The warring sides were zirrian's tekkmen mob with truck and mech led by commander Pedro (si senor!) and my ork horde with additional centaur mercenaries.
First turn, my various forces sprinted towards zirrian's and first blood was made by my awesomeosaurus-mounted ballista.
This was followed by 2 other casualities from the tekkmens.
In return, my centaurs suffered some damage, and on was taken down by the sniper.
zirrian's mech marched to set my boys on fire... which he ultimately failed at the damage roll. As a response, my orks smashed the mech's leg, which fell over and ultimately became useless for the rest of the battle.
zirrian's rollings were quite rhapsodic: for example he managed this monstrous amount of damage with his longrange squad:
As it was all focused on one centaur, easily overkilling him.
On the other hand, a combined attack of 3 wasn't enough to scrath another horseman.
S'more bloodshed went on when finally Pedro (si senor!) was deployed and massacred another centaur.
The orks surrounded the tekkmen killing some, and critting one out of existence with a ridicolous amount of damage (the first of many).
Overwatch so far, minor losses on both sides.
The trucks chaingun suddenly malfunctioned and broke.
The truck relying on his momentum rammed his way through. The centaurs bailed off, one of them critting a length of 11" (and fell off the bed were this took place. note: from now, we'll play only on ground).
Again an obscene amount of damage...
With which my centaurs were annihilated for good (note: zirrian is a poser).
Meanwhile on the right flank, men and ork valiantly fight each other, havin small losses so far.
My orc hero attempted to leap in and carnage the guardian's (guys with spears), but failed and just fell in, koncking himself out for a round.
Trolls engage! Critting a shoota out of existence again.
The other troll kindly bashes the remainders of the left flank into pulp.
The tekkmen on the right flank begin to diminish... (or how is that spelled)
Ambush! The orks realize the ranged guys oppose greater threat so they march and kill some.
The shooters fire into the orks, butchering nearly half of them.
Pedro (si senor!) guns down an ork.
The guardians obliterate the survivors of the right.
The battle rages on, taking his casualities...
The ork hero gains conciousness, getting into berserk rage, but slays only one guardian.
A volley of arrows decimate the guardians.
Double kill! The ballista takes down two men on the truck. The driver got off to fight but met his fate by the troll's club.
The Overwatch of the extremly chaotic war.
A combined blast takes down the troll, who squishes a single tekkman.
Pedro (si senor!) guns another ork.
The ballista owns 2 tekkmen on the right.
The remaining troll clubs down 2 shoota.
Even I don't know what going on in this picture. Bonus: where's Waldo?
Tragedy! Ork hero is slain by a guardian!
Revenge! The guardian's are finished by a rain of arrows.
The troll mauls the last shootas.
By this point, zirrian's men we're only 4, causing individual losses with well-done shots. Pedro (si senor!) suddenly realizes this battle is lost and does the most logical, yet cowardish movement a commander could ever make:
Surrender!
The battlefield. Thrashed and littered by dead bodies.
The remaining four tekkmen were chained up and taken away as slaves.
Ork victory! WAAAGH!
I hope you had some kind of inventory going, 'cos getting all of your
