Cyropaedia

Now the Chaldaeans carried each a wicker shield and two spears, and they were said to be the most warlike of the peoples in that region. They also serve for hire when any one wants them, for they are fond of war and poor of purse; for their country is mountainous and only a small part of it is productive.

But when Cyrus and his men were getting[*](The battle) nearer to the heights, Tigranes, who was marching with Cyrus, said: Do you know, Cyrus, that we ourselves shall have to do the fighting, and in a very few moments? For the Armenians, I am sure, will never sustain the enemy’s attack. Cyrus answered that he knew that and gave the command to the Persians to make ready, as it would be necessary in a moment to give chase, as soon as the Armenians by pretending flight should decoy the enemy into close quarters.

So the Armenians led on. And when they came near, the Chaldaeans already there raised the battle cry, according to their custom, and charged upon them. And the Armenians, according to their custom, failed to sustain the charge.
