Reason to invade not to invade northern Norway.
If 1942 is a slack year for the British despite any Japanese actions, which will in the end mostly be covered by forces from India, as they were IOTL. Winston will be chomping at the bit to do something, anything to assist the Soviets, and take the war to the Germans. Yes he will want to strike at the so called soft underbelly in Greece and Italy, and for the Germans to be bombed back in to the Stone Age, while supporting an ever increasing resistance movement in Europe, to set it ablaze. Winston was a man with very little patience, and hated the attitude of when the time is right we will do something, just not now. He wanted to do it not now but last week, and was highly frustrated by those who took a measured approach to the problems before them. So Norway, are there any good reasons to invade northern Norway, and do they outweigh those reasons not to.
So reasons for the British to invade northern Norway in 1942, despite the problems and in the face of all the advice from the Chiefs of Staff. Once the Germans invade the Soviet Union, and Britain starts the run supply convoys to Murmansk and Archangel, in 1941, it became obvious that the majority of the opposition forces were based in northern Norway. If Britain was to invade and capture northern Norway from Bodo, on up past Narvik, incorporating all the land up to the Soviet border. You have eliminated the majority of the submarine bases, and airfields from which the attacks on your convoys start. You now have airfields to base anti submarine patrol aircraft from, fighters to defend against Germany air attacks. And you can use Narvik as a base for both anti submarine patrols to prevent them from coming north, and as a midway point for some of the close escort. In addition I am assuming that as Narvik is the port at the end of the rail line from Sweden, through which Swedish iron ore is exported during the winter when the Baltic freezes over, it can be kept open all year round. So during the winter months buy all the iron ore you can from Sweden, the Germans can not complain, as with the Baltic frozen over, they can not buy it and ship it themselves. At the same time increase your purchases of Swedish ball bearings, which you can now ship out without the risk of running blockade runners past Denmark. And use the railway to ship in oil and grain to Sweden, plus letters and parcels for you POW’S in Germany. The convoys to the Soviet Union which had to be suspended during the summer months as the near perpetual daylight made them too costly to run, will be possible all year round. And while you are not going to be able to push south and liberate southern Norway easily, the same applies to the Germans, who are not going to be able to push you out of the north, without making a major commitment.
Is it such a good idea to invade northern Norway, and what are the potential consequences of such an invasion. Without doubt such an invasion is going to be difficult, while the landings will not be too hard, the Germans just don’t have a big enough garrison to prevent you from landing. You are going to have to deploy vertically all of your aircraft carriers, until you can develop airfields on land to provide air coverage. You are committing yourself to a long campaign in some of the most inhospitable land in Europe, and it lacks resources, so everything will have to be brought in. It is doubtful that you will be able to replace the British ground and airforces needed to secure a defend this area with Norwegian forces, there are not enough Free Norwegians in Britain. And while you will be able to attract a lot of young Norwegian men and women, to make their own way north, ether directly or via Sweden. I do not think that you will get enough to take over the defence, or have the ability to train those who do answer the call, in Norway. The Germans are going to put the Swedish under increasing pressure, to not sell their iron ore, ball bearings, and anything else they have that the British want, to the British. They will demand that any Norwegians that cross into Sweden and detained and placed in detention facilities, to prevent them from travelling north to join their Free Norwegian countrymen. The maintenance of the forces are going to be a continuous cost and drain on British resources, which might be better spent elsewhere. And the commitment once made, can not be abandoned without significant loss of face, and political consequences. So you are left with the question, do the benefits out weight the costs, and by what standard do you make the decision. Me I will remain neutral, I can see both sides of the argument, yes it is given the present conditions a good idea, but whether the cost is low enough and the benefits high enough, needs to my mind more thinking time.
Side note, in the Mediterranean an invasion of Rhodes and other Greek islands is a given, once the conflict in North Africa has ended. The cost to the Germans/Italians of trying to defend them with the British on Crete, is high, and the cost to the British of once Rhodes has been taken, of biting off the others one by one low.
