Be Animal Trainer. Stay in cover and wait for an opening.
You hang near the back row of swordsmen.
Aim rifle rifle at men operating one of the frontwards catapults, fire with archers
"Fire!"
The archers loose a volley of arrows at the men on the wall. You fire at on of the catapult workers, but miss and hit the catapult instead, doing nothing to it.
"Fire at will!"
Join an advancing platoon, shield raised.
My shield is unbreakable unlike sir's, right?
I'll upgrade it after this. Hopefully I can start free bashing soon.
your shield is unbreakable, yes, unless someone has a weapon breaking spell
"All units, forward!"
You march forward with your shield raised. You see another volley of arrows come at you and you duck, an arrow getting stuck in your shield. You march forward again.
"Ladder-raisers, coming through!"
You make way for a squad of men holding 5 ladders as they rush towards the wall. As they get nearer, you see a black cauldron being moved towards the edge. As t he ladder men reach the wall, the cauldron tips, pouring oil onto the men below. An archer steps forwards with a flaming arrow and fires into the men below, catching them all aflame.
"Send a second group in!"
Another squad rushes past you, and they reach wall. They raise 5 ladders, but one of them gets kicked down before it can be secured. A commander points to your line of men, which include swordsmen and a few men with axes.
"You all, climb the ladders!"
You rush forwards to the ladders.
