Fourtheden Castigation

The Fourtheden Castigation was an Imperial castigation campaign of vengeance carried out by the Angels Herald Space Marine Chapter against the vile Sons of Damnation Renegade Chapter for the losses they sustained in a previous campaign.

History
The Angels Herald finally saw an opportunity to strike back at the Sons of Damnation, launching a vengeful assault against the Renegade Chapter to avenge their fallen Battle-Brothers who died during the Malphi IX campaign. After four decades of silence, the Sons of Damnation had finally revealed themselves, when they raided the Imperial world of Fourtheden. Their goal was to acquire more slaves for their gruesome experiments. The Angels Herald were a relatively young Chapter, impatient to mete out their anger against the vile renegades, and so, the loyalist Chapter wasted no time in launching a planetary assault.

As the majority of the Chapter deployed to the capital city to prepare it for the inevitable assault, the elite veteran 1st Company and 8th Assault Company led the spearhead assault against the Chaos army, creating a thin cordon between the capital and the approaching horde of daemons and Chaos Cultists. These valiant defenders harried the Forces of Chaos, buying time for the Imperial forces to adequately prepare the city's defences. The Angels Herald stood shoulder-to-shoulder, orchestrating a valiant defence that stopped the Sons of Damnation's assault. The brutal battle rage for two weeks, until finally the Forces of Chaos managed to make a breach in the city's defences, and soon the heretic army poured into the city.

Reinforced by the Chapter's war machines, the Angels Herald advanced upon the enemy. The ferocity of the Angels' counter-attack drove the Forces of Chaos into a hasty retreat. In the ensuing chaos, the Sons only managed to spirit away 100 Imperial citizens - a small price to pay, as billions more were saved, due in no small part to the valiant efforts of the Angels Herald. Sustaining few casualties and driving the Forces of Chaos from the planet, this campaign would go down in the Chapter's annals as a momentous victory.
