Bruce Ismay, Managing Director of the White Star Line, and Margaret “The unsinkable Molly” Brown. There were also 285-second class and 710 3rd class passengers, and 899 crew on the ship’s manifest.

Overseeing this floating city was commodore Edward J Smith, a 25-year veteran of the White Star Line who postponed his retirement to make the voyage.

On April 14, an aura of complacency pervaded the bridge, although Titanic wireless operators Jack Philips and Harold Bride received warnings of an ice field ahead of this ship. The first of the six messages came at 13:40, but only one was formally posted on the bridge, which Commodore Smith disregarded.

As Titanic ploughed forward into the windless, moonless night at better than 22 Knots, at 23:40 lookout Frederick Fleet reported “Iceberg straight ahead.” As First Officer William Murdoch immediately acted to leave the berg to starboard, the Titanic brushed two hundred feet of her hull along a submerged spur that buckled her hull plates.

A hurried examination found that the six foremost watertight compartments had been breached; each would flood and spill successively into the next chamber until she sank. In the wake of the collision Captain Smith’s behaviour was vague, and it was only at his subordinate’s initiative that distress rockets were fired or lifeboats launched.

At 00:15 on April 15, Titanic sent her first distress call and at 00:45, she fired her first of eight distress rockets in an effort to bestir a mysterious ship (thought to be the Californian) lying 19 miles away. By 02:20, the last of the lifeboats had pulled away and the ship was perpendicular to the water, her lights still blazing. Finally she broke apart between the 3rd and 4th funnels and sank in 13,000 feet of water.

Many lifeboats left the ship partially full, and although the Cunard lines Carpathia rescued 706 survivors, there were 473 empty seats. The death toll was estimated at between 1,500 and 1,635 people. Although women and children constituted only 24% of the ship’s complement, they made up 53 % of the survivors. There were also great differences of the survivors by class (1st class - 60%, 2nd class - 42%, 3rd class - 25 % and crew - 24%).

The exact circumstances surrounding the tragedy created an orgy of press speculation. Government enquiries were convened in both Washington and London, and neither enquiry assigned explicit blame for the disaster except to the hapless Californian. However, authorities in both countries sensibly addressed the fundamental safety issues of lifeboats for all, lifeboat drills, crew training, 24 hour a day wireless operations, and the creation of the International Ice Patrol.

The story of the Titanic went through succession of interpretation in print and film, most notably Walter Lloyd’s account, “ A Night To Remember “, and a film of the same name.

It was not until 1985 that an expedition led by Dr Robert Ballad succeeded in locating and photographing the ship (the 2 sections were 1,930 feet away). In 1987, a French expedition removed artefacts from the site, despite an international outcry that the wreck should be respected as a mass grave and archaeological site. Part of James Cameroon’s Titanic (1997) was filmed on location inside the hull.
