@ABWorsham:
Churchill proposed an invasion of Northern Norway and Sweden in 1939 to remove half of Germany iron ore. As a new leader he did not have credibility to get this invasion quickly planned before the Germans reacted.
How does the war progress if the Allied Expeditionary Force invades Norway and Sweden?
I was reading this over again. I don’t think it would be possible with an Allied invasion during 1939. Since the mountains are pretty much impassable during winter, which is from October to April, the invasion would have to be done from the start of the war in September and finished before October. This was not likely to happen. The first window of opportunity opened in November when Russia attacked Finland. But in the case of Finland, snow and ice was a necessity for a successful campaign, since that part of Finland is impassable swamps and marshes during summer. In Norway it is the other way around, since mountains are impassable during winter. And that give Britain a first possible D-day on April 8th 1940, the day before Germany did actually attack Norway.
The reason Britain did not attack on April 8th is IMHO that they got reports of a German breakout into the sea, so they ditched the infantry already onboard, and sailed to intercept the German fleet. But as w know, the Germans had then walked down the gangway in all major Norwegian ports. And they could do so because the ports were not defended. But here comes the twist. Next day Britain sailed in 25 000 troops bound for the Narvik area, but they was not able to kick out the 1900 Germans, because at that time Britain lacked landing ships and landing crafts. And you can not amphibious assault a defended coast without landing crafts, as proven in the Normandy landings 1944.
So basically the 25 000 Allied troops sat in the port of Harstad waiting for landing crafts to be build and this took 7 weeks, before they ware able to invade Narvik late in June , by then defended by 40 Germans. In the meantime 10 000 Norwegians equipped with winter gear and trained in mountain warfare, were pushing the bulk of the Germans towards the Swedish border.
I figure, if the Brits had landed in Narvik April 8th 1940 and walked down the gangway as friends, the Germans would for sure be cut of from the iron ore. But if the Norwegian socialist government had declared war, then I cant see how the Brits could have been able to break out from Narvik and cross the mountain range over to Sweden. None of the total 35 000 Brits, French and Polish soldiers in Norway 1940 had winter equipment nor training in mountain warfare. The last blizzard was in may, and they would be stuck in Narvik until then, surrounded by a Norwegian mountain division. And on the other side of the border, 320 000 Swedish soldiers, also trained in winter and mountain warfare, would wait for them, protecting the iron mines. So Churchills plan could only work if Norway and Sweden did cooperate volunterely
