During the siege of Darius Alexander turned to a proposal to give him all of the land west of the Euphrates and to pay 10 thousand talents, if Alexander will return freedom to relatives of the king, marrying his daughter and to conclude a treaty of friendship and alliance. When Darius proposals were read staff, Parmenion allegedly said: "If I were Alexander, I would agree, and ended the war, avoiding dalneyshegoriska" what Alexander said: "If I were Parmenion, I would agree, but I - Alexander and respond differently ". Then he announced that he agreed to make peace, if he will lose the whole Persian Empire. From the point of view of common sense Parmenion was in many respects the rights. Meanwhile, Alexander has won a vast coastal areas of land west of the Euphrates; Antigonus, who commanded the troops in Asia Minor, has already given three battles enemies trying to cut the lines of communication. These lands would be enough to accommodate the excess of the Greek population and the creation of a single economic unit with the Balkans. And indeed Greece has not yet been completely pacified. After the battle of Issus, Alexander captured and kept in detention after heading to Darius, from Athens and Sparta and Athens had just entered military training for young people (ephebia). In addition, Pharnabazus gave Agis, king of Sparta, money, ships, and 8,000 Greek mercenaries from Tripoli to entice Crete to the Persians, and cut the sea lanes between Greece and Tyre. It was much more important than a gold crown, sent by the Board of the Hellenic League in honor of the victory at Issus. More important was the fact that Asian land west of the Euphrates could defend as demonstrated later Rome, the forces based in the Mediterranean as well as the belief that the future interests of Macedonia and Greece responds better to westward expansion against the peoples of Europe, the since some of them have already fought Alexander Molosser. But the all-conquering genius Alexander dictated to him a different answer. After defeating Darius resist him in the rear will be no one, and the eastern limits of the Persian Empire, he imagined, it is far from inhabited Asia borders. He was only 24 years old. Then, when the Persian Empire is conquered, he can send his army in the Western Mediterranean, but now he wanted to go east. His decision was one of the turning points in the history of civilization.
