The paladin pulls up the horse short of the spears, though a bit closer then the halfling(s).
Holland starts to run, on foot, towards the paladin, followed closely now by the dwarf (and the other halfling, perhaps).
The three orcs, seeing that their trap had been sprung, unset their longspears, and charge the paladin! One of thier spears embeds itself into the horse, who screams, another screaches off of the paladins armor, and the last also finds it's path to the horse! THe horse rears at the suddon pain and starts to fall!
(I'll need a ride check!)
