Clearchus however was so confident that all would go well, and pressed his opinion with such persistence, that after a long discussion it was at last decided to send five generals and twenty captains to take part in the conference. Clearchus was of course one of the five generals, so also was Menon. They were accompanied by two hundred soldiers who wished to buy provisions in the Barbarian camp, but all were unarmed, for it was to be a friendly meeting. Some hours passed by, and the Hellenes did not return. Those who were left behind began to look out anxiously for their comrades, but they could see nothing but a number of Persian horsemen galloping about separately in all directions upon the heath, which lay between the two camps. They did not understand what this could mean, but soon the horrible explanation was brought to them by a badly-wounded Hellene, who made his way back to the camp as fast as he was able, and told them what had happened. On reaching the tent of Tissaphernes, the five generals had been invited to go within; the captains were left standing at the door. Presently a blood-red flag was hoisted above the tent, and at this signal, the Barbarians fell upon the captains and the two hundred soldiers who were all unarmed, and massacred them. Those who attempted to flee were cut down by horsemen sent in pursuit of them, and killed upon the heath. Of the fate of the generals who had gone within the tent, the wounded man knew nothing. On hearing this terrible news, the Hellenes rushed to seize their arms, for they naturally expected an immediate attack. This did not however take place, but Ariæus, with some other nobles, and about three hundred Persian cavalry, rode towards the camp, and demanded to speak with one of the generals. When he was within hearing, Ariæus cried out, ‘Clearchus was a traitor, he had broken the oath, and has been punished. To you I bring an order from the Great King to deliver up your arms, for they belonged to Cyrus, who was his slave.’ Every one in the Persian empire was considered a slave, except the King himself. But one of the generals answered with spirit befitting the occasion. ‘Thou miserable Ariæus,’ he cried, ‘and you others who were the friends of Cyrus, you are the most wicked of men, you who formerly swore that our friends should be your friends, and our enemies your enemies, and have now entered into a covenant with the godless Tissaphernes to destroy us.’ To this the Persians could make no reply, and they turned back to their own camp.
