It may seem strange that one satrap should have been able to wage war against another, whilst all the time both continued to be subjects of the Great King. But in point of fact, such rivalries between neighbouring satraps were rather encouraged than otherwise by the Great Kings, who lived in constant fear lest one or other of the great lords should take it into his head to make himself an independent sovereign, and consequently felt more secure when they were occupied in quarrelling among themselves. In this case moreover, the royal revenue suffered no loss through the revolt of the Ionian cities, for Cyrus took care to forward the tribute which they were required to send to Susa, just as regularly as it had before been sent by Tissaphernes.
Other opportunities also offered themselves to Cyrus for increasing the number of Hellene soldiers in his pay. About this time he received a visit from a Spartan named Clearchus, whose acquaintance he had made during the Peloponnesian war, and of whose ability as a military commander he had the highest opinion. Clearchus had come to him with a request on behalf of the cities of the Hellespont, who were at war with their barbarous neighbours, the Thracians, and could not hold their own against them without help. He wished to aid his countrymen by raising an army for their defence, and asked Cyrus to grant him for this purpose a sum of 10,000 darics.[8] The request was a large one, but it was at once granted by Cyrus.

A GOLD DARIC.
Shortly afterwards there came to him a Hellene from Thessaly, with a similar request. In his country, the party of which he was leader found itself hard pushed by the opposing faction, and he also desired to raise an army by means of which he and his friends might again have the upper hand. He asked Cyrus to let him have as much money as would enable him to hire 2,000 men for three months. ‘I will give you gold enough,’ said Cyrus, ‘to hire 4,000 men for six months, on condition that you prolong the quarrel with your enemies until I send for you.’
Other requests of a similar kind were also granted by Cyrus, always with an intimation that he might require the troops later on for his own service. And thus he secretly collected a force of Hellenes which he kept employed in other undertakings, but ready to come to him when he should want them.
Meanwhile he was careful not to neglect any means of improving the Barbarian soldiers of his provinces, and this could be done openly, for it was part of his duty as satrap to practise the troops in all kinds of military exercises calculated to increase their efficiency.
All this time the Great King was constantly sending spies to Sardis to find out what his brother was doing, but on their return the spies invariably reported that they had seen nothing that could be regarded as suspicious. The fact was that Cyrus knew so well how to make himself agreeable to the spies, that although they reached Sardis as the friends of the King, they always became, before leaving it, the friends of Cyrus.
Every step that he took was weighed by Cyrus with the utmost caution; every difficulty that was likely to present itself on the road to Susa was considered carefully and deliberately, in order to ascertain the best means of overcoming it. No feeling of impatience was allowed to urge him on to any rash or premature action.
