1430 - 1431 : Scotland !
In early 1430, it was time for me to look at the overall situation. I do not have strong competitors left able to beat me on one on one anymore. However it doesn't mean the task is finished. I rule on about 1/3 of France. I still have to at least vassalize or to conquer most of France AND conquer/vassalize Scotland to accomplish my goals before 1453. Looking at my infamy, this is simply impossible. If I try to conquer everything in the next 23 years, I'll see a coalition of every single European country or State at war against me.
However I can at least destroy one threat really easily. The regency council gave me the mission to vassalize Scotland, and it seems my King do agree.
Scotland will then be my next goal. And this sounds really logical, as the Scotish signed an alliance with the Valois and Aragon. I do not know which side Aragon would take if there were a war between Scotland and England, however I know that I still can't allow to see the Valois and Scotland allied.
In april 1430, the perfect occasion happens. The Valois and Aragon declared war against Guyenne. As they will be busy for some weeks, launching my attack against Scotland would be the perfect time.
That said, on april 30th, I officially declared war to Scotland, with all my troops stationned in France. After all, there was the most probable threat.
Aragon decided to end our alliance, but did not declared war on England. The Valois however did. My plan was now obvious : crushing the Valois as fast as possible and then sending my troops in Scotland.
By October, Valois resistance around Ile de France was entirely crushed. It was time to split my armies in two parts : half would go back to england to fight the Scotts, the other half would go south to fight in southern France the remaining Valois forces.
In the end of 1430, it was obvious the war was won. It was just a matter of time before the final victory.
Next to this war, the Bourguignons finally signed peace with their ennemies. They only had 4 territories owned, all of them in revolt (between 19 to 25% of revolt risk for all of them, even their capital !)
The year 1431 was mostly about taking control of cities. By December, I finished to crontrol all of them and then was able to sign peace treaties.
