In Finland the invading Red Army suffers catastrophic casualties, while in China the Nationalists are divided as Japan uses diplomacy to strike back.

After the chaotic invasion and catastrophic losses of the first weeks of the Winter War, the Soviet Army has learnt their lesson. Further west the Wehrmacht is ready to move, as long as the skies stay clear.

As the Winter War rolls on the only help the Finns are getting are from volunteers. The Western Allies still have their thoughts on Norway, little do they know that the Phoney​ War almost ends this week...

his week shows the Allies first attempts to break the German Enigma code. Meanwhile, the German war economy shows some flaws and the Soviets are massing artillery in an effort to break the Finnish defences. As the Winter War rolls on the only help the Finns are getting are from volunteers. The Western Allies still have their thoughts on Norway, little do they know that the Phoney​ War almost ends this week...

The Soviet forces revive their winter offensive this week. More men, more tanks and more artillery are brought in to try to force a breakthrough in the Finnish lines. Meanwhile, Churchill encounters resistance to his plan to cut of the German iron trade with Sweden.

After more than a week of preliminary bombardments and attacks, the Red Army finally attacks the Finnish defensive positions on the Karelian Isthmus en masse. They throw thousands of troops at the Finns at the entire width of their lines, even exceeding them. The Finns defend the best as they can, but their winning streak seems to come to an end.

German Genral Erich von Manstein has a cunning plan. And as it happens, it's just how Hitler likes it. This week, the German war plans change quite drastically. In the meantime, the Soviet Red Army continues it push through the Finnish Mannerheim line, except for a stubborrn Finnish pocket of resistance at Taipale.

The German plans for the invasion of Western Europe start taking shape. Mansteins plan is innovative, bold and controversial, but Hitler likes it. If everything goes according to his plan, the Germans will be celebrating their victory in Paris come spring.

The French promise to send troops to aid Finland, though the majority is planned to go to Norway or Sweden. In return, the Finns postpone their peace talks with the Soviets. It is at that moment that the Finns realize that the French are playing tricks and the Soviets are not to be messed with. It's deal or no deal, and they need to decide quick.

The Winter War is over. The Allies tried to stall the Finns for as long as possible to justify their invasion of Norway, but the Finns have had it and don't trust the British and French to come to their aid. This week, the Finns sign a peace agreement with the Soviet in Moscow.

French Prime Minister Daladier overplays his hand and is replaced after his vision regarding Scandinavia wasn't widely shared in the French parliament. Meanwhile, the French and British in France are preparing for a German attack. If Hitler gets it his way, they will also have to prepare for an attack in the south as Hitler tries to persuade Mussolini to join his invasion.

Newly appointed French Prime Minister Paul Reynaud and his British counterpart Neville Chamberlain spend the week looking for ways to harm the Germans. Not just by targeting their direct opponent directly, but also by exploring the idea of expanding the war into much bigger territory. In the meantime, the French prepare for the expected invasion and the Allies are laying the foundations of what might one time become a weapon of mass destruction.

While China gets a new government, or at least in the eyes of Japan, the British are trying to cope with the rationing of meat and dairy products by trying out some new recipes. More importantly, Germany seems to be very serious about invading Norway. However, the British also plan to move closer to Norway.

This week, the Phoney War seems to come to an end when Germany invades Denmark and Norway. The Allies seek confrontation with the Germany in the hope to at least deny them full access to the Swedish Iron mines. Nevertheless, the Germans are prepared and have been planning this for weeks. It looks like it will cost a lot to put a stop to this.

The German Invasion of Norway is still very much in full swing. The German Wehrmacht is moving north from Oslo, where a Norwegian force is trying to halt them in anticipation of Allied reinforcements. The British do land in Norway, but don't necessarily rush to relief the Norwegian army. Meanwhile, Norwegian 'traitor' and 'failure' Vidkun Quisling rises to be the new leader of Norway – only to get rejected by Hitler again. Numerous powers are now trying to grab, restore or consolidate military or political power in Norway. It's a mess.

The Invasion and subsequent Battle of Norway has only just begun when the British decide to pull back. Poor planning and misfortune after misfortune harms the British campaign, which becomes very apparent this week while the fighting continues. Almost everywhere, except for in the far north, the Allied troops pull back under heavy German pressure.

Allied plans to take Trondheim in Norway to allow for larger reinforcements and even bigger aerial support to come in are disbanded as the troops approaching Trondheim are pulled back from Norway. While the Allied efforts in Norway lose force there, the Allied forces in Western Europe are prepared for a German invasion through the Benelux countries. The Japanese too are determined to continue their campaign in China, and send thousands more young men into the battlefields.

As the Allied troops in Central Norway are evacuated and the Norwegian troops there surrender to the Germans, the Allied position around Narvik is still quite strong. With the addition of roughly 5000 Polish soldiers, the French, British and Norwegian force will prove to be a formidable foe for the Germans up North. This week however, the war drastically changes as not three but four Neutral countries are invaded. The Phoney War is ultimately over.

The German invasion of Western Europe has been going for over a week now, and the Neutral and Allied countries are in disarray. The Netherlands, despite putting up fierce resistance on some occasions, faces overwhelming powers while Belgium, France and the British feel the pressure from an organised and armoured assault from the Ardennes. And still, the German tanks, soldiers and aircraft are not all the Allies have to fear, as many of their losses are caused by their own command.

While the massive invasion of the Benelux countries and France was going down last week, things were also developing on the fronts in Norway and China. But this week, the German beast is let loose. After breaking through its cage at Sedan last week, nothing seems strong enough to block its way to the English Channel. And if one thing becomes clear, it is that the Allied command structure and the way they communicate is one big smoking mess...

When the Germans Panzers move north from Calais, the British Expeditionary Force and France's soldiers still fighting in Belgium and Northern France are trapped between a numerically superior German army. A big operation code-named 'Dynamo' is set up to evacuate as many as possible from Dunkirk.

As the battle for France is still raging but looks like a ringing victory for Nazi Germany, and the encircled troops in Dunkirk have been evacuated, will Great Britain remain in the war? If so will British forces remain in continental Europe? In fact will Great Britain even be able to remain an independent nation, or also fall to the Nazis?

The fighting in France isn't over, not even when Paris falls, as the Germans advance and Italy joins the fight. But the Brits now have their back to yet another ocean and see no option but out. Further east Stalin uses the chaos in the West as cover to start moving in on his neighbours.

While the fighting subsides in much of France, the Italians invade in the south, while tension continues to grow in the Baltic states as the Red Army increases its presence and the USSR makes plans for coups.

Hitler goes to Paris, while Stalin occupies more territory... but something is on Stalin's mind. News of the sudden success of the Wehrmacht in the West is not what he had hoped for. Churchill also looks to the West for help while a German invasion of the British Isles seems imminent. Far East the Japanese are on the advance.

The repercussions of the fall of France are not yet seen in full. But this week Britain makes it clear it isn't about to give up, even if it will mean some really hard decisions.

The Germans and the French in Vichy consolidate their newly acquired power as the British deal with the remnants of the French navy. The Battle of Britain begins with fighting above the English Channel, a battle with great consequences for the future of Europe.

Peace seems to slowly return to the European mainland, but not for long, as the Germans move their airplanes to the French coast to Battle Britain in the skies while they make invasion plans, and the Soviets are entering the Baltics after 'elections' invited them to.

Hitler searches for ways to force Britain out of the war, but the British sit safely behind their cliffs, their channel and their Royal Navy. Engaging the navy and invading Britain would require a major air-superiority. As a result, the Germans plan to knock the British out of the skies. This is the Battle of Britain.

As the Kanalkampf comes to a close, the Battle of Britain heats up. Hitler wants Britain out of the war. But before the Germans can invade Britain, it will have to deal with the Royal Air Force and the Royal Navy.

This week, the war spreads to Africa, when the Italians invade the British Colony of British Somaliland. While this might seem trivial, it might have tremendous consequences on the remainder of the war.

As the Battle of Britain reaches not seen before levels of intensity, one of the British colonies is lost to the Italians.

This week, the communists attack the Japanese in the Battle of 100 Regiments. Meanwhile, in Europe, the Battle of Britain enters phase three with the Luftwaffe actively targeting British airfields.

As the war turns one year old, there seems to be no end in sight. The Luftwaffe starts targeting civilian areas of London, the peoples of Eastern Europe switch country without moving houses, in occupied territory the population continues to be terrorized, and an end to the Chinese war that has been raging on for years now seems ever further away.

This week, the battle in the skies of Britain enters a new, even deadlier phase, as the crowded streets of London turn into a war zone. It is the start of the Blitz.

The Blitz continues as the German army seems close to the execution of Operation Sea Lion: The Invasion of Britain.

The Battle of Britain continues as planes fight over the South-English shorelines and large parts of London are targeted during the Blitz. However, this week the ultimate goal of this air battle is postponed. The invasion of Britain, Operation Sea Lion, is called off. For now at least.

This week, the factions of World War Two begin to crystallize as the Japanese join the Axis powers.

Hitler is trying to get new Axis Powers on board in his fight against Britain, promising them all huge territorial gains.

The Blitz continues while Chinese Communists are fighting Chinese Nationalist in China. But the mass bombing of civilian targets does not really do what it is supposed to.

The World War seems to get bigger and bigger as Italy plans to invade Greece and the USA takes a stance.

Hitler finds out that not everyone is ready to do his bidding. Much to the frustration of Hitler, Franco, Petain and Mussolini all have their reasons to take the high road.

A new front opens up in Greece as the Italians invade, while the Battle of Britain seems to come to an end.

The Battle of Britain is finished, but the war is far from over. New German plans are being made for the Balkans and Greece, where the Italian offensive is not as successful as planned.

Japan has two wins this week, and one might turn out to be very consequential for the rest of the war. In the meantime, the British RAF fights the Luftwaffe and Italy struggles in their offensive against Greece.

As the Greek campaign continues, Hitler points his attention eastwards. While he can't invade the Soviet Union just yet, his dependence on it is making him nervous.

While Hitler consolidates his power in occupied France, Japanese and Italian forces try to get an edge, but fail. The war is not looking too well for anyone at this point.

Wilhelm Canaris once again disturbs Hitler's plans to drag Spain into the war, as the Germans finalize their plan for the Invasion of the Soviet Union which is scheduled for the summer of 1941. Meanwhile, the Greek counter-offensive into Albania loses steam and the Pope objects to the German T-4 euthanasia program.

The First British offensive of the War begins in North Africa. Meanwhile, the German Knickebein system is designed for bombers to accurately bomb British targets at night. This is what the Brits do to stop them.

What Adolf Hitler expects to be his Magnum Opus offensive is still 6 months in the future, but it's going to need plans and more plans. The British, though, are seeing success right now on two fronts far to the south.

Italy finds itself in a dire position in Albania as Christmas is celebrated in a war-torn Europe and fighting continues in China.
