After the collapse of France, the situation on the northern, Atlantic communication routes became unhappy. There is no question of any English action in Norway, while Germany is free to use its bases. They are starting to look increasingly aggressively at Iceland.

Our base in Reikiavik only manages two battalions of the National Guard, and that - as if something had happened - might not be enough. In addition, the runway at Reykjavik was destroyed by a volcanic eruption. Over the last two weeks, on the Norwegian coast, we are witnessing a large movement of German fleets and transport units. Presumably, the Germans are diverting the units there, who are preparing to attack England. It does not bode well ...

You have two options: first, landing in the port of Kverna and marching land in the direction of Reykjavik, and the other - it sails the bay and landings at Reykjavik on the sea side. The latter seems faster, but we do not know what Kriegsmarine's naval forces have turned to that area.
