Anyway to those who might be interested continuing this, some background and an update on what is going on after the German defeats in the West:
The western front is stabilized along Belgium
Stalin continues nagging the Germans for more favorable concessions with their Polish partition treaty.
In China the communists are getting stronger in resisting the Japanese.
To continue the war, and fight a long war at that, Germany is in desperate need of raw materials, and raw material shipments to Germany has shrunk to to well under 10% , which is below the German/Soviet economic treaty.
Stalin is smelling weakness now as German power fades.
As stated German operations in Norway and Denmark will be more limited than in otl and since the Germans are fast running out of time, they still haven't given up hope in knocking France out of the war. But ittl the Wehrmacht is less mobile than it was in OTL, fielding only 60% of the number of Panzers that they did in OTL. The longer the war drags France gets stronger, while the Germans grow weaker. As a result any renewed German offensives in France will be considerably weaker that in January 1940 ittl.
In otl when the German offensive began, the French airforce was caught completely offguard, being in the midst of an equipment overhaul, so the French airpower was virtually negligible. Ittl the allied victories have given the French ample time to revamp their airforce. Hence the French are able to deploy larger numbers of their fighter wings into the air. ITTL French fighters are a ubiquitous sight in the skies over the western front and in Norway. The French have also begun phasing out the less maneuverable Morane-Saulner 406s, for the more maneuverable Dewoitine 520s. In this TTL the Royal Air Force is also considerably much stronger, throwing in more Spitfires and Hurricanes into battle.
By 1941 the French have attained air superiority over the Western Front, Norway and Denmark. The Dewoitine D.520, gradually replaced the slower less maneuverable Morane-Saulner 406.
Background to the Sovier War:
In this TL Stalin started to press Hitler not long after the defeats in January 1940 and begins pushing for a renegotiation of their joint occupation of Poland.
Stalin is growing bolder in pressing the Germans and intentionally getting stingier over the shipment of oil and raw materials and needless to say tensions are high, its only a matter of time until Hitler invades the Soviet occupied area of Poland. Maybe around early summer 1941. Although the Germans have synthetic fuel, there's not enough to sustain the German war effort on a long term basis, especially when allied bombers begin raiding into Germany not to mention severe coal shortages. Even though Romania is selling oil to the Germans, the Romanians are hiking up the price. The Germans ittl are pretty much running on Romanian oil now, which the Germans are trading for polish military hardware. When that runs out, Romania is under threat of an invasion and mincing no words, Romania has threatened to destroy their oil fields if the Germans invade.
Hence invading Romanian to secure those oil fields is not even an option.
A trickle of oil from Romania does still continue to flow, but in exchange for more sophisticated military hardware like the Czech build 38T tanks and German ME 109 fighters, which adds further strains on Germany’s own war effort.
The Romanians in turn are selling spare parts of these military equipment to the French, who in turn are using them for their own captured 38T’s which comprise a good number of their light armored divisions.
Another failed German push into France will be the straw that breaks the camel's back for the Army also around 1941 before the soviet war begins. Army officers will try to kill Hitler.
Unable to push into France through Belgium, Hitler decides for a more direct push, through the Maginot Line. Naturally and with good reason the Army is reluctant to take on this formidable fortification. Hitler being his old self, argues with and berates his field commanders and is adamant in pushing for an offensive through Alsace-Lorraine. Hitler's grip on reality is unravelling faster than in otl.
For the Army the prospect of an idiotic not to mention suicidal attack on Alasce-Lorraine is intollerable. Shortly before the soviet war begins a group of army officers attempt a coup-d’etat. This coup will fail as in otl but will come closer in killing Hitler by paralyzing him from the waste down.
The failed coup will result in a soviet style purge of the German army in which several hundred officers will be rounded up and executed, while a few hundred will be sent to the concentration camps with their families. However, around 200 Heer officers managed to escape by sucessfully defecting to the French lines along with key abwehr officers with valuable intelligence which compromises months if not years of German war plans; A few escaping to Switzerland.
The subsequent Nazi purge of the army will naturally result in a brain drain for the Wehrmacht as this means officers will be appointed more on loyalty to the regime rather than competence. The traditional Prussian General staff will be hard hit by the Nazi purge ittl, particularly those with aristocratic backgrounds because ittl a number of the Army officers implicated come from old Prussian aristocratic stock which hitler iotl distrusted. The long series of frustration with the war effort, his loss of grip on reality and the failed attempt on his life finally drives him over the edge in purging Germany of aristocrats and Catholics. In this respect, the purge of 1941 is worst than the Night of the Long Knives of '34.
With the purge complete and a reshuffling of German army leadership, Hitler gers his wish and the Germans launch an attack through alsace-lorraine. As expected the Germans bash their brains out at the Maginot with atrociously high casualties producing only marginal victories at best.
After a failed German coup that resulted in a thorough Nazi purge of the Wehrmacht, the German
attack on the Maginot line commenced in the summer of 1941 resulting in extremely high German
losses. The attack was deviced by Hitler after a series of failed offensives through Belgium. Here Nazi
troops attack a section of the French fortification. Entire German platoons, companies, and regiments
were wiped out in the attack which produced only marginal victories. The Germans were later forced
to withdraw.
Also in the summer of 41 the French achieve air superiority; the luftwaffe is simply unable to get enough planes into the sky, hampered by lack of fuel and the crumbling German economy.
Hitler is now confined to a wheel chair but still holding out hope of winning the war, and he believes he can do it by invading Poland. Poland afterall contains a reasonable amount of oil fields enough to buy the Germans time and supply the German army which is now running dry.
Although this is true, there's just one problem. those oil fields are within Soviet-occupied Poland and taking those oil fields means adding Stalin to Germany's ever growing list of powerful enemies. Hitler on the other hand is convinced Stalin will attack him soon anyway, and so decides to preempt him.
Maybe around September or October Hitler hurls what is left of Germany's mechanized forces in an all or nothing gamble with s surprise attack on the Soviets in the southern half of the Polish front.
The stunningly rapid German offensive catches the Soviets completely by surprise, even more so than the Barbarossa operation of otl. The sucess of the German operation in Poland ittl has to do with the fact that unlike the western allies, the Soviets have continued to scatter their tanks among the infantry, learning the wrong lessons from the German defeats in France earlier in the year.
Veteran Panzer divisions from the western front encircle a huge number of Soviet Troops.
The collapse of the Soviet forces in Poland was so quick they didnt even have enough time to destroy the oilfields and they fall to the Germans completely intact.
The German offensive in Poland in 1941 caught the Russians completely off guard
The Germans were able to demonstrate the full capability of combined arms operations
against the Russians, who still scattered their tanks widely among the infantry. The result
was a quick Soviet collapse in Poland.
The soviets are still reeling from the German offensive, when the Soviets hastily regroup for a counter-offensive in the hopes of rescuing their trapped armies.
The Russian counter attack will come from northern Poland through Lithuania and into East Prussia.
The shocking success of the German offensive in Poland jolts the Romanians into being more forthcoming with oil. Hence fresh Romanian oil reinvigorates German panzer divisions enabling them to inflict heavy casualties on the Soviets.
At the same time however, the Soviet counter attack also inflicts losses on the Germans who could ill-afford to replace their valuable panzers. In any case the Soviet offensive is halted.
Stalin, absolutely livid at having been betrayed, demands an alliance with France and Britain. Stalin, summons the French ambassador in Moscow and demands the French launch a major offensive into Germany.
Even though the French and British politely meet the Soviet ambassador in Paris, there are those in the french and British government who would rather watch Russia and Germany destroy each other, while others who view the Soviets as the greater threat to Europe, would rather the Germans win the Soviet War. French communists on the other hand urge the French government to rally behind the Russians....
