Yikes, just hit an Ulm army of over 500 with at least 100 Ulmish HI

Granted the rest was LI and short bows (there were maybe 20-30 x-bows), but those 100 HI were enough to wipe out my front lines of swamp gaurds and a handful of wights...
I might have won due to my superior mages, but a lucky couple volleys of x-bows killed off my two best marsh masters (read equiped

), and then I started routing like crazy! I had zerked serpants trying to get to his rear, but there were too many LI in the way and they got bogged down and eventually killed, though they did a fair amount of damage to the rear of the LI mass.
This was around turn 30, and we had both moved in on the same undefended Abysia province. I was hopeing to get my prophit down with his serpent army (~25) before tackleing the Ulmish hoard. As it was he smacked my main army pretty good, and I had to hunker while I moved more mages down to replace my losses. I lost all my undead too, so I'm not sure if I'll risk him again. He lost ~300 units, but most were the chaff, I'm sure he'll build them up again quickly
Anyway, as others have noted, Ulm had a damn temple in every province I could see, so I was having trouble pushing my Miasma on him, even after I freed up the cash to start pumping temples everywhere I could get a cheepie priest.
