Global History & Background

On 09 June the French submarine RUBIS, a Saphire class sub, launched mines in Hjeltefjorden that caused the ship Sverre Sigurdssøn to sink 1815 on 10 June 1940. Rubis was launched 30 September 1931 in Toulon, France and went into active service in April 1933. She was assigned to Brest in January 1940, to operate in the fart north and help Finland, but she did not arrive before Finland surrendered by the Treaty of Moscow of 12 March 1940. England requested at the same time reinforcement in minelaying submarines and she was set in service out of Dundee on 1st may 1940.

At this moment, France recalls the submarines, the English get the minelayer to participate in a final operation. On June 20, she left for Trondheim, The Armistice of 22 June 1940 was signed at 18:36 near Compiègne, France, by officials of Nazi Germany and the Third French Republic, “communication difficulties” kept the crew in the dark about this event, and the Rubis laid its mines on June 26.

During the Norwegian campaign, in May 1940, Rubis laid mines off the Norwegian coast; the boat’s mines claimed four Norwegian vessels in May and June, and a further three merchant ships in July. At the time of the French surrender on 22 June 1940, the boat was in the port of Dundee, Scotland in the United Kingdom, where the boat promptly joined the pavilion of the Free French Forces. After the the British admiralty launched “Operation Catapult” by surprise  on 03 July 1940. At that time, she was commanded by Capitaine de Corvette Georges Cabanier. The crew’s desire to continue the fight (only an officer, a non-commissioned officer and 3 sailors returned to France) were such that the Rubis became one of the first submarines of Free France. Their enthusiasm for the struggle against Germany inspired them to acts of great daring. By war’s end the tiny Rubis would be the most successful unit of the entire Free French navy.

When passing Måløy the pilot gives directions trough the usual route. At Hindesøy they did a safetydrill with boats and wests, everything was working as it should.
