A ceremony will mark the centenary of the biggest rescue in the Royal National Lifeboat Institution's history when a liner crashed off Cornwall.
It took volunteers 16 hours to rescue all of the people on board
The 12,000 tonne liner SS Suevic was on her way to Southampton when she hit Maenheere Reef, near the Lizard, in dense fog and a strong gale.
RNLI lifeboat volunteers rescued 456 passengers, including 70 babies.
The Lizard lifeboat station is being presented with a special certificate to mark the rescue on 17 March 1907.
The rescue was the biggest in the 183-year history of the RNLI.
Volunteer crews from the Lizard, Cadgwith, Coverack and Porthleven rowed out repeatedly for 16 hours to rescue all of the people on board.
Six silver RNLI medals were later awarded, two to SS Suevic crew members.
An RNLI spokesman said: "There has never been a rescue of this magnitude."
Six RNLI medals were awarded after the rescue
The commemoration certificate, signed by the RNLI chief executive Andrew Freemantle and chairman Admiral Sir Jock Slater, is to hang in the boathouse.
It will be presented to the Lizard station by Bob Drew and John Moore, descendents of the Cadgwith coxswain Edwin Rutter.
Historian Peter Greenslade, RNLI Honorary Secretary at the Lizard lifeboat station, said they would have been in open boats "at the mercy of the sea".
"It must have been terrifying and yet they went back to the Suevic time and time again.
"I, and the present day RNLI volunteers at the Lizard have nothing but admiration for what they all achieved."
