Question: Herbert James Haddockwas captain of British transatlantic ocean liner which gained what nickname?

full_context: Document 1: RMS Titanic: RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history. The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line. The Titanic was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, her architect, died in the disaster.
Document 2: RMS Homeric (1913): RMS "Homeric", originally launched as "Columbus", was built for Norddeutscher Lloyd and launched in 1913 at the F. Schichau yard in Danzig. "Columbus" was ceded to Great Britain in 1919 as part of German war reparations. She was sold to White Star Line in 1920, which named her "Homeric". Her sister ship "Hindenburg" retained her German ownership and was renamed "Columbus". "Homeric" was operated by White Star from 1922 to 1935.
Document 3: RMS Olympic: RMS "Olympic" ( ) was a British transatlantic ocean liner, the lead ship of the White Star Line's trio of "Olympic"-class liners. Unlike her younger sister ships, "Olympic" had a long career, spanning 24 years from 1911 to 1935. This included service as a troopship during the First World War, which gained her the nickname "Old Reliable". "Olympic" returned to civilian service after the war and served successfully as an ocean liner throughout the 1920s and into the first half of the 1930s, although increased competition, and the slump in trade during the Great Depression after 1930, made her operation increasingly unprofitable.
Document 4: Joseph Henderson (pilot): Captain Joseph Henderson (September 9, 1826 - October 7, 1890) was an early American harbor pilot who guided large vessels in and out of the New York harbor. He was a legendary figure in New York during the 1880s, well known for being one of the oldest and wealthiest of the Sandy Hook Pilots, which operated in what is now the Port of New York and New Jersey. He was recognized to all the large steamship owners as one of the most experienced and trustworthy New York pilots.
Document 5: Titanic Belfast: Titanic Belfast is a visitor attraction and a monument to Belfast's maritime heritage on the site of the former Harland & Wolff shipyard in the city's Titanic Quarter where the RMS "Titanic" was built. It tells the stories of the ill-fated "Titanic", which hit an iceberg and sank during her maiden voyage in 1912, and her sister ships RMS "Olympic" and HMHS "Britannic". The building contains more than 12000 sqm of floor space, most of which is occupied by a series of galleries, plus private function rooms and community facilities.
Document 6: The captain goes down with the ship: "The captain goes down with the ship" is an idiom and maritime tradition that a sea captain holds ultimate responsibility for both his ship and everyone embarked on it, and that in an emergency, he will either save them or die trying. Although often connected to the sinking of the RMS "Titanic" in 1912 and its captain, Edward J. Smith, the phrase precedes "Titanic" by at least 11 years. In most instances the captain of the ship forgoes his own rapid departure of a ship in distress, and concentrates instead on saving other people. It often results in either the death or belated rescue of the captain as the last person on board.
Document 7: Oceanic (unfinished ship): The RMMV (Royal Mail Motor Vessel) Oceanic was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line. The ship was to have been the first 1000 ft -long ocean liner. It was intended to be the largest ocean liner for the White Star Line, thus it would have been larger than the earlier White Star giants, "Olympic", "Titanic", "Britannic", and "Majestic".
Document 8: RMS Queen Mary: RMS "Queen Mary" is a retired ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard Line (known as Cunard-White Star Line when the vessel entered service). Built by John Brown & Company in Clydebank, Scotland, "Queen Mary", along with  , were built as part of Cunard's planned two-ship weekly express service between Southampton, Cherbourg and New York. The two ships were a British response to the express superliners built by German, Italian and French companies in the late 1920s and early 1930s. "Queen Mary" was the flagship of the Cunard Line from May 1936 until October 1946 when she was replaced in that role by "Queen Elizabeth".
Document 9: Olympic-class ocean liner: The "Olympic"-class ocean liners were a trio of British ocean liners built by the Harland & Wolff shipyard for the White Star Line during the early 20th century. They were "Olympic" (1911), "Titanic" (1912), and "Britannic" (1915). All three were designed to be the largest and most luxurious passenger ships in the world, designed to give White Star an advantage in the transatlantic passenger trade. Two were lost early in their careers: "Titanic" sank in 1912 on its maiden voyage, after hitting an iceberg in the North Atlantic Ocean, and "Britannic" in 1916, after hitting a mine laid by the minelayer submarine "U-73" in a barrier off Kea in the Aegean Sea during World War I. "Olympic", the lead vessel, had a career spanning 24 years and was retired in 1934 and sold for scrapping in 1935.
Document 10: RMS Republic (1903): RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision six years later while sailing for the White Star Line. A CQD distress call was issued on the new Marconi radio device, the first recorded, resulting in the saving of around 1500 lives. Known as the "Millionaires' Ship" on account of the number of well-known and immensely rich Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service.
Document 11: Herbert Richmond: Admiral Sir Herbert William Richmond {'1': ", '2': ", '3': ", '4': "} (15 September 1871 – 15 December 1946) was a prominent Royal Navy officer, described as "perhaps the most brilliant naval officer of his generation." He was also a top naval historian, known as the "British Mahan", the leader of the British Royal Navy's intellectual revolution that stressed continuing education especially in naval history as essential to the formation of naval strategy. After serving as a "gadfly" to the British Admiralty, his constructive criticisms causing him to be "denied the role in the formation of policy and the reformations of naval education which his talents warranted", he served as the first Vere Harmsworth Professor of Imperial and Naval History at Cambridge University in 1934-1936, and Master of Downing College, Cambridge in 1934-1946.
Document 12: J. Bruce Ismay: Joseph Bruce Ismay ( ; 12 December 1862 – 17 October 1937) was an English businessman who served as chairman and managing director of the White Star Line. In 1912 he came to international attention as the highest-ranking White Star official to survive the sinking of the company's brand new flagship RMS "Titanic", for which he was subject to severe criticism.
Document 13: HMS Royal Oak (1892): HMS "Royal Oak" was one of seven "Royal Sovereign"-class pre-dreadnought battleships built for the Royal Navy during the 1890s. Upon her completion in 1894, she was initially placed in reserve until mobilised in 1896 for service with the Flying Squadron. After returning briefly to reserve, the ship was assigned the following year to the Mediterranean Fleet. "Royal Oak" remained there until 1902 when she returned home; after a refit, the ship was assigned to the Home Fleet, where she served as the flagship of the fleet's second-in-command in 1904–05. "Royal Oak" was then reduced to reserve until she was taken out of service in 1911. The ship was sold for scrap in early 1914.
Document 14: Herbert Haddock: Herbert James Haddock, CB RNR (27 January 1861 – 4 October 1946) was an English naval reserve officer and ship's captain, and was captain of the RMS "Olympic" at the time of the sinking of the "Titanic". He was the first person to captain "Titanic," overseeing the ship at Belfast while her delivery-trip crew was assembling there from 25 to 31 March 1912.
Document 15: SS Nomadic (1911): SS "Nomadic" is a former tender of the White Star Line, launched on 25 April 1911 in Belfast now on display in Belfast's Titanic Quarter. She was built to transfer passengers and mail to and from RMS "Olympic" and RMS "Titanic", and is the only White Star Line vessel in existence today.
