During the first World War he commanded a dummy fleet of wooden dreadnoughts and battle cruisers. As commodore he served with the Britanic, [sic] German, [sic] Cedric, Oceanic and Olympic.
Captain Haddock, a former aide de camp to the King, was made a Companion of the Order of the Bath in 1902. In 1893 he married Mabel Bouchette of Quebec, who died in 1935.
In April 1912, Captain Haddock was in command of the White Star liner Olympic en route from New York to Southampton when her sister ship, the Titanic, westward bound, while making her maiden voyage, struck an iceberg and sank in one of the greatest ocean disasters. The Olympic was 500 miles away and hastened to the rescue but resumed her course when 100 miles from the scene of the sinking when informed there was nothing to be gained by continuing to that point. For a time the Olympic wireless room acted as a sort of clearing housefor radio messages relating to the accident.
Captain Haddock was an exceedingly modest man who hated to see his name in the newspapers.
