The Setting: Paris Under Prussian Guns

In the autumn of 1870, Paris found itself encircled by the disciplined armies of Prussia and its German allies. The Franco-Prussian War, ignited by diplomatic miscalculations and national pride, had reached its climax as the French capital endured a siege that would test its defenses, its spirit, and its very soul. The city, long celebrated as the cultural and political heart of Europe, now faced an existential threat from without and growing unrest from within. Under the leadership of General Louis Jules Trochu, the provisional Government of National Defense vowed to resist, yet the reality of their situation grew grimmer with each passing day. The Prussians, commanded by the methodical Helmuth von Moltke, showed no intention of storming the formidable fortifications but instead settled into a strategy of starvation and attrition, knowing that time was their greatest ally.

The mood within the walls oscillated between defiant optimism and creeping dread. Early hopes of a swift relief from provincial armies faded as weeks turned into months. Resources dwindled, morale wavered, and the harsh realities of siege life set in. Civilians and soldiers alike endured shortages of food, fuel, and hope, while the distant thunder of artillery served as a constant reminder of the enemy’s presence. Into this fraught atmosphere stepped observers like Juliette Lambert, also known as Madame Edmond Adam, whose firsthand accounts provide a vivid window into the daily struggles and occasional flashes of drama that characterized the siege.

A Glimpse of the Front: Madame Adam’s Visit

On October 7, 1870, Juliette Lambert ventured to the Fort of Montrouge to experience life on the front lines. Accompanied by the fort’s commandant, she witnessed a moment that encapsulated the bizarre blend of chivalry and brutality that marked the conflict. Through his telescope, the commandant spotted a Prussian officer seated nonchalantly in an armchair on the balcony of one of the finest houses in the village of L’Hay, some two miles distant. The officer, equipped with his own spyglass, was calmly observing the French positions—an act of audacity that the commandant found intolerable. With a terse order to “clear the balcony,” a cannon was fired. The shot struck true, obliterating the house, the balcony, the armchair, and the officer in a single, devastating blast. Lambert recorded her triumphant cheer, noting that it had been “a fine day.”

This incident, though perhaps embellished in the retelling, illustrates the peculiar nature of the siege during this period. Major engagements were rare; instead, the conflict consisted of sniping, skirmishes, artillery duels, and countless minor irritations. After the Battle of Châtillon, which had dashed French hopes of breaking the encirclement, the fighting settled into a tense stalemate. Elihu Washburne, the American minister to Paris, likened the post-Châtillon atmosphere to that of Washington after the First Battle of Bull Run: a scene of confusion and unrealized potential. He noted that had the Prussians understood the disarray within the city, they might have pressed their advantage. Yet, by October, the defenses had been strengthened to such an extent that a direct assault seemed unwise, if not impossible. The Prussians opted for patience, content to let hunger and despair do their work.

The Human Toll: Weather, Worry, and Waiting

As October wore on, the weather turned foul, replacing the oppressive heat of September with damp chill and lengthening nights. The approach of winter cast a pall over the city, exacerbating the hardships faced by soldiers and civilians alike. Makeshift barracks, poorly insulated and ventilated, offered little protection from the cold. There were reports of National Guardsmen freezing to death on duty, such as the tragic case on the Rue de Clichy. Even among the regular army and mobile guards, morale suffered as the endless inactivity took its psychological toll.

Officers, in particular, felt the strain of prolonged inaction. The anxious energy that had once been the province of radicals like Gustave Flourens and the Belleville district now spread throughout the command structure. A young English tutor named Charlie Carter, employed by the family of General Ducrot, captured the prevailing mood in a letter to his sister Fanny. He lamented the lack of progress, the endless stream of false reports designed to manipulate public sentiment, and the frustrating inertia that gripped the city. “The Prussians have been here for over a month, and nothing has been done,” he wrote. “Only false reports keep coming in, to encourage or to console, always adjusting to the times.” He questioned the efficacy of constant appeals to provincial resistance, noting that if more tangible results did not soon materialize, such efforts would prove futile.

Given the French temperament—proud, impulsive, and prone to dramatic gestures—it seemed inevitable that the tension would eventually boil over. That moment arrived on October 27, 1870, in the unlikely setting of the small village of Le Bourget.

The Spark: Le Bourget and the Ambition of General de Bellemare

Le Bourget, located less than four miles northeast of Paris’s walls, was an isolated village of no obvious strategic importance. Today, it is absorbed into the urban sprawl of greater Paris, and the surrounding plains host a major airport, but in 1870, it was merely one nondescript position among many in the contested no-man’s-land between the lines. Yet, like countless insignificant locales that would gain notoriety in later wars, Le Bourget became a focal point for military ambition and misadventure.

After the encirclement of Paris, the Prussians established an outpost in Le Bourget, but it was a precarious position. The village was overlooked by two powerful forts—Fort de l’Est and Fort d’Aubervilliers—and lay within range of the fortified town of Saint-Denis, which housed the relics of French kings and was strongly garrisoned. At the same time, the gradually rising ground to the north was under Prussian control, making the village vulnerable to artillery fire from the heights. Despite these drawbacks, Le Bourget exerted a magnetic pull on the French commander at Saint-Denis, Brigadier General Carey de Bellemare, an ambitious officer eager to make his mark.

Without consulting his superiors, de Bellemare took matters into his own hands. On the night of October 27, he dispatched some 250 Francs-tireurs—irregular light infantry—to attack the village. The Prussian garrison, a company of Guardsmen, was taken completely by surprise. By the following morning, the French flag flew over Le Bourget. Emboldened by this success, de Bellemare reinforced the position with two additional battalions, confident that he had secured a significant victory. On October 29, he left his post and traveled to Paris to personally inform General Trochu of his triumph.

The Reckoning: Trochu’s Fury and the Prussian Response

De Bellemare’s arrival at headquarters was met with consternation rather than congratulations. According to Trochu’s own account, the general was elated and immediately requested promotion to the rank of divisional general. Trochu, however, saw the capture of Le Bourget as a pointless and costly diversion. He considered the village indefensible and believed that de Bellemare’s unilateral action would needlessly lengthen the list of casualties. He was further astonished that a commanding officer would abandon his post at such a critical moment.

Even as de Bellemare stood in Trochu’s office, a telegram arrived reporting that the Prussians had launched a counterattack against Le Bourget. “That is where you should be!” Trochu exclaimed, sending the general back to the front. Yet de Bellemare returned that afternoon, dismissing the Prussian assault as a false alarm and reiterating his demand for promotion. This only deepened Trochu’s frustration and foreshadowed the disaster to come.

The Battle for Le Bourget: Valor and Vanity

The Prussian high command, under Crown Prince Frederick William, could not tolerate the loss of even a minor position like Le Bourget. Determined to retake the village, they assembled substantial forces for a coordinated assault. The fighting that ensued was some of the fiercest of the entire siege, characterized by close-quarters combat in the village streets and houses. French defenders, though outnumbered and outgunned, fought with tenacity, inspired by the belief that they were striking a blow for national honor.

For three days, the battle raged. The Prussians brought overwhelming artillery to bear, systematically reducing the village to rubble. French reinforcements struggled to hold the line, but without adequate support from the main defenses of Paris, their efforts were in vain. By October 30, Le Bourget was back in Prussian hands, and the French had suffered heavy casualties for no strategic gain. The episode exposed the disorganization and poor coordination that plagued the French command structure, as well as the reckless ambition of officers like de Bellemare.

Cultural and Social Impacts: The Mood in Paris

The loss of Le Bourget sent shockwaves through Paris. Initially hailed as a victory, the capture of the village had briefly lifted spirits and fueled hopes that the tide might be turning. Its rapid recapture by the Prussians dashed those hopes, replacing optimism with bitterness and disillusionment. The press, which had earlier celebrated de Bellemare’s initiative, now turned critical, questioning the competence of military leadership and the wisdom of offensive actions.

Socially, the failure at Le Bourget exacerbated existing tensions within the city. Radical elements, already distrustful of the conservative Government of National Defense, pointed to the debacle as evidence of incompetence or even treachery. Working-class neighborhoods, which had borne the brunt of conscription and hardship, grew increasingly restless. The siege, now entering its most difficult phase, began to fray the social fabric of Paris, setting the stage for the political upheavals that would follow the war.

Legacy and Modern Relevance: Lessons from Le Bourget

The story of Le Bourget is more than a minor episode in the Siege of Paris; it is a microcosm of the broader conflict and its consequences. It highlights the dangers of uncontrolled initiative in military operations, the importance of coordination and communication, and the tragic human cost of vanity and misjudgment. In the grand narrative of the Franco-Prussian War, Le Bourget serves as a cautionary tale about the perils of underestimating one’s enemy and overestimating one’s own capabilities.

Moreover, the events at Le Bourget had lasting implications for French military doctrine and political life. The defeat contributed to the growing disillusionment with the imperial and provisional governments, fueling the rise of the Paris Commune in 1871. It also influenced later military thinkers, who studied the siege for lessons on urban warfare, logistics, and the psychological dimensions of prolonged conflict.

Today, Le Bourget is remembered not only for its role in the siege but also as a symbol of resilience and folly. The village’s transformation from a battlefield to a hub of modern aviation reflects the enduring capacity for renewal, even as the echoes of past struggles remind us of the costs of war. The story of the Siege of Paris, with its blend of heroism, hubris, and heartbreak, continues to resonate, offering timeless insights into the human condition in times of crisis.

In the end, the Siege of Paris would last until January 1871, ending in French capitulation and the birth of the German Empire. But the memory of those autumn days—of snipers and armchairs, of ambitious generals and weary soldiers, of a city holding out against impossible odds—remains etched in history, a testament to the complexities and contradictions of war.
