Napoléon‘s role in this battle should be understood as a prelude to the battle of Eylau. A French general born in Corsica, Napoleon Bonaparte is one of history’s most distinguished leaders. Napoleon illuminated the French nation when it was lost in darkness. He led France to victory in myriad wars as a military thinker. He contributed in a way that changed the course of history. Napoleon was at the height of his power in 1807. Russia declared war on France the same year. Russian armies destroyed French forces ruthlessly and stubbornly. The Battle of Eylau in February 1807 pitted French and Russian troops against each other. Ultimately, the battle was drawn out.

The tale of Napoleon on the battlefield of Eylau includes a look at his strategy and tactics and the warfare itself.

Historically, this was one of the most brutal and unresolved battles of the French Revolution. Having been against Napoleon’s rule, the British invested in countries that could fight the French. The British supported a syndicate formed by Austria, Russia, Sweden, Poland, and Germany to destroy Napoleon’s empire. Napoleon aimed to unify Europe’s nations under French rule. Russia dominated these regions. The conquest of Germany gave Napoleon the belief that he could do anything. As his rage grew, he headed east from Germany. Consider the events that brought him back for a Prussian campaign. 

WARFARE REVOLUTION

The French Revolution and the Napoleonic Wars profoundly influenced warfare. Several wars were triggered during the 19th century. They pioneered military capabilities in the 19th and 20th centuries. They symbolize the change from royal armies to general public troops. Rather than between monarchies, wars became between countries. Napoleon controlled France and its surrounding nations, giving him tremendous military power.

THE BEGINNING 

Prussia resisted joining the syndicate in 1805. By threatening to deliver an ultimatum, Napoleon persuaded Austria’s army and people to withdraw from southern Germany in 1806. Napoleon marched against Prussia in response. His vision of destroying the syndicate began in Austerlitz. As a result of Austerlitz’s defeat, Austria resigned from England, Sweden, and Russia’s syndicate against France. For his policy to succeed on the continent, he must defeat Russia in the same manner as Austria and Prussia. France, Italy, and the River Union provided recruits, while Austria and Prussia offered financial support.

GROUPING FOR BATTLE 

Since 1796, Napoleon has ruled European warfare. His victory on the battlefield allowed him to assemble a large army ready for battle at any time. Military chroniclers often overlook the Battle of Eylau. Napoleon used extensive measures over the winter of 1806 and 1807 to influence the French troops to follow his plans in Poland. As he fought, he knowingly juggled the circumstances surrounding his grand army and the unstable political situation. A superior Russian army was too powerful for Napoleon’s powerful armed forces during the winter of 1806-1807. In the empty spaces of Poland, Napoleon’s system of living off the land failed for the first time; and the large armed forces were drained, and the spirits were low.

NAPOLEÁN’S GRAND ARMY 

The Grand Army in Poland included a considerable horse reserve and the Royal Legion. Corps were the backbone of the Grand Army. Marshals command semi-permanent military units in France. The force size will be determined by the number of rifle and horse battalions assigned. In addition to increasing agility and responsiveness, corps may also identify with their units, thus enhancing confidence. Horseback riders, guns, and soldiers formed smaller groups and battalions in these enormous forces. Units are made up of squadrons, while corps are made up of battalions. By combining weaponry, operational flexibility was provided. As in Napoleonic warfare, rapid conflict readiness and a fast march were crucial. If the enemy attacked another corps, his armies should be close together so one could protect the other. Before a battle, at least one unit should be placed on the enemy’s side. Due to the communication blockade, the enemy retreated from the battlefield. Since 1796, Napoleon has ruled European warfare.

THE RUSSIAN AND PRUSSIAN ARMIES : France’s adversaries used the Prussian linear warfare strategy. The Russian imperial army had 14 divisions. They had larger units than their closest competitors. Each unit had 18-20 rifle battalions, 30 to 35 horse troops, and five to six gun crews. Russia sent five units against the Turks in late 1806: two to St. Petersburg and one to Finland. General Bennigsen moved four units from Prussia under Buxhowden on October 29. Russian regiments were composed of three battalions and led by captains. Wagons deliver all the unit’s supplies during a campaign. Despite this, their supply carts were excellent. Their horses received special care due to a hereditary tradition. Despite severe weather, Russian horses were plentiful and bushy. As long as there was no wind, native horses could survive almost anywhere.The battalions were divided into sections or units for movement. Horse riders, regular soldiers, and heavy weapons were divided into elite units the night before a battle. The senior commanding general merged these units into temporary battalions. Thus, the adequate firepower of authorized foot armor units was reduced by two rounds per battalion. It ensures maximum flexibility in the field so that exhausted regiments are not forced to fight because their division is engaged. An active corps can be organized on the spot to carry out the task. However, such antiquated methods of warfare should have prioritized successful contact during combat. There was no strategic adaptability at any level above the unit because of the authority and charge system. Moving near an enemy with inexperienced troops led to various terrible things.

The Prussians were the dominant force of the 18th century during Frederick II’s reign. In just 50 years, Frederick’s army transformed a modest kingdom into a world power. The Prussian army was highly trained and organized. Despite massive odds, they succeeded. One of the most significant flaws was poor military leadership. Many targets have suffered catastrophic damage from carrying units separately and unaided.

Sections or units formed the movement of battalions. The night before a battle, horse riders, regular soldiers, and heavy weapons were divided. The commanding general included temporary divisions. Two rounds per battalion reduced the authorized foot armour units’ firepower. It prevents exhausted regiments from fighting because their division is engaged in combat. It is possible to organize a corps on the spot. This antiquated method of warfare, however, placed priority on successful contact. Because of the authority and charge system, there needed to be more strategic adaptability. It could have been better to move near an enemy with inexperienced troops. During Frederick II’s reign, the Prussians dominated. It took Frederick 50 years to transform a modest kingdom into a world power. Prussia’s army was highly trained and organized. It was a victory despite enormous odds. The poor military supervision was a significant flaw. Carrying units separately and unaided has left many targets badly damaged. Frederick Wilhelm’s ineffective and weak tactics pushed Prussia into war. After declaring war on Napoleon in October 1806, Prussia was destroyed a few weeks later. Napoleon defeated Frederick Wilhelm’s main army and Jena’s large reserves at Austerlitz. Jena and Austerlitz marked the end of the Prussian army. A few survivors fled but were captured and killed.

INITIAL STAGE OF THE WAR 

Napoleon captured the main German towns after defeating the Prussian army at Jena-Auerstedt. The majority of them were Russians under Field Marshal Mikhail Kamensky. The Marshal withdrew because he refused to fight. Across the Vltava River, the French discovered Russians guarding the Wkra River line. As part of the Battle of Czarnowo, the French captured a bridge over the Wkra. Russian defenses had become stronger during the Battles of Putusk and Golymin on December 26. After a successful but difficult battle, Napoleon’s army stayed in Poland.

Newly appointed Russian army commander Levin August, Count von Bennigsen, moved most of his forces away from Nowogród to East Prussia. As a result of Napoleon’s tactical ingenuity, he took advantage of a potential opportunity. As Napoleon arrived, Marshal Michel Ney’s Corps members defied orders and moved far north. The Prussians supported him. After Ney withdrew his troops, Russian forces attacked Bernadotte’s sole French troop. At the Battle of Mohrungen, Bernadotte’s regiment escaped severe harm. In addition, Bernadotte was instructed to leave before Bennigsen’s troops arrived. This operation will trap the Russian army on its left side, preventing it from retreating.

On February 3, Soult’s IV Corps marched into Bennigsen’s left rear during his rapid advance at Jonkowo. On that day, Lieutenant General Nikolay Kamensky’s 14th Division faced General Jean François Leval’s Division in Bergfried. The French killed 1,100 opponents but only 306 of their citizens. After capturing Allenstein, Soult headed north. From the south, Marshal Pierre Augereau’s soldiers threatened Bennigsen. Three Prussian riflemen and four Russian battalions held the west bank. Bergfried and its bridge were captured after the French stopped an earlier attack. Russians briefly retook the bridge during the offensive. During that night, the French occupied the field, and Soult claimed 800 Russian remains had been recovered. After a terrifying march, Bennigsen retreated to Wolfsdorf. On his way back to Landsberg, he passed Burgerswalde. A few days into February, the French army was seeking to capture the Russian military, which had already fled. Following the failure of several attempts to stand and fight, Bennigsen moved to Preussisch-Eylau and fought there. Due to the poor condition of Polish roads, the harsh winter weather, and the ease with which his soldiers dealt with Prussia, Napoleon allowed his Grand Army to spread out more than usual during the chase. In contrast, Bennigsen had already mastered his tactics.

WAR’S FIRST DAY 

Marshal Soult’s IV Corps and Marshal Murat’s horse riders were the first French units to reach the ridge before Eylau. The Russian squad of Prince Bagration set troops on the ridge about a mile ahead of Eylau. The French made an early charge against these strongholds but were repelled. Bagration was told to put up a vigorous fight to allow Bennigsen’s heavy weapons time to pass through Eylau and rejoin the Russian Army beyond Eylau. Under the strain of vastly superior forces, Bagration withdrew efficiently to rejoin the main army. The withdrawal was delayed by Barclay de Tolly’s reinforced counterattack unit in Eylau. During the afternoon, the Imperial Guard and Marshal Augereau’s army supplied approximately 45,000 men to the French.

Throughout Barclay’s assault on Eylau, French soldiers engaged in defensive combat. Soult and Murat failed to provide adequate protection for the town to allow soldiers to sleep comfortably throughout the winter. The troops may be able to find refuge on their own. Captain Marbot reported that the Emperor preferred to battle in the dark rather than at night. In front of Eylau, the high ground was a convenient place to wait for reinforcements because Davout’s Corps was on his right and Ney’s Corps was on his left.

Despite the cause, After being shot in the arm, Barclay left the battlefield after being shot in the arm and was among approximately 4,000 casualties on both sides during the battle for the town. A French brigadier general named Pierre-Charles Lochet and other officers were shot and killed. Bennigsen ordered the Russians to move back a short distance at 22:00, handing over the town to the French. Afterwards, Bennigsen stated that he left the city to have the French attack his center the following day. Despite their control of the town, most French and Russians slept outside. The Russians were due to their usual disorder, and the French were expected to have road and weather problems. Because of the overwhelming number of troops rushing to the battlefield, both sides were without food. Over the course of the night, Bennigsen strengthened his reserve by withdrawing some of his forces from the front line. This action resulted in a reduction in the length of his right wing.

WAR’S SECOND DAY 

Only 49,000 French soldiers and 300 firearms were on hand, while Bennigsen had 67,000 Russian soldiers and 400 guns. Anton Wilhelm von L’Estocq’s disconnection may provide additional support for the Russians; the Prussians had Marshal Ney’s 14,000-man VI Corps following the French and Marshal Davout’s depleted III Corps with Auerstedt triumphant. Bernadotte’s I Army was sufficiently distanced from the enemy. Continuous snowfall, mild temperatures, and no change in visibility during daylight hours characterized the day. Battle lines were drawn along two parallel ridges. French forces began investigating the Russian position as soon as possible, especially on the right side. To begin the battle, Bennigsen ordered his firearms to fire on the French as he was concerned the French would notice he had shortened his right arm. Due to their dispersed positions, the French won the long-range battle.

As the firearms duel began, Napoleon became furious. Up to that point, he had anticipated the Russian pullout to continue. An order was sent to Ney instructing him to attack Eylau and join the French left wing. The French had occupied some grain mill buildings in the Russian right wing’s musket range. In the area, Russian forces expelled the French. As the battle escalated, the Russians attacked the French left wing on Windmill Knoll, left of Eylau. Napoleon figured they would shoot Eylau from his left after heeding their actions. On the Russian left wing, Davout’s III Corps was arriving. Napoleon threw the attack with Augereau’s VII Corps on the left and Saint-Hilaire’s Division of Soult’s IV Corps on the right to control the alleged Russian attack on Eylau. Due to his illness, Augereau had difficulty getting on his horse. Fate intervened and ended the attack. When the French left, a snowstorm fell, which caused everyone to lose all sense of direction. Taking a left turn away from Saint-Hilaire, Augereau’s unit followed the slope of the land. At the intersection of Augereau’s march, the blinded French and the extended Russian gunner opened fire on the Russian line. It would have been more effective if Saint-Hilaire’s division had marched alone against the Russian left.

Marbot took the flag of the 14th army, which failed to retreat. Augereau listed 929 dead and 4,271 wounded as blocks of bodies. By reducing his horses to Saint Hilaire’s unit and placing his backups, Bennigsen took advantage of this situation. At Eylau, Augereau and the survivors faced 5,000 Russian soldiers. Using the church tower as a watch post, Napoleon nearly fell to the Russians. He carried them off sufficiently to allow some Guard battalions to attack. The Russian column was almost exterminated when Bruyère’s horses reacted to their charge. The French center was in disarray, almost vulnerable, and under threat within four hours. Napoleon raised his 11-thousand-strong horse riders to support, including the French Guards, the last intact force of the French army, in this situation. He almost broke in the middle.

THE CONCLUSION 

It was about 10 p.m. when the battle ended, a few hours after it had begun to darken. As both armies planned to disperse that night, the Russians took the lead. Napoleon was able to keep control of the battlefield. He could declare victory without fully knowing how tight the battle had been.

The situation is uncertain on both sides. The Russians killed 7,000 people and injured 12,000-15,000 people, whereas Napoleon killed 1,900 people and injured 5,700. Unsurprisingly, this estimation of French losses was drastically exaggerated, as the phrase puts it, “to lie like a bulletin.” French commanders confirmed even more deaths: Davout lost 5,007 lives, Augereau lost 5,200, including prisoners, and Soult lost 8,250. It is believed that more than 15,000 people died due to the war, including horse riders. It is calculated that the French lost 25,000 soldiers, while the losses of Augereau were almost five times as large.

Bennigsen reported 20,000 casualties on the Russian side, including 12,000 deaths and 7,900 injuries. In the end, it is generally believed that his total damages were only $15,000. He won the decisive victory at Friedland on June 14, 1807), but severe fighting began in the summer. After the battle, the Russians returned to their supply warehouses in Königsberg. Despite a slow response, the French won a horseback fight at Friedland. In Ostrolenka, further south, they defeated Essen on February 15. Additionally, they attacked Danzig, but both armies had entered winter quarters by the end of February.

The Battle of Eylau was Napoleon’s first major defeat on the battlefield. The Russian army’s resilience and the harsh cold climate in Poland thwarted him from securing a decisive victory. The success of Napoleon’s army was largely dependent upon its ability to focus on the battlefield while moving in a fragmented manner. It was impossible at Eylau, and the French were overpowered throughout the battle. Davout was the only one to reach on time among Napoleon’s three backup units. Bernadotte and Ney could only get to the battlefield after the conflict ended. During the Battle of Eylau, Napoleon discovered the first flaws in his military reputation, which greatly emboldened his European opponents.
