Dulma'lin Cleansing

The Dulma'lin Cleansing was a year-long campaign fought by the Catachan II regiment under the command of Colonel "Iron Hand" Straken. It mainly occured in the Ork-infested cavern network of the planet, where the Catachans used guerilla tactics to wreak havoc amongst the Orks.

At one point Straken's men became the target of their own ambushes, slain by a seemingly cunning and stealthy Ork in the Warbosses employ. The infamous Kommando, Snikrot engaged Straken in a brutal dual, eventually being defeated and grievously injured.

The breaking moment of the campaign was the infiltration of the main Ork settlement in the Mommothian Vault by Straken and his demolition experts. They managed to stay undetected for 3 days before Squighounds finally located them. By then however, it was too late, with the team having laid explosives on the cavern's support stacks, while Straken himself fought off the Ork horde, killing no less then 30 of them and wiping out a Killa Kan mob before dragging the Warlord Killzkar beneath a Squiggoth, who trampled them both.

Incredibly, the demolition team managed to pull their Colonel's body out from the cavern, Sly Marbo personally carried Straken to safety, just before it collapsed, destroying the entire settlement beneath. The Colonel's body was patched back together and he was redeployed to the Ulani system with his regiment, while the High Praetor Osh'preen arrived two days later with reinforcements and easily finished off the now-leaderless Ork horde, taking all the credit for himself and becoming the planet's Governor, whilst claiming the Catachan's were cowards who had hidden for the duration of the campaign. A statue of Straken was erected by those citizens who remained both loyal and thankful for the Catachan's aid.

Two years later, the corrupt and lax reign of Governor Osh'preen opened the way for a heretical uprising by the Slaaneshi Cult of Frantic Flensing. The Catachan II were the only regiment close enough to offer assistance but, thanks to a mysterious series of communication failures that bedeviled the Catachans, Osh'preen and his corrupt government were left to their remarkably horrible fate.
