Journal of the Waterloo campaign, vol. 1 (of 2)
kept throughout the campaign of 1815
Cavalié Mercer (1783–1868)
This journal offers a rare, ground-level perspective on the Napoleonic Wars, capturing the visceral reality of 1815 through the eyes of a professional soldier. It strips away the pomp of history to reveal the grit, exhaustion, and sudden, chaotic violence of a campaign that shaped the modern world.
In Short
This book is a raw, evocative diary written by a British horse-artillery commander during the Waterloo campaign. Rather than providing a broad strategic overview, it chronicles the daily life, anxieties, and combat experiences of an officer leading his men from the initial arrival in Belgium to the aftermath of the decisive battle. Because it was written from rough daily notes soon after the events occurred, it retains an immediacy and vividness that standard military histories lack, preserving the sights, sounds, and moral ambiguity of the era for future generations.
The Story
The narrative begins with the quiet, often tedious experience of a military force occupying foreign territory. As the British army settles into Belgian villages, the author details the mundane challenges of billeting soldiers and horses in dilapidated farmsteads and ancient chateaus. He paints a portrait of a landscape caught between the beauty of its Gothic architecture and the tension of an impending conflict. Much of the early experience is marked by the peculiarities of local life, from the elaborate rituals of the Catholic Church to the eccentricities of the villagers who host his troops.
As the campaign progresses, the atmosphere shifts from the calm of the march to the urgency of mobilization. The author candidly admits to his own errors, such as misjudging the logistics of moving ammunition over muddy, broken roads, and describes the growing anxiety as rumors of Napoleon’s movements filter through the camps. The tension culminates in the maneuvers leading up to the Battle of Waterloo. The author provides a detailed, unflinching account of the fighting at Quatre Bras and the subsequent withdrawal, where his troop is tasked with covering the retreat of the army.
The focus then turns to the crucible of the battle itself. The account is intensely personal; the author describes the sensory overload of the cannonade, the terrifying precision of cavalry charges, and the sight of Napoleon himself during a reconnaissance. The narrative does not shy away from the horrific costs of the engagement. He chronicles the destruction of his own unit, noting the staggering number of horses killed and the physical and mental exhaustion of his men, who remain blackened by powder and blood long after the fighting ceases.
The conclusion is a sobering reflection on the aftermath. As the author wakes to a landscape still littered with the dead, he describes the relief of moving away from the field, yet he remains burdened by the memory of the ordeal. He captures the surreal quality of the transition from the "infernal uproar" of the battle back to the rhythms of rural life. The journal serves as both a testament to the endurance of his men and a stark rejection of romanticized war. He does not seek glory, but rather records the grim facts of their survival, leaving the reader with a profound sense of the weight that these events placed upon those who lived through them.

The People
The author, Cavalié Mercer, stands at the center of the narrative as a vigilant, observant professional who is acutely aware of the fragility of his command. He is both a soldier and an amateur artist, a combination that allows him to capture the picturesque beauty of the Belgian countryside alongside the grim mechanics of war. Throughout the journal, his primary motivation is the preservation of his men and the efficiency of his troop, yet he is never afraid to admit to his own tactical errors or his feelings of helplessness when confronting superior numbers or administrative failures.
Surrounding him are figures like the local Juge, a character who initially appears to be a nuisance but proves to be an unexpectedly loyal ally, and various fellow officers like Sir Augustus Frazer, whose shared meals and conversations provide a fleeting sense of normalcy before many of them fall in battle. These men appear as transient figures, defined by their camaraderie and the sudden, random nature of their deaths. Through these interactions, the author illustrates the contrast between the warmth of temporary friendships and the impersonal, destructive nature of the battlefield, ultimately depicting the human cost of the conflict through the loss of those he knew well.
In Its Own Voice
The Quai was silent and dark; the only light gleamed dimly through the wet from a miserable lamp over the door of a café, in which people were still moving; and the only sounds that broke the stillness of the quarter were the splashing of the rain and the clattering of our steel scabbards and horses’ feet.
The author describes the somber atmosphere of his arrival in a Belgian town during the early, uncertain days of the campaign.
My poor men, such at least as were untouched, fairly worn out, their clothes, faces, &c., blackened by the smoke and spattered over with mud and blood, had seated themselves on the trails of the carriages, or had thrown themselves on the wet and polluted soil, too fatigued to think of anything but gaining a little rest.
Following the intensity of the battle, the author captures the profound physical and emotional exhaustion of the survivors in his troop.
What It's Really About
At its core, the journal is an exploration of the disparity between the romanticized perception of war and the technical, messy reality of military life. The author examines the nature of duty, emphasizing that leadership is less about grand heroics and more about the tedious management of resources, the shoeing of horses, and the constant navigation of logistical failure. There is an implicit argument here that the "glory" of Waterloo was built upon the backs of men who were largely forgotten in the strategic reports of the day. The book asks what remains of a person after they have participated in such a monumental catastrophe, and how one reconciles the beautiful, tranquil world of the Belgian countryside with the blood-soaked reality of the battlefield.
Why Read It Today
Readers who appreciate firsthand historical accounts will find this book essential. It is not a dry military analysis; it is a vivid, sensory experience that transports the reader directly into the mud, the smoke, and the exhaustion of the 1815 campaign. You will feel the weight of the rain on the soldiers’ shoulders and the frustration of waiting at a crowded gate.
The prose is precise and elegant, reflecting the sensibilities of the nineteenth century, though modern readers should be prepared for the occasional technical detail regarding artillery or the period-specific attitudes of the author toward the local peasantry. It is a dense, thoughtful work that rewards patience. What stays with you long after finishing is not the outcome of the battle, but the quiet, haunting images of the aftermath—the sun rising over a field still scattered with the dead, and the soldiers’ desperate need to simply wash the blood and grime from their faces before moving on. It is a profoundly human document that reminds us that beneath every major historical event lies a multitude of personal, lived experiences that are often far more compelling than the dates and movements found in textbooks.
