A boulder hit the wall, and demons poured down from the wall like autumn leaves...
A well-aimed volley from the ballistae and the Priests of Arkat covered the retreat of the cavalry from the arriving demon reinforcements, but there were clearly more demons on this side of the wall than there were dwarves...

Everyone on this side, what are your actions?
