conversion of a pastoral people into settled farmers and town-dwellers, wearing woven clothing and enjoying the benefits of an ordered life. The population had also expanded. It has been calculated by G. T. Griffith on the basis of recorded troop figures that Philip’s economic policy brought about an increase of over 25 per cent in the numbers of men available for the army between 334, when Alexander mobilized 27, 000 Macedonians for his Persian expedition and for service in Greece (with some 3000 men already in Asia and perhaps 20, 000 old and young for home defence), and 323, when the figures reached about 50, 000 (including a margin for casualties meanwhile sustained in Asia).
Philip’s army had won him control over Greece, but he could not afford to leave it idle. No sooner had he established peace there than he planned to invade Persia. The idea was not new. Ten years earlier the Athenian publicist Isocrates had addressed a speech to Philip urging this very course.
I am going to advise you to become the leader both of Greek unity and of the expedition against the barbarians; it is advantageous to employ persuasion with Greeks and a useful thing to use force against barbarians. That is more or less the essence of the whole matter (Isocrates, Philip, 10).
Isocrates continues a little later in the same speech:
What opinion do you imagine everyone will form of you if you try to destroy the whole Persian kingdom or, failing that, to annex as much territory as you can, and to seize Asia, as some are urging you, from Cilicia to Sinope, and if as well you found cities in this region and settle in them there those men who are now wandering around through lack of their everyday needs, and doing outrage to whomsoever they fall in with? (Isocrates, ibid., 120).
It is likely that Philip saw Asia as a source of wealth and new lands in which to settle the many exiles and dispossessed people who were at this time a general threat to both Greece and Macedonia, given that there were states with sufficient wealth to hire them as mercenaries. Whether the territorial limits suggested by Isocrates formed part of Philip’s original plan we cannot tell. Isocrates later admitted that his advice merely chimed in with Philip’s own inclinations, and perhaps what matters most is that such ideas were in the air. Philip, however, saw his enterprise in a much more obviously Macedonian context than Isocrates had envisaged. When in 336 Philip was assassinated, an advance force of 10, 000 men was already across the Hellespont. Thus on his accession Alexander found the Persian War half-begun but it had his wholehearted approval, for by it he hoped to win personal glory – and also to strengthen his position vis-à-vis the senior advisers whom Philip had left him (for he was only twenty). His first two years (336–4) were spent securing his northern frontiers in Thrace and Illyria and suppressing a revolt in Greece. Then in spring 334 he crossed over into Asia with a modest force of about 37, 000 men, of whom 5000 were cavalry. There were 12, 600 Greeks (7600 sent by the League and 5000 mercenaries), about 7000 tribal levies from the Balkans, nearly 2000 light-armed and cavalry scouts from Thrace and Paeonia and the remaining 15–16, 000 were Macedonians and Thessalians. Europe he left in the charge of his general Antipater with an army of 12, 000 infantry and 1500 cavalry – about as many Macedonians as he took with him (Diodorus, xviii, 17, 3 and 5). His finances were shaky and on arriving in Asia he planned to live off the country.
Alexander’s army was to prove especially effective because of its balanced combination of arms. A great burden lay on the light-armed Cretan and Macedonian archers, Thracians and Agrianian javelin-men. But the striking force was the cavalry and, should the cavalry-charge leave the issue still undecided, the infantry phalanx, 9000 strong, armed with 15–18 foot spears and shields, and the 3000 hypaspists of the royal battalions would deal the final blow. The army was accompanied by surveyors, engineers, architects, scientists, court officials and historians. From the start Alexander seems to have envisaged an operation with no clear limits.
After a romantic visit to Troy he won his first battle at the river Granicus near the Sea of Marmara, and as a gesture sent 300 suits of armour from the spoils as a dedication to Athena at Athens by ‘Alexander, son of Philip, and the Greeks (except the Spartans) from the barbarians who inhabit Asia’ (Arrian, Anabasis, i, 16, 7). His intention, underlined by the omission of all reference to the Macedonians, was clearly to emphasize the ‘panhellenic’ aspect of the campaign. At Dium in Macedonia on the other hand he set up brazen statues of twenty-five Macedonians who fell in the first encounter (Arrian, Anabasis, i, 16, 4). The victory gave access to western Asia Minor and by the spring of 333 Alexander was master of the western seaboard, most of Caria, Lycia and Pisidia, and could press ahead through Gordium (where tradition told of his loosing – or cutting – the famous Gordian knot, a feat which could only by performed by the man who was to rule Asia) to Ancyra and thence into Cilicia. In autumn 333 he encountered Darius himself at Issus (near Iskenderun) and by a second great victory laid open the route into Syria. There Tyre held out for seven months, but Alexander did not relax the siege, and meanwhile received peace proposals from Darius, whose family had fallen into his hands at Issus. Darius offered him a ransom of 10, 000 talents for his family, the cession of all lands west of the Euphrates and a marriage alliance (Arrian, Anabasis, ii, 25, 1) but Alexander’s ambitions had now clearly expanded and he rejected the offer. By the winter of 332 all Syria and Palestine was in his hands and he was in Egypt, where he founded a new city, Alexandria, before making a journey through the desert to consult the famous oracle of Amon at Siwah. His strategic object at this time seems to have been to seize the whole sea-coast and so protect his base in Greece and Macedonia from any possible naval attack. For he had already taken a bold step: he had ‘decided to disband his navy both from lack of money at the time and also seeing that his fleet was not capable of an action against the Persian navy’ (Arrian, Anabasis, i, 20, 1). Perhaps too he mistrusted the Greeks who manned it. In fact, the death of Darius’ admiral Memnon in 333 had deprived the Persian fleet of most of its bite, and on land a Persian counter-attack in Asia Minor in winter 333/2 had been defeated.
In the summer of 331 Alexander once again met Darius’ army, this time at Gaugamela beyond the Tigris, not far from Nineveh. It was the decisive battle of the war and again Alexander was victorious, pursuing the retreating forces for thirty-five miles and then quickly advancing to occupy Babylon. Seizing the royal treasures, which amounted to 50, 000 gold talents, he advanced further into Persia proper, where he took Persepolis and Pasargadae. The burning of Xerxes’ palace at Persepolis was perhaps intended as a symbolic end to the war of revenge, the panhellenic war; such at least is Arrian’s view (Anabasis, iii, 18, 11), though other writers explain the incident, less probably, as arising out of a drunken escapade, inspired by a courtesan. At any rate, ‘on reaching Ecbatana Alexander sent back to the sea the Thessalian cavalry and the rest of the allies, paying each the agreed pay in full and himself making a largess of 2000 talents’ (Arrian, Anabasis, iii, 19, 5). Henceforth Alexander was to be waging a personal war. Placing the treasure under the control of Harpalus and leaving Parmenion, one of Philip’s generals, to control communications, he now pressed on at high speed after Darius. But Darius had been deposed by a usurper, Bessus, and Alexander found him stabbed and dying near Shahrud. Nothing now stood in the way of his claim to be the Great King, and a dedication of arms and bulls’ skulls at Lindus, probably in 330, was accompanied by the record:
King Alexander having defeated Darius in battle and become lord of Asia sacrificed to Lindian Athena in accordance with a prophecy in the priesthood of Theogenes, son of Pistocrates (Timachidas, Fragmente der griechischen Historiker, 532, c. 38).
The wording shows that Alexander’s new pretensions were now conveyed to the Greeks at home.
Crossing the Elburz mountains the king now advanced into Hyrcania, which lay to the south of the Caspian Sea, and after a short westward diversion towards the region of Amol, he accepted the surrender of Darius’ Greek mercenaries. He then marched east through Aria and Drangiana where at Phradah he found an excuse to eliminate the now irksome Parmenion. Parmenion’s son, Philotas, the commander of the élite Companion cavalry, was here accused of plotting against Alexander’s life and having been found guilty by the Macedonians was executed. At once a secret messenger was dispatched to Media to ensure the assassination of his father:
possibly because. . . Parmenion was already a grave danger, if he survived when his own son had been put to death, being so highly thought
