Travels in the Central Parts of Indo-China (Siam), Cambodia, and Laos (Vol. 2 of 2): During the Years 1858, 1859, and 1860

In Short

This volume captures the final expeditions of French naturalist and explorer Henri Mouhot as he travels through the interior regions of Siam, Cambodia, and Laos. Mixing scientific observation with personal narrative, Mouhot documents imposing ruins like Angkor, encounters local sovereigns and remote tribes, maps untamed rivers, and catalogs hundreds of unseen species. His observations provided European readers with early detailed accounts of regional geography and culture. The book endures as a vivid historical travelogue that balances botanical precision with the perils of nineteenth-century exploration.

The Story

The narrative resumes as Mouhot travels through the heart of Cambodia, guided by a relentless passion for geographical discovery and natural history. Arriving at the formidable ruins of Angkor Thom and Bassette, he meticulously records their architectural details—describing stone gateways shaped like triumphal arches, elaborate bas-reliefs, carved dragons, and overgrown sandstone terraces. Astonished by the scale and artistic sophistication of these jungle-bound monuments, he speculates on the origin of their builders and notes how centuries of conflict between Cambodia and Siam have depopulated once-thriving provinces.

From the ancient stone monuments, Mouhot pushes northward into Siam and the rugged mountain regions of Laos. His journey is marked by arduous terrain and endless physical hazards. Rainstorms turn paths into quagmires, forcing his caravans of pack oxen and elephants to crawl through dense forests like the dreaded Dong Phya Phai. Navigating these habitats means enduring severe insect plagues—especially swarms of relentless mosquitoes—and facing tropical fevers that strike down members of his party. Along the way, he collects and catalogs rare insects, land shells, reptiles, and freshwater fish, while carefully plotting the courses of major tributaries flowing into the Mekong River.

Mouhot’s progress depends heavily on navigating regional politics. He halts at provincial capitals and small hamlets, negotiating with local mandarins, village chiefs, and monarchs for passage, guides, and fresh supplies. To secure goodwill, he distributes trade goods—ranging from European engravings and magnifying glasses to brass nails, soap, and brandy. While critical of the extortionate demands made by local officials, he forms warm relationships with Chinese traders, missionary priests, and Laotian guides who assist his movements across isolated borders.

After returning briefly to Bangkok to replenish his depleted funds and secure official passports, Mouhot embarks on a long, fateful trek deep into Western Laos. He reaches the remote kingdom of Luang Prabang in mid-1861, recording its courtly customs, daily religious chants, and surrounding landscape. However, the cumulative strain of extreme weather, physical exhaustion, and tropical disease takes its toll. The main narrative gives way to his final correspondence and postscript documents from colleagues and scientific societies, revealing that Mouhot succumbed to fever at the age of thirty-five. The volume concludes with tributes to his courage and the scientific value of the maps, journals, and specimens sent home.

How It Unfolds

The ruins of ancient empires Mouhot explores the grand stone remains of Angkor Thom, Bassette, and Banone, measuring doors, studying inscriptions, and marveling at the lost civilization that built them.

Crossing the King of Fire The expedition journeys through the dangerous Dong Phya Phai forest, enduring heavy rains, thick mud, and fatal fevers while Chinese merchants burn incense to ward off local spirits.

Surveying the Siamese interior Navigating towns like Korat and Leuye, Mouhot maps major rivers, inspects crude iron-smelting operations run by local villagers, and gathers rare botanical and zoological specimens.

Audience with regional rulers To secure safe passage toward Laos, Mouhot presents gifts—including spectacles, brandy, and political prints—to local kings and mandarins who control access to the interior routes.

The final push to Luang Prabang After a necessary retreat to Bangkok for supplies, Mouhot travels nearly seven hundred miles inland, reaching Luang Prabang to complete his mapping before succumbing to terminal illness.

The People

• Henri Mouhot: A dedicated French naturalist and traveler driven to map uncharted regions and collect unknown flora and fauna. He endures extreme fatigue, severe insect bites, and extortion, maintaining his scientific resolve until his death from fever.
• The King of Siam: A monarch who travels with a sprawling entourage of slaves and awkwardly uniform-clad soldiers. He grants audiences in Bangkok and Pechaburi, accepting European gifts while managing diplomatic ties with Western powers.
• The Second King of Laos: A regional ruler in Luang Prabang who receives Mouhot in audience. He accepts practical novelties like magnifying glasses, soap, and brandy in exchange for facilitating the traveler's passage.
• Father Silvestre: A missionary stationed at Battambong who corresponds with Mouhot. He later writes about regional uprisings, attacks on mission houses, and the arrival of French gunboats to restore order.

In Its Own Voice

"Thousands of these cruel insects suck our blood night and day. My body, face, and hands are covered with wounds and blisters."

During his survey near the Khao Deng mountains, Mouhot suffers under relentless mosquito attacks that drive him to pure exasperation.

"A hammer touching the walls would have disfigured them; he had only to level the ground, and to make staircases to aid the descent into the grottoes..."

Observing the natural royal cavern-temple at Pechaburi, Mouhot admires how the architect preserved the raw subterranean rock rather than altering it.

"I am literally pillaged by these petty mandarins and chiefs of villages, and have to give away guns, sabres, lead, powder, colours, pencils, and even my paper..."

While attempting to secure guides in the Laotian interior, Mouhot writes frustratedly of the endless demands made on his supplies by local authorities.

What It's Really About

Underneath the daily log of mileage, river widths, and specimen counts, the book explores the tension between nineteenth-century European scientific ambition and the harsh realities of wilderness travel. Mouhot approaches the land as a surveyor and naturalist, seeking order in unmapped rivers, forgotten architecture, and unclassified species. Yet his accounts constantly reveal how vulnerable a solitary traveler remains to local political authority, difficult terrain, and tropical disease. The text also reflects early European curiosity regarding lost Asian civilizations, contrasting the grandeur of historic monuments with the modest, war-torn villages surrounding them. Ultimately, it is a record of human endurance driven by an obsessive desire to expand geographic knowledge.

Why Read It Today

This travelogue appeals to readers who appreciate genuine historical exploration, nineteenth-century natural history, and colonial-era Asian history. Mouhot’s writing carries a direct, observational tone free of sensationalism, offering an authentic look at Southeast Asia just before deep European colonization altered its landscape.

Reading the book requires patience with nineteenth-century formatting, including embedded scientific lists, foreign place names, and the racial and cultural biases typical of a Victorian-era European observer. Its structural shift from a personal daily journal to posthumous letters and tributes reminds the reader of the real dangers the author faced. What remains with the reader is Mouhot’s unyielding curiosity—whether he is describing a rare land shell, observing an elephant caravan crossing a mountain pass, or writing field notes on his knees in a isolated forest hut.
