Harold Cottam was a 21-year old radio operator who was on duty on the night of April 14th, 1912 on board passenger ship RMS Carpathia when he received a Morse code message he would never forget.

Nor would the world, for Cottam was the telegraphist who picked up the first distress call from the RMS Titanic.

The RMS Carpathia was about four hours away from the Titanic, and steaming in the opposite direction towards the Mediterranean.

Its captain Arthur Rostron, changed course – which meant heading for ice - and took a number of measures to increase speed while ordering the crew to prepare food, blankets and medical care for any survivors.

The lesser-known story of the Carpathia’s role in rescuing 705 Titanic survivors has been recalled by Belfast author and illustrator Flora Delargy, whose grandfather and great grandfather both worked in the Belfast Shipyards where the Titanic was built.

Morse code, navigation tools, the different roles of the crew, how the ships found each other, and by-the-minute details of exactly what happened on this cold and fateful night are reflected in her illustrated text, which has received critical claim from British publication The Bookseller.

Incidentally, the Carpathia, a Cunard Line passenger steamship, was sunk six years later on July 17th 1918 off the south Irish coast after being torpedoed three times by German submarine U-55.
