RMS Titanic is sailing west around 600 miles south east of Newfoundland, Canada. It's the 5th night of the voyage, which has been uneventful since a near collision with the New York in Southampton docks. /1

The air is still and the water absolute dead calm. Cold but motionless, described as being like a 'mill pond'. This means no breaking waves around the base of the floating iceberg. /2

It's Sunday night and most of the 1,400 passengers are either in bed or having last drinks in the various bars and lounges. The 885 crew are either on shift or likewise trying to get some sleep in their quarters near the boiler rooms. /3

The maiden voyage, already overshadowed by the recent success snd even more recent accidents involving her sister, Olympic, was a bit of a damp squib, spoilt by coal workers strikes and high profile passenger cancellations. /4

The iceberg is sighted by helmsman Frederick Fleet high in the crows nest on the fore mast. He rings the bell to inform the bridge /5

Officer Moody takes the call and orders the engines to go into reverse, and for the ship to turn abruptly to starboard to avoid the ice. It doesn't work. The shop glances the iceberg. /5

The iceberg doesn't penetrate the steel of the hull. Rather, it pushes apart where the plates meet, popping rivets like an overstrained shirt pops buttons. Water gushes into these gaps immediately. /7

Captain Smith is on the bridge. Watertight doors have already been closed by Officer Murdoch and passengers are playing football with some of the ice that sheared off the berg onto the deck. /8

Crew head below decks to check out the damage as thd ship glides to a halt skmd miles beyond the iceberg, which some passengers saw through the portholes and screen windows. /9

Air is hissing loudly from pipes and openings at the bow of the ship. Crew realise this means flooding below decks, displacing the air. /10

J Bruce Ismay, manager of the White Star Line appears on the bridge demanding information. Wireless room continues its ordinary work. /11

The water is already 14ft above the keel of the ship. Five watertight compartments have been holed, which is one more than it can withstand. As Thomas Andrews absmd the ship's carpenter will announce at midnight, there is nothing that can save the ship. /12 #Titanic108

At this point, other than perhaps noticing a slight jar and the silence as the engines stop, passengers are none the wiser and continue what they were doing. Some reports of fragments of ice put into drinks by caddish sorts. #Titanic108 /13

Otherwise life on the ship is normal, apart from a buzz of activity around the bridge and bow, which most passengers would be totally unaware of. All the time icy seawater is filling up compartments on the lower decks. /14 #Titanic108

The cargo hold contains very little of note, despite persistent rumours since. There is no cursed mummy or priceless jewels. There are a few motorcars and some art, as well as a fancy bejeweled copy of the Rubaiyat of Omar Khayyam. Most of this is pretty much already soaked. /15

Thomas Andrews, the designer of the three sisters (the un-named third would become 'Britannic' and would sink in the Mediterranean during WW1) tells Captain Smith at midnight that the ship will definitely sink. Nothing can be done. /16 #Titanic108

Smith orders that the lifeboats should be uncovered and prepared for evacuation. None would actually leave for a further 40 minutes. The ship has two hours and fifteen minutes left. /17 #Titanic108

Water is already flooding Third Class rooms deep down on G Deck. We can assume that third class passengers housed in the bow would be the first passengers to realise what is happening. But they will struggle to reach the lifeboats on the boat deck, 7 floors up. /18 #Titanic108

Captain Smith finally gets round to instructing the wireless operators to contact nearby ships for assistance. They don't yet use the SOS message. Water has flooded the squash courts.

The band begins to play. They will continue until ten minutes before the end. /19 #Titanic108

The Carpathia receives the CQD distress call and quickly leaps into action. Trouble is it's miles away and will take about 4-5 hours to get there. The ship will sink in two hours and five minutes. /20 #Titanic108

Other ships are in the vicinity, including the Olympic, but none are close enough to get to the Titanic in time apart from the Californian, which famously doesn't respond to the distress signal.

Lifeboats still being prepared. Band still playing. (2.00:00 remain) /21 #Titanic108

Most passengers are beginning to realise somethings up, either due to stewards knocking their doors or the fact their bedding is getting wet. But it's a big job to herd these people up onto the freezing cold boat deck at midnight. (1.58:00) /22 #Titanic108

Water reaches E deck, at the bow at least. This is an issue because of the long, wide crew corridor known as 'Scotland Road' - water just gushes along it. The ship is starting to list slightly and is down at the bow a little. (1.54:00)/23 #Titanic108

Passengers are beginning to congregate on the boat deck, listening to the lively tunes from Wallace Hartley's band. It's really cold and there's not much organisation. (1.49:00) /24 #Titanic108

Lifeboat number 7 is starting to fill with a few reluctant women and children. The boats can carry 65 passengers each, but it's not clear that the crew knows this. There are 16 regular lifeboats and 4 'collapsibles' situated on the roof of the bridge. (1.46:00) /25 #Titanic108

Lifeboat 7 starts to be lowered down into the Atlantic. It has 28 people on board, so nearly 40 under capacity. The boat is settling by the head now, noticeably down. (1.40:00) /26 #Titanic108

Lifeboat 5 is lowered. It's about as poorly filled as 7. The iceberg was struck an hour ago. The ship has less than 100 minutes left on the surface. (1.37:00) /27 #Titanic108

Officer Boxhall fires the first distress rocket, which livens up the evening considerably. It is assumed some passengers probably did think they were a firework display but we don't know for sure. (1.35:00) /28 #Titanic108

Most passengers on the boat deck take shelter in the first class lounge and grand staircase, as it's so icy cold. The water is even colder. Plenty of people are still assuming it's just a minor thing or even a drill. (1.32:00) /29 #Titanic108

Third class passengers are having terrible difficulty getting to the boat deck, as it is normally off limits to them. Some get lost in the maze of corridors, or are blocked behind locked doors designed to segregate the classes. (1.30:00) /30 #Titanic108

Lifeboat 3 is lowered, contained half a full complement of passengers. People are not interested in leaving the seemingly sturdy and safe liner for flimsy little rowboats on the open ocean. (1.25:00) /31 #Titanic108

Lifeboat 8 is lowered by Officer Lightoller. Again, half full. The wireless operators get in touch with the US mainland, so suddenly the world is beginning to be aware of what's happening. The grand staircase begins to flood. At the bottom, obv. (1.20:00) /32 #Titanic108

Lifeboat 1, a slightly smaller vessel with a capacity of 40, is lowered with only 12 people aboard. Considerable listing to port now making it harder for starboard lifeboats to be filled. The band plays on. (1.15:00) /33 #Titanic108

It is beginning to get more apparent that the situation is serious. The ship is listing badly, and down at the bow. Rockets are launched at 5 minute intervals and occasionally the lights flicker. There is no moon tonight. (1.12:00) /34 #Titanic108

Lifeboat 6, again half full, is lowered. Water is up to the forecastle now. Wireless operators continue their work but there's no rousing the Californian. (1.10:00) /35 #Titanic108

There are still around 2,000 people on the ship at this point. There are around 900 spots left on the remaining lifeboats. The boat will sink under the waters of the Atlantic in 70 minutes. (1.08:00) /36 #Titanic108

Lifeboat 16 is lowered with 40 passengers. People are beginning to want to leave the ship. This trickle will become a flood very soon. (1.00:00) /37 #Titanic108

Lifeboat 14 is mobbed by male passengers. Officer Lowe is forced to fire warning shots to stop them. The lifeboat is lowered with 58 aboard. The first class dining saloon starts to flood. (0.55:00) /38 #Titanic108

Lifeboats 9 & 12 are both lowered with full complements. Most evacuees are first class women and children. Third class passengers are still mostly in the bowels of the ship. (0.50:00) /39 #Titanic108

The mood has changed to something closer to panic now. The band continues to play to try to maintain calm. The ship is down at a noticeable angle now. (0.49:00) /40 #Titanic108

Lifeboat 11 is lowered with 70 aboard - 5 over capacity. People are now desperate to leave what is very obviously a doomed ship. Noise levels in deck are very high. Lights continue to flicker occasionally. (0.45:00) /41 #Titanic108

The iceberg was struck nearly two hours ago. 1,800 people remain on the ship. The final rocket is launched but no ships have responded. The distant light of the Californian has vanished from the horizon. (0.42:00) /42 #Titanic108

Officer Moody lowers a full lifeboat 13. Last sighting of Thomas Andrews around this time, standing in the first class smoking room staring at a painting, his life jacket on a nearby table. He would go down with the ship. (0.40:00) /43 #Titanic108

Lifeboat 15 is lowered onto lifeboat 13, almost crushing it. Chaos is beginning to ensue. Lifeboat 13 avoids this fate, just. Lifeboat 2, right forward near the rising waters, is lowered with only 25 aboard. Most passengers are now congregating on the stern. (0.35:00) /44

Lifeboats 10 & 14, the last two 'proper' boats, leave with only half the maximum occupancy. Too many passengers are at the stern, as far away from the rising icy waters as possible. The band plays on. Third class still trapped. (0.30:00) /45 #Titanic108

Collapsible boat C is centre of attention now, as its stormed by male passengers and J Bruce Ismay climbs aboard in a move that would ruin his reputation and life. Water is lapping A deck now. (0.20:00) /46 #Titanic108

Captain Smith relieves the two wireless operators, Phillip and Bride, of their duties, tells them to do what they can to escape. They keep working.

Water has reached the bridge. 3 lifeboats left. (0.15:00) /47 #Titanic108

Collapsible D is lowered, with 22 women and children. Two male passengers jump aboard too at last minute and escape. (0.14:00) /48 #Titanic108

Captain Smith tells his crew its every man for himself. Last seen entering the bridge before it submerged. (0.12:00) /49 #Titanic108

Collapsibles A and B float upside down from the roof of the sunken bridge. Male passengers camber aboard. The band plays its last tune - possibly Nearer My God to Thee, though it may gave been Autumn. (0.10:00) /50 #Titanic108

Water reaches the base of the first funnel. Its guy wires snap, and the funnel collapses forward onto swimmers in the water including John Jacob Astor, the richest man aboard. The lifeboats row frantically to gef away from the ship. (0.09:00) /51 #Titanic108

The stern rising rapidly, poop deck full of the remaining 1500 people aboard, the great glass dome above the grand staircase caves in and water swamps the stairwell. Benjamin Guggenheim is lost. The three huge screws at the aft rise from the water. (0.05:00) /52 #Titanic108

The second funnel falls as the ship reaches an angle of 23 degrees. The lights flicker and are extinguished forever. 1500 people plunged into utter darkness. There is no moon. Only starlight. (0.03:00) /53 #Titanic108

With a vast crash the interior fittings of the ship settle forward, smashing through bulkheads and walls. The angle of the stern out of the water gets steeper. (0.02:00) /54 #Titanic108

A roar is heard as the ship tears itself in two thanks to the huge weight of the stern out of the water. Not much of this is seen due to the sudden darkness. The stern plunges back to near level as the bow sinks. (0.01:00) /55 #Titanic108

The bow, still connected at the keel, drags the stern vertical, with over a thousand souls still aboard. It bobs for a moment, then plunges into the water, leaving hundreds of people in the freezing water. (0.00:00) /56 #Titanic108

The bow plunges over two miles to its final iconic resting place. The stern implodes violently and drifts erratically to the sea bed, leaving a barely recognisable wreck. Lifeboats begin to cautiously pool resources but don't rescue anyone for fear of being overwhelmed. /57

Later, a lifeboat will pick through the dead, trying to find survivors, but it will be too late. The survivors will sit in their tiny boats, freezing, for hours until daybreak when the Carpathia arrives to rescue them. /58 #Titanic108

The 700+ survivors will be taken to New York, where news is confused about what has actually happened. Search boats will be sent out to scour the area, finding some bodies. This takes weeks. /59 #Titanic108

But over 1500 people perished in one of the world's most emotionally affecting tragedies. It wasn't just a film. It happened. And if you've been with me all night you'll agree, it happened horribly quickly and terrifyingly. Here's to the memory of those poor souls. #NeverForgot

Thanks for staying up with me tonight. I'm off to bed now. I hope you learned something from my efforts.
