Fifth Officer Harold Lowe was in lifeboat No. 14. He gathered four more lifeboats (Nos. 10, 12, [unknown] and a collapsible) together and redistributed the survivors in the group of lifeboats to ready one lifeboat to return to the wreck and search for additional survivors. This resulted in the rescue of four men one of whom, first-class passenger William Hoyt, died later that night.
Lowe had his crew of men raise the mast (he was the only officer to make use of the mast and sail in each lifeboat) and the available breeze allowed them to sail to the sinking Collapsible A, from which they plucked twenty-one survivors and left the three dead bodies. He then sailed on to the Carpathia.
Lowe's testimony at the US Senate Inquiry includes this about Collapsible A:
'As to the three people that I left on her - of course, I may have been a bit hard hearted, I can not say - but I thought to myself, "I am not here to worry about bodies; I am here for life, to save life, and not to bother about bodies," and I left them.'
