Battle of Vandrax 2: Crusade saved by Grey Knights

On 1811.017M42, in the early hours, the Grey Knights landed en masse in the main settlement on Vandrax 2. Conditions for their landfall were marginal, but through a superhuman effort the elite astartes landed and brought death to the loyalist and eldar forces defending the settlement. They managed to secure key objectives, including the city's main power generator, stunning the loyalist general. Units were cut down by ferocious firepower and in close combat. The battle was turning in the Crusade favour.

However, not all was going well for the Crusade. The centre of their line had seen the mechanicum decimated by unfortunate explosions and in the forests the constant harrassment by eldar forces had seen the Volscian and Vostroyan forces close to collapse. However, it was in the city that the battle was finally decided. The grey Knights stubbornly held on in the face of massive return fire from the loyalist firebases, which now had the astartes in a crossfire. However, at a critical moment when the battle could have been salvaged for the loyalists, the eldar hesitated, apparently unsure as to whether to deliver the victory for the loyalists.

The hesitation by the eldar ultimately cost the loyalists the battle, and then the planet, as the Grey Knights secured the area long enough for enginseers to shut down the power to the city, and establish a teleport homer for significant mechanicum reinforcements. Within a week, the rest of the city had fallen, as realising the battle was lost, the eldar allies of Hathek's loyalists simply melted away.
