The initial set-up:

Left off board:

=====
TURN 1
I won strategy and chose to activate the Spacecraft. The orbital bombardment came in on top of captPiett's blitz, whiffing on just two Rough Riders. The pin-point attack went on the Shadowsword Company's Commissar, inflicting only one wound.


The four dreadclaws came in along SL's front lines, probably too spread out in retrospect.

I elected to reatain, and summoned with the Retinue in the middle of the board, sacrificing the Champion and summoning a Greater Demon and five Fiends of Slaanesh. I then rolled to assault the Stormtroopers, who blew their overwatch when I came running in. I lost both Noise Marines, much to my chagrin, and got seven blast markers for just running in. The assault didn't fare much better, as I proceeded to lose several of the Fiends, only killed one Stormtrooper, and lost everything but the Greater Demon to hackdowns. She retreated back to my half of the table with all of her wounds intact.



The SL Manticores attempted to sustain on the Chosen right in front of them, failed to activate, and elected to take the blast marker and just shot, getting a couple hits. The Chosen made their saves, however, and just took a blast marker for their troubles.

The pack of Hell Scourge doubled up to fire on the Stormtroopers, killing three. I then summoned and retained with my second dropped Retinue, wiping out the Sentinels.


SL activated a unit of Tbolts, choosing to ground attack the Chosen the Manticores fired upon earlier. They managed to kill one off, breaking the unit and causing them to flee into the woods. The Regimental HQ then engaged the Chosen left by themselves in the middle of the board, and it was a little bit of overkill, wiping out the Chosen taking a single casualty.



EC Land Raiders doubled to shoot and break the Stormtroopers, only killing a single Valkyrie.

SL Tbolts unit #2 came in and shot at my War Lord's Retinue, only laying a blast marker on the unit.

EC Hellblades came on, intercepting Tbolts unit #2, killing off one of the pair.

The Rough Riders failed a march order, and regrouped removing all of their blast markers.

EC Bikes marched, attempting to screen the Knight Pack.

The Mechanised Infantry doubled around the woods and shot on the bikes, killing one.

I attempted to double my War Lord, and had to regroup.

Shadowswords attempted to advance, thankfully just laying a blast marker on my Land Raiders.

The Infantry Company sustained on the Retinue that killed off the Sentinels, just laying a blast marker.

=====
TURN 2
I won the strategy roll, summoned seven Fiends on my Retinue, and engaged the Infantry Company. It was an ugly fight, and all but one stand was killed or hacked down.


SL advanced their Mechanised Infantry on the Knight Pack, managing to knock one off. He then retained with his Regimental HQ, doubling to shoot and kill five of my Bikes.


The Knight Pack sustained on the Mechanised Infantry, inflicting four casualties. The surviving Greater Demon from the ill-fated Retinue failed her advance, and regrouped.


The Shadowswords successfully advanced and killed three of my four Land Raiders. (Apparently I missed a picture of this, but the Land Raider tucked behind the buildings in the center of the table, by the Bikes)
My surviving Chosen advanced out of the woods, shooting and killing one Rough Rider.

The Manticores attempted to sustain, and had to regroup. (Apparently I missed a picture of this, too)
The War Lord's Retinue doubled, shooting on the Mechanised Infantry, and inflicted one casualty.

The single Tbolt shot at the War Lord's Retinue, inflicting two casualties.

I thought it would be a good idea to intercept the Tbolt with my Hellblades, and killed off the unit.

However, this would be to my detriment, Since the last pair of Tbolts would come in and take out two of my Hellblades.

=====
TURN 3

I won the strategy again, rolling a 6, and adding one demon to the pool. I summoned on my War Lord's Retinue, again sacrificing the Champion to summon in the remaining Greater Demon and a Daemonette. I then engaged the Mechanised Infantry, and won the assault. The lone Greater Demon then doubled up to shoot at the Regimental HQ, inflicting one casualty.



The Rough Riders attempted to march again, and were only able to move.

The Hell Scourge advanced on the Regimental HQ, inflicting three casualties.

SL Manticores sustained on the last Retinue, inflicting one casualty. The Shadowswords doubled, shooting on the same Retinue, inflicting another casualty and breaking the unit.


The lone Land Raider advanced and shot on the Shadowswords, inflicting 2 casualties on one of them. The Chosen then sustained on the lone stand from the Infantry Company, just causing it to break.


The Regimental HQ sustained on the Knights, inflicting 5 hits, laying 3 casualties, one-apiece to the remaining three Knights.

The remaining Hellblade stood down.
The Tbolts came in shooting the Knights, breaking the unit.

=====
TURN 4

I won strategy, and elected to have captPiett go first. He doubled his Shadowswords, killing the Keeper of Secrets, and breaking the unit. He then sustained on the Chosen, just laying a blast marker.


I activated the lone Keeper of Secrets, doubled her and inflicted just one hit on the Shadowswords.

Tbolts came on, shooting at my War Lord's Retinue, killing off my re-roll due to bad placement on my part.

My lone Land Raider advanced, laying a blast marker on the Shadowswords.

The Regimental HQ advanced, breaking the Land Raider.

The Chosen chose to marshal, moving and regrouping, but only removed one blast marker.

The Rough Riders marched (finally) to deny my Defend the Flag and They Shall Not Pass.

My Bikes advanced into the woods, holding my own blitz, and the solo Hellblade died to AA trying to bring the Stormtroopers to under half for the purpose of points.
=====
SCORE
Steel legion killed 1665 points
Emperor's Children killed 725 points.
A 940 point victory for the Steel Legion.
edit: I can totally do math.
