text: It thus became clear to the Archduke that another battle would be forthcoming, although he still nourished hopes that Napoleon himself might make peace overtures. Although morale among the rank and file remained fair following Aspern-Essling, the atmosphere among the Austrian senior commanders was particularly rotten and Charles's insufficiently assiduous preparations for another battle further sapped their confidence in him. One of the senior generals, Johann von Hiller, commander of VI Korps was overtly critical of Charles's strategy and resigned on 4 July, on the eve of the battle of Wagram, giving health reasons as a pretext. Archduke Charles did make considerable efforts to rebuild his army and, despite the slow arrival of reinforcements, by the end of June, it was close to full strength again. Overall, Archduke Charles was well aware that he did not possess the means necessary to lead any offensive actions, so he promptly dismissed suggestions to run any major operations against the French base on Lobau island. A plan to march to Pressburg, cross the Danube and launch operations against the enemy's rear from there was also dismissed as strategically unsound after "General Major" Wimpffen noted that such a plan would leave Bohemia, the richest province still under the Austrian Empire's control, open to a French invasion. By the end of June, Archduke Charles was still hoping that Napoleon might opt to negotiate, a misapprehension that the latter encouraged through a series of ruses. In the event that a battle would indeed occur, Charles planned to remain on the defensive and thus his actions depended on the moves of the enemy. A member of the House of Habsburg, Archduke Charles saw the army as an invaluable tool, meant to protect the existence of the Monarchy. He was thus a cautious commander, never willing to risk it all in order to obtain a decisive victory, a commitment that he reiterated towards the end of June, when he wrote to his uncle and mentor, Prince Albert of Saxony, Duke of Teschen, stating that, should another battle be unavoidable, he would "strike one more blow against the French" but "risk nothing or as little as possible". Although he reckoned that Austria would need a major victory in order to turn the tide of the war, he believed that another battle against Napoleon would have doubtful results.


title: Battle of Wagram

text: Meanwhile, having retreated to the island of Lobau after the battle of Aspern-Essling, Napoleon knew that he had failed in his attempt to cross the Danube and was so astonished by the severity of the setback that he remained in unaccustomed inaction for 36 hours. After recovering his usual drive, his immediate concern was to improve the dire situation of his army, which was in very bad shape and virtually trapped on Lobau island, after the Danube had swollen. With his usual tireless activity, he supervised the transformation of Lobau island into a huge army base. The French built temporary campaign hospitals for his 20,000 wounded, as well as warehouses and barracks, which sheltered a numerous permanent military garrison. As soon as a secure bridge was built, the Emperor had the wounded and a part of the troops transferred to the mainland, but maintained IV Corps on the island. He did not intend to abandon this position, as he was planning to use it as a springboard for his upcoming crossing. His next task was to rebuild the army. Casualties had been roughly equal to those of the enemy, but, with fewer troops engaged, some of Napoleon's battalions needed rebuilding from scratch. Losses in officers in particular had been extremely high and proved difficult to replace. "Maréchal" Jean Lannes, one of Napoleon's ablest commanders and a personal friend, had been mortally wounded in action and died nine days after the battle. Another irreplaceable loss was Louis-Vincent-Joseph Le Blond de Saint-Hilaire, who had been created a Marshal of the Empire just a month before, in recognition of his brilliant conduct during the earlier campaign, but received a mortal wound during the battle and died before the coveted baton could arrive from Paris. Jean-Louis-Brigitte Espagne, another famous general was killed in action at the head of his "cuirassiers" and the commander in chief of the artillery, Nicolas-Marie Songis des Courbons, became severely ill and had to leave his command a few weeks after the battle. Despite all these setbacks, the army and its officers retained total confidence in Napoleon's ability to lead them to victory and morale remained high. Evidence of this came a couple of days before the newly planned crossing of the Danube, when Napoleon's most senior Corps commander, "Maréchal" André Masséna fell from his horse and badly injured his foot, rendering him unable to ride for some time. In sheer contrast with Hiller's gesture, Masséna, although in significant pain, made arrangements to lead his men in battle from a phaeton and vowed to retain his command, much to the Emperor's relief.


title: Battle of Wagram

text: Napoleon reckoned that he would need careful planning and superior forces, before he could attempt another crossing of the Danube. In order to achieve that, he needed to secure his island-base at Lobau. Following the Emperor's orders, the commander of the Grande Armée artillery, General Songis and his successor, General Lariboisière, installed a massive 124-gun battery on the island. They also carefully scouted the shores and small islands of the Danube and installed batteries in strategic positions, in a bid to cover Vienna, but above all with the aim of keeping the enemy guessing about the exact location of the upcoming crossing. The French also needed reliable bridges. Starting work on 1 June, General Bertrand led vast military engineering works that resulted in the building of two strong bridges from the south bank to Lobau island. These were to be used to transfer supplies and troops onto the island. Bertrand secured these bridges against any floating barges that the Austrians might have launched to destroy them, by building palisades upstream. In order to cross from the island to the northern bank, a series of pivoting bridges and landing craft were also built. The French also captured a Danube flotilla and built additional patrol ships, which meant that they were, by the end of June, in almost complete control of the river, allowing Napoleon to write in the Army Bulletin of 2 July that "the Danube no longer exists for the French army".


title: Battle of Wagram

text: The Austrian high command was well aware of the French preparations on Lobau island and thus understood that the French attack would come from there. Archduke Charles was however unsure about where the French would cross and, together with his staff reckoned that the crossing would most likely be made from the north of the island, making landfall roughly at the same location as at the Battle of Aspern-Essling. Working on this hypothesis, Charles had a chain of 16 defensive redoubts built, essentially between Aspern and Groß-Enzersdorf. Strangely, he did not extend the earthworks southeast, along the riverline, which meant that the line could be outflanked. Moreover, the redoubts did not provide all-round protection and an Austrian observer noted that only Turks would throw up such poor earthworks. Charles's belief that Napoleon would cross north of Lobau seemed to be confirmed on 2 July, when he received news that French forces began to cross the river there. The Austrian commander thought that the battle scenario he had prepared for – a repetition of the battle fought at the end of May – was about to materialise, so he promptly moved his entire force to face the enemy. However, it soon became obvious that the French force was only a small detachment, sent forward to secure a bridgehead.


title: Battle of Wagram

text: On 3 July, Archduke Charles finally decided not to fight the enemy near the Danube and retreated to the higher ground overlooking the Marchfeld. This was a major decision, as it meant that the earlier plan to man the 16 redoubts next to the Danube and fight the enemy there was abandoned. Instead, Archduke Charles occupied both the Bisamberg heights and the Wagram plateau behind the Russbach river, covering the retreat routes to Bohemia and Moravia respectively, thus occupying a sound strategic position. Although the army was not strong enough to occupy both positions and no earthworks were provided for the new position, it was thought that, given that the two heights were placed at an angle to one another, any enemy force attacking would find itself placed between two pincers. There was perhaps further justification for this choice on a tactical level: the broken and wooded terrain in the immediate proximity of the Danube was adapted to fighting in open order formations, which were insufficiently mastered by his men, and at which the French were adept. This was, without a doubt, one of the bitter lessons that the Austrians learned at Aspern and Essling. But above all, the cautious Archduke Charles was unwilling to take the risk of committing his forces in such an advanced position, knowing that he would have a hard time extricating them, should retreat have become necessary. He also planned not to face the enemy on the flat plains of the Marchfeld, an ideal cavalry terrain, where the numerically superior French horse would quickly gain the upper hand. The two influential staff officers, Wimpffen and Grünne, had been actively advocating for this position for weeks and this time Charles finally acquiesced to their point of view.


title: Battle of Wagram

text: Intelligence received on 4 July informed the Archduke that the French had weakened their position at Pressburg, a clear sign that the enemy would launch its operations very soon. At 07:00 on 4 July, Charles wrote to his brother, Archduke John of Austria, whose secondary army was stationed near Pressburg. Charles informed John that the battle was imminent and that it "will decide the fate of our dynasty", ordering him to draw closer to the main army by marching to Marchegg, adding that John should leave behind "all baggage and impedimenta". As chance would have it, heavy thunderstorms delayed delivery of the message, which only got to Archduke John 23 hours later.


title: Battle of Wagram

text: Archduke Charles did not seriously consider the possibility that the French could cross elsewhere than north of Lobau island until late on 4 July. When he finally accounted for this scenario, Charles remained faithful to his earlier plan not to move his forces towards the river. Instead, he planned to allow the enemy to move into the Marchfeld, leaving there only the Advance Guard and VI Korps, with orders to delay their deployment, cause disorder and casualties, while gradually moving back. Meanwhile, he was planning to maintain his main body on the naturally strong position on the Wagram plateau, with the rest of his forces further west on the Bisamberg heights, the two positions that Wimpffen and Grünne had favoured all along. Should the French have attempted to attack the forces on the Wagram plateau, the forces present there were expected to resist long enough to allow Charles to fall on the enemy's flank with the forces placed the Bisamberg heights. Conversely, should the enemy have attacked the forces on the Bisamberg heights, the main force on the Wagram plateau would have attacked the enemy's flank. The plan was good enough, but had two major flaws. Firstly, it failed to account for the slowness of the Austrian staff work, which impaired coordination between these forces. Secondly, it left the Advance Guard and VI Corps with an ambiguous objective: if Charles wanted protracted resistance, then these forces were too weak to accomplish such a task; however, if the objective was only brief resistance, then they were too numerous and thus needlessly exposed.


title: Battle of Wagram

text: Meanwhile, the French were getting ready to cross, according to detailed crossing plans drawn in advance by the Chief of Staff of the "Grande Armée", "Maréchal" Berthier. Napoleon was aware that the Austrians had thrown earthworks between Aspern and Groß-Enzersdorf and planned to cross southeast of these positions and then outflank the enemy fortified line. This meant, however, that his forces had a much longer march before making contact with the enemy. On 4 July, by nightfall, under the cover of a violent thunderstorm that impeded any Austrian observation, Napoleon gave the order for the commencement of the crossing operations.


title: Battle of Wagram

text: One French thrust was directed at occupying the strategic Hansel-Grund salient, east of Lobau island, which a brigade under Conroux secured towards 22:00. This allowed the French to deploy three pivoting bridges, which had been prepared in advance and on which other elements of Oudinot's II Corps began to cross. Meanwhile, further north, Colonel Sainte-Croix, "aide-de-camp" to "Maréchal" Masséna had 1,500 men of IV Corps embarked on landing craft and crossed the river, without meeting any opposition. Sainte-Croix's "pontonniers" then started work and, making good use of the current, managed to bridge the arm of the Danube in no more than five minutes, using another pivoting bridge. This allowed Masséna's divisions to begin crossing, while the division commanded by Legrand, already on the northern bank since 2 July, made a feint towards Aspern and Essling, in a bid to divert Austrian attention from the actual crossing. Several other bridges were finalised towards 02:00, allowing the bulk of II and III Corps, with their respective artillery, cavalry and equipment trains to cross to the northern bank. Napoleon ordered the "pontonniers" to build three additional bridges and work continued well after dawn on 5 July, after the bulk of the "Grande Armée" had already crossed the river. The battle had begun.


title: Battle of Wagram

text: As the French were crossing east of Lobau island, the only significant Austrian force in the immediate vicinity was Armand von Nordmann's Advance Guard, which had been left in the sector with orders to delay the enemy advance. Nordmann's men were faced with a massive artillery barrage from French batteries on Lobau island and, with increasing numbers of enemy battalions coming up, Nordmann had no option but to turn north, leaving behind detachments at Sachsengang castle and Gross-Enzersdorf. With most of his troops available by now, Oudinot and his II Corps approached Sachsengang castle and came up against its defenders: two Austrian battalions and a few small-calibre cannon. The French opted against storming the position and instead brought forward their howitzers, in a bid to shell the defenders into submission. Austrian resistance was brief, with the garrison surrendering towards 08:00. Further north, Masséna directed his divisions straight to the strategic village of Gross-Enzersdorf, where the rest of Nordmann's rearguard (two battalions from the "Bellegarde" regiment) lay. The village itself constituted a sturdy defensive position and Napoleon himself came forward to inspect it, noticing that it was strong enough to potentially delay the deployment of IV Corps onto the Marchfeld plain beyond. The Emperor thus ordered his heavy batteries on Lobau island, including 22 heavy 16-pounders, 14 mortars and 10 howitzers, to bombard the village. In total, some one thousand shells were fired on Gross-Enzersdorf, with the village quickly becoming engulfed in flames. The commander of Austrian VI Korps, "Feldmarshalleutnant" Klenau, whose force was in the vicinity, also with orders to delay the French advance, tried to relieve the defenders, but they were successfully checked by Jacob François Marulaz's French cavalry from IV Corps. With the defenders of the village now cut off and defending what was becoming a burning inferno, Colonel Sainte-Croix assumed command of the 46th Line regiment and stormed the position, taking some 400 prisoners. Further west, the division commanded by Boudet moved against the village of Essling, which fell to the French without much resistance. By 10:00, Napoleon was pleased to notice that the bridgehead had been completely secured and that all enemy attempts to destroy the bridges had failed. Indeed, all Austrian attempts to frustrate the French crossing by using the tactics that worked so well during the Battle of Aspern-Essling – sending barges or trees downstream to ram the bridges – failed utterly on 5 July, because the French flotilla was in full control of the river. This allowed the bulk of Napoleon's army to cross to the northern bank of the Danube at great speed and in perfect safety.


title: Battle of Wagram

text: Archduke Charles was by now well aware of Napoleon's intentions but remained committed to his plan not to fight the battle on the flat Marchfeld plain, where the superior French cavalry would have given Napoleon a clear edge. Thus, Charles did nothing to support his two forward units and watched as Nordmann gradually withdrew north, towards the Russbach line and Klenau withdrew northwest, towards Breintlee. Meanwhile, Napoleon was free to advance north, into the Marchfeld plain, where he would have enough room to deploy his forces. The French advanced in battalion columns, with their front line formed by the Corps of Masséna on the left, Oudinot in the centre and Davout on the right, and the respective Corps cavalry screening the flanks. By noon, the French had advanced into the Marchfeld, a move which so far suited both commanders.


title: Battle of Wagram

text: As the French were successfully moving forward, the Austrian Advance Guard, under "Feldmareschalleutnant" Nordmann, supported by "Feldmareschalleutnant" Klenau's VI Korps, in all 25,000 infantrymen, were gradually withdrawing northwards. The Austrian infantry were formed in masses, a formation that had proved very efficient in fending off cavalry, but whose compact ranks made it extremely vulnerable to artillery fire. Casualties began to mount at an alarming rate and Nordmann's infantry, initially 12,000 men strong, was particularly exposed to artillery fire during its retreat towards Grosshofen. Additionally, towards 13:00, Nordmann became extremely concerned that the numerous French cavalry, might cut him off from the rest of the army. Seeing the dangerous situation of his Advance Guard, Archduke Charles ordered Liechtenstein to the rescue of these infantrymen with five cavalry regiments. Liechtenstein moved swiftly towards the east with his squadrons, arriving in the vicinity of Glinzendorf, but then remained passive, while the French, who now had a numerous combined-arms presence there, were able to continue their advance unmolested. The first serious Austrian attempt to slow down the French onslaught came towards 15:00, when Liechtenstein and Nordmann tried to organise a joint operation, but they gave up quite early on, realising that they were opposed by a very powerful force of several infantry divisions and three cavalry divisions from "Maréchal" Davout's III French Corps. The Austrians pulled back, leaving Davout free to position his men between Glinzendorf and Raasdorf, thus drawing closer to the II Corps.


title: Battle of Wagram

text: Further west, "Maréchal" Bernadotte's IX Corps had been steadily advancing, with the French II Corps on their right, but began to meet steady resistance, when troops from Nordmann's Corps decided to make a stand. These men were from Riese's brigade, soon reinforced by the 13th Wallachian-Illyrian "Grenzer" and Infantry Regiment 46 "Chasteler". Bernadotte sent forward the two battalions of the 5th Light regiment, which successfully pushed back the opposition, allowing the rest of his Corps to continue its advance towards the village of Aderklaa, near which they had to stop, towards 15:30, as they met enemy cavalry. Towards 17:00, in an attempt to secure the vital position at Aderklaa, the Austrians launched a cavalry attack with the brigade of French "émigré" Roussel d'Hurbal. This heavy cavalry brigade, around 1,000 sabres strong, deployed on two lines, with the 3rd "Herzog Albert" Cuirassiers on the left and the 2nd "Erzherzog Franz" Cuirassiers on the right. D'Hurbal was suddenly charged by the 400 cavalrymen from the Saxon "Prinz Klemens Chevaulegers" regiment from Bernadotte's Corps, who had recklessly moved forward unsupported. D'Hurbal's cuirassiers stood to receive the charge and repulsed them by firing a pistol volley from 30 meters. This practice that was highly unusual for the cavalry tactics of the time but in this case it worked perfectly, with the Saxon chevaulegers sent fleeing. The Saxons then brought up the bulk of their cavalry, in echelon formation, with the right leading. D'Hurbal again chose to meet them with a pistol volley but this time the Saxons managed to maintain the impetus of their charge and crashed into the Austrian cuirassiers. Amongst the Saxon cavalry was a single squadron of the "Herzog Albrecht Chevaulegers" regiment, which shared the same Regimental Proprietor with the Austrian "Herzog Albert" cuirassiers and these units fought in a generalized melee that involved the entire cavalry present. After a few minutes, d'Hurbal's Austrians were beaten back and pursued, until they were rescued by Lederer's cuirassier brigade. After this cavalry action, Prince Liechtenstein decided that he had lost too many men to no avail and consequently pulled the bulk of his forces back to safety, behind the Wagram-Gerasdorf line, leaving five cavalry regiments with the IV Korps at Markgrafneusiedl.


title: Battle of Wagram

text: Meanwhile, Nordmann's slow retreat allowed Klenau's VI Austrian Korps, which had also been placed in an advanced position, to make a skillful fighting retreat westwards, taking few losses. In sharp contrast, Nordmann's Advance Guard suffered horrendous losses, with its initial 12,000 infantry reduced to little more than 6,000 soldiers capable of further action. This unusually high casualty rate resulted from Nordmann having been positioned in a perilous location and having been maintained there for too long, to little purpose. Additionally, Nordmann had benefitted from little protection from the cavalry present in that sector. After a well-led and determined staged retreat, Nordmann managed to extricate his battered troops, reaching the relative safety of the town of Markgrafneusiedl. The Advance Guard continued to constitute a viable fighting force and they were thus integrated in the IV Korps, guarding the Austrian left wing. The Austrian army was now deployed on a very wide ark-shaped frontage, long, including Klenau's VI Korps on the far right, then Kollowrat's III Korps on the right-centre, Hohenzollern's II Korps and Bellegarde's I Korps behind the Russbach line in central position, while Rosenberg's IV Korps covered the left. Liechtenstein's Grenadier Reserve divisions were placed in second line, with the Cavalry Reserve in a central position next to the village of Wagram.


title: Battle of Wagram

text: Opposite to the Austrians lay the French Army, which managed to fully deploy towards 18:00. From left to right, the French army included: Masséna's IV Corps, covering a wide area between the Danube and Süssenbrunn, the lead elements of Bernadotte's XI Corps (Dupas's division) near Aderklaa, Viceroy Eugène's "Army of Italy" in the centre, while Oudinot's II Corps was deployed opposite to Baumersdorf and Davout's III Corps continued the French line eastwards, beyond Glinzendorf. The rest of the French and Allied troops, including the Imperial Guard and "Maréchal" Bessières's Cavalry Reserve, were in second line. Napoleon had a sound strategic position, as he was holding the central position and had a much shorter line than his opponent.


title: Battle of Wagram

text: After the successful crossing of the Danube and deployment of his army on the Marchfeld plain, Napoleon achieved his primary goal for the day. Nevertheless, towards 18:00, either because he was dissatisfied with the result of the first engagements or because he was fearing that the enemy might retreat under the cover of darkness, the Emperor began issuing orders for an immediate attack. Never a man to lose time, Napoleon probably noted that the sun was still high on the sky, that the Austrian right wing was placed noticeably far away from the main body, and that there was still no sign of the arrival of Archduke John's army from the east. This attack was also meant to probe the strength and resolution of the enemy, as the Emperor did not know exactly what forces lay before him. The attack was to take place against the Russbach line on a wide front, between Wagram and Markgrafneusiedl, with Bernadotte, Eugène, Oudinot and Davout all ordered forward. Nevertheless, the French troops were all very tired and the most difficult tasks were assigned to some of the weakest troops available, namely elements of the Corps of Bernadotte and Oudinot. Additionally, with the Emperor ordering an immediate attack, the General Staff failed to transmit the orders to the respective commanders in due time, which resulted in a failure to launch synchronized actions.


title: Battle of Wagram

text: An artillery bombardment, between 19:00 and 19:30 opened up the French attack, with Oudinot launching a part of his II Corps against the Austrian II Korps under Prince Hozenzollern. The Austrian defenders were prepared for the attack: Hohenzollern had deployed his men in two lines, with a heavy skirmisher screen and was occupying a naturally strong position, which had been reinforced with earthworks. The Austrian Korps had also deployed its powerful artillery of 68 pieces. Nevertheless, the French crossed the Russbach stream, spearheaded by Frère's division, which managed to reach the outskirts of the small village of Baumersdorf. This village, consisting of no more than 30 wooden houses and a bridge, soon caught fire from the French artillery bombardment, but the Austrian defenders from Hardegg's brigade (8th "Jäger" regiment and a battalion of Volunteers from the "Erzherzog Karl Legion") stood their ground, despite the flames. Unable to storm the position with Frère's division, Oudinot launched a flanking attack to the right of the village, with some of his best troops: the 57th Line regiment (styled "the Terrible") and the 10th Light regiment, both from Grandjean's division. The 57th Line valiantly assaulted the village from the east and occupied its first houses, where they had to stop. Meanwhile, the 10th Light crossed the Russbach downstream and, after passing through the boggy terrain below the escarpment, began to make its way up the slope. As the 10th Light was coming up towards the village, they were at first greeted with intense artillery fire and then Buresch's brigade released some heavy musketry upon them. This disordered the ranks of the French regiment, which began to waver and the last straw came when they saw Prince Hohenzollern personally leading the 500 cavalrymen from the "Vincent Chevaulegers" regiment against them: the 10th Light panicked and fled, taking the 57th Line with them. After a disorderly retreat, the two regiments stopped and reformed when they met the steady ranks of the Imperial Guard, towards Raasdorf. By now, it was past 20:00, night was falling and Oudinot had been repulsed with significant losses.


title: Battle of Wagram

text: While Oudinot was engaged with Hohenzollern at Baumersdorf, to the west, "Général de Division" Jacques MacDonald, commander of the V Corps of the "Army of Italy" launched his men in an assault on the Wagram plateau. With the village of Baumersdorf in flames and a gentle breeze blowing from the east, the advance of the French troops was masked by heavy smoke. Dupas's division, temporarily attached to the "Army of Italy", spearheaded this attack and, as chance would have it, happened to get between the Austrian 1st and II Korps and was thus free to advance unmolested on Deutsch-Wagram from the east. Attacking Dedovich's division at Deutsch-Wagram, Dupas's small Franco-Saxon division was soon supported by Lamarque's division, personally led by MacDonald, with the divisions of Seras, Durutte and Sahuc, all from Paul Grenier's VI Corps, also coming up in support. Seeing the French advance, the Austrian artillerymen panicked and abandoned their guns, with the infantry regiments 35 and 47 ("Vogelsang") also retreating in some disorder. "General der Kavallerie" Bellegarde intervened in person, maneuvering to refuse his flank to the enemy, with the French advance also faltering, due to heavy smoke. With visibility reduced, the French mistook the white uniforms of their Saxon allies from the Schützen and Grenadier battalions, believing them to be Austrians and promptly firing at them, which triggered a precipitated retreat of these men. With Archduke Charles now personally present to reestablish order, the morale of the Austrians soared and a vigorous joint attack by infantry regiment 42 ("Erbach"), joined by Hohenzollern's "Vincent Chevaulegers" and "Hessen-Homburg" Hussars repulsed the French attackers, pushing them beyond the Russbach and to their initial positions. Bellegarde's good maneuver and Archduke Charles's inspired intervention ensured a totally successful counterattack, and avoided what could have developed into a dangerous situation for the Austrian army. Opposite to them, both the Saxons, who had suffered high casualties, and the French troops were retreating in complete disorder and halted only near Raasdorf.


title: Battle of Wagram

text: To the west, "Maréchal" Bernadotte, in command of the Saxon IX Corps, was preparing his own assault, planning to attack the Austrians at Deutsch-Wagram from the west. This attack was delayed, as Bernadotte had to wait for the arrival of Zezschwitz's division, but at around 21:00 the Saxons moved towards the village. As Lecoq's Saxon brigade approached the position, they were instantly met with sustained musketry fire from the Austrian defenders, two battalions of infantry regiment 17 ("Reuss-Plauen") and the 2nd "Jäger" regiment, but the Saxons pushed on and entered the village. Once they reached the vicinity of the village church, the Saxons were steadily met by the third battalion of infantry regiment 17 and the attack at once broke down, with the attackers forced to take shelter in the buildings nearby. Moments later, Zeschau's Saxon brigade, with Prince Maximilian's regiment attached to it, came in support, but these troops had been much disordered when crossing the Russbach, and upon entering the smoke filled streets of the village, they too lost impetus. With visibility much reduced by smoke, the situation at Deutsch-Wagram soon turned into chaos as all the troops inside spoke German and all, except the Austrian "Jägers", wore white uniforms. There were thus several instances in which Saxon troops fired at each other and their situation took a turn for the worse towards 22:30, when "Generalmajor" Hartizsch brought fresh Saxon troops against the position. Hartizsch was not informed that friendly troops were already in the village and, as he was coming up for the attack, he saw a large number of white-coats moving out of the position. The commander at once ordered his men to fire and minutes of friendly fire and hand-to-hand combat ensued before it became obvious that these men were actually Saxons too. This fortuitous event had a significant impact on the attack, as the Saxons in the village now thought themselves surrounded and at once broke and retreated in disorder. The Saxon troops of the IX Corps were now completely demoralised and any attempts to rally and reform them at Aderklaa towards 23:00 failed.


title: Battle of Wagram

text: A final French attack was launched by Davout's III Corps, on the French right. Just like Bernadotte's, this action began later than expected, towards 21:00, with Davout's men tired after a day of marching and fighting. The French objective in this sector was to attack the naturally strong position at Markgrafneusiedl, which had been reinforced with earthworks and was defended by the rested troops of "Feldmarschalleutnant" Rosenberg of the Austrian IV Army Korps. After a short artillery bombardment, Davout sent the divisions of Friant and Morand across the Russbach stream, in a flanking attack from the east, while his other two divisions, under Gudin and Puthod were ordered to attack frontally, through the village of Grosshofen. Davout also sent a part of his cavalry to open the way for the infantry attack but the Austrian cavalry under Nostitz promptly repulsed the French horse. Realising the futility of his action, Davout called off his infantry attack towards 22:00, leaving only his artillery to exchange fire with the Austrian gunners. Davout's initiative to call off his attack early on triggered subsequent, perhaps unwarranted, criticism from Napoleon.


title: Battle of Wagram

text: With the fighting fading out completely towards 23:00, the two commanders were at their respective headquarters, knowing that the following day would be decisive for the outcome of the battle. Meanwhile, with an extremely cold night settling in, soldiers from both armies lit fires to warm up, while they were resting and consuming their modest rations.


title: Battle of Wagram

text: Late that night, the French Corps commanders reunited at the Emperor's headquarters at Raasdorf; only Bernadotte was absent, as he was still struggling to rally his routed infantry at Aderklaa. Napoleon knew that he had sustained high losses during the evening attacks and that he had failed in his attempt at a quick breakthrough. As many as 11,000 French and Allies were out of action, including Paul Grenier, commander of VI Corps, who had suffered a shattered hand and was out of action for the next day. Despite these setbacks, the Emperor had managed to fix the enemy forces and was now certain that Archduke Charles was ready to give battle on his current positions. For the second day of battle, Napoleon planned a main attack against the enemy left, which was to be conducted by the powerful III Corps under "Maréchal" Davout, who was ordered to attack the enemy on the plateau behind the Russbach stream, storm the strategic village of Markgrafneusiedl and then roll up the enemy flank. Such an action, if successful, would have compromised the position of the other Austrian Korps on the Wagram plateau and would have forced them back northwestwards, away from any reinforcements they might have expected to receive from Pressburg. Napoleon also planned for his II and IX Corps, as well as the "Army of Italy" to launch secondary attacks, in order to prevent the Austrians from sending reinforcements to their left. In order to shorten and reinforce his battle line, the Emperor also ordered that most of the IV Corps move closer to Aderklaa, with this Corps set to take its new positions towards 02:00 that night. This meant that only Boudet's division was left at Aspern, with orders to defend the lines of communication lines with the military base on Lobau island. The Imperial Guard, Cavalry Reserve and the reinforcements that Napoleon was expecting were to form the battle reserve of the army.


title: Battle of Wagram

text: After the conference, Napoleon asked Davout to stay on and the two spent a long time planning Davout's difficult and complex attack on the fortified position at Markgrafneusiedl, an action which the Emperor saw as decisive for the battle to come. Napoleon was expecting reinforcements: the French XI Corps under Marmont, the divisions of Broussier and Pacthod from the "Army of Italy", as well as the Bavarian division under Wrede, which were approaching the battlefield that night. These reinforcements placed the French and Allied forces at 140,500 infantry, 28,000 cavalry and 488 guns, with an additional 8,500 men and 129 guns left behind as garrison on Lobau island.


title: Battle of Wagram

text: Archduke Charles of Austria was also planning the next day of battle, at his headquarters in Deutsch-Wagram. Charles was exhausted and had been lightly wounded when he took personal command of a regiment during the critical moments of the battle, but overall he was probably satisfied with the result of the first day of battle. Despite heavy losses (some 6,000 infantrymen) in von Nordmann's Advance Guard, the other formations of the Austrian army were virtually intact. Charles probably noted that, while the enemy managed to deploy on the Marchfeld plain with a surprising speed, all was going according to plan, as it had always been his intention to face them here. Additionally, with the exception of Nordmann's Advance Guard, losses had been relatively moderate and overall the army had fought extremely well. He reckoned that his best option was to take the initiative and, as he later wrote: "seize the only means which could give any prospect of success against the superior enemy, namely to fall on them by surprise on all sides as day broke". Orders for an all-out attack at 04:00 were issued at around midnight and Charles's intention was to take advantage of his much longer battle line (around 18 kilometers long, to the French 10 kilometers long line) and take the enemy in a double envelopment. To that effect, VI Korps was ordered to advance on Aspern, with the fresh troops of III Korps on their left, moving through Leopoldau towards Breitenlee, and the Grenadier Reserve was to move through Süssenbrunn. These three Corps were also ordered to keep in line with each other, with the Cavalry Reserve ordered to take position between Süssenbrunn and Aderklaa. The Austrian 1st Korps was to move out of Wagram and advance along the Russbach, with II Korps ordered to remain in place, in order to avoid congestion, and simply provide artillery support. On the Austrian left, IV Korps, with the Advance Guard now attached to it, was to move against the French III Corps, and it was expected that Archduke John's "Army of Inner Austria" would arrive from Pressburg in time to support this attack. There would be no proper battle reserve, with the only remaining formation, Prince Reuss's small V Korps left out of the action, as a strategic reserve, with the objective of observing the Danube and protecting the vital routes to Bohemia and Moravia, should retreat become necessary.

text: Coordination between the Korps' movements was vital for the success of this plan, yet this was something that the Austrian army command and control system had repeatedly failed to achieve during past conflicts. As a result, the two Corps that were farthest from headquarters, VI and III Korps, only received their orders towards 03:00, two hours late. Given the distance that these troops had to march in order to make contact with the enemy, it was clear to the two Korps commanders that they would be unable to attack at 4:00 as ordered. Archduke Charles was also expecting the arrival of reinforcements, 13,000 men of the "Army of Inner Austria" led by his brother, Archduke John, whose role was crucial in supporting the attack against the French right. While Charles thought that his brother should arrive on the field of battle at any moment, the latter actually only began his march of march from Pressburg at around 01:00 that night. Without Archduke John's men, the Austrians could muster only 113,500 infantry, 14,600 cavalry and 414 guns for the second day of battle.


title: Battle of Wagram

text: Positioned on the left of the Austrian army, in and around the strategic village of Markgrafneusiedl, "Feldmarschalleutnant" Prince Rosenberg-Orsini was in command of the 18,140 men and 60 cannons of the IV Korps. In addition, attached to his force was the much-battered Advance Guard, under "Feldmarschalleutnant" Nordmann, reduced to around 6,000 infantrymen and some cavalry support, as well as the 3,120 cavalrymen from "Feldmarschalleutnant" Nostitz's division. Receiving his orders in due time, Rosenberg began to organise his attack, forming the IV Korps into three large columns, preceded by an advance guard. The first column was formed by Hessen-Homburg's brigade, 6 battalions strong, which was directed towards the village of Grosshofen. The second column was 16 battalions strong (12 regular and four "Landwehr" battalions) and included the brigades of Swinburn and Weiss, with the orders to move on to Glinzendorf. The second column was preceded by an advance guard under "Feldmarschalleutnant" Radetzky, 10 battalions and 10 cavalry squadrons strong. The third column, under Nostitz, was 30 squadrons strong and was directed to outflank the French, towards Leopoldsdorf. Setting these troops in motion towards 4:00, just as his orders stated, Rosenberg instructed his commanders to maintain absolute silence among the rank and file as they advanced but, despite this, the troops moved forward in some disorder and with a lot of noise.


title: Battle of Wagram

text: Opposite to them lay the III Corps, perhaps the finest of the French army, under the command of "Maréchal" Davout. Davout was in command of 31,600 infantry (divisions of Morand, Friant, Gudin and Puthod), 6,200 cavalry (divisions of Grouchy, Pully and Montbrun) and 120 cannon. Davout was unaware that the Austrians were moving to attack him, but he was himself preparing his attack, and thus his troops were ready for action. Puthod's leading elements, one regiment strong, were at Grosshofen, with Gudin positioned between this village and Glinzendorf, which was held by Friant, supported by Morand. The entire cavalry was positioned to protect the right flank of the Corps. To the French surprise, towards 05:00, the Austrians attacked, with Radetzky's leading elements pushing the French outposts out of Grosshofen, and then attacking Glinzendorf. Davout immediately ordered a counterattack on Grosshofen, with Puthod attacking frontally and Gudin from the flank, and made sure that the defenders of Glinzendorf steadfastly hold their ground, while releasing heavy musketry upon the slowly advancing enemy columns. Grouchy's dragoons rode to face the enemy cavalry column, while Montbrun sent a part of his light cavalry division towards Ober Sieberbrunn, in a bid to outflank the Austrians. The sound of the cannon coming from Davout's sector interrupted Napoleon's breakfast, with the Emperor thinking that Archduke John must have arrived on the field of battle with his forces. The threat of Archduke John's arrival was overestimated, since French intelligence inaccurately placed the strength of this army at 30,000 men, instead of its actual 13,000 men. Napoleon immediately ordered Nansouty's and Arrighi's heavy cavalry divisions from the Cavalry Reserve to that sector, followed by the Imperial Guard. Nansouty's horse artillery was the first to arrive and deployed on the right flank of the advancing Austrians, opening enfilade fire.


title: Battle of Wagram

text: Meanwhile, Archduke Charles was observing the entire operation. With Archduke John's reinforcements failing to materialise from the east and no sign of the III and VI Korps approaching from the west to take their intended positions, Charles realised that the unsupported Rosenberg was now too exposed and in an increasingly dangerous position. Charles thus ordered Rosenberg to fall back to his initial position at Markgrafneusiedl and assume a defensive posture there. This was no easy task and it took all the determination and skill of "Feldmarschalleutnant" Radetzky in coordinating a combined-arms operation to slow down the French onslaught, while the rest of Rosenberg's troops retreated. By 06:00, Rosenberg was finally back to his initial positions, but his two-hour action had cost him no less than 1,100 casualties.


title: Battle of Wagram

text: Napoleon, who was by now present alongside Davout, reconnoitered the situation and, seeing that Archduke John's army was nowhere near the battlefield, ordered the reserves back to Raasdorf, leaving only Arrighi's cuirassiers and a battery of 12-pounders with III Corps. The Emperor reconfirmed that he wanted Davout to take Markgrafneusiedl, but, instead of a massive frontal attack, he instructed the Marshal to launch a part of his men frontally against the position and a part in an enveloping move from the east, in order to take advantage of the gentle slope there. These new orders meant that Davout could not start his attack right away, as he needed to send a part of his troops east, where he had to bridge the Russbach stream, in order to allow his artillery to cross. Napoleon then issued orders to Oudinot and Eugène, instructing them to support Davout by pinning down the Austrian forces on the Russbach, once the IIIrd Corps began its attack.


title: Battle of Wagram

text: While Rosenberg was attacking on the left, "General der Kavallerie" Bellegarde, commander of the Austrian 1st Korps, also set his men in motion in time, just as his orders stated. He had begun his manoeuvre just after 03:00, moving south, out of his position along the Russbach line and at Deutsch-Wagram, Bellegarde formed a vanguard of three battalions and three squadrons, under the command of "General-Major" Stutterheim, which he sent towards Aderklaa. A strategic village that was surrounded by an earthwork, Aderklaa offered a strong defensive position and Bellegarde was naturally expecting to encounter stiff resistance from the enemy defending the village. He was much surprised to receive reports that the village was completely undefended and, after making sure that it was not a trap, Bellegarde immediately ordered his vanguard to occupy it. The 1st Korps commander then brought an additional force of 12 battalions of "Feldmarshalleutnant" Fresnel's division, which he deployed in two lines, behind the position and formed the rest of his Corps in a line between Aderklaa and Deutsch-Wagram. Liechtenstein's cavalry duly came up in support, taking a wide position behind 1st Korps, between Deutsch-Wagram and Süssenbrunn, but Bellegarde chose not move beyond Aderklaa. An immediate Austrian attack would have posed a serious threat to the stability of the French left wing, but Bellegarde had orders which stated that he needed to wait for the Grenadier Reserve to arrive and align itself on his right.


title: Battle of Wagram

text: The task of defending Aderklaa belonged to "Maréchal" Bernadotte, commander of the Saxon IX Corps. However, Bernadotte's largely inexperienced infantry had suffered greatly during the evening attacks the day before and many units had routed, retreating beyond Aderklaa. With his infantry reduced to some 6,000 men, the commander had difficulties rallying a part of his troop but he could still count on two reasonably valid Saxon divisions. As he would later explain, Bernadotte believed himself in an exposed position and thus took the initiative of abandoning Aderklaa during the night, retreating almost 1 kilometer to the southeast of the village, in a bid to draw closer to the rest of the army. Withdrawing without permission and without notifying Napoleon of his action, Bernadotte irresponsibly compromised the entire French position on the left. Towards 04:00, seeing that the enemy had taken position in and around the village, Bernadotte assembled his artillery in a battery of 26 pieces, which began to bombard Aderklaa, but the Austrian heavy artillery at Deutsch-Wagram responded by releasing a devastating counter-battery fire, which knocked out 15 Saxon pieces during the following three hours.


title: Battle of Wagram

text: Meanwhile, an injured Masséna, leading his IV Corps from a conspicuous white phaeton, was also executing his orders and approaching the sector with three of his infantry divisions and his cavalry. In compliance with Napoleon's orders, Masséna's fourth infantry division, under General Boudet, had been left far to the south, defending the village of Aspern. The manoeuvre of IV Corps was hampered by the arrival of the leading battalions of the d'Aspré's division from the Austrian Grenadier Reserve, which delayed Masséna's rearguard division, under General Legrand. Arriving with his other two divisions in the vicinity of Aderklaa towards 07:30, Masséna was spotted by Napoleon, who got into the Marshal's phaeton to consult with him about the situation they were facing and, after a brief discussion, the Emperor ordered the recapture of Aderklaa. Masséna instructed General Carra Saint-Cyr to storm Aderklaa with his division and, seeing that the General delayed his action, trying to find a weak spot of the solid position, the Marshal hurried him forward for an immediate attack. The assault was led by the 24th Light and 4th Line regiments, which were followed by the excellent Hessian Guard brigade. Further east, the still combat-worthy Saxon Corps, including the Franco-Saxon division of General Dupas also moved forward, in a bid to launch a supporting attack between Aderklaa and Deutsch-Wagram. The 24th Light and 4th Line successfully drove back the two Austrian battalions positioned before the village, which broke and caused some disorder in the Austrian first line. The French impetuously moved into Aderklaa and then tried to launch a pursuit beyond this position, but, as soon as they moved out of the village, they were met with sustained fire from Bellegarde's second infantry line. The two regiments withdrew to Aderklaa, where they were reinforced by the Hessian Guard brigade and ordered to hold the position. Not far away from this position, the attack of the Saxons also came to a grinding halt and these men were driven back, exposing the flank of the French troops occupying Aderklaa. At this moment, the Austrians enjoyed a substantial, albeit temporary numerical advantage in this sector, 44,000 men to the French 35,000. This was thus the right time for a general attack, but the Austrian military doctrine discouraged commanders from taking too much initiative, and Bellegarde chose to stick to his orders and wait for III Korps, whose leading elements were only just coming up, in line with the Grenadiers.


title: Battle of Wagram

text: Archduke Charles noticed the development on his right, from his observation post at Baumersdorf and promptly rode to Bellegarde with new orders. Charles then personally organised an attack on Aderklaa, with the combined elements of infantry regiment 42 ("Erbach") of the 1st Korps and Grenadier battalions "Scovaud", "Jambline" and "Brzeczinski" from the Reserve Korps. The "Klenau Chevaulegers" from Liechtenstein's cavalry also charged in support of the infantry. This powerful attack drove Carra Saint-Cyr's defenders out of Aderklaa and the cavalry attack resulted in them joining the panic-stricken Saxons in a disorderly retreat. Masséna's cavalry, under Lasalle and Marulaz promptly stepped in to protect the retreating infantry, driving off the Austrian horse and then charging the artillery that the Austrians were preparing to deploy in front of Aderklaa. The Austrian gunners abandoned their pieces and fled, but Liechtenstein committed additional cavalry, which at once repulsed the French horsemen. Meanwhile, Masséna was preparing to retake Aderklaa with the division of Molitor, spearheaded by Leguay's brigade and the 67th Line regiment. These men soon found their advance barred by a crowd of retreating Saxons, with Masséna forced to order his men to fire at them, in order to clear the way. Molitor decidedly advanced towards his objective, despite the enemy fire and cavalry threatening his flanks and, after some bitter fighting, managed to retake the village towards 09:45.


title: Battle of Wagram

text: Nevertheless, the Austrians had sufficient fresh troops in this sector and they soon launched fresh attacks, with elements of 1st Korps and the Grenadier Reserve. Despite having taken heavy casualties during his attack, Molitor resolutely defended the position and it took the numerous Austrians in the sector two full hours before they were able to finally expel him. As for the Saxons and great many Frenchmen, they continued their retreat, with the first fugitives and Bernadotte approaching Raasdorf, were they suddenly met Napoleon in person. For the Emperor, the sight of Bernadotte riding at the head of the disorderly mob and making no apparent attempt to rally his men, was the last straw. After a brief exchange of words, Napoleon sacked the Marshal, adding "A bungler like you is no good to me." The Saxon infantry was by then completely disorganised and it could play no further role in the battle, with only the cavalry and ten cannon still combat-worthy.


title: Battle of Wagram

text: In application of Archduke Charles's plan to take the enemy in a double envelopment, "Feldmarshalleutnant" Klenau, commanding VI Korps, and "Feldzeugmeister" Kollowrat, commanding III Korps, moved forward towards the French left. Both commanders had received their orders very late and both had a long distance to cover before they could reach their assigned positions. They did their best to comply but, given the difficulties of a long night march, their leading elements could only manage to arrive on the Austrian right between 07:30 and 08:00, three hours later than Charles had planned.


title: Battle of Wagram

text: Klenau was the first to make contact with the enemy. His troops left Leopoldau towards 07:30 and subsequently deployed between Breitenlee and Hirschstetten, driving in the enemy outposts in the sector. The only French force present here was the 4th division of the IV Corps, under "Général de Division" Boudet, some 4,600 men, to Klenau's 14,000. At 08:00, Klenau unlimbered his artillery and began to fire at the French, while sending forward Vecsey's brigade from "Feldmarshalleutnant" Vincent's division to take the village of Aspern. Boudet saw this development and sent forward a battery of ten cannon, with orders to open enfilade fire and thus delay the enemy. This proved to be a very uninspired move, as Austrian hussars suddenly came up and captured these guns. The French 56th Line regiment boldly charged the enemy horse and momentarily recaptured the guns, but they lacked horses to carry them back and the intense Austrian cannonade soon compelled these men to retreat and leave behind the artillery. After making a timid attempt to defend Aspern with the 93rd Line, Boudet then chose to retreat towards Essling and Vincent's division occupied Aspern, subsequently launching a determined pursuit. The Austrians soon came in range of the French heavy batteries placed on Lobau island, and the bombardment slowed down their advance, but they still pushed on towards Essling, which Boudet promptly abandoned towards 10:00.


title: Battle of Wagram

text: The French retreated towards the Mühlau salient and to Groß-Enzersdorf, in a bid to protect the vital bridges towards Lobau island. The Austrians then launched a probing attack on the bridgehead but were rapidly repulsed and subsequently contented themselves with bombarding the French supply train, causing some panic among the civilian suppliers. From his current position, Klenau was able to either strike in the undefended rear of the enemy army, some five kilometers away, or to attack the vital bridges towards Lobau island. However, the Austrian commander chose caution; his force was only about 14,000 men strong, a part of which was now in range of the numerous French heavy batteries on Lobau island and his orders provided for his Korps to keep itself abreast with Kollowrat's III Korps. Had Kollowrat moved forward himself, protecting Klenau's left flank, the Austrian VI Korps might have envisaged the continuation of its action, but, as things were, Kollowrat had not yet moved from his position between Süssenbrunn and Breintlee.


title: Battle of Wagram

text: Indeed, further north, Kollowrat had been slow in moving forward with his numerous III Korps. He deployed between the villages of Süssenbrunn and Breintlee and thus threatened the French flank, which was defended only by Legrand's infantry division and some cavalry. Kollowrat finished his positioning manoeuvres only towards 09:30, when his men made contact with Prochaska's Grenadier division of Liechtenstein's Reserve Korps. For lack of orders, Kollowrat did not attempt an attack against the weak French left. In a move which was typical for Austrian tactics at the time, the 60-year-old Austrian commander had been busy securing his own rear, rather than thinking of any offensive action. He had cautiously left behind an entire brigade on the Bissamberg heights, facing Vienna, and detailed a sizable force to garrison Gerasdorf, a village situated in his rear. He also sent a combined-arms force to occupy the village of Breintlee, to the south. Despite his sound tactical position, which allowed him to envelop Masséna's flank or even march towards the undefended Raasdorf, in the rear of the French army, Kollowrat moved forward cautiously, contenting himself with bombarding Masséna's force with two batteries that he had positioned near Breintlee.


title: Battle of Wagram

text: With the situation looking increasingly dangerous for his army, Napoleon reassessed the developments and probably noted that he was holding the central position of an increasingly curved battlefront. He first sent word to Davout to hasten his attack preparations against the Austrian left, but the most urgent matter was to stabilise his own battered left wing. The Emperor did not want to commit his valuable, fresh infantry reserves just yet, so he ordered Masséna to break contact with the enemy and take his IV Corps southwards and attack the Austrian VI Korps. Executing such a manoeuvre required great skill and incurred high risks, as it meant that Masséna's men would have to move in vulnerable march column formations, through a sector with numerous enemy infantry, cavalry and artillery. The departure of these troops also meant that an enormous gap would open up in the French line, which the Emperor ingeniously intended to fill by forming an enormous grand battery, which would check enemy advance in this sector through a sustained artillery barrage. This required time and, with the Austrians from III Korps menacingly moving forward, Napoleon counted on "Maréchal" Bessières's cavalry to allow Masséna to disengage and the grand battery to deploy.


title: Battle of Wagram

text: Towards 11:00, Bessières received his orders, which provided for an immediate attack at the weak point of the enemy line, the seam between Austrian III Korps and the Reserve Korps, where only "Feldmarshalleutnant" Prochaska's thinly spread division was covering the wide position between Süssenbrunn and Aderklaa. With the division of Arrighi sent in support of Davout, far on the right flank and the division of Saint-Sulpice detailed to protect Masséna's IV Corps, Bessières brought forward his only remaining unit, the mighty 1st heavy cavalry division, under the skilled 41-year-old general Nansouty. Napoleon also sent orders for the Guard cavalry to come in support, but his orders seem not to have reached them at all. Circumstances were so dire on the French left that Bessières opted not to wait for the Guard cavalry and sent orders for an immediate charge.


title: Battle of Wagram

text: It seems that Saint-Germain's brigade was left behind in reserve and out of the actual attack, so Bessières took Nansouty's remaining 16 squadrons, some 2,800 men, including Defrance's 1st and 2nd "Carabiniers-à-Cheval" and Doumerc's 2nd and 9th Cuirassiers. The hastily formed squadrons rode forth, but the flat terrain of the Marchfeld provided them with little cover from the devastating fire unleashed upon them by Austrian artillery. The heavy horsemen eventually made contact with the enemy near the village of Süssenbrunn, but found the infantry prepared to receive them and their first charge failed altogether. Rallying the men for a second attempt, with the elite "carabiniers-à-cheval" leading the way, Nansouty pushed through, but many of his troopers were unable to follow, leaving many of the squadrons reduced to just a handful of men. It seemed at first that the charge would do some serious damage, especially when the Frenchmen managed to break and sabre the "Grenz" "Georger" battalion, thus creating a breach between the two Austrian Corps. In the end however, the effects of a cavalry charge against prepared infantry were always set to be limited and the cavalrymen made little further impression on the grenadier battalions, which were by now formed in tight, solid squares. Displaying some great tactical skill, Nansouty wheeled right with his men and fell upon the Austrian artillery line near Aderklaa. Meanwhile, Bessières was busy fetching the Guard cavalry, which was only just beginning to arrive and with which he was intending to launch a second charge. Virtually under Napoleon's eyes, a cannonball brushed Bessières's thigh, unhorsing the Marshal, who violently hit the ground and lost consciousness. While Bessières was being carried away from the battlefield, Nansouty and his "Carabiniers-à-Cheval" managed to capture an Austrian artillery battery but Liechtenstein duly sent his fresh cavalry, the 6th "Rosenberg Chevaulegers" and 4th "Kronprinz Ferdinand" Cuirassiers against them. The Austrians hit the now diminished and tired French cavalry in flank, wounding Defrance and sending his men reeling back to their own lines with heavy casualties. The light cavalry of the Guard, some 2,000 sabres, belatedly launched a brief charge of their own, but they were also repulsed by the prepared enemy. With Bessières presumed dead, Nansouty took command of the entire cavalry, but, not knowing the Emperor's directives, decided to pull his battered troop back. In all, the French cavalry charge had been very costly; for the entire day, Nansouty's division alone lost 1,200 horses killed or wounded and a great number of men out of action. However, it did allow Masséna to successfully disengage and gained time for the deployment of the grand battery.


title: Battle of Wagram

text: Napoleon was aware that the cavalry charge was a stopgap, so, while the heavy cavalry was busy blocking the advance of the Austrian infantry, he ordered General Jacques Lauriston to assemble a massive battery. Its objective was to pound the enemy, stop their advance and force them to abandon their position between Aderklaa and Süssenbrunn. Lauriston's battery was formed of 84 pieces, including the entire 60 pieces of the Imperial Guard artillery park and 24 pieces supplied by the "Army of Italy". The horse artillery of the Guard, six batteries of six-pounders, eight-pounders and heavy 24-pounder howitzers, under the command of Colonel Augustin-Marie d'Aboville, was the first to come into action, towards 11:00. It was followed by the foot artillery of the Guard, four batteries of 12-pounders, under the command of Lieutenant-Colonel Antoine Drouot, and, shortly after, by the pieces from the "Army of Italy". The grand battery was deployed on a single line, covering some 2 kilometers, with the "Army of Italy" cannon facing Liechtenstein's Reserve Korps, while the Guard foot artillery was in the centre, facing Kollowrat's III Korps and the Guard horse artillery extended the line southwards, facing the village of Breintlee, which was in enemy hands. As they unlimbered, the French guns were ordered to open fire at once and the relatively short range—350 to 550 metres—and the flat and sodden ground, which allowed cannonballs to ricochet far, meant that results were almost immediate. Entire files of Austrian infantry and cavalry, sometimes as much as 20 men, were blown away with a single shot and in some cases the French were even able to use short-range case-shot, which was devastating for the densely packed Austrian battalions. In order to put even more pressure on the enemy, the French battery was ordered to advance steadily, while maintaining the most intense fire. This move soon forced Kollowrat to begin pulling his forces back. Meanwhile, however, the Austrian artillery was releasing sustained counter-battery fire with the six and eight-pounders that formed Kollowratt's and Liechtenstein's Corps artillery. But it was above all the murderous enfilade fire, coming from the two 12-pounder batteries near Wagram, barely one kilometer away, that did the most harm to the French artillerymen. Soon, some French gun crews were reduced to such a point that Napoleon asked for volunteers among the Guard infantry, in order to replace the losses. Discarded artillery matches soon lit up the ripe corn crops and some of the wounded on both sides, unable to crawl away to safety, burned alive where they stood.


title: Battle of Wagram

text: While the cannon were roaring, "Maréchal" Masséna was near Raasdorf, forming his men for their march south. Towards 11:00, he rallied many of the men who had routed during the attack on Aderklaa and then had rations of brandy distributed, in order to boost morale. With a part of his troops still fighting to keep Aderklaa, Masséna directed his men towards Essling, aiming to threaten Klenau's Corps, which was by now in an advanced position behind the French line, but which had made no attempt to threaten the rear of Napoleon's army. The passive posture of the Austrian Corps was due partly to a lack of orders to advance further and partly to the fact that Klenau's relatively small force was by now out of touch with the main Austrian force. Nevertheless, Masséna's task remained daunting. Some of his troops had to march no less than eight kilometers in vulnerable column formations, moving along the front of an enemy who had deployed numerous cavalry and artillery. Masséna displayed his usual skill and tenacity, using his available cavalry to screen his men and taking advantage of the high corn crops to hide his advance. The French troops, although out of range from enemy musketry, were under constant bombardment from the Austrian artillery. The Austrian cavalry attempted an attack, which nearly reached the carriage of Masséna, whose aides were forced to draw swords and defend him as French cavalry stepped in to repulse their Austrian counterparts. Towards noon, after marching some six and half kilometers in 90 minutes, the leading elements from Masséna's Corps, namely Marulaz's cavalry and Legrand's infantry were within sight of the enemy-occupied village of Essling.


title: Battle of Wagram

text: While battle was raging on the western side of the battlefield, some 10 kilometers to the east, "Maréchal" Davout was preparing his attack, the manoeuvre with which Napoleon intended to win the battle. In order to gain a foothold on the plateau before him, Davout had to drive back the forces of Rosenberg's Austrian IV Korps. The two forces had already clashed during the abortive night attacks the day before and again earlier that morning, between 05:00 and 06:00, when Rosenberg made a surprising attack, which the French managed to repulse. Due in part to the fact that Austrian Corps on other sectors of the battlefield failed to attack at the same time, Rosenberg was forced to draw his troops back to their initial positions, occupying the plateau and the strategic village of Markgrafneusiedl, situated just below the escarpment. This village was the key position, which Davout had to take at all costs, in order for his manoeuvre to succeed. Despite his vast numerical superiority, Davout's mission was not easy, as the Austrians had a numerous cavalry and artillery available to support their infantry. Furthermore, the defensive position was solid, with the village of Markgrafneusiedl formed of sturdy stone houses and a number of large buildings, such as a disused stone church with a tall, conspicuous tower, a monastery and a mill, all of which constituted easily defendable structures. The only weakness of Rosenberg's position was its left side, where the plateau formed a gentle slope, descending northeast.


title: Battle of Wagram

text: While the French were preparing their attack, artillery on both sides opened up, with Rosenberg's batteries placed on high ground and at times behind earthworks. Despite the superior Austrian tactical position, after about two hours of bombardment, the French managed to put out of action most of the Austrian pieces and cause fast-spreading fires in the village of Markgrafneusiedl. The fact that the French artillery won its duel with the Austrian artillery was due in part to the larger number of French high-calibre pieces, but most of all to their superior concentration of fire, with the artillery of French III Corps and II Corps cooperating and creating a deadly crossfire. By 09:30, Davout's troops were in position and ready to commence their attack. Initial orders provided that Davout should send his four infantry divisions in a frontal assault northwards, but early that morning Napoleon changed his mind, after reconnoitering the position in person and noticing that he could take advantage from the weakness on the left of the Austrian position. The new orders stated that two of Davout's divisions, those of Gudin and Puthod, were to advance from Grosshofen towards Markgrafneusiedl, forcing Rosenberg to commit a part of his forces in order to meet them, while the remaining infantry divisions, Friant's and Morand's, supported by Grouchy's and Montbruns cavalry divisions, would storm the plateau from the east. This order caused a significant delay, as the troops had to move to their assigned positions eastwards and artillery bridges had to be built, in order for the divisional artillery to be able to cross the Russbach stream. Commanding the Austrian forces in this sector, Rosenberg could rely on reinforcements from Nordmann's Advance Guard, and a numerous cavalry under Nostitz, all of which were placed under his direct command. He was also counting on support from the east, with Archduke John's "Army of Inner Austria" set to arrive on the battlefield, but so far these badly needed reinforcements had failed to materialise.


title: Battle of Wagram

text: The French began their steady advance between 09:30 and 10:00, their movement hidden from view by the thick smoke resulting from the intense artillery bombardment. On the right, Montbrun's cavalry had already advanced towards Obersiebenbrunn, repulsing Fröhlich's Austrian cavalry elements and clearing the way for Friant and Morand, who began their enveloping manoeuvre against the enemy left. Rosenberg responded by redeploying his reserves to form a new flank: Mayer's brigade in first line, supported by Riese's brigade and Infantry Regiment 58 "Beaulieu". However, all these troops were drawn from Nordmann's Advance Guard, a Corps which had sustained heavy casualties the previous day. During this manoeuvre, Nostitz's cavalry, placed initially on the plain below the escarpment, were pushed back and forced up the slope of the plateau by Grouchy's and Pully's dragoons; the Austrian horse subsequently redeployed to protect Nordmann's flank. Meanwhile, Davout personally led forward the divisions of Gudin and Puthod, who were to storm Markgrafneusiedl frontally. The village was defended by three Austrian brigades (Weiss, Hessen-Homburg and Swinburn), supported in second line by Infantry Regiment 3 "Erzherzog Karl" and the "Landwehr" battalion "Unter dem Manhartsberg". The Austrian first line met the advancing columns of Gudin and Puthod with steady fire, which forced the French attack to a temporary halt. Further east, Morand, leading the French attack, faced a similar fate, when the Austrians launched a combined infantry and cavalry attack which forced the French to draw back and reform. The first Austrian line, the two regiments from Mayer's brigade, the 4th "Hoch und Deutschmeister" and 49th "Kerpen", supported by eight squadrons of hussars from the "Erzherzog Ferdinand" regiment counterattacked and Morand's frontline regiments, the 13th Light and 17th Line were momentarily in a difficult situation. However, Friant was quick to react in support of his fellow commander, sending the Gilly brigade against the now exposed flank of the Austrians. At this point, "Feldmarshalleutnant" Nordmann intervened in person to reestablish the situation and was mortally wounded while doing so, with the Austrian counterattack in this sector failing completely. The brave Nordmann was to be discovered moments later by the French in a ditch, where he was abandoned during the hasty retreat of his men, who sought refuge behind Riese's brigade, where they reformed. Despite being present in large numbers, the Austrian cavalry failed to launch a massed charge and instead launched several small-scale charges, which produced little effect. At this crucial juncture, Friant committed his entire division and, despite the failure of a first attack, soon managed to gain a firm foothold on the escarpment, pushing towards the tower at Markgrafneusiedl, a sign that the battle in this sector was turning in favour of the French.

text: In the meantime, Gudin and Puthod had also rallied their men and launched them in another attack against Markgrafneusiedl. They were met this time by Rohan's division from Rosenberg's IV Korps, which valiantly attempted to hold its ground, in a stubborn house-to-house defense, despite the fact that village was by now largely engulfed in flames. The French were equally determined and even senior commanders exposed themselves to the greatest dangers (Davout's horse was shot under him and Gudin was seriously wounded) in order to give heart to the men. French pressure and the fast-spreading fire forced Hessen-Homburg's brigade, which had been drawn up in support of Rohan's division, to evacuate the position and reform on the escarpment behind the village, closely followed by Gudin's skirmishers. Combat did continue around the disused church, where Riese's battered brigade, infantry regiments 44 "Bellegarde", 46 "Chasteler", 58 "Beaulieu", nine battalions in total, was still holding out with remarkable tenacity and despite the fact that their commander, "General-Major" Riese, did not bother to show himself throughout the day. The church, with its conspicuous stone tower, was finally lost by the Austrians towards noon, when Friant managed to push through and link up with Gudin and Puthod, forcing the three Austrian regiments to withdraw, in order to avoid being outflanked. When Rosenberg failed to retake the tower with Hessen-Homburg's brigade, he decided to redeploy his entire force further back on the plateau and form a new line. This timely action temporarily stopped any further French advance. Seeing this development, Davout chose to force a decisive breakthrough and committed his ultimate reserve, the 3rd Heavy Cavalry Division. The Marshal ordered the heavy cavalry up the plateau west of Markgrafneusiedl, in an immediate frontal assault against the enemy line, rather than on the more favourable cavalry terrain east, where Grouchy, Pully and Montbrun were already operating. The 3rd Heavy Cavalry Division, a unit that the Emperor had attached to III Corps that very morning, was led by 31-year-old "Général de Division" Arrighi de Casanova, who had no previous command experience at divisional level. The division was formed of four cuirassier regiments, the 4th, 6th, 7th and 8th, totaling 16 squadrons and almost 2,000 men. Receiving his orders to charge immediately, Arrighi hastily formed his squadrons and led forward Bordessoule's brigade up the slope, but once there, he found himself in the middle of enemy barricades and was, according to his own account, unable to deploy a single squadron. The steel-clad cuirassiers made several attempts to break the sturdy Austrian masses, but the terrain was not proper for such action and their best attempts came to nothing. Taking some 300 casualties after several frustratingly ineffective charges, Arrighi pulled his men back to safety down the slope and furiously set off to find Davout and protest against the orders he had given.


title: Battle of Wagram

text: It was just after noon and, despite the failure of the French cavalry assault, Rosenberg was aware that his beleaguered line was about to give way, with possibly catastrophic consequences for the entire Austrian army. With his entire force already committed and no reserves, the Austrian commander could do little to prevent the seemingly unstoppable French onslaught. It was at this decisive moment that Archduke Charles personally brought reinforcements to his battered left wing: five battalions from Infantry Regiment 57 "Joseph Colloredo" and 15 "Zach", one battery of six-pounders, all drawn from Austrian II Korps and four squadrons of hussars, as well as the entire 8th "Hohenzollern" Cuirassier regiment, from the Cavalry Reserve. With the cavalry thus reinforced and placed under the overall command of "Feldmarschalleutnant" Nostitz, Archduke Charles ordered his horsemen to charge the enemy. At first, "General-Major" Wartensleben's brigade, the 3rd "O'Reilly" "Chevaulegers" and the 6th "Blackenstein" Hussars, charged Montbrun's first line, overwhelming the French 7th Hussars. The Austrians then made a dash towards Montbrun's second line, which made a surprising attempt to drive off the attackers with a carbine volley, which failed to break the impetus of the charge and sent the French horse reeling. As a result of his successful charge, Wartensleben was able to capture ten French horse artillery pieces. But the Austrian triumph was fleeting and Montbrun had carefully prepared a countercharge with his reserve and skilfully launched the 12th "Chasseurs-à-Cheval" frontally, while the 11th "Chasseurs-à-Cheval" charged the "O'Reilly" "Chevaulegers" from flank. On the French side, Grouchy soon brought his dragoons in support and Nostitz was forced to counter them by committing "General-Major" Rothkirch's brigade, formed by the 1st "Erzherzog Johann" and 6th "Riesch" Dragoons. A massive, albeit brief, cavalry clash occurred and in the melee, both Nostitz and Rothkirch were wounded and the Austrians were driven back, leaving behind the cannon they had captured moments earlier and taking refuge behind the infantry. This was the major cavalry action of the battle and, despite the fact that the Austrians committed over 30 of their 40 squadrons present in the sector, the French gained the upper hand, thanks largely to their superior training for massed action. Charging by single regiments against an enemy who committed entire brigades and divisions in coordinated actions, the Austrians, although superior in overall numbers, had been overwhelmed, a testament to their chronic inability to coordinate large-scale cavalry charges. Towards 13:00, after the failure of his cavalry charge, Rosenberg reckoned that he was unable to hold out on his current positions and began organising a fighting retreat towards Bockfliess, some northwest.


title: Battle of Wagram

text: Davout's successful flanking manoeuvre did not escape unnoticed. Despite the considerable distance, towards 13:00, Napoleon could see through his spyglass that the smoke line in Davout's sector was by now well beyond the clearly visible tower at Markgrafneusiedl, a sign that his men had managed to roll back the enemy's flank. With his left now stabilised following Masséna's successful disengagement, the Emperor began issuing orders for a general attack. Masséna was to continue his march south and vigorously attack Klenau around Aspern, Oudinot was ordered to prepare his Corps for an assault against the plateau and dislodge Austrian II Korps, Eugène was to take VI Corps against the enemy forces at Deutsch-Wagram, while MacDonald's V Corps was to draw closer to Aderklaa. During the night, MacDonald had been rejoined by the second division of his Corps and although theoretically 23 battalions strong, this force had diminished complements and could barely muster 8,000 men. With this force, MacDonald was preparing to execute Napoleon's previous orders to storm the plateau near the village of Wagram, much at the same location where he had attacked the previous day, when he received new orders. These provided that MacDonald's force should head west, towards Aderklaa, and deploy to occupy the ground held by the Grand Battery.


title: Battle of Wagram

text: Just before 13:00, MacDonald moved towards his assigned location, with eight battalions from Lamarque and Broussier's division deployed in line, forming the front line, with the other 15 battalions remaining in column, a formation which could more easily fend off the increasing menace poised by the numerous enemy cavalry. This unusual formation, some 800 metres long and 550 metres wide, was to be supported by the remains of the Grand Battery, which had orders to advance on its right and open intense fire against the Austrian line. Seras's division was also ordered in support of this attack and deployed some distance behind the column with one of the "carabiniers-à-cheval" regiments protecting its rear. The assigned objective of this prodigious mass of men was to bludgeon its way forward and take the village of Süssenbrunn, the seam between the Austrian Grenadier Reserve and III Korps. Once managed to take the position, they would drive a wedge between the two Austrian formations, pushing them apart. A powerful cavalry force was to protect either flank of MacDonald's formation, with Walther's mighty Guard Cavalry Division protecting the right and Nansouty's 1st Heavy Cavalry Division protecting the left. Sahuc's diminished cavalry division from the "Army of Italy" was also involved in this action.


title: Battle of Wagram

text: As MacDonald's lumbering column moved forward, Austrian artillery opened up against the accompanying French cannon, disabling 15 of them, before they even had time to unlimber and respond. The Austrian guns then focussed on MacDonald's slow-moving formation, whose deep ranks presented ideal targets. Seeing the French advance, Archduke Charles ordered his Corps commanders to refuse the flank of the Grenadier Reserve and III Korps. Liechtenstein ordered Steyer's brigade to deploy in an oblique position and release heavy musketry against the right flank of the advancing French column, while Kollowrat issued a similar order to the Lilienberg brigade, which fired musketry volleys against the left of MacDonald's men, while Austrian artillery was pounding the column's front line. However, by now the French had managed to dent the Austrian line and had only a few hundred metres to go before they could reach the strategic village of Süssenbrunn. With his force reduced to little more than half strength and his battalions forced to form square in order to fend off three successive cavalry attacks from "Feldmarshalleutnant" Schwarzenberg's cavalry, MacDonald could go no further. He called upon the numerous cavalry available to charge and clear the enemy guns and infantry, who, according to his own account, were by now in a state of complete disarray and ripe for destruction. On his left, Nansouty, who had apparently not been consulted regarding the placement and role of his division in the attack, had kept his men too far back, in order to protect them from the sustained enemy fire. When Nansouty arrived with his cuirassiers, the Austrians were prepared to meet them and the guns had already limbered and moved away to safety. The French cuirassiers charged Vukassovich and Saint-Julien's divisions, but these men were by now formed in the sturdy mass formations, which were virtually invulnerable to cavalry.


title: Battle of Wagram

text: Further north, protecting the other flank of MacDonald's column lay the fresh Guard Cavalry Division, which also received MacDonald's invitation to charge, but remained motionless, with its commander, "Général de Division" Walther, invoking a lack of orders from his direct commanders, either Napoleon or "Maréchal" Bessières. The Emperor was too far away from the action and Bessières had been wounded during his earlier cavalry charge and had been carried away from the battlefield, so the Horse Guards did not move. Towards 14:00, MacDonald's attack had ground to a halt and the opportunity to completely break the Austrian line in this sector came to nothing. Napoleon noted with disgust that it was the first time that the cavalry let him down, but, given the state of exhaustion and the losses sustained by the French forces, MacDonald would have probably been unable to follow up any breakthrough achieved by the cavalry anyway. Still, the resolutely led attack achieved Napoleon's main strategic goal, which was to pin down the Austrian forces in this sector, preventing Charles from reinforcing his battered left. Forced to concede that his attack had lost momentum, MacDonald did his best to shelter his remaining men from the enemy's intense cannonade. However, reinforcements were not far away: the Emperor sent in support Wrede's powerful Bavarian division, 5,500 men strong, as well as the elite "Chasseurs à Cheval" and "Chevau-légers" regiments of the Imperial Guard, as well as the Saxon cavalry. The Bavarian division quickly came up in support but exchanged fire with the enemy only briefly and it was solely the artillery that really came into action, as the Austrians were by now in full retreat. Behind the Bavarians came the Fusiliers of the "Young Guard", four battalion-strong, which were led by the Emperor's aide-de-camp, General Reille, with strict orders to avoid "getting involved in any adventure". With the support of the Guard, the Bavarians captured Süssenbrunn and they alone continued the pursuit beyond this village. The Guard "Chasseurs à Cheval" tried to halt the advance of the enemy but they were met by Liechtenstein's Austrian cavalry and, receiving no support from their fellow "Chevau-légers", they had to withdraw, coming away with only three enemy cannon.


title: Battle of Wagram

text: Meanwhile, Masséna had indeed made remarkable progress since 11:00, when he had begun disengaging from the struggle at Aderklaa and organising his march against Klenau. On the French left, Klenau, commander of VI Korps, was fully aware of Masséna's manoeuvre, stating in his post-battle report that he saw an "Infernal Column" advancing towards him. By 12:30, elements of IV Corps were at Essling and Masséna received the Emperor's dispatch, informing him of Davout's success and urging him to attack. Masséna sent Marulaz's cavalry to clear the enemy horse, which was pushing back Boudet's defeated division. Then, Marulaz fell upon and captured the Austrian battery which was bombarding the bridges over the Danube, sending the panicked gunners fleeing for their lives. An Austrian countercharge from Walmoden's Austrian hussars sent the French horse reeling and recaptured the lost battery, managing to carry most of it, except two guns, to safety, before more French cavalry, this time from Lasalle's division, came up against them. The French cavalry attack halted the advance of Klenau's Korps and allowed the French launch an attack of their own against the village of Essling. Six weeks before, during the Battle of Aspern-Essling, the French had valiantly defended this village against several Austrian attacks; now they were ordered to take it from some 1,200 whitecoats. The village was in ruins, but the sturdy stone granary was still standing and represented a formidable defensive structure. Nevertheless, Ledru des Essarts's brigade from Legrand's 1st division stormed the position and, after intense fighting, they secured Essling towards 14:00, sending the defenders fleeing towards Aspern. Masséna then took Aspern after a brief combat and, collecting his four infantry divisions, continued to press Klenau, sending Molitor's division towards Breitenlee. There, General Durutte's division of the "Army of Italy", which had been sent to plug the gap between IV Corps and the rest of the army, had just taken the village of Breitenlee. Durutte's division was able to link up with Molitor.


title: Battle of Wagram

text: Masséna had accomplished his mission and had no further orders to continue his action but, hearing the intense cannonade on his right, he understood that he needed to continue his attack. He detailed Boudet's division to march on Kagran, while his other three infantry divisions marched on Leopoldau. The corps cavalry preceded the infantry and Lasalle's squadrons caught up with Klenau's infantry near Leopoldau. There, the French cavalry met two Austrian battalions, already formed in solid masses. This formation was ideal for fending off enemy horse. Nevertheless, the French charged impetuously but achieved little. The first mass could only be dispersed after horse artillery came into action. Not long before 17:00, the cavalry moved against the second mass and it was during this action that the gallant Lasalle, one of the best cavalry commanders of his time, was shot dead. Marulaz took overall command of the cavalry and personally placed himself at the head of the 8th Hussars, in a bid to avenge the slain commander; the attempt failed and Marulaz was himself wounded and had to be carried away to the rear. This event, as well as the fact that the French were now under fire from the artillery of Austrian V Korps on Bisamberg heights, convinced Masséna to halt his pursuit. Towards 17:00 Klenau had succeeded in extracting his corps from the dangerous position next to the Danube and moved to relative safety behind the reserve V Korps, deployed on the Bisamberg heights.


title: Battle of Wagram

text: While "Feldmarshalleutnant" Klenau was being ousted from Essling, Archduke Charles received much-awaited news about the arrival of his brother on the battlefield. However, the news were disappointing: Archduke John of Austria and his 13,000 men, Charles's only hope for rescuing his collapsing left flank, would only be able to arrive towards 17:00, much too late to make any difference. By now, Charles was acutely aware that his troops would not hold out much longer. His three corps on the Wagram plateau (I, II and IV) had been in action for some ten hours. On his right, Kollowrat's III Korps, Klenau's VI Korps and the Reserve Korps were being pushed back. Crucially, he had no battle reserves with which to either support his battered line or to launch a counterattack of his own. Continuing to fight in these conditions would have spelled the end of the "Kaiserlich-königliche Hauptarmee" and, in Charles's view, the end of the Habsburg Empire. His only realistic option was to begin an orderly retreat, which he ordered by mid morning, directing each corps along its line of retreat.


title: Battle of Wagram

text: While MacDonald's attack was drawing the attention of the Austrians, the French launched their general attack. Napoleon committed Marmont's fresh XI Corps, sending these men to take position opposite to Austrian I Korps and fill the gap between the "Army of Italy" and II Corps. Moreover, towards 13:00, the French from Oudinot's II Corps had begun to advance frontally against the Austrian troops on the Wagram plateau. The mercurial Oudinot, who had been waiting for his orders to attack all morning, decided to wait no longer, despite the fact that he had not yet received his order. Opposite to Oudinot was Austrian II Korps. Having spent the entire morning doing nothing else than exchanging artillery fire with French II Corps, these men were relatively fresh. They were also in a very dangerous position. The commander of II Korps, the experienced "Feldmarschalleutnant" Hohenzollern, could see that his force was in danger of being attacked from the flank by Davout's seemingly unstoppable corps. Now Oudinot was advancing against him. At first, Hohenzollern tried to hold on his initial positions and his men greeted Oudinot's advancing columns with intense musketry. However, the Austrian commander realised the fragility of his position, seeing that, on his left, all the Austrian troops were in full retreat and he ran the risk of having Oudinot pin his men down, while Davout was free to advance in his flank and rear. Hohenzollern thus had little choice but to order his men to fall back and form a new line further north, sending 5 battalions and several batteries from his second line to form a new flank and slow down Davout's two advancing divisions, which were drawing dangerously close to the strategic village of Baumersdorf.


title: Battle of Wagram

text: Seeing the Austrians in full retreat, Oudinot lost his composure and galloped along his line, shouting his commands, ordering his men to run at the enemy. One of the Corps divisional commanders, general Grandjean, reiterated this highly unusual and potentially disastrous order, which would have resulted in the columns rapidly dispersing and becoming vulnerable to a counterattack. Luckily enough, the troops were commanded by experienced junior officers, who took over and executed the orderly manoeuvres that were required on such occasions. During this action, Oudinot was wounded twice and had his horse shot from under him, but he retained his command and, after his surgeon dressed his wounds, he led his men on. His troops stormed Baumersdorf, which they took, despite gallant defense from Hardegg's brigade. Oudinot's Corps then fanned out, with the bulk of his men continuing to press Hohenzollern and Tharreau's division wheeling left against Bellegarde's I Korps. To the west, General Pacthod and his division of the "Army of Italy", supported by the Italian Royal Guard, were able to manoeuvre unseen by following the riverline of the Russbach up the village of Deutsch-Wagram. There, they fell upon the unprotected flank of d'Aspré's Austrian grenadier division, which had been left behind to cover Bellegarde, who had just begun to retreat, in accordance with Charles's orders. Surprising the grenadiers, Pacthod stormed the position and pushed the Austrians back in disorder beyond the village of Aderklaa. They were supported by Tharreau's division of II Corps, which had managed to storm the plateau next to the village. Bellegarde reacted by sending in some of his reserves to stop the enemy onslaught, but the French managed to secure both Wagram and Aderklaa, two key positions on the battlefield.


title: Battle of Wagram

text: By 16:00, the entire Austrian army was in full retreat. They executed this manoeuvre admirably, with the formations remaining cohesive and withdrawing in echelon, each formation protecting the retreat of the adjoining one. During this phased retreat, "Generalmajor" Smola, commander of the Austrian artillery had a major role, managing to mass a sufficient number of cannon to keep the enemy at a respectable distance. The French, who had been marching and fighting for over forty hours, under intense heat and with scarce rations of water and food, were slowly following the retreating enemy. The exhaustion of the French troops was such that, towards 16:00 a brief moment of panic occurred at Wagram. Dozens of French infantry fled down the escarpment, with the Old Guard forced to form square in order to protect the Emperor's headquarters, before order could be restored. A second such moment took place around one hour later, when a mounted scouting party from Archduke John's army suddenly appeared near Glinzendorf, causing panic among the stragglers and civilian contractors of the army, with the Guard again forced to form square. But John soon received word that the battle was already over and hastily retraced his steps. A final incident took place towards 18:00, when elements of the 108th Line regiment from Davout's Corps caught up with enemy stragglers at the Bockfliess. There, the French found the houses filled with drunken Austrian whitecoats, who refused to surrender and attempted to defend themselves. Some 200 of these men were slaughtered and 400 were captured. By nightfall, contact had been broken and the exhausted French had to stop the pursuit and camp on their positions. Towards dusk, French cavalry caught up with Austrian III Korps and tried to block its retreat but the numerous Austrian cavalry in the sector promptly stepped in, hitting the enemy's flank and sending these horsemen fleeing. This persuaded Archduke Charles that he had left III Korps in an exposed position and ordered it to hasten their retreat and get in line with VI Korps. Towards 20:00 all combat ceased and the Austrians were able to move away without any further incident. Napoleon had won the great Battle of Wagram.


title: Battle of Wagram

text: By nightfall on 6 July, the Austrians, still capable of action, had broken contact with their pursuers and Charles had managed to reestablish a cohesive, albeit irregular front. The remarkable combat-worthiness shown during the evening fighting left Napoleon wondering whether the Austrians would actually renew battle the next day. The Emperor rose early on 7 July and reconnoitred the battlefield in person, noting the huge losses in men on both sides and seeing that the Austrians had withdrawn. He then returned to more practical matters and, after receiving MacDonald's report, he suddenly embraced the general and elevated him to the dignity of "Maréchal d'Empire", the only Marshal to receive the title on a field of battle. The Emperor also criticised Marmont for his slowness in arriving on the battlefield and told Oudinot that he ought to have him shot for attacking without orders. The French resumed their pursuit towards 14:00, as the extreme exhaustion of the army prevented an early start. Their artillery had fired somewhere between 90,000 and 100,000 rounds during the battle, which left the caissons empty and it took some time before they could be refilled. Among the rank and file, there were even instances of severe breakdown in troop discipline, as the army moved through county packed with vines and wine cellars. When an incensed Oudinot, sabre in hand, tried to restore discipline among a group of drunken cavalrymen from his army corps, he was almost attacked by his own men. Pursuit was further complicated by the absence of reliable information about the exact direction of the Austrian retreat. Contradictory intelligence collected by the various Corps confusingly stated that the Austrians were retreating either towards to Brünn or to Znaim and other reports were actually indicating a retreat towards Moravia. The French tried to close the gap through sustained march. Spearheading the pursuit were the army corps of Masséna to the west, Marmont in the centre and Davout to the east, while the "Army of Italy" was detailed to keep an eye on Archduke John's army.
