The City of Boston sailed from Halifax, Nova Scotia for Liverpool on 28 January 1870 commanded by Captain Halcrow. She had 191 people on board: 55 cabin passengers, 52 steerage passengers and a crew of 84. A number of the passengers were prominent businessmen and military officers from Halifax. She never reached her destination and no trace of her was ever found. A violent gale and snowstorm took place two days after her departure which may have contributed to her loss. Collision with an iceberg was another explanation suggested at the time. City of Boston had been fitted with a two-blade propeller to replace her original three-blade propeller which had been broken during her previous voyage, and Captain Brooks of the SS City of Brooklyn expressed the opinion that the new propeller would not be strong enough to let her make headway against the adverse weather.
Rumors of the "Dynamite Fiend"
On 11 December 1875 the mystery of the City of Boston took a brief turn, that looked like it might give a solution, albeit a melodramatic one. On that day the German seaport of Bremerhaven was the scene of a dynamite explosion that killed eighty people. It turned out that a barrel being stored on board a ship had been a specially made dynamite bomb with a remarkable timer. It was to explode and sink the ship and kill most out at sea. The purpose was to collect insurance on the cargo. The premature explosion of the barrel caused the man responsible to shoot himself. He became known in the period as the "Dynamite Fiend". In time Thompson was revealed to be one Alexander Keith, Jr. a Canadian from Halifax, Nova Scotia. In the wake of the discovery of his scheme and crime, police departmentsaround the world were wondering if Thompson/Keith had been involved in the disappearance of other ships. Thompson had been in New York City in the winter of 1870, and it was wondered if he had any hand in the disappearance of the City of Boston. At the time he had sent two large money transfers to his wife from New York, and that looked like a possible pay-off by some partners in the scheme. As he came from Halifax, and the City of Boston was headed for Halifax, it looked like there could be a connection, especially as part of the cargo included a shipment of furs by one "James Thompson" of Halifax. However, further investigation found that Mr. James Thompson was a real merchant, who lost a valuable shipment of furs on the City of Boston, and was unable to get the shipment insured. After that the possibility of a link between Thompson/Keith and the disappearance of the City of Boston diminished.
