The ship was commissioned by the USA-based Commercial Cable Company from then noted River Clyde-based warship builders John Elder & Co. at their Fairfield Yards. The company incorporated a number of then new and original features into the cable ship. It was one of the first ships built from steel rather than iron, and she had a relatively deep keel design to both accommodate as much cable as possible and to keep the ship stable in the Atlantic Ocean swells. The design was also very hydrodynamic to keep her fuel efficient and fast in operation. The hull design included bilge keels to keep her stable, and she had two rudders, one fore and one aft, to maximize manoeuvrability.[1]
Named for two founders of the Commercial Cable Company, John W. MacKay and James G. Bennett, she was launched late in 1884.[2] Mainly based in Halifax, Nova Scotia, where she first arrived in March 1885,[3] she was also often used for operations on the European side of the Atlantic, based out of Plymouth, England. The Canadian author Thomas Raddall worked as wireless operator aboard Mackay-Bennett and based some short stories on his experiences aboard.
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.[4]
In April 1912, she was berthed at Halifax during a period of long-term work maintaining the France-to-Canada communications cable. Of the three ships in Halifax at that time only Mackay-Bennett had a hold capable of holding the 125 coffins and ice forming part of the exercise to recover bodies. The ship became notable as the main 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. The task was further motivated by Joseph Astor's announcement of a $100,000 reward for the ship recovering the body of his father J. J. Astor.[5] Her captain, Frederick H. Larnder, took on board a combination of specialists and an effective mobile mortuary.[1] [6] Both additional and specialized personnel and supplies were taken on board for the assignment. These included:
Crew were paid double pay for the grisly task. There was a hierarchy to the mortuary details as the ship could never hope to bring all back: first class passengers were embalmed and placed in coffins; second-class were wrapped in linen winding sheets; third class and crew bodies were weighted and buried at sea (116 in total).[7]
The ship left Halifax at 12:45 P.M. on Wednesday, 17 April 1912. Due to severe fog and rough seas it took the ship nearly four days to sail the to the scene of the disaster. The captain instructed the ship's crew to keep their logbooks complete and up to date during the voyage and subsequent recovery operation, but only two logbooks are presently known to have survived: seven pages from the logbook of engineer Frederick A. Hamilton, now kept in the National Maritime Museum, England, and the personal diary of Clifford Crease, a 24-year-old Naval artificer (craftsman-in-training); much of the detailed account of the recovery operation is today traced to Crease's diary, now held in the Public Archives of Nova Scotia.[1] [8]
The ship arrived at the scene during the night, so recovery of bodies began at 06:00 on 20 April.[1] CS Mackay-Bennett was anchored close to but not within the recovery area, and she offloaded her skiff lifeboats. Crews then rowed into the recovery area and manually recovered the bodies into the skiffs. After recovering as many bodies as they deemed safe for the return journey (51 corpses), the crews then rowed back to the CS Mackay-Bennett.[1] The captain noted that there was neither sufficient space aboard to store all of the recovered bodies nor enough embalming supplies aboard. As the Canadian Government and associated burial and maritime laws directed that any bodies carried had to be embalmed before a ship enter a Canadian port, the captain agreed to a system whereby:[1] [9]
At 19:00 on 23 April, CS Mackay-Bennett lay briefly alongside the Allan Shipping Line's Sardinian (en route to Saint John, New Brunswick), to collect additional canvas.
Just after midnight on 26 April, CS Mackay-Bennett rendezvoused with the Anglo-American Telegraph Company's CS Minia to get extra embalming supplies, before departing for Halifax at dawn that day.
After a seven-day recovery operation, the CS Mackay-Bennett had:
The crew split the $100,000 reward for Astor's body (around $2500 each). Using some of that money they paid for the burial of the body of the unknown child and his headstone monument - the casket was marked by a copper plaque reading "Our Babe".[1] The entire ship's crew, together with the majority of the population of Halifax, attended the child's burial at Fairview Lawn Cemetery on 4 May 1912.[1] [13] With improved DNA testing, on 30 July 2007 Canadian researchers at Lakehead University announced that testing of the body's mitochondrial DNA had revealed that the child was 19-month-old Sidney Leslie Goodwin.[14]
After his death in 1961, Clifford Crease's body was interred only a few steps away from the grave of "Our Babe", a site he had visited on every anniversary of the tragedy during his lifetime.[8]
Mackay-Bennett Seamount, one of the Fogo Seamounts southeast of the Grand Banks of Newfoundland in the North Atlantic Ocean, is named after Mackay-Bennett for her involvement in the Titanic disaster.[15]
The ship was retired in May 1922, anchored in Plymouth Sound to be used as a storage hulk. During The Blitz on England in World War II, she was sunk during a Nazi Germany Luftwaffe attack but later refloated. Her hull was finally scrapped in 1965.[16]
