Retaking of Calces

The Retaking of Ptah was an Imperial castigation campaign carried out by the Zero Legion Space Marine Chapter against invading forces of Orks to retake the lost forge world of Ptah.

History
The Zero Legion sends the 5th, 8th and 19th Division to aid the Adeptus Mechanicus in taking Ptah, a lost Forge World under the rule of an Ork Warlord named Krunchmetal. The Zero Legion launch a swift bomb raid on vital areas or places with large numbers of Orks, causing devastation to the Greenskins' ranks. Afterwards the three Divisions release large numbers of platoons and squads along with Skitarii. The battle takes over three weeks, but the Division makes good progress on cleansing the Orks from Ptah, thanks to the Tech-Priests and their knowledge the planet's layout.

Near the end of the campaign, Krunchmetal appeared, ready to kill the Division Commander that led the campaign, assuming he was like the rest of the Space Marines he has faced. However, instead of facing him in outright battle, the Division Commander had Sicarian Ruststalkers dispatched to eliminate the Ork Warboss and his Nobz, backed up by Scout Marines, Devastators and Tactical Squads. The ambush was swift and Krunchmetal was killed along with his officers. Additional Tech-Priests soon arrived to help bring Ptah back to life and into the Imperium's control, while some Zero Legionaries stayed behind the clean out the Orks completely.
