... Which is shorter than you'd expect.
The setting. The imperium has 3 scout in sniping positions. The orks have the viking ultra-mega shooting thingy, which can be fired twice and I used manual fire (which will be very important later on).
The human's objective was slaying the Ork hero, while the ork objective was simply annihilating the enemy.
Imperial Strike force swordsmen, archers, warmachines and a flyer armed with 2 bombs led by Niol, the Force commander of the Empire.
The orks, led by the Warboss who besieged Castle awesome a couple of weeks ago. Relying on brute force and the massive missile launcher, these vile greenskins are eager to krush kill and destroy.
The battle begins... after rolling three ties for initatives. Lol.
So, the orks start, round 1:
The launcher fires, taking out 3 archers, the other failed to deal any damage.
All except one troll began to march towards the enemy, one of the scouts were shot down.
The ballistae kills a champion and 2 regular orks.
Besides that, they just simply advance.
Here's the most awkward/awesom thing that occured in my whole wargaming career:
The launcher fires and hits the flyer; because of manual fire this counts as a hit.
The flyer then fell and crashed into the middle of the orks.
Because of the fall damage the engine blew up and ignited the two bombs too... the result is 27 damage in 6 inch radius.
Two squads, the ork hero and the nearest scout were all blown to bitz.
Since the empire managed to complete his objective first, it's Imperial victory; the remaining orks, scattered and confused, flee.
P.S: I didn't made this up, this is how it happened. I still found it rather weird.
