Water has poured in and risen 14 feet in the front part of the ship.

Captain Smith is told that the ship can only stay afloat for a couple of hours. He orders radio operators Harold Bride and Jack Phillips to send "CQD", the distress call.

12:05am:

Orders are given to uncover the lifeboats and to get the passengers and crew ready on deck. But there is only enough room in the lifeboats for about half of the estimated 2,228 people on board.

12:25am:

The order is given to start loading the lifeboats with women and children first. The Carpathia, southeast of the Titanic by about 58 miles, picks up the distress call and immediately heads, full speed, to the rescue.

12:45am:

The first of the lifeboats is safely lowered away. It can carry 65 people but pulls away from the Titanic carrying only 28!

The first distress rocket is fired. Eight rockets will be fired throughout the night.

Water begins to reach the Titanic's name on the bow. The tilt of the deck grows increasingly steeper. Lifeboats now begin to leave more fully loaded.

Most of the forward lifeboats have been lowered. Passengers now move towards the stern of the ship.

2:05am:

The last lifeboat leaves. There are now over 1,500 people left on board the sinking ship. The tilt of the Titanic's decks grows steeper by the minute.

2:17am:

The last radio call for help is sent out. Captain Smith tells his crew "It's every man for himself!"The Titanic's bow plunges under. Many passengers jump over board. The forward funnel collapses, crushing a number of people.

Items in the ship are heard crashing through walls and falling toward the sinking bow. The ship's lights blink once and then go out. Several survivors see the ship break in two. The bow section sinks.

2:20am:

The Titanic's broken off stern section settles back into the water, becoming level for a few moments. Slowly it fills with water and again it tilts its end high into the air, before sinking into the sea. Those struggling in the icy water slowly freeze to death.

The rescue ship, Carpathia's rockets are sighted by the survivors in the lifeboats.
