Monday, April 15, 1912
12:00 a.m.
Lifeboats begin to be uncovered and prepared
Evacuation
The crew begins readying the boats while many passengers still do not fully grasp the seriousness of the damage. The evacuation phase starts cautiously and unevenly, not all at once.
12:15 a.m.
Distress calls are sent by wireless
Warnings
Rescue
Wireless operators begin transmitting distress messages. This is the moment the sinking becomes, in practical terms, a rescue story as well as a shipboard emergency.
About 12:25 a.m.
Carpathia receives the distress and turns toward the scene
Rescue
Wireless operator Harold Cottam alerts Captain Arthur Rostron, who orders Carpathia turned around and driven at full speed through the ice region. This response becomes one of the best-documented and most consequential actions of the entire disaster.
12:40 a.m.
Boat 7 is lowered — first lifeboat away
Evacuation
The first boat leaves starboard side under capacity, a sign of how uncertain and improvised the opening stages of the evacuation still are.
12:43 a.m.
Boat 5 is lowered
Evacuation
Another early starboard boat departs before many aboard fully accept that abandonment may truly be necessary.
12:55 a.m.
Boat 6 is lowered
Evacuation
One of the early port-side boats, later associated with several well-known survivor accounts, leaves with many seats still unfilled.
12:55 a.m.
Boat 3 is lowered
Evacuation
Starboard-side launching continues in parallel, though the overall tempo is still measured rather than frantic.
About 1:00 a.m.
Passengers are more forcefully urged to the boat deck
Evacuation
Warnings
Officers and stewards press more urgently for women and children to come up. The ship’s list and bow trim are not yet dramatic, but enough time has passed for disbelief to begin giving way.
1:05 a.m.
Boat 1 is lowered
Evacuation
This emergency cutter becomes notorious because it is sent away with very few people aboard relative to its capacity.
1:10 a.m.
Boat 8 is lowered
Evacuation
More women and children are now boarding, but the pattern remains inconsistent and shaped heavily by deck location, crew direction, and willingness to leave the ship.
1:15 a.m.
Boat 10 is lowered
Evacuation
Port-side loading continues as the evacuation becomes visibly more organized, though still shaped by confusion and uneven access from different class areas.
1:20 a.m.
Boat 9 is lowered
Evacuation
Boat departures are now occurring more frequently, a sign that the last remaining window for orderly launching is closing.
1:25 a.m.
Boat 12 is lowered
Evacuation
Boat 12 later becomes significant in the rescue phase as one of the last boats recovered alongside Carpathia.
Around 1:30 a.m.
Distress rockets are being fired regularly
Evacuation
Warnings
Rockets continue to rise over the ship as wireless traffic carries on. Their later significance is heightened by testimony regarding the nearby Californian.
1:30 a.m.
Boat 11 is lowered
Evacuation
By this stage some boats are leaving much more heavily loaded than the earliest ones, reflecting the growing urgency aboard ship.
1:35 a.m.
Boat 14 is lowered
Evacuation
Fifth Officer Lowe later uses this boat in some of the more active post-sinking rescue attempts among the nearby lifeboats.
1:35 a.m.
Boat 13 is lowered
Evacuation
As the launch tempo rises, the evacuation becomes more compressed and more hazardous, especially near the ship’s discharge openings and lowering stations.
1:40 a.m.
Boat 15 is lowered
Evacuation
Closely following Boat 13, Boat 15 descends in one of the better-known near-accident episodes of the lifeboat launching sequence.
1:40 a.m.
Boat 16 is lowered
Evacuation
The number of available conventional boats is rapidly shrinking. For many still aboard, options are narrowing by the minute.
1:45 a.m.
Final coherent wireless messages are sent as the ship’s condition worsens
Evacuation
Rescue
The electrical situation is deteriorating, but the distress traffic continues nearly to the end. This moment ties the shipboard collapse directly to the rescue now racing toward it.
1:50 a.m.
Boat C is lowered
Evacuation
One of the Engelhardt collapsibles, Boat C marks the transition from regular lifeboat operations to the last available emergency craft.
1:55 a.m.
Boat 2 is lowered
Evacuation
Though an emergency cutter, Boat 2 leaves relatively late in the sequence and later becomes the first boat picked up by Carpathia.
1:55 a.m.
Boat 4 is lowered
Evacuation
Boat 4’s departure comes after delays linked to deck access and loading difficulties. It is among the last of the standard boats to get away successfully.
2:00 a.m.
Boat D is lowered
Evacuation
The final collapsible launched in anything like an orderly manner, Boat D leaves just minutes before the ship’s remaining deck space becomes unmanageable.
About 2:05 a.m.
Collapsibles A and B are worked on as the last chances off the ship
Evacuation
These final collapsibles are not lowered in the same controlled way as earlier boats. As the bow sinks deeper and deck conditions collapse, they become part of the last desperate phase rather than the organized launch sequence.
Curator note
This is one reason some summaries say “last boat lowered” while others distinguish between the last properly launched boat and the last collapsibles that floated off or were swept from the deck.
The ship disappears beneath the surface, leaving boats, swimmers, wreckage, and debris scattered in darkness. The disaster shifts fully from abandonment to survival and rescue.
About 3:30 a.m.
Survivors in the boats sight Carpathia’s lights and rockets
Rescue
After hours in the boats, the first visual confirmation of help appears. This is one of the major emotional turning points in survivor accounts.
4:00 a.m.
Carpathia reaches the disaster area
Rescue
Captain Rostron brings Carpathia into a dangerous field of ice and debris. The ship herself is gone, so the rescue must now proceed boat by boat.
4:10 a.m.
Boat 2 is the first lifeboat picked up by Carpathia
Rescue
The first successful transfer begins the long recovery phase. Survivors are helped aboard by ladder, sling, and crew assistance, then given blankets, medical care, and warm drinks.
4:10–8:15 a.m.
Carpathia gathers survivors and lifeboats one by one
Rescue
The rescue takes hours rather than moments. Boats come alongside in sequence, and the work is cold, methodical, and physically demanding for both rescuers and survivors.
About 8:15 a.m.
The last lifeboat reaches Carpathia
Rescue
One of the final boats recovered is Boat 12. By now, the active gathering phase is nearly complete, though transfers and final handling continue briefly.
About 8:30 a.m.
The rescue phase is complete: survivors and remaining recovered boats are aboard Carpathia
Rescue
The final survivors have been recovered from the lifeboats. What began as a celebrated maiden voyage has, within five days, become one of the most documented maritime disasters in history.
