The Persian success in the battle led to the creation of Persia's first empire and began Cyrus' decade long conquest of almost all of the known world.
[10] Based on scant sources the battle (which was in Hyrba) is believed to have taken place at least half a year after the revolt had already begun,[11] probably in the beginning of winter in 552 BC.
[15] This matches the account of Nicolaus in which he says that Cambyses I had already assembled many troops well before the battle had started, and that he later despatched a small number to Cyrus's aid.
[16] Cyrus sent a message to his father saying "... send at once 1000 cavalry and 5000 foot-soldiers to the city of Hyrba which lay on the way, and to arm the rest of the Persians as quickly as possible in such a way that it should seem to be done by command of the king.

In the night he and Oebares took horse, just as they were, hastened to Hyrba, armed the inhabitants, and drew out those whom Atradates had sent in order for battle.
The remainder escaped, and brought the news to Astyages.Concerning the troops types, it is unknown whether or not the Persian infantry engaged in the battle.
