I've not had people charge into the water, but then again I've not fought many bridge battles, I have however had lemmings on my walls.

Not an enemy in sight, barely within bow range. I'm sallying out against a superior force (in both numbers and strength of units) and the bulk of my troops are in the form of re-inforcements, so under AI control (grrrrr).

So, I decide to play it safe and bung everything ranged up on the walls. The archers have a merry old time raining death down on the foe's, but I had accidently ordered my principals up there aswell. In the ensuing confusion of archers, javlinners and principals all trying to go up the same tower, the principals promply bunch up and start pushing each other off the walls.

At forst I thought it was enemy fire, and wasn't worried, then more died and my archers were finally out of the way and I saw them steadily pushing their mates off the wall, while not going in or out of a tower and not even attempting to man the walls. All in all they pushed nearly half the unit off to fall screaming to their death before they actually started obeying my frantic commands and came down by the much safer rout of the stairs.

I like this little feature, I'd seen units pushed off when fighting for control of the walls (Ladders are great) but this was the first time I'd had people pushing their mates off, the good old freidnly stab I see....
