Battle of Solis Planum

The Battle of Solis Planum was a colossal battle on Mars that saw both the Secessionists and Mechanicum simultaneously attacking the last major holdings of the Imperialists on Mars.

Defending the center the Imperialists were composed of Thousand Sons, Salamanders and Iron Hands with supporting elements of Solar Auxilia, Imperial Fists and some renegade Emperor's Children. 

Attacking from the north were the forces of the Mechanicum.  Comprising of a Reaver Titan of the Legio Astraman and attending Knight House, Skitarii Legions, a considerable Legio Cybernetica cohort and a small force of Raven Guard. 

From the south cam the Secessionists composed primarily of Iron Warriors and Imperial Militia, lead by a contingent of Ultramarines and supporting elements of the Alpha Legion.

The Salamanders and a small contingent of Iron Hands Held off the Mechanicum in the north.  Vulkan and one Iron Hands Veteran Tactical squad destroying almost all of the Knight Titans, all the while the Reaver Titan bombarded Vulkan whilst all watching saw him walk unscathed from the God machines hellish firepower. 
The bulk of the Iron Warriors, Thousand Sons and the supporting Imperial Fists and Emperor's Children tried to sally forth in the south smashing into the Secessionists whilst the Reaver randomly bombarded both sides from afar.
The defence in the center was disrupted somewhat with the Raven Guard dropping virtually their entire force in the middle of the defenders throwing their defence into disary. 

Ultimately the defence held, with Imperialist forces taking massive damage but seriously bloodying the noses of the Mechanicum and Secessionist forces.

Due to this game having taken place some time ago, and me only having 4 pics and my terrible memory to work off of I will give a few highlights I remember.  If people have any fond anecdotes they want to add in then please do so in the comments below.

Here are a few of my highlights:
-The Raven Guard Moritat being killed by the Scattering Raven Guard Deathstorm Drop Pod, before he had fired.
-Vulkan surviving every shot the Reaver fired his way and merrily beating down Knight Titans.
-The Defenders leaving their entire center open with a Raven Guard Drop Army waiting on the wings.
-1 Iron Hands Veteran Tactical squad killing 2 (or 3 I forget) knight Titans in close combat and only losing less than half the squad total.
-The crazy amount of armoured firepower that the Secessionists had.
-The Secessionist hill well away from the front line ,with the Ultramarines command squad and Lascannon toting Iron Havoks on it getting bombarded into oblivion by orbital bombardment (2-3 orbital bombardments I think).
-The crazy number of Dreadnoughts on the table (from the pictures I can see 29 but I think there may have been a few more)
