All right, so I'm playing as Prussia. I own lands from Friesland to the Memel. I had declared war on Luneburg, and called in their ally, Brabant...
...Except I had a truce with Brabant, something I had not noticed, increasing my AE exceptionally.
Over time, a coalition formed, and they declared war on me, calling in France, the Netherlands, Switzerland, the Hansa, Utrecht, and a few other countries.
My army of 50k, and the armies of my vassals Luneburg and Friesland, along with the armies of my ally Great Britain, aren't as large as the coalition army. France has seperate armies as large as mine.
How the fuck do I continue unscathed?
