Sure, but you can always disband units that are costly or sub standard. Hell, you can send them off on suicide raids too if you'd like, too many troops is a problem I like to have!!

High loyalty generals or large army stacks hamper this approach though. A high loyalty general with a decent army can be severly expensive, far more than you'd recoup by selling the provinces buildings. Unless you have money coming out your ears, in which case you can more or less buy the destruction of an enemy province with a couple of emisarries

In truth this strategy would be tough to pull off consistently, but it does provide an excellent alternative method of acquiring a province. Does this incur a warning from the pope? I always thought emisaries were a bit of a waste of time, but I guess not - they can actually be a very potent weapon. Pity spies can't do this too.

By the way, I've now taken all of the Egytian provinces except for Arabia. The Egyptians just keep retreating and giving away their provinces to my rolling horde. I'm now at war with the HRE, Turkish and Swiss who have discovered that I'm the single greatest power in the game and are trying to take me down. None of these are a real threat though and as long as the Sicilians stay out of it so my navy doesn't suffer, I should wipe the floor with them pretty rapidly.

The HRE dropped a stack that out numbered me 2-1 in my captial city of Denmark, but I mauled them mercilessly. I killed/captured 740 and lost 36. It should have been a pretty close battle. They had stacks of Arbalesters and Pav. XBows, a couple of units of cavalry and a few units of Halbardiers and spears to use against my Chivalric and Royal Knights. Unfortunately for them, they approached in a bad formation and I was able to flank them with CMAA's and run down their mass of archers with my knights in an appaling mismatch. The rout was on moments after the forces engaged and my horses chased them all to the map edge, stopping to crush and regrouping units. It's possibly the best result I've had so far.
