Breaking against the Iron Wall

 A couple weeks ago I once again mustered the Dark Mechanicum against the Solar Auxillia and their Astartes allies, this time with some Titans and Knights in the mix. We set on 2000 pts and prepared for an Armoured Engagement. We setup the board with more and more painted scenery, and some homemade roads:

The Loyalists with a Warhound Titan.

The Dark Mech with three Acastus knights, one of them an old Warlord Titan model which is tiny compared to the new titans now.

Seperos Overlords advancing on one flank.

While the Acastus Knight "Lord of Darkness" charges up the middle, and the twin Acastus Knight "Lies of Destiny" and "Shaitann" take the west flank.

Scintilax and Tenebrax and Errax stalkers ready to advance.

Supporting the west are some Krios tank (portrayed in this battle by some Malcadors).

The infantry swarrming around the knights' feet.

On the other side, the Warhound prepared to advance up the middle with the Baneblade and Stormhammer and Dracosan transports moved the infantry up the field.

The battle begins.

Rapier batteries with Quad Launchers garrison a building.

Using transports, the Ogryns advance and fortify a building in the centre before the Harpax swarms and Thallax infantry arrived.

The Darkness and stalkers advance in cover.

The Malcador Infernus and Valdor tanks lead the advance.

The transports allow the Solar Aux to move into position faster than the skittering Dark Mech.

Casualities beginning to mount.

Under heavy fire of everything the Orgryns hold fast.

Imperial fists holding the line at the rear to prevent any breakthroughs.

The Dark Mech armour bunches up.

The Dracosans prove to be useful after dropping off troops by cluttering the middle around my secondary objective of Rescuing the traitor Imperial First stand.

And Errax and Lord of Darkness assault the Ogryns but at unable to dislodge them and take damage in return.

The other Errax charged the Sentinels but the Solar Aux quickly counter charge.

The Ursurax garrison a building while the Arch Magos and Mrymidon Secutors take cover. The Krios tanks open fire on more Dracosans.

The Twin Knights open fire with the Mrymidon Destructors.

A Scintilax Overseer secures and moves back with the rescue objective while the Tech Thralls and Tenebrax try to provide cover fire.

The building the Thallax are in is rocked by demolisher fire as the loyalists try to destroy more buildings.

The Ogryns continue to hold the line as the Knight and Stalker are eliminated.

The board is looking mighty empty on the Dark Mech side.

The Arch Magos and his Secutor bodyguard try to kill the last Dracosan transport.

The Ogryns charge into the Tech Priest and his Tech Thralls to prevent the rescue objective from being taken.

The Warhound and Baneblade and Stormhammer continue to pummel the Dark Mech lines from afar.

The Thallax detachment jumps in to try and get some high AP fire into the flank of the armoured column.

The Ursurax assault troops make their charge on the far west flank.

The Krios tanks fire their lightning cannons into the Sentinels.

The Warhound denies your advance and substitutes its own.

What you don't see here is the Serperos Overlord stalkers because the Leman Russes and Malcadors eliminated them.

As the Warhound and Space Marines stop the Dark Mech push, I conceed the match.
