Book summary “Moscow 1812”: summary

Introduction

You often view history through the lens of neat political strategies and inevitable outcomes. Adam Zamoyski shatters this illusion in Moscow 1812 by exposing how vanity, poor planning, and brutal weather created a human catastrophe.

You find yourself asking why a brilliant military commander led hundreds of thousands of men to their deaths without a clear political goal. The book traces the collision between Napoleon and Tsar Alexander I from the initial drift to war through the fatal occupation of Moscow.

• How did the Tilsit alliance collapse into inevitable war?
• Why did the invasion force lack basic logistical support?
• What caused the catastrophic disintegration of the Grande Armée during the retreat?

1. The Drift to War

Napoleon's wars were not merely fights over territory but formed part of a prolonged ideological struggle between the French Revolution and European monarchies. Revolutionary France exported Enlightenment ideals and subverted neighboring monarchies for survival, creating a perpetual cycle of fear where European powers deemed the regime intolerable. France endured nineteen years of virtual war before the March 1802 Peace of Amiens temporarily halted the fighting.

Napoleon's unyielding continental ambitions and the failure of the Tilsit alliance made a catastrophic war with Russia inevitable.

General Bonaparte seized power in November 1799 to rein in demagogues, and later executed the Bourbon Duc d'Enghien in March 1804 after accusing him of conspiring to restore the monarchy. Because Britain could not be defeated at sea or brought to the negotiating table without stability on the continent, neutralizing Russia's potential challenge to French authority was an absolute prerequisite for a permanent peace. While French society anticipated a golden age of peace following the birth of the King of Rome, Russia increasingly viewed war with France as desirable and unavoidable.

Caesar and the Continental System

The dynastic principle clashed directly with the new order. The author terms the ideal of a civilized European state under French guidance an état policé, which fundamentally threatened the traditional ancien régime. Neutralizing every rival became the only way to secure the regime against monarchical restoration.

The Polish Flashpoint

The Treaty of Tilsit forced Russia into a reluctant alliance with France and an economic war against Britain, while sowing the seeds of future conflict through the creation of the Grand Duchy of Warsaw. After suffering 25,000 men in losses at Eylau in January 1807 under Bennigsen, Alexander met Napoleon on a raft on the river Niemen to negotiate. On 7 July, the treaties were signed at the conclusion of Tilsit, and Alexander sent General Lobanov-Rostovsky to Napoleon's headquarters to propose a direct alliance without intermediaries.

The creation of the Grand Duchy of Warsaw introduced the first material conflict of interest, as it reignited fears of a restored Polish kingdom and threatened Russian security. A restoration risked 463,000 square kilometres of Russian acquisitions from Poland and a population of seven million inhabiting the Polish territories acquired by Russia. Furthermore, the introduction of the Code Napoléon threatened Russian landowners because it promised full emancipation of serfs, fueling paranoia among the Russian elite. When Austria went to war with France in 1809, Polish troops seized Galicia and Napoleon incorporated parts of it into the Grand Duchy, deeply alarming both Austrian and Russian courts.

Economic Pressures in Russia

The strict enforcement of the Continental System caused severe economic hardship in Russia, driving down the rouble and inflating the cost of everyday goods. Russia's lack of domestic industry made it dependent on imported goods, while bulky exports like timber and grain proved difficult to smuggle past the British blockades dictated by the Berlin decree.

• The Russian rouble suffered a 25 per cent drop in value against European currencies.
• Coffee prices more than doubled between 1807 and 1811.
• Sugar became more than three times as expensive during the same period.
• Champagne rose from 3.75 to 12 roubles per bottle.

These financial pressures placed immense strain on Russian noblemen who relied on imported luxuries. You can see how economic strangulation turned elite opinion firmly against the French alliance.

2. La Grande Armée and the Invasion

Napoleon assembled the largest military force in history but crossed the Niemen without a defined political purpose or adequate logistical support.

Composition of the Army

The Grande Armée was the largest force the world had ever seen, incorporating troops from almost every European nation under French generalship and discipline. While the core was French, Belgians, Dutch, Italians, Swiss, Poles, Germans, Austrians, Prussians, and smaller contingents swelled the ranks. Despite divergent national interests, the unifying factors were French military culture, the reputation of invincibility, and the psychological ascendancy of Napoleon.

Prussian officer Colonel Ziethen remarked that though the war was contrary to Prussian interests, military honour commanded him to fight at his allies' side.

The multinational force included:

• 95,000 Polish troops in the Grande Armée;
• 45,000 men in the Army of Italy;
• 24,000 Bavarian troops;
• 20,000 Saxon troops;
• 20,000 men in the Prussian auxiliary corps;
• 35,000 troops in the Austrian contingent under Prince Karl von Schwarzenberg.

Logistical Failures

Napoleon amassed colossal stockpiles of food, clothing, arms, and ammunition in forward depots to sustain hundreds of thousands of troops on campaign. Under the commissariat commanded by General Matthieu Dumas, vast quantities of rations, forage, and ammunition were gathered in northern Germany and Poland. However, moving these supplies presented an immense logistical nightmare due to the inadequacy of transport.

By January 1812, Napoleon amassed fifty-day supplies of provisions for 400,000 men and forage for 50,000 horses at Danzig alone.

The daily standard ration for a French soldier included:

• 550 grams of biscuit;
• 30 grams of rice;
• 60 grams of dried vegetables;
• 240 grams of meat or 200 grams of salt beef and lard.

By May 1812, the army amassed 761,801 rounds of ammunition for field artillery alone. Despite massive organizational efforts, the Grande Armée relied on extremely primitive and outdated basic weaponry that had remained unchanged for decades. The artillery still used the fifty-year-old Gribeauval gun, while infantrymen carried a muzzle-loading flintlock musket with a century-old design.

A trained soldier could reload and fire a musket in one and a half minutes, enduring hazards like the proverbial flash in the pan where powder ignited without firing the bullet.

You can reload the weapon using a systematic sequence:

• Take a cartridge containing a paper cylinder, powder, and a lead ball.
• Bite off the end of the cartridge, keeping the ball in your mouth.
• Sprinkle a little powder in the priming pan and close the flap.
• Pour the remaining powder down the barrel and spit the ball in after it.
• Screw up the paper into a wad and ram the whole lot down to the bottom with the ramrod.

Crossing the Niemen

Napoleon launched the 1812 campaign with the largest army ever assembled without a defined military or political purpose, making the conflict inherently impossible to win in a traditional sense. Napoleon gave vague and contradictory reasons for the war to his generals, ranging from throwing back barbarian hordes from the north to finishing things before he grew old. France had no territorial claims on Russia, and Napoleon was even willing to bolster Russian power if it helped defeat Britain, meaning the war lacked a rational foundation.

Napoleon told General Vandamme that he wanted to finish things because they were both getting old and he did not want people kicking him in the backside during his old age.

The overall paper strength of forces poised for invasion reached 590,687 men and 157,878 horses, representing 678,000 total French and allied troops in the whole theatre. Observers estimated the actual strength of the Grande Armée as it invaded Russia at 450,000 men, accompanied by a conservative figure of 50,000 civilians following the army. General Berthézène noted that the Guard never exceeded 25,000 despite being written up as nearly 50,000 strong.

On June 24, 1812, the Grande Armée crossed the Niemen River into Russian territory, marked by an impressive military spectacle and ominous omens. Napoleon secretly reconnoitered the riverbanks in disguise, suffering a fall from his horse which his chief of staff Berthier viewed as a bad omen. Despite the early forebodings, the actual crossing was executed with pontoon bridges amidst an elaborate display of full-dress uniforms and music, greeted by enthusiastic cries of Vive l'Empereur.

General Eblé and his men successfully installed three pontoon bridges near Kovno under the personal observation of Napoleon.

3. The Heart of Russia and Borodino

As Russian forces retreated into the vast interior, the brutal battle of Smolensk and the carnage of Borodino failed to break the Russian will to resist.

The Approach to Smolensk

Instead of crossing the Dnieper further upstream to cut off the Russian rear, Napoleon launched a costly grand assault against massive stone walls. Field artillery could not breach the walls that stood 25 feet high and 15 feet thick. The assault engaged 50,000 men from the Grande Armée.

Lieutenant Hubert Lyautey and Russian artillerists watered their horses side by side on opposite river banks during a temporary lull before exchanging cannon shots again.

The fighting caused fires that gutted the city of 12,600 inhabitants. French casualties reached 7,000 men killed and wounded. Russian forces lost 11,000 men in defending the city.

Kutuzov and the Defense

Kutuzov chose a diagonal position along the Kolocha river, stretching a front length of approximately 6 kilometres. He massed strong forces and earthworks on the right wing under Barclay. Bagration's Second Army on the left wing had minimal natural obstacles and relied on hastily built flèches.

Kutuzov placed Tuchkov's corps in the woods behind Utitsa to launch a secret flank attack. The corps contained 8,000 regulars, 7,000 Moscow militia, and 1,500 cossacks. Bennigsen accidentally stumbled on the position and repositioned it out in the open.

The Battle of Borodino

Nearly a thousand cannon spewing out charges at the start of the battle created a dense sea of smoke and dust. Troops on both sides endured relentless bombardments of solid iron ball shot weighing from 3 to 20 pounds, exploding shells, and canister shot that acted like giant shotgun cartridges. French artillery fired 91,000 rounds according to one source.

Sergeant Bourgogne of the Vélites of the Guard watched the bombardment from a safe distance, while other soldiers witnessed comrades cut in two and experienced an urgent need to defecate from sheer terror.

The intense slogging match over the V-shaped Bagration flèches turned the earthenworks into a bloody trap. The flèches were open at the back, holding an initial force of 18,000 defenders rising to over 30,000 with 300 guns. Once the French captured them, they were stuck in a funnel facing the next line of Russian troops with a wall at their backs. The earthworks were stormed, captured, and retaken seven times in three hours through ferocious hand-to-hand combat. Prince M.S. Vorontsov's Grenadier division was practically wiped out, losing 3,700 of its 4,000 men and all but three of its officers in two hours.

The extreme shortage of medical supplies turned the aftermath of the battle into a catastrophic amputation crisis.

Surgeons operated under improvised conditions, using stream water to wash instruments. Dr. Heinrich Roos and Dr. La Flise worked through the night by candle light, listening to screams and grinding teeth as limbs were sawed off without proper anesthesia.

Ten thousand wounded men were dumped in the Kolotskoie monastery. The mortality rate reached 75 percent among these unfortunates within eight to ten days due to lack of food and attention.

Surgeons followed a grim routine for amputations:

• Tie or hold the wounded man down on a table
• Give the patient a lead bullet, piece of wood, or leather to bite on
• Provide a shot of spirits to drink if available
• Cut through the skin, slice through muscles and nerves, and saw straight through the bone
• Sever arteries and leave the patient untended on the ground while severed limbs pile up

The morning after Borodino, Kutuzov could muster a maximum of 45,000 men for battle, alongside 45,000 estimated Russian casualties. During a tense council of war in Fili, generals like Bennigsen and Yermolov argued passionately over defending the city. Kutuzov brilliantly resolved to sacrifice Moscow in order to preserve the remaining Russian army from total destruction, using the city as a sponge to absorb the enemy.

4. The Occupation and Burning of Moscow

The occupation of an abandoned and burning Moscow left Napoleon in a political vacuum without levers to force Tsar Alexander to sue for peace.

Entry into Moscow

French troops reached Poklonnaia hill on 14 September 1812 and beheld Moscow's exotic splendor and vast scale. Sergeant Adrien Bourgogne and Lieutenant Fantin des Odoards recalled the initial jubilation giving way to a sinister solitude as no citizens or authorities came out to greet the marching bands. Napoleon was baffled to find the city largely evacuated and left to him unconditionally.

The Great Fire

Before leaving, Rostopchin ordered the evacuation of all fire pumps and instructed police and officials to torch supplies and buildings. On 15 September, large parts of Moscow caught fire. By 4:00 AM on 16 September, the fire reached the Kremlin walls, forcing Napoleon to flee to the Petrovskoie palace. Dr Larrey and General Dedem de Gelder described the terrifying spectacle of colored flames, flying tin roofs, and wounded Russian soldiers dragging themselves out of burning hospitals. Napoleon rode back into Moscow on 18 September after the fire began to abate.

Strategic Impasse

Napoleon found himself trapped in a political vacuum, unable to find negotiators, gather intelligence, or force Tsar Alexander to treat for peace. Caulaincourt noted that not a single person could be found for silver or gold to carry a message to St Petersburg or infiltrate the Russian army. On 20 September, Napoleon wrote a letter to Alexander and met with Yakovlev.

Field Marshal Kutuzov executed a brilliant flanking march to establish a fortified camp at Tarutino, using the time gained to rebuild the army and boost morale.

You can adopt the recovery methods used at the Tarutino camp:

• Dig pits and construct banyas (Russian steam-baths) to clean up and relax.
• Order winter uniforms including thick trousers, sheepskin coats, fur-lined boots, and gloves.
• Issue regular propaganda bulletins (Izvestia iz Armii) to highlight skirmish successes and troop well-being.

Napoleon fell victim to self-delusion regarding the climate and political consequences of retreat, paralyzing his decision-making. Napoleon teased Caulaincourt for being frightened of the Russian winter, claiming it was warmer than Fontainebleau at that time of year. On 13 October, the first light snow shower shook Napoleon into realizing he must hurry.

Prudent officers and Polish units gathered sheepskin coats, built tents, and sharp-shod their horses with crampons for winter conditions. Józef Grabowski noted that Polish units made horseshoes with sharp crampons, but their advice bounced off Gallic unconcern among the French.

You can follow these winter preparations to survive harsh conditions:

• Acquire rough sheepskin coats from local peasants
• Procure fur-lined overboots, gloves, and fur caps
• Equip horses with horseshoes featuring sharp crampons for winter

5. The Empire of Death and the Retreat

The onset of bitter winter conditions turned the retreat from Moscow into an unprecedented human catastrophe marked by starvation, freezing, and military disintegration.

The arrival of freezing temperatures and heavy snow on 6 November destroyed the cohesiveness of the army and introduced mass hypothermia. French uniforms were flimsy, short-cut, and unlined, providing no defense against sub-zero weather, leading entire groups of men to freeze to death around their bivouac fires.

Faber du Faur found entire units of Württembergers sitting dead and frozen stiff around their campfires.

With foraging impossible and cooking equipment scarce, men consumed raw or crudely boiled substitutes, leading to widespread digestive illnesses. You can follow this improvised recipe for the Spartans' Gruel:

• Melt a large quantity of snow to produce a little water.
• Mix in flour.
• Add axle grease in the absence of fat.
• Add gunpowder in the absence of salt.
• Serve hot and eat when very hungry.

The extreme cold caused a massive plague of frostbite because soldiers from milder climates did not recognize the warning signs or know how to treat them properly. Soldiers made the fatal mistake of warming numb extremities directly at campfires or in houses, which induced instant gangrene; the affected body parts turned purple and snapped off. Captain François watched in disbelief as a friend unwrapped his footwear and three toes broke away without causing any pain. You can prevent this condition by following this rule:

• Rub the afflicted part vigorously with snow until circulation is restored.

The Berezina Crossing

Dutch pontoneers under General Eblé constructed two essential bridges across the icy Berezina River under extreme conditions of freezing water and floating ice blocks. Despite burning the main pontoon train earlier at Orsha, Eblé saved six tool wagons and two field smithies. His sappers dismantled houses in Studzienka for logs while 400 pontoneers, mostly Dutchmen, stripped to their pants and waded into the icy current, enduring hypothermia to drive 23 trestles into the riverbed. The first completed bridge reached dimensions of 100 metres long and about four metres wide.

Grenadier and painter François Pils recorded how the Dutch pontoneers went into the water up to their necks with unmatched courage while some fell dead and were swept away. Panic, Russian shelling, and overwhelming numbers created a deadly crush at the bridge approaches, leading to massive civilian and military casualties before Eblé burned the bridges. As Russian shells rained down on the massive throng of wagons, non-combatants, and stragglers, a frantic stampede ensued. People and horses were trampled, crushed, or forced into the freezing river. General Eblé delayed burning the bridges until the absolute last moment before enemy troops arrived, leaving thousands stranded on the eastern bank.

Sergeant Bourgogne watched a cantinière holding her husband and child get pushed into the icy water, while Lieutenant Carl von Suckow described the horrific sensation of walking over living beings who clutched at his legs. The operation resulted in 25,000 total French losses estimated over the three days of the crossing. Of these, 10,000 of the French losses consisted of non-combatant stragglers, while 15,000 Russian losses were inflicted entirely in combat.

Physiological Collapse and Cannibalism

Extreme cold profoundly altered human physiology and behavior, causing severe frostbite, sensory loss, and an eerie atmosphere of tiny floating icicles that made breathing and vision hazardous. Temperatures dropped to -30°C (-22°F) at Pleshchenitse on 30 November, and further down to -37.5°C (-35.5°F) at Miedniki on 6 December. Soldiers suffered severe frostbite where the skin and muscle peeled away like waxwork layers, leaving exposed bones while the victims remained temporarily insensitive to pain. The air filled with tiny ice crystals that cut the skin like needles, froze soldiers' eyelids shut, and formed massive icicles from their saliva and breath.

Dr Louis Lagneau recorded minus 30 degrees Celsius at Pleshchenitse on 30 November and minus 37.5 degrees Celsius at Miedniki on 6 December, while Louis Lejeune described soldiers whose skin peeled away like waxwork figures. Driven by ravening hunger and the complete breakdown of psychological barriers, starving soldiers and prisoners resorted to cannibalism, consuming the flesh of dead comrades and enemies. While early reports of cannibalism during the retreat mostly came from Russian accounts observing French victims and prisoners, first-hand French accounts eventually confirmed the practice. Starving men ate horse carcasses, cats, dogs, carrion, and human flesh, cutting strips of meat from thighs or consuming stew containing human liver.

Lieutenant Roman Soltyk reached Orsha and unknowingly swallowed a spoonful of human stew containing a human liver before being told the truth by the men cooking it.

The End of the Road

The campaign resulted in the death of approximately one million people, split evenly between the invading and defending sides. Between June 1812 and February 1813, out of 550,000 to 600,000 total French and allied troops operating beyond the Niemen, roughly 400,000 died, with less than a quarter in battle. Russian military and civilian losses reached similar catastrophic scales, totaling 400,000 Russian soldiers and militia dead, including 110,000 in battle. The total death toll across all combatants and civilians reached 1 million.

Of the 52,000 men of the Army of Italy, only 2,637 men and 207 officers reassembled at Marienwerder in January. Only 120,000 troops came out in December, while the Russians took 100,000 prisoners, of whom about 20,000 survived.
