Location where Crown Arun was torpedoed and sunk.

Crown Arun was a 2,372 GRT cargo ship which was built by Actien-Gesellschaft „Neptun“ Schiffswerft und Maschinenfabrik, Rostock as Hannah Böge. She was captured at sea on 3 September 1939 and declared a war prize. Taken into service by the British Government, Crown Arun was torpedoed and sunk by U-99 on 17 September 1940.


Hannah Böge was built for Reederei Johann M. K. Blumenthal, Hamburg.[1] She was yard number 477, and was completed in March 1938.[2] Her port of registry was Hamburg.[3]

On 26 August 1939, Hannah Böge departed Shediac, New Brunswick, bound for Germany.[4] On 1 September 1939, Germany invaded Poland, starting the western portion of the Second World War. As a result, on 3 September, the United Kingdom declared war on Germany. Later that same day, Hannah Böge was intercepted by HMS Somali, becoming the first British war prize taken at sea.[5] Her location was 63°20′N 16°35′W / 63.333°N 16.583°W / 63.333; -16.583.[4] She was carrying a cargo of wood pulp. At the time of her capture, the crew were trying to disguise Hannah Böge although she was still flying the German flag. She was escorted to Kirkwall, Orkney Islands, where she arrived on 5 September.[1]

After she was declared a prize of war, Hannah Böge was renamed Crown Arun and taken into service. Ownership was assigned to the Ministry of Shipping and she was placed under the management of Christian Salvesen Ltd, of Leith. Her port of registry was changed to London.[6] Crown Arun was a member of a number of convoys.

ON 14

Convoy ON 14 departed the Methil Roads on 17 February 1940 bound for Norway. It diverted to Kirkwall on 18 February owing to a lack of cover. This was to be supplied by HMS Hood, HMS Rodney and HMS Warspite. The convoy departed Kirkwall on 20 February and arrived in Norway on 22 February.[7]

OB 151

Convoy OB 151 departed Liverpool on 21 May and dispersed at sea on 22 May. Crown Arun was carrying a cargo of coal from Glasgow to Montreal.[8]

SHX 71 / HX 71

Convoy HX 71 departed Halifax, Nova Scotia, on 5 September and arrived at Liverpool on 20 September. Convoy SHX 71 departed Sydney, Nova Scotia, on 6 September and was to join HX 71 at sea. Crown Arun was part of this convoy. SHX 71 joined with HX 71 by midday on 8 September, although Crown Arun was straggling behind by this time.[9] Crown Arun was carrying a cargo of 2,800 tons of pit props from Gaspé, Quebec, destined for Hull. At 08:32 German time (07:32 British Time) on 17 September, Crown Arun was torpedoed north of Rockall (58°02′N 14°18′W / 58.033°N 14.300°W / 58.033; -14.300Coordinates: 58°02′N 14°18′W / 58.033°N 14.300°W / 58.033; -14.300) by U-99 under the command of Otto Kretschmer. She was finished off by gunfire. The 25 crew were rescued by HMS Winchelsea and landed at Liverpool.[10]
