how do you beat chapter 10

Ok here you go!!!first select all of your units and put them in a circular formation.this will help you protect your archers!then make two different groups of spearmen and macemen and start sending them forward!the enemy will send down the rolling logs which will result in all pitches being set on fire.make sure your reserve main attavk force arent in there as they will burn down to toast and all youll be left with is your lord and some heavily injured troops.Ok so once you have got rid of all their traps and pitch start sending your laddermen forward along with your attacking force a little ahead of them.once you scale the walls select all of your force and start clicking on that idiot seren continuously!!!when they reach her shell be gone with the wind!!!ladies aint no match the huge swordsmen!!!! Done!!
P.s don't keep your lord away from your attacking force he will be a huge help in defeating seren plus sometimes those crazy knights go on a frenzy and start attacking him!!also that barclay is hardly any use in this mission!!!(boy are my hands dying to use slang)
