By this time, casualties on both sides were so great that "the entire plain was covered with the dead; bodies were piled up in huge mounds, and the dromedaries especially fell in heaps". At this point, Macrinus, with his army on the verge of breaking, sent another embassy to Artabanus, informing him of Caracalla's demise and offering a substantial compensation. The Parthian army had also suffered large casualties, and moreover, since it was not a professional but a feudal militia force, it had started to become restive at the prolonged campaign. Thus Artabanus agreed to a peace, after receiving 200 million sesterces.
