But for some reason - perhaps superstition around repeating what happened in the Great War - Germany did leave Belgium alone. It was still a near-run thing, as the French did not mobilize enough troops, and Canadian reinforcements were frantically switching between helping defend the Alps against Italy, and the Maginot Line against Germany. Italy nearly broke through, and at one point Germany did break through Maginot. As Canadian forces scrambled to contain the breakout, another stroke of luck happened - Switzerland declared war on Germany, and occupied the part of the Maginot Line that France had failed to defend, trapping the Germans who had crossed it. France survived, but barely.
In June of 1940, the Soviets declared war on the Germans, who had quickly conquered Poland, Denmark, and Norway, but were experiencing some difficulties against Sweden. The Soviet "they look like they're in trouble if they can't handle Sweden, let's finish them off now" strategy didn't work quite as planned, and by the next year, the Germans were approaching Stalingrad, where their momentum was stopped, with Leningrad controlled by the Estonians and Finns. But this also meant they had weakened the garrisons at their West Wall, opposite Maginot, so I decided to test their defenses with the (entire) Canadian Army in the spring of 1942.
Somewhat surprisingly, the result of the test was that Canada could push Germany back. And back some more. And some more. We went in a generally northeastern direction, up to Hannover, then taking the Kiel Canal and into Mecklenburg, over the course of two or three months. The culmination was the capture of Berlin by Canadian forces on June 20, 1942.
This was not, however, the end of the war. It took a while for the Germans to disengage in the east, but that summer their troops went west in a big way, re-conquering the occupied lands west of the Elbe (Hamburg), conquering the Netherlands, and threatening to break through Maginot once more. Canada was forced to bail out France once more, leaving a perilously small 14 divisions in control of northern Germany, which were forced to retreat from Berlin in September. But with France re-stabilized (and Luxembourg still valiantly holding out, in a much more impressive showing), I was able to retake Berlin in October, just to lose it in November, before finally taking it for good by January of 1943. By that point, the Soviets were getting back in gear, and over the course of that year, the British and Americans would arrive in force, ensuring ultimate victory in Europe. Canadian troops from France would help liberate Austria and Bohemia via Switzerland, meet up with the northern contingent around Dresden, and then march east, liberating Poland, and ultimately conquering Estonia and Finland to end the European conflict.
But by then, Japan had conquered both China and India, the first time I'd ever seen that happen. Conquering China? Not that rare? Also conquering India? Very rare, especially a total conquest. They did pretty much entirely ignore the East Indies, including failing to take Singapore, so they had a lot of focus on India. But it meant that the amount of manpower that Japanese-allied forces now had access to was essentially unlimited, with the only limit being how quickly they could equip those forces. If they mobilized millions of troops from China and India as well as Japan? We didn't want to find out what would happen.
Canada's navy, however, could not take on the Japanese Navy. So, instead, I sent my troops to Oman, and with the British Navy keeping Japan east of Singapore, launched a naval invasion of western India. Much like the Canadian invasion of Germany, this met with immediate success, as it was totally unexpected. Moving as quickly as possible - and, like in real life, the Canadian Army was highly motorized - I managed to take the entire southern half of India before enough Japanese reinforcements arrived to stop the Canadian advance. By then, British and Swiss troops were reinforcing my lines, and after some time to regroup, I managed to work my way up into Bengal, and eventually force the Japanese-allied collaboration government to capitulate. Pockets of resistance remain, where Japanese or Chinese troops control parts of India, but with each month, there are fewer such areas.
By then, I was planning my next move, an invasion of Siam. This, too, went well, if not quite as drastically well. Most of the core Siamese areas are now Canadian, and the diversion of Siamese troops helped the British advance north from Singapore, linking up with the Canadian vanguard. It's now abundantly clear that Japan has sent many troops from eastern Siberia, where they had been fighting the Soviets - initially highly effectively, less so recently - to southeast Asia, and Canada, being a relatively low-population, moderately industrialized country, is not pushing them back very much right now. But like against Germany, it also feels like only a matter of time until our British and Soviet allies wear Japan down, finish off the last Japanese pockets in India, and tip the balance in our favor.
As for America? Like Britain, they're island-hopping. The Americans have Saipan, the British have Iwo Jima. The AI is very bad at escorting troops across oceans, and the Americans have lost a humungous number of troops to Japanese submarines (they should also really send more destroyers to the Pacific). What would really make sense is if the British and Americans combined naval forces, defeated the Japanese navy, and invaded the Home Islands, but I don't really expect the AI to pull that off quickly, and the Canadian Navy only has about 11 ships right now, so I can't impact the naval situation to any degree (my original navy was sunk by Germany).
All in all, it has been a satisfying campaign. Mainland Canada is completely undefended, except by the size of the Pacific Ocean, and my policies have very much not been in alignment with real-life Mackenzie King, who was very hesitant to institute a draft even late into the war, as well as to send Canadian troops overseas. In real life, the Canadian Army had not won a single battle by early 1943, largely because it had only fought two battles since entering the war more than three years earlier. But my "could Canada have made a difference on the battlefield?" experiment seems to have been answered in the affirmative, and I learned some Canadian history along the way.
I may well not finish it out; I rarely do, usually only playing either the European or Asian theater, depending on where I start. The fall of Japan, playing as a non-naval power, tends to be a disengaging affair, and I'm surprised the Indian and Siamese campaigns were as interesting as they were - thankfully, neither resulted in the Canadian Army being destroyed at the landing beaches. Playing onward from this point seems like mostly a formality, something that would be unnecessary if the Americans knew how to use their fleet.
