      ‘Each bend of the Mekong as added to my map seemed an important geographical discovery. Nothing could distract me from this abiding concern. It came to possess me like a monomania. I was mad about the Mekong …’

      FRANCIS GARNIER

      IN EARLY JUNE the Mekong in its remote middle reaches is at its lowest. At that time of year, sixteen hundred kilometres to the north-west on the uplands of eastern Tibet, the river’s headwaters may be rippling with the first snow-melt, while the same distance to the south, the monsoon may already be pummelling the paddy fields of the Delta. But at its hill-pinched waist on the Lao-Burmese border the river has scarcely begun to rise. Here, the dry season still holds its fiery breath and the odd shower is no more than a lick of the tongue on parched lips. Behind the hills desultory thunder brings no relief. Beetles and cicadas fall silent in the heat; birds seem reluctant to fly. A smoke haze hangs motionless in the treetops, clogging the nostrils with the ash from slash-and-burn. Drained of all glow, the sun sets ingloriously, tracking behind a pall of parched fog to a mid-afternoon extinction. The thermometer stays stuck at thirty-something degrees.

      Only the river is refreshingly animated. Darting through fifty-metre narrows, it bellies into pools a kilometre wide and then squirms, like a sleek and well-fed snake, down a barren trough isolated from the tousled shade of its banks by humped sandbars and a wilderness of spectacular upthrusts of black bedrock. Where the rock ventures into its path, the river hisses a caution and recoils in a tangle of eddies, welling up, flicking at the sunlight and glancing aside to nose out other options before slithering prodigiously over the obstruction in a cascade of watery colours.

      Midway between Thailand and Chinese Yunnan, a succession of such encounters comprises the Tang-ho rapids. They extend, with intermissions, for perhaps 150 kilometres and confront the navigator with an awesome prospect of boiling whirlpools and spuming cataracts. In June 1867 they were the final straw for the Mekong Exploration Commission. After a year of canoeing up Asia’s most capricious river, the six Frenchmen who had undertaken its exploration conceded defeat. From here on they would take to the steep banks, then to the hills and the forests, plotting the river where possible but increasingly deflected from its course by obstructive princelings and their own debilitated condition.

      Their proximity to China alone kept them going. Deep in the forest gloom they would stumble on a paved trail and then a humpbacked bridge built of cut stone and once inset with ceramic tiles. Evidently the civilising light of the Celestial Empire had once penetrated these dark recesses. A mandarin’s robes and the staccato sound of spoken Chinese sent the Frenchmen into raptures. In China their credentials would be acknowledged and their credit was good. After months of floundering amid malarial jungle, terrorised by tigers, devoured by leeches, often feverish and increasingly destitute, their salvation seemed nigh. They dreamed of wearing shoes again and sleeping in sheets, of tableware and postal facilities and the privacy of stone walls and stout doors. They were not to know that forsaking the river was the prelude to catastrophe, or that the controversies, no less than the crises, were yet to come.

      Sensing only that the Mekong was about to elude them, Francis Garnier, the expedition’s restless surveyor, set off alone from the Tang-ho rapids on a last day’s excursion upriver. With a compass in his hand and a cold chicken in his haversack, he picked his way past the rapids, and as the sun slanted over the trees on the hilltops, became overwhelmed by an acute sense of wonder. The great river and the boundless forest were utterly deserted. He felt like a trespasser in paradise. He shouted to reassure himself but quickly resented the sound. His shadow, marching across the sandbanks beside him, was no less intrusive: it seemed, as Garnier put it, ‘to violate the virginity of a natural world that until now had escaped the profanity of man’.

      Behind an outcrop of rock he surprised a young stag drinking from the river. Though only ten paces away, it stood its ground, and when he stopped to reach instinctively for his rifle, the stag actually moved towards him. ‘It came to me like a memory of Eden,’ he would write. Both thrilled and intimidated, he had no regrets about being unarmed, yet still could not resist making a grab for its antlers. The stag bolted and Garnier cursed his own impatience. It should have been like a fairy story, he thought, or one of La Fontaine’s fables. If only, instead of grabbing at it, he had engaged it in polite conversation.

      After a hard scramble through the tangled forest to circumvent a portal of rock, he rejoined the river and, now sweating profusely, went for a swim. He was barely out of his depth when two elephants broke cover. One turned back; the other, a big dark tusker, waded into the water beside him. Garnier backed into midstream and prepared to take flight by launching himself into the main current. ‘The proboscidean’ fixed an eye on him and occasionally waved its trunk in his direction. But it did not approach. It seemed content just to wallow and shower itself with river-water. Naked and defenceless, Garnier cautiously floated into the bank and, grabbing his clothes, fled across the sands and into the forest. The elephant paid no attention. Later, on glancing back, Garnier could still see the spray from the fountain of its trunk raining down in a prism of sunlight.

      Lunch was taken in the shade, then it was time to turn back. In the heat of the day the silence was more absolute than ever. Garnier longed to erase his own tracks in the sand; they too seemed to sully surroundings of such heart-rending beauty. Yet that night, back in camp when he told of his adventures, a colleague’s suggestion that they revisit this huntsman’s ‘Eldorado’ with shotguns and rifles met with no objection. For repaying nature’s ‘pacific and almost friendly’ reception with bullets Garnier felt a mild pang of remorse but said nothing. Bloodlust prevailed. Evidently virgin lands meant fair game – and that included the river itself.
