Crown Arun was a 2,372 GRT cargo ship which was built by Actien-Gesellschaft „Neptun“ Schiffswerft und Maschinenfabrik, Rostock as Hannah Böge.
Later that same day, Hannah Böge was intercepted by HMS Somali, becoming the first British war prize taken at sea.
At the time of her capture, the crew were trying to disguise Hannah Böge although she was still flying the German flag.
[1] After she was declared a prize of war, Hannah Böge was renamed Crown Arun and taken into service.
Convoy SHX 71 departed Sydney, Nova Scotia, on 6 September and was to join HX 71 at sea.
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.
[10] Tragically, the departure of the Winchelsea from Convoy OB 213 to protect HX 71, resulted in the torpedoing of the SS City of Benares, which sank in 31 minutes, with the loss of 258 people of 406 on board, including 81 out of 100 children, 35 of 55 women, and 142 of 251 men.
