After arriving at the scene, the Carpathia drifts toward Lifeboat 2 with 4th Officer Boxhall in command. The passengers of this boat are brought aboard.
Boxhall informs Captain Rostron that Titanic went down early that morning and that hundreds, maybe even a thousand, went down with her. All of Titanic's remaining passengers and crew make their way toward the Carpathia.

By 8:30am all of the survivors have been brought aboard. Thirteen of Titanic's lifeboats are recovered and stored on Carpathia's deck.
