Orks vs Chaos Space Marines with Daemon allies Picture Batrep!

This one's a really old batrep, so I've forgotten a lot of details I'm afraid.

Anyways, it's my beloved Orks against my buddy Caspers Csm+daemons!
On the top picture my lootas (burnas standing in as lootas, anyway) take up a pretty darn good position for raining dakka on the enemy.

The oh so brave Word bearer chaos space marines form a konga line behind their leader in his rhino as they begin the approach towards the Ork line.

My, at the time, only primed Ork warbikers dash out, coming near an archeotech ruin, triggering some toxic defence system that kills two bikers and puts a wound on the nob!
He then redeems the blunder somewhat by sniping the csm champion in the konga line with his dakka gun.

My boyz pour out to respond to the nasty threat of the Chaos, gleefully cheering as it looks like it could be a good scrappin' ahead! 

Pink horrors appear from the warp to join the fray, next to the herald of Tzeentch! ...

three flamers of tzeentch also materialize, but they do so next to the unit of boyz. Luckily they scatter and so their disgusting flame attacks don't do as much damage as they could have.
My warboss and Nobs decide to jump out the looted tank and mow down these pesky daemons before they cause any serious harm to my boyz.

the Chaos space marine Rhino approaches as the Nobs and warboss slay the Flamers. But as they're about to hop back into the looted tank...

The driver decides to Press dat'  and drives off, right into the main body of the enemy army. It is immediately destroyed on the csm's turn.  This is also really bad because my warboss was wearing Mega armour, giving him a 2+ save but also the Slow and purposeful special rule.

instead of charging into the soft and squishy (and very shooty!) Pink horrors, my warboss now has to fight the Warlord of the word bearers in a challenge instead!

My warboss slay the Chaos lord in single combat, only to be assailed with the combined firepower of the pink horrors and the chaos space marines.

The nobs slowly get whittled down from the shooting and the close combat that follows.
But the warlord stands firm, killing pink horrors and traitor marines left and right!

all by himself versus both marines and daemons? Not a problem if you're a super badass Ork warboss!

He actually kills them all eventually! He would probably had died if it wasn't for the brave warbiker nob who managed to kill the csm champion who had a powerfist, earlier in the game!

WAAAAGH!
