Although Indian troops still served in the Achaemenid forces, it seems that Gandhara and ‘India’ had probably slipped from direct Achaemenid rule some time in the mid-fourth century BC. For Alexander it was enough that once upon a time these provinces had indeed been Persian; to excel Darius and Xerxes, he must needs take them. First, though, another long detour was necessary, this time along his northern flank. In 329–8 he pushed north-east into Arachosia (Afghanistan) and then crossed in succession the snows of the Hindu Kush, the swirling Oxus river and the parched scrubland of Sogdia (Uzbekistan). He then laid claim to the Achaemenids’ central Asian frontier on the distant Jaxartes (Syr) beyond Samarkand. It was not till late 327 BC that, returned to the vicinity of Kabul, he was ready with a force of fifty thousand to cross India’s north-west frontier.
Determined now to upstage not only the empires of Darius and Xerxes but also the mythical conquests of Heracles and Dionysos, Alexander seems increasingly to have seen his progress in terms of a Grail-like quest for the supposedly unattainable. He sought the ‘ocean’, the ultimate limit of terrestrial empire. Through knowledge of this great ‘beyond’, he aspired to a kind of enlightenment which, although very different from that of the Buddha, would become a cliché of Western exploration. More crudely, he hankered after sheer bloody immortality. ‘His motives need a little imagination,’ writes the best of his biographers, who then quotes one of Alexander’s companions: ‘The truth was that Alexander was always straining after more.’10
More was precisely what India offered. Like a tidal wave, news of Alexander’s prowess had swept ahead of him, flattening resistance and sucking him forward. Indian defectors from the Achaemenid forces primed his interest and paved the way; local malcontents promised support and provided elephants; judicious potentates sought his friendship. Principal amongst the latter was a king known to the Greeks as ‘Omphis’ or ‘Taxiles’. As the latter name implied, he was the ruler of Taxila, reportedly the largest city between the Indus and the Jhelum; and from a chance mention in an appendix to Panini’s grammar he has since been identified as Ambhi, an otherwise enigmatic figure in Indian tradition.
‘The first recorded instance of an Indian king proving a traitor to his country’11 seems an over-harsh judgement on the ambiguous Ambhi of Taxila. Alexander had divided his forces so that half marched largely unopposed down the Kabul river and across the Khyber Pass, while he himself led the remainder by a northerly route through the wintry hills to Swat. There, up among the pine forests of the supposedly impregnable hill fort of Aornos (Pir-i-Sar), he inflicted one of several vicious and salutary defeats on the mountain tribes. By the spring of 326 BC, when back in the plains he crossed the Indus to join up with the rest of his forces, the Macedonian’s reputation stood high.
A city built on trade and scholarship with little in the way of natural defences stood no chance. Taxila had survived the Achaemenids, indeed was a part-Achaemenid city. It could manage the Greeks in the same way. When Alexander descended to the Indus he found thousands of cattle and sheep, as well as elephants and silver, awaiting him. Ambhi, with nought to gain by resistance except the annihilation of his illustrious city and the applause of a very remote posterity, was playing safe. Alexander confirmed him as his satrap and generously repaid his liberality.
At the time Taxilan territory extended modestly from the Indus to the Jhelum. Beyond, occupying the next sliver of the Panjab between the Jhelum and the Chenab, the kingdom of ‘Porus’ lay across the invaders’ line of march. In Greek as in Indian tradition, Porus is all that Ambhi is not. A giant of a man, proud, fearless and majestic, he may have owed his name to Paurava descent, the Pauravas being only slightly less distinguished than the Bharatas in the pecking order of Vedic clans. Alexander had summoned him, along with other local rulers, to meet him and render tribute. Porus welcomed a meeting, adding casually that an appropriate venue would be the field of battle.
As good as his word, and despite the fact that the monsoon had already broken, Porus massed his forces on the banks of the Jhelum. Normally the monsoon brought all campaigning in India to an end. Indian troops were ill-equipped to fight in the rain, and Porus probably trusted to the flooding Jhelum to halt the enemy. But Alexander, well used to river crossings, organised boats, duped the enemy as to his crossing place, and between torrential downpours gained the further bank. The battle that followed was anything but a formality. Porus’ chariots slithered uncontrollably in the mud and his archers could find no purchase for their massive bows, one end of which had to be planted in the ground. Yet the Indian forces, though outnumbered as more of the enemy crossed the river, fought valiantly. Abristle with spearsmen, the elephant corps trundled across the battlefield like towering bastions on the move. Their repeated charges drove all before them, the Greeks merely peppering them with missiles as they reformed. But Alexander now knew enough of elephants to bide his time. His tactical skills were unmatched, and his cavalry easily outmanoeuvred their rivals. As the battle wore on, the Indians found themselves penned into an ever smaller circumference. Enraged elephants now trampled friend and foe alike. Exhausted, ‘they then fell back like ships backing water, and merely kept trumpeting as they retreated with their face to the enemy’. With shields linked, the Macedonian phalanx then pressed in for the kill. ‘Upon this, all turned to flight wherever a gap could be found in the cordon of Alexander’s cavalry,’ according to the account compiled by Arrian.
Porus, wounded but still conspicuously fighting from the largest of the elephants, was captured. ‘How did he expect to be treated?’ asked Alexander. ‘As befits a king,’ he famously replied. To the Greeks it sounded, under the circumstances, like an extraordinarily noble and fearless request. Alexander responded magnanimously, reinstating him as king and subsequently augmenting his territories. But Porus’ words could as well have been those of Lord Krishna, whose advice to Arjuna in the Mahabharata made much the same point. Each must live according to his dharma; it was the dharma of a ksatriya to fight and to embrace the consequences. Probably Porus was not boldly appealing to Alexander’s clemency, nor presuming on some brotherhood of sovereignty; he was simply stating his dharma.
After exceptionally elaborate celebrations, the Macedonians moved on, continuing east and south across the grain of the Panjab river system. The rains ended and the land blossomed. They crossed the Chenab, then the Ravi. Countless ‘cities’ capitulated, others, some evidently republican gana-sanghas, offered a short-lived resistance. Even to Alexander it was becoming apparent that ‘there was no end to the war as long as an enemy remained to be encountered’. Rumours of the vast forces commanded by the Nandas of Magadha (the ‘Gangaridae’ and ‘Prasii’ to the Greeks) now began to infiltrate the ranks. ‘This information only whetted Alexander’s eagerness to advance further,’ says Arrian. The Ganga, mightier even than the Indus, must surely carry them to the ocean at the end of the world. Its plain was reported as exceedingly fertile, its peoples excellent farmers as well as doughty fighters, and its governments civilised and well organised. Alexander sniffed the prospect of an even more glorious dominion.
But his men were unimpressed. They crossed what is now the frontier between Pakistan and India somewhere in the vicinity of Lahore. Then, near Amritsar, they reached the Beas, fourth of the Panj-ab, the ‘five rivers’. In this weird and interminable land where the clothes were all white and the complexions all black, it was as good a place as any for a showdown with their commander.
Alexander sensed the mood of mutiny. In a lengthy appeal to his commanders he invoked their past loyalty and stressed the consequences of retreat. Extricating themselves would be difficult. Were the tide of conquests now to ebb, they would find the sands sucked from under their feet. New friends would review their allegiance and old enemies would take their chance. Trumpeting an empty defiance, the Greeks would find themselves backing away amidst a shower of missiles just like Porus’ exhausted elephants.
