French invasion of Russia
The French invasion of Russia, also known as the Russian campaign, the Second Polish War, and in Russia as the Patriotic War of 1812, was initiated by Napoleon with the aim of forcing the Russian Empire to comply with the continental blockade of the United Kingdom. Widely studied, Napoleon's incursion into Russia remains a focal point in military history, recognized as among the most devastating military endeavors to ever unfold. In a span of less than six months, the campaign exacted a staggering toll, claiming the lives of nearly a million soldiers and civilians.
Beginning on 24 June 1812, the initial wave of the multinational Grande Armée crossed the Neman River, marking the entry from the Duchy of Warsaw into Russia. Employing extensive forced marches, Napoleon rapidly advanced his army of nearly half a million individuals through Western Russia, encompassing present-day Belarus, in a bid to dismantle the disparate Russian forces led by Barclay de Tolly and Pyotr Bagration totaling approximately 180,000–220,000 soldiers at that juncture. Despite losing half of his men within six weeks due to extreme weather conditions, diseases and scarcity of provisions, Napoleon emerged victorious in the Battle of Smolensk. However, the Russian Army, now commanded by Mikhail Kutuzov, opted for a strategic retreat, employing attrition warfare against Napoleon compelling the invaders to rely on an inadequate supply system, incapable of sustaining their vast army in the field.
In the fierce Battle of Borodino, located west of Moscow, Napoleon was not able to beat the Russian army and Kutuzov could not stop the French. At the Council at Fili Kutuzov made the critical decision not to defend the city but to orchestrate a general withdrawal, prioritizing the preservation of the Russian army. On 14 September, Napoleon and his roughly 100,000-strong army took control of Moscow, only to discover it deserted, and set ablaze by its military governor Fyodor Rostopchin. Remaining in Moscow for five weeks, Napoleon awaited a peace proposal that never materialized. Due to favorable weather conditions, Napoleon delayed his retreat and, hoping to secure supplies, began a different route westward than the one the army had devastated on the way there. However, after losing the Battle of Maloyaroslavets, he was compelled to retrace his initial path.
As early November arrived, snowfall and frost complicated the retreat. Shortages of food and winter attire for the soldiers and provision for the horses, combined with guerilla warfare from Russian peasants and Cossacks, resulted in significant losses. More than half of the soldiers perished from starvation, exhaustion, typhus, and the unforgiving continental climate.
During the Battle of Krasnoi, Napoleon faced a critical scarcity of cavalry and artillery due to severe snowfall and icy conditions. Employing a strategic maneuver, he deployed the Old Guard against Miloradovich, who obstructed the primary road to Krasny, effectively isolating him from the main army. Of the French commanders, Davout successfully broke through, whereas Eugene de Beauharnais and Michel Ney were forced to take a detour. Despite the consolidation of several retreating French corps with the main army, by the time he reached the Berezina river, Napoleon commanded only around 49,000 troops alongside 40,000 stragglers of little military significance. On 5 December, Napoleon departed from the army at Smorgonie in a sled and returned to Paris. Within a few days, an additional 20,000 people succumbed to the bitter cold and diseases carried by lice. Murat and Ney assumed command, pressing forward but leaving over 20,000 men in the hospitals of Vilnius. The remnants of the principal armies, disheartened, crossed the frozen Neman and the Bug.
While exact figures remain elusive due to the absence of meticulous records, estimations varied and often included exaggerated counts, overlooking auxiliary troops. Napoleon's initial force upon entering Russia exceeded 450,000 men, over 150,000 horses, approximately 25,000 wagons, and nearly 1,400 artillery pieces. However, the surviving count dwindled to 120,000 men, signifying a staggering loss of approximately 380,000 lives throughout the campaign, half from diseases. This catastrophic outcome shattered Napoleon's once-untarnished reputation of invincibility. Russian losses were nearly as large, with the campaign whittling down their field army to 40,000 effectives by the time they reached the Niemen River. With the considerable resources of the French Empire at his disposal, Napoleon quickly went about reconstituting his army, but in this moment of opportunity Austria and Prussia switched sides to that of Russia and Britain, greatly shifting the balance of power and triggering the War of the Sixth Coalition.
Names
The French invasion is known as the Russian campaign, the Second Polish War, the Second Polish campaign, the Patriotic War of 1812 in Russia, or the War of 1812. It should not be confused with the Soviet term for the German invasion Operation Barbarossa during the Second World War, the Great Patriotic War. The "Patriotic War of 1812" is also occasionally referred to as simply the "War of 1812", a term which should not be confused with the conflict between Great Britain and the United States, also known as the War of 1812. In Russian literature written before the Russian revolution, the war was occasionally described as "the invasion of twelve nations". Napoleon termed this war the "Second Polish War" in an attempt to gain increased support from Polish nationalists and patriots. Though the stated goal of the war was the resurrection of the Polish state on the territories of the former Polish–Lithuanian Commonwealth, in fact, this issue was of no real concern to Napoleon.Background
From 1792 onwards, France found itself frequently embroiled in conflicts with major European powers, a direct aftermath of the French Revolution. Napoleon, rising to power in 1799 and assuming autocratic rule over France, orchestrated numerous military campaigns that led to the establishment of the First French Empire. Starting in 1803, the Napoleonic Wars served as a testament to Napoleon's military prowess. He secured victories in the War of the Third Coalition, the War of the Fourth Coalition, and the War of the Fifth Coalition.In 1807, following a French triumph at Friedland, Napoleon and Alexander I of Russia signed the Treaty of Tilsit along the Neman River. These treaties progressively solidified Russia's alignment with France, allowing Napoleon to exert dominance over neighboring states. The accord rendered Russia an ally of France, leading to their adoption of the Continental System, a blockade aimed at the United Kingdom. However, the treaty imposed significant economic strain on Russia, prompting Tsar Alexander to break away from the Continental blockade on December 31, 1810. This decision left Napoleon without his primary foreign policy tool against the United Kingdom.
The Treaty of Schönbrunn, concluding the 1809 conflict between Austria and France included a clause that transferred Western Galicia from Austria and annexing it to the Grand Duchy of Warsaw. This move was seen unfavorably by Russia, perceiving the territory's annexation as a potential threat for a French invasion point. Russia's foreign Minister Nikolay Rumyantsev advocated a closer alliance with France in response.
In an attempt to secure greater cooperation from Russia, Napoleon initially pursued an alliance by proposing marriage to Anna Pavlovna, the youngest sister of Alexander. However, he ultimately married Marie Louise, the daughter of the Austrian emperor. Subsequently, France and Austria solidified their relationship by signing an alliance treaty on 14 March 1812.
In March 1811, Marshal Davout received orders to clandestinely prepare for a demonstration of military strength aimed at impressing Russia. This plan involved deploying troops to Magdeburg and occupying the Baltic ports Stettin and Danzig. During this period, Napoleon's physical and mental condition underwent changes. He experienced weight gain and increasing susceptibility to various health issues. In May 1812 he left his palace in Saint-Cloud; one month later he arrived in Toruń.
Russian military reforms
The Russians did not sit idle and learned from previous defeats which included Austerlitz and Friedland. Construction of fortresses began in Dinaburg and Bobruysk, fortresses in Kiev and Riga were reconstructed, new rear food supply depots were established, and military reforms were carried out in 1810–1812. The highest military administration was transformed: in January 1812, the "Institution for the Administration of the Large Active Army" was adopteda new regulation on field troop command that managed the activities of army headquarters. The divisional system was improved, and the corps system was officially established for the first time in the Russian Army. On the initiative of Barclay de Tolly, troop training in aimed fire and actions in skirmish formations was organised. Military intelligence agencies were created: the Secret Expedition under the Minister of War and the Supreme Military Police ; positions of military attaché were introduced at Russian embassies. Based on military intelligence, Barclay created offensive plans in case of a new possible war. The Arakcheyev artillery system was introduced in exchange for the Shuvalov system.Declaration of war
Committed to Catherine the Great's expansion policy, Alexander I issued an ultimatum in April 1812, demanding the evacuation of French troops from Prussia and the Grand Duchy of Warsaw. When Napoleon chose war over retreat, between June 8 and 20, the troops remained in constant motion, enduring arduous marches amid intense heat. Napoleon's primary objective was to defeat the Imperial Russian Army and compel Czar Alexander I to rejoin to the Continental System. From 21 to 22 June 1812, Bonaparte stayed at Vilkaviškis Manor. There Napoleon announced the following proclamation:Soldiers, the second Polish war is begun. The first terminated at Friedland, and at Tilsit, Russia vowed an eternal alliance with France, and war with the English. She now breaks her vows and refuses to give any explanation of her strange conduct until the French eagles have repassed the Rhine, and left our allies at her mercy. Russia is hurried away by a fatality: her destinies will be fulfilled. Does she think us degenerated? Are we no more the soldiers who fought at Austerlitz? She places us between dishonour and war—our choice cannot be difficult. Let us then march forward; let us cross the Neman and carry the war into her country. This second Polish war will be as glorious for the French arms as the first has been, but the peace we shall conclude shall carry with it its own guarantee, and will terminate the fatal influence which Russia for fifty years past has exercised in Europe.
