 In addition to carrying out numerous difficult cable repairs, many during times of wartime danger, due to the nature of her work and resultant position in the Atlantic, "Mackay-Bennett" performed many rescues.Typical was the rescue of the crew of the sinking schooner "Caledonia" on 12 February 1912.In April 1912, whilst working on maintaining the France-to-Canada communications cable, the ship became famous as the first vessel contracted by the White Star Line to carry out the difficult task of recovering the bodies left floating in the North Atlantic, after the disaster.
