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.
But to men who had been on the march for eight years, such arguments had little appeal. They had bathed in the Tigris and the Indus, the Nile and the Euphrates, the Oxus and the Jaxartes. Across desert, mountain, steppe and field they had trudged for over twenty-five thousand kilometres. Of victory, booty, glory and novelty they had had their fill. With respect and real affection, they listened to their leader, moved but unpersuaded.
Alexander withdrew to his tent like his hero Achilles. A three-day sulk made no greater impression on the men’s resolve, while a sacrifice for safe passage of the river produced only adverse omens. In the end Alexander had no choice but to announce a withdrawal. The banks of the Beas erupted with cheers of relief; many wept but all rejoiced. As Arrian noted, Alexander was vanquished only once – and that by his own men.
To round off his conquests, complete his explorations, and disguise his failure, Alexander opted to return by sailing down the Jhelum and the Indus to the ocean. Ships were readied and he sailed in late 326 BC. The voyage downriver took six months. Stern opposition came from numerous riverine peoples, some of whom have been tentatively identified, and from sizeable townships which clearly included well established brahman communities. Some of these townships no doubt occupied sites beneath which the Harappan cities had already lain, cocooned in alluvial oblivion, for 1500 years.
In an engagement with the ‘Malloi’ Alexander himself was seriously wounded. An arrow struck him in the chest and may have punctured his lung. He barely recovered. The wisdom of forgoing a contest with the Nandas’ multitudinous cohorts was amply demonstrated; so were the dangers of withdrawal. With few regrets, in September 325 BC the fleet sailed out of the Indus into the Arabian Sea. Meanwhile Alexander led the rest of his men west on what proved to be, for many, a death-march to Babylon along the desert coast of Gedrosia (Makran). There was still some talk of returning to India, of resuming the march with fresh troops, and of consummating the ultimate conquest. But other appetites proved Alexander’s undoing. Within two years he died from hepatoma following a massive banquet in Babylon.
With him from India had gone the wherewithal for a vastly enriched Western image of the land beyond the Indus. He had prised open a window on the East through which emissaries would pass, ideas would shine, and prying eyes would covet. With him too went all those Hellenised personae and places – Omphis, Aornos, Porus, the Malloi and countless others – never to be heard of again in India’s history. The ‘invasion’ had amounted to little more than a hasty intrusion, scuffing a corner of the carpet but neither baring its boards nor troubling its political furniture.
With Alexander there had also gone one ‘Calanus’, a figure worth remembering in that he seems to be the first Indian expatriate to whom a name and a date can confidently be given. One of a group of ascetics encamped near Taxila, Calanus had accepted Alexander’s invitation to join him in that city and subsequently accompanied him back to the west. There, in Persia shortly before his patron’s death, his own death would cause a sensation.
Calanus’ doctrinal persuasion is uncertain. As one of his companions at Taxila had put it, trying to explain one’s philosophy through a wall of interpreters was like ‘asking pure water to flow through mud’. In that Calanus and his friends went naked, a condition in which no Greek could be persuaded to join them, they may have been nigrantha or Jains. Jain nudity was dictated by that sect’s meticulous respect for life in all its forms. Clothes were taboo because the wearer might inadvertently crush any insect concealed in them; similarly death had to be so managed that only the dying would actually die. Jains bent on ending their life, therefore, usually starved themselves to death. Yet Calanus, a man of advanced years, chose to immolate himself on his own funeral pyre. Though an extraordinarily stoical sacrifice in Greek eyes, this was a decidedly careless move for one dedicated to avoiding casual insecticide. Evidently the Persian winter had induced a chill, if not pneumonia, and Calanus had decided it was better to die than be an encumbrance. No one, not even Alexander, could dissuade him from his purpose. He strode to his cremation at the head of an enormous procession and reclined upon the pyre with complete indifference. This composure he maintained even as the flames frazzled his flesh.
Visibly shaken by such an exhibition, the Greeks held a festival in his honour and drowned their sorrows in a Bacchanalian debauch. Calanus, though he had made no converts, had won many friends. He also left a profound impression well worthy of India’s first cultural emissary. ‘Gymnosophists’, or ‘naked philosophers’, henceforth became stock figures in the Western image of India. As ‘Pythagoreans’, they were also identified with Greek traditions of abstinence and the conjectures of Pythagoras about rebirth and the transmigration of the soul. Lucian, Cicero and Ambrose of Milan all wrote of Calanus and his naked companions. Much later, as the epitome of ascetic puritanism, India’s gymnosophists would be
