Soon, reinforcements from both sides arrived. It became clear to the Imperial forces the futility of fighting over a destroyed planet but by then there was no turning back. Although it could not be guessed at the time, the Chaos legion were motivated beyond mere destruction. Since the poisoned environment made it impossible for infantry to operate outside of protective shelter, the only available option of battle was that of armored tank warfare. The largest tank battle in human history erupted on the surface of Tallarn.{{cite this}}
Eventually, it was revealed by the work of Alpha Legion spies, including their operative Jalen, that Perturabo invaded Tallarn in search of the "Black Oculus" (aka the [[[[Cursus of Alganar]]), a portal that would allow the Iron Warriors to make a pact with demons and gain power. The Alpha Legion freed Horus's emissary, Argonis, in order to force Perturabo to stop.{{Fn|5}} By the end of it, the Iron Warriors were forced to withdraw by command of Horus, and the wreckage of over a million tanks littered the sands.{{cite this}}
Approximately twenty years after this, the official [[Tallarn Desert Raiders]] military force was formed. These regiments specialised in desert fighting, and were highly adept at ambushing enemy forces in the desert. The Tallarn Desert Raiders continued their attack on various worlds which had turned to Chaos until sometime around the 30th Millennium, when they were recalled.{{cite this}}
