Carcharadons prevent major Zadoc offensive

In early 02.014M42 the Imperium became aware of a build up of chaos troops in the cold southern tundra region of Mida. It was noted that the concentrations of traitor guard and cultists were centred on units of Emperor's Children, and this pointed to an imminent major offensive in the south.

On the ground, General Wavell explained to his superiors that countering this new threat would be challenging. Operation Failsafe - the plan to abandon mainland Zadoc, had only been halted by the the timely arrival of the Adeptus Mechanicus to bolster the front, and even then the advance in the south had been limited. Wavell simply didn't have the troops to pre-empt the chaos assault, and all he could do was prepare for the oncoming onslaught.

Wind of the activity of the Emperor's Children reached the Ordo Hereticus, and from there the ears of the leader of the Carcharadons in the area. Relishing the opportunity to ruin the hated traitors' plans, the astartes chapter quickly drew up a plan of attack.

On 0802.014M42 the Carcharadons assaulted the chaos marine positions just to the east of the imperial front line. They targetted specific positions identified as command and control points by their own strike cruiser's surveys, and conducted devastating aerial assaults against the traitor astartes. Ancient war machines and martial prowess were no help to the Children, who could not stand against the uncontrolled blood lust unleashed by the loyalists marine chapter. In just a few hours of fighting the Emperor's Children had suffered heavy casualties, and lost critical equipment. In addition, the destruction of these key elite units caused a temporary lapse of command and control over the chaos forces, destroying the planned offensive against the Imperium on Zadoc for weeks.
