Q: Just minutes before the ship started its final plunge, Smith was still busy releasing Titanic's crew from their duties; he went to the Marconi operators room and released Junior Marconi Officer Harold Bride and senior wireless operator John ''Jack'' Phillips from their duties. He then carried out a final tour of the deck, telling crew members: ''Now it's every man for himself.'' At 2:10 a.m., Steward Edward Brown saw the captain approach with a megaphone in his hand. He heard him say ''Well boys, do your best for the women and children, and look out for yourselves.'' He saw the Captain walk onto the bridge alone. This was the last reliable sighting of Smith. A few minutes later Trimmer Samuel Hemming found the bridge apparently empty. Five minutes later, the ship disappeared beneath the ocean. Smith perished that night along with around 1,500 others, and his body was never recovered.
Can we conclude that did captain of titanic go down with ship?
