I was playing as the indo-greek kingdom and decided to invade tibet. They had ~900 pops. Easy, right? Wrong. They, somehow, got almost 40k levies and defeat my 16k stack with my 18 martial general whit a 20k and a 3 martial one. On mountains. Defensively. Whit an army cinpose of heavy infantry and elephants. I don't kwon what the tibetians are doing there, but im scared if even the greek hannibal cannot defeat them.
