DEMS SS Beaverford

The SS Beaverford was a Canadian Pacific Steamship Company cargo liner. Beaverford was the first of five cargo ships built by Canadian Pacific in 1927 and 1928 including sister ships Beaverdale, Beaverburn, Beaverhill and Beaverbrae. Designed to carry 10,000 deadweight tons of cargo as well as 12 passengers, they were fitted with 80,000 cubic feet of insulated cargo space and 20,000 cubic feet of refrigerated cargo spaces for meat and fruit. Their twin screws were powered by six Parson steam turbines and were among the most efficient steam engines of their time. Their boilers were fitted with Erith-Roe mechanical stokers, the first automatic stokers in the British merchant service.
With the onset of war, the fast and modern beaver ships were requisitioned by the British Admiralty to carry high-value stores. Beaverford was fitted with two guns for self-defence, a four-inch gun on the stern and a three-inch gun on the bow. She remained owned by Canadian Pacific with a Merchant Navy crew, along with two with two DEMS gunners. Beaverford sailed from Halifax, Nova Scotia on 28 Oct 1940 as part of Convoy HX-84.
Convoy HX-84 was half way across the Atlantic when it was located and attacked by the German heavy cruiser Admiral Scheer on 5 Nov. The attack began at 17:15. The convoy’s only escort, the Armed Merchant Cruiser HMS Jervis Bay ordered the convoy to scatter. In an engagement that won the commander of HMS Jervis Bay a posthumous Victoria Cross, the escort steered directly towards Admiral Scheer. Hopelessly outgunned, HMS Jervis Bay was set afire and sank 22 minutes later. The Admiral Scheer now began to attack the convoy, first sinking the SS Maidan with all hands. The tanker San Demetrio was set on fire, but did not sink. The Admiral Scheer next sank the freighters Trewllard and Kenbane Head.
Captain Pettigrew aboard Beaverford had begun to scatter but as he watched the Admiral Scheer close on Kenbane Head, he ordered Beaverford to turn and engage the German heavy cruiser. Beaverford opened fire with her 3-inch bow gun. The first shot landed unexpectedly close to the German heavy cruiser. The Admiral Scheer turned all its attention to this unexpected challenge firing star shells to illuminate Beaverford as darkness had now fallen. Beaverford turned to bring both of its two small guns to bear and fire at the German cruiser although neither gun was in range. Beaverford sent out a wireless message as it engaged the German cruiser, “It is our turn now. So long. The captain and crew of SS Beaverford”.
The Admiral Scheer opened fire on Beaverford with its 11-inch guns. However Beaverford used the reserve power of its turbine engines to quickly turn and evade the fire as the shots landed in the water, missing Beaverford although the shrapnel started small fires on amidst her deck cargo. The ships of the dispersing convoy had laid a thick smoke screen from floating smoke floats and Beaverford was able to disappear into the smoke screen. The Admiral Scheer, its radar broken from the prolonged bombardment of HMS Jervis Bay had difficulty in locating the new challenger in the smoke and darkness. Beaverford, one of the faster ships in the convoy, had a chance to escape in the darkness, but for reasons unknown, Captain Pettigrew stayed to fight it out with the Admiral Scheer. For the next four hours, Beaverford played a cat-and-mouse game, emerging from the smokescreen to fire at the Admiral Scheer and then seeking cover into the smoke. Captain Theodor Krancke in command of the Admiral Scheer had identified Beaverford as “Target No. 9” and thought he had destroyed the freighter, only to find the ship reappearing to confront him again.
However, every time Beaverford emerged from cover, the ship was hit by the Admiral Scheer's firepower. In all, the Admiral Scheer fired 83 shells at Beaverford, 71 from its 5.9-inch guns with 16 hitting the unarmoured freighter, and 12 from the cruisers massive 11-inch guns with three making hits. Beaverford began to take on water and slow. Fires spread on the freighter making it easier for the enemy guns to find their mark. Finally at 22:45, the Admiral Scheer was able to destroy Beaverford with a torpedo. The torpedo hit the fore part of Beaverford, lifting the bow and detonating the ammunition in her hold. The ship blew apart and the stern was last seen sliding into the ocean. All aboard were killed in the sinking. Beaverford had taken up the fight with the Admiral Scheer for almost five hours. Delayed by Beaverford, the German cruiser was only able to find and sink one more ship from the convoy, SS Fresno City. Of the 38 ships in the convoy, the Admiral Scheer had only succeeded in sinking six. (Wikipedia)
DEMS SS Jasper Park

SS Jasper Park (Canadian Government) was torpedoed by U-177, Indian Ocean, west of South Africa on 6 Jul 1943. She was the first Park Ship lost to enemy action in the Second World War.
U-177 Action Report: At 10.05 hours on 6 July 1943 the unescorted SS Jasper Park (Master William Buchanan) was hit by two of three torpedoes from U-177 south-southwest of Cap Sainte Marie, Madagascar. The ship had been attacked with a spread of two torpedoes at 21.25 hours the day before, but one malfunctioned and the other probably detonated in the deployed torpedo nets without damaging the ship. At 11.04 hours, a coup de grâce was fired which either missed or was a dud, so the U-boat surfaced to sink the vessel by gunfire but just then she sank. The Germans then questioned the survivors in two lifeboats before leaving the area. Of her crew of 55, four were lost. The master, 44 crew members and six gunners were picked up by HMAS Quiberon (G 81) (Cdr G.S. Stewart, RAN) and HMAS Quickmatch (G 92) (LtCdr R. Rhoades, DSC, RAN) and landed at Durban.
