Kalidar War - To Break the Stalemate: Recently freed for service by the successful conclusion of the Indranis Campaign, a sizeable Battlegroup of Astra Militarum regiments -- the Dentares Wargroup -- was rerouted to Kalidar following the Ork assault. Having suffered heavy casualties against the Aeldari, the Wargroup was expected to make a stop at the lunar colonies of Paragon from which many of its regiments had been raised.To further strengthen the Imperial expeditionary force, two new regiments were raised, the 42nd Paragonian Armoured and the 63rd Paragonian Mechanised Infantry Regiments. While both regiments were made up of Paragonian troops, their officers were drawn from regiments depleted by the Dentares Suppression. It is a testimony to the organisational skills of the Departmento Munitorum and the Paragonian authorities under Planetary Commander Gondannick Lo Materiak that the raising of these two regiments did not delay the reinforcement more than a solar week.Officially renamed Battlegroup Kalidar, the Battlegroup embarked for its scheduled 4 solar month journey to Kalidar. However, severe turbulence in the Warp-turbulence delayed its transit, so that by the time the Imperial reinforcements reached the beleaguered world, 2 Terran years had passed.Battlegroup Kalidar was a motley collection of hardened veterans and green troops, which despite the harsh training provided by Training Sergeants drawn from the Cadian Shock Troops had yet to see their first battle. While most of the battlegroup's regiments were drawn from Paragon, its command rested with Captain-General Iskhandrian of Atraxia, a seasoned Astra Militarum general who had commanded the Dentares Suppression. The Battlegroup was further complemented by the addition of two regiments of Savlar Chem-Dogs, who were also veterans of the Dentares Suppression.By 397.M41, when Battlegroup Kalidar finally reached its destination, the situation on the ground had changed. The Orks had tried to break through the subterranean transit network. But the valiant efforts of the local military forces had blocked the Orks' progress, forcing the Greenskins to move their troops above ground where Kalidar's fierce climate could thin their numbers and slow their advance.Fortunately for Kalidar's defenders, a small detachment of Space Marines from the Black Templars Chapter had also heard the distress signal and responded. The Space Marines' involvement helped to stem the tide of Greenskins, ensuring that no other hive city fell to their assault. However the Orks grew bolder and began to roam far and wide from Hive Kimeradon, besieging several key mining facilities and threatening Hive Modulus.Fully aware of the difficult conditions his troops would face once on the Desert World's surface, Captain-General Iskhandrian planned for a quick war. The army group would land as close as possible to the enemy, in Hive Modulus, and clear the surrounding parts of the Kalidarian desert before pressing straight for Hive Kimeradon where Imperial intelligence had located the leader of the WAAAGH!, Warlord Gratzdakka.From the start, the prosecution of the Kalidar War would heavily rely on the quick progress of the battlegroup's armour and mechanised infantry regiments, especially since these formations could be supported by no less than two super-heavy tank companies, the Atraxian 18th and the Paragonian 7th, both of which were at full strength.
