sailed for her coaling port of Naples,
arriving on 28th December, 1915. Once coaled, she departed on 29th December bound for
Mudros in the Agean Sea. She spent four days at Mudros seeing the start of 1916 and
taking on 3,300 wounded and sick military personnel. 

The Britannic returned to Southampton on January 9th, 1916 where her patients were
transferred to waiting trains for transportation to hospitals in London. The second voyage
was shorter as she only sailed as far as Naples where she took on wounded and returned to
Southampton on February 9, 1916. The third voyage was just as uneventful. She spent four
weeks as a floating hospital off the Isle of Wight, Cowes. Following this service, the
Britannic returned to Belfast on June 6th, 1916 and was released from war service. 

Harland and Wolff started refitting her for Royal Mail and Passenger service once again,
but work was halted when the Admiralty recalled her to war service and she once again
returned to Southampton on August 28th, 1916. 

Britannic began her fourth voyage on September 24th, 1916 with members of the
Voluntary Aid Detachment on board. These members of VAD were to be trans-shipped at
Mudros, bound for Malta. Following her coaling stop at Naples, the ship arrived at Mudros
on October 3rd, 1916 where VAD members were transferred to His Majesty's Hospital
Ship Galeka. The Britannic was detained at Mudros while officials investigated the
possible cause of food poisoning which had stricken some of the staff. The ship returned to
Southampton on October 11, 1916. 

Voyage number five was the Southampton, Naples, Mudros trip. On the last day of the
fifth voyage she encountered heavy seas and storms. She finally made it to Southampton
and over 3000 wounded were transferred to waiting trains. The Aquitania had suffered
damage in the same storms and was laid up for repairs, and because of this Britannic was
ordered to start her sixth voyage after only four days in port. 

The Britannic departed Southampton on Sunday 12th November 1916. She was due to
leave at 10:00 am but actually left the docks at noon. The weather was calm. She carried
no "passengers". Friday November 17th 1916 she arrived at Naples, for coaling and was
to depart on Saturday but a fierce storm set in a delayed the departure. 

A perfect day, Tuesday November 21, 1916 she was steaming through the Kea Channel in
the Aegean during World War One. Shortly after 8:00am she was struck by a tremendous
explosion and quickly began to sink by the bow. Captain Bartlett tried unsuccessfully to
beach her on Kea Island but in 55 minutes, Britain's largest liner had gone, and not quite a
year from trials to sinking of only 351 days. The explosion apparently occurred at the
watertight bulkhead between holds 2 and 3, and the bulkhead separating holds 2 and 1
were also damaged. At the same time, boiler rooms 5 and 6 began taking water. This was
roughly the same damage as that sustained by her sister the Titanic four and a half years
earlier. 

She lies on her side in only 350 feet of water. So shallow, that the bow hit bottom before
she totally sank and with the weight, the entire bow is now bent. She was discovered in
1976 on an Underwater Exploration by Jacques Cousteau. She is largely intact except for
the massive hole in her forward bow. The hull below the Shelter Deck is completely blown
away between holds 2 and 3. The hull sections of the keel are simply missing for a distance
of about 60 to 70 feet. The port side hull plates are bent outward, indicating a large
explosion from within, probably from ignition of coal dust in the reserve bunker. 

Her captain Charles Bartlett was the last to leave the ship and only 30 people died from
over 1100 on board at the time. Most of these deaths occurred as the ship remained under
way when two lifeboats were launched prematurely and were sucked into the still turning
propellers. As a strange footnote to the tragedy, one of the crew members, Violet Jessup,
had been a member of the Titanic crew and she survived both sinking's and was abord the
Olympic when it had the collision with HMS Hawke. 

Even with all her modifications she sank in only fifty five minutes, with similar damage to
her sister. The Titanic without the modifications managed to stay afloat three times longer.
I believe two possibilities, one, that due to the very large hole in her side she took on water
at a much faster rate than the "dent" damage her sister suffered. Secondly, the watertight
doors may not have been closed, this would have been extremely negligent for a ship
sailing in a combat zone and is difficult to believe. Recent reports state that the doors were
open due to a shift change at 8:00am, as this made it easier for the crew to travel. Why she
sank has never been totally resolved, some say she was torpedoed but it seems more
likely that she struck a mine. She is the largest liner on the ocean floor today. 

The easiest way to distinguish her from her two sisters are by the out-sized lifeboat davits,
and most photos of her show a white hull with three red crosses and a green hull band on
her side, designating her as a hospital ship. HMHS Britannic was never to carry a fare
paying passenger.
