Hvalfjörður in Iceland to refuel and departed on the evening of 21 August. Late on 22 August, the destination of the force was revealed to the troops. Force A met the oiler

Empress of Canada set out for Archangelsk at midnight on the night of escorted by
Nigeria and the destroyers.
Aurora stayed behind to guard the landing parties and assist in the embarkations from the remoter settlements. The Canadian engineers set fire to about of coal dumped at the mines, fuel oil was poured into the sea or burned and mining equipment was removed or sabotaged, during which, Barentsburg was mysteriously burned down. On the evening of 1 September, the
Empress of Canada and its escorts returned from Archangelsk to Green Bay. Normal business was kept up at the wireless station by the Norwegian Military Governor Designate, Lieutenant
Ragnvald Tamber except for bogus reports of fog, to deter air reconnaissance. Three colliers sent from the mainland were hijacked along with a whaler, icebreaker, tug and two fishing boats. On 2 September, about 800 Norwegians boarded
Empress as did 186 French prisoners of war, who had escaped from German captivity and been interned in the USSR until the German invasion. Force A sailed for home at on 3 September, with 800 Norwegian civilians and the
prizes, after a ten days' occupation, having never been in darkness. Anders Halvorssen preferred not to join the Norwegian army-in-exile, hid and remained on the island. The final wireless message was transmitted on the evening of 3 September and the sets at Barentsburg, Longyearbyen, Kap Linné and Grønfjord were destroyed; as Force A made its return journey, a German station was heard calling Spitzbergen. The spurious weather reports had led to the cancellation of

Adventfjorden, about away, which was about long and could serve as a runway. On 25 September, a
Ju 52 landed safely at Sònak but was unable to send a message due to the low power of its radio; a
Ju 88 managed to land on 27 September, finding the party and the Norwegian defector. A plan to establish a temporary base was abandoned after an odd illumination, resembling searchlights, was seen in the sky; the two aircraft hurriedly took off for Norway in case it was the British. The British cruisers diverted towards the Norwegian coast to hunt for German ships and early on 7 September, in stormy weather and poor visibility, found a German convoy off
Porsanger Municipality, near the
North Cape. The cruisers sank the training ship but
Barcelona and
Trautenfels, two troop transports with 1,500 men of the
6th Mountain Division aboard, escaped into the fjord.
Nigeria was thought to have been damaged by hitting a wreck but after the war it was surmised that it had hit a mine. Force A reached the Clyde on the night of ==Aftermath==
