SS Polar Chief
SS Polar Chief was a merchant steamship that was built in England in 1897 and scrapped in Scotland in 1952. In its 55-year career it had previously been called Montcalm, RFA Crenella, Crenella, Rey Alfonso, Anglo-Norse and Empire Chief. Early in the First World War it spent eight months pretending to be the battleship . The ship was built in Newcastle upon Tyne as the cargo liner Montcalm. In the First World War it was a troop ship, a dummy battleship and a depot ship, and then in 1916 was converted into the oil tanker Crenella. It spent about 20 months in the Royal Fleet Auxiliary, survived being hit by a torpedo in 1917, and returned to civilian service in 1919. In 1923 she was sold to Norwegian buyers who renamed her Rey Alfonso and had it converted to carry whale oil. In 1927 she was sold back to UK owners who renamed it Anglo-Norse and had her equipped as a whaling factory ship. In 1929 new owners bought her and renamed her Polar Chief. She was laid up in Norway in September 1939, but returned to Britain that December. In the Second World War the ship carried heavy fuel oil and other cargoes as well as whale products. In 1941 the Ministry of War Transport acquired it and renamed it Empire Chief. In 1942 it ran aground, but was refloated and repaired. In 1946 she was returned to commercial ownership and it name was returned to Polar Chief. In 1952 she was scrapped by two shipbreakers in the west of Scotland. Building
Montcalm was the first of a set of four sister ships built for the African Steamship Company. Palmers Shipbuilding and Iron Company in Jarrow built her, launching her on 17 May 1897 and completing her that August. Sir Raylton Dixon and Company in Middlesbrough built her sister ship , launching her on 17 June 1897 and completing her that September. The dimensions of the two ships were almost identical. Montcalms registered length was , her beam was  and her depth was . As built, her tonnages were  and . of her cargo space was refrigerated. She was primarily a cargo ship, but she had berths for 12 Second Class passengers. Three double ended boilers supplied steam at  to her three-cylinder triple expansion engine, which drove her single screw. Her engine was rated at 664 NHP and gave her a speed of . In 1897 Elder, Dempster registered Montcalm in Liverpool. Her UK official number was 106869 and her code letters were PTDS. Elder, Dempster & Co ordered a second pair of ships from Palmers, built to the same design. Monteagle was launched on 13 December 1898 and completed in March 1899. Montfort was launched on 13 February 1899 and completed that April. Career

Montcalm in peacetime
At the start of her career, Montcalm was managed by the African Steamship Company's parent company Elder, Dempster & Co. On 3 September 1897 she started her maiden voyage from Avonmouth to Montreal. On 13 November 1898 she was chartered to the Atlantic Transport Line. Between then and January 1900 Montcalm made eleven trans-Atlantic voyages between New York and either London or Gravesend. On 5 April 1900 she sailed from Liverpool for Cape Town as a transport ship for the Second Boer War. Montcalm then made six return voyages between Cape Town and New Orleans, carrying horses or mules. In September 1900 The Daily Telegraph reported that she sustained a mutiny. Her English stokers had refused to work with several Danes who had been signed on to the ship, and US muleteers caring for her cargo of 1,400 mules objected to the quality of food aboard. In 1900 Montcalms tonnages were increased to  and . However, in 1901 this was reversed and she was assessed at  and . In June 1902 Montcalm started the first of four round trips between Avonmouth and Montreal. On 10 December that year she left Avonmouth for Saint John, New Brunswick. In 1903 she passed to Elder Dempster Lines when that company absorbed the African Steamship Company. On 6 April 1903 the Canadian Pacific Railway bought Elder, Dempster's shipping service to and from Canada, with 14 ships including Montcalm and her three sisters. On 21 May 1903 she sailed from Swansea. Her usual route with Canadian Pacific was between Avonmouth and Montreal or Saint John, New Brunswick. She occasionally visited Bristol, Liverpool or Quebec, and on 11 March 1913 she called at Greenock. By 1911 Montcalm was equipped for wireless telegraphy and submarine signalling. The Marconi Company supplied and operated her wireless equipment under contract. By 1913 her wireless call sign was MLZ. Montcalm in the First World War
In August 1914 the Admiralty requisitioned Montcalm. She was initially used as a troop ship carrying members of the British Expeditionary Force. In October 1914 she was converted to a dummy battleship, mimicking , whose name she carried. She was a member of a dummy battleship squadron, which was disbanded on 6 July 1915.

In September 1939 Polar Chief was laid up at Tønsberg, but that December she left Norway in Convoy HN 5 to the Clyde. In the early part of the Second World War she continued whaling, visiting South Georgia in March 1940. In an attempt to reduce exposure to U-boats and German surface raiders, she sailed via the Western Atlantic. On her outward voyage she called at Curaçao. On her return voyage she called at Aruba, and then Halifax, Nova Scotia, where she joined Convoy HX 35 to reach The Downs off the coast of Kent. Her cargo on her return voyage was furnace fuel oil. On 2 July 1941 the Ministry of War Transport acquired Polar Chief and appointed Christian Salvesen & Co Ltd to manage her. She sailed independently to New York, and returned via Halifax where she joined Convoy HX 141 to Belfast Lough. In October 1941 she sailed to New York again, returning via Halifax to join Convoy HX 156. Empire Chief
On 17 November 1941 Polar Chief was renamed Empire Chief. On 16 January 1942 she ran aground at Reykjavík, Iceland. She was refloated on 7 March and temporarily repaired.
