The question of what time did the Titanic start sinking points to a specific moment late on Sunday, April 14th, 1912. While the ship struck the iceberg at 11:40 p.m., the catastrophic flooding that doomed the vessel began almost immediately, yet the full sinking was a process unfolding over the subsequent two hours and forty minutes.
The Fateful Collision
On the calm, moonless night of April 14, 1912, the RMS Titanic was cruising at near-top speed despite numerous ice warnings. At 11:40 p.m., lookouts Frederick Fleet and Reginald Lee spotted the massive iceberg directly ahead, and the infamous warning "Iceberg, right ahead!" was relayed to the bridge. First Officer William Murdoch ordered a hard-starboard turn and the engines to full reverse, but the ship's momentum and immense size meant the turn came too late. The Titanic brushed the iceberg along its starboard side, a glancing blow that nonetheless caused a series of fatal gashes in the hull's underwater compartments.
Immediate Onset of Ingress
Although passengers above decks felt only a slight shudder, the damage was severe below the waterline. The collision had ruptured at least five of the Titanic's sixteen watertight compartments, allowing water to pour in at a devastating rate. The ship's designer, Thomas Andrews, quickly assessed the situation and informed Captain Edward Smith that the vessel was doomed, as the first five compartments—the maximum the ship could safely contain—were filling. Consequently, the process of sinking had effectively begun the moment the iceberg scraped the hull, even before any visible sign of distress appeared on the surface.
Timeline of a Disaster
The timeline of the sinking provides a clear sequence of events following the initial impact. Understanding this sequence is crucial for answering the question of when the ship actually began to go down.

The Rate of Sinking
While the initial breach occurred at 11:40 p.m., the Titanic did not sink straight to the ocean floor in a sudden plunge. The ship remained afloat for just over two hours after the collision, allowing for the dramatic evacuation efforts that saved approximately 705 people. The rate of flooding accelerated as the angle increased, with the stern lifting high enough to break free from the water's surface tension before gravity took over completely. This prolonged struggle, visible to the few remaining lifeboats, is a haunting testament to the ship's massive scale and the tragic inefficiency of the evacuation.
